Данные по флоре России: указываем лицензии для своих наблюдений, это важно!

Дорогие друзья!

Если вы упомянуты в этом посте, то у ваших наблюдений по флоре России по той или иной причине не указана лицензия. Напоминаем, что пометка "Все права защищены", которую выбирают некоторые пользователи для своих фотографий (ранее она ставилась по умолчанию), отныне не рекомендуется к использованию директоратом iNaturalist: всех участников платформы настоятельно просят указать в профиле одну из доступных лицензий. Мы традиционно рекомендуем лицензии CC0, CC-BY или CC-BY-NC, чтобы ваши данные были доступны в GBIF.

Все подробности того, что такое лицензии и как их поменять у своих фотографий, подробно описаны Скотом Лоари, со-директором iNaturalist. Для указания лицензии всех своих наблюдений вам нужно будет зайти в настройки учётной записи на сайте - в приложении поменять лицензии нельзя.


Ниже перечислены участники, у которых все наблюдения не имеют лицензии или (в редких случаях) имеют лицензии, отличные от CC0, CC-BY или CC-BY-NC. Заодно приглашаем всех участников iNaturalist подписываться не только на проект МГУ "Флора России", но и на региональные страницы этого портала, на антипроект (бэклог) и "серую зону".

Next steps after making an observation

Hi everyone!

First of all I'd like to say a big thank you to everyone whose joined the project, we wouldn't be able to find the answers without you. Secondly, congratulations to everyone for submitting 30 observations since the project was available online just over a month ago! An incredible start!

If you have made an observation, and want to know what to do next, here are a couple of options:

  1. Keep an eye out for Rainbow lorikeets feeding on other plants/food sources in your area! Let us know by making additional observations for each plant/food source you observe Rainbow lorikeets feeding on.
  2. Tell us when the Rainbow Lorikeets return to your tree/plant/food source! To help us determine what rainbow lorikeets are feeding on at different times of the year, and to save you adding new observations of rainbow lorikeets feeding on the same tree, you can simply EDIT your observations! After you have made an observation of a particular tree/plant species on iNaturalist, you can simply edit your observation to add in new dates and times you have observed the rainbow lorikeets coming back to the same plant.
To do this, follow these steps:
  1. Go into your profile, which can be found in the top right-hand corner of the iNaturalist web-page
  2. Click the heading ‘Edit observations’
  3. Choose the observation with the plant species you have seen the Rainbow Lorikeets revisit (e.g. Crimson Bottlebrush at Dunrossil Park on 23rd July)
  4. Once in the observation, click the blue ‘Edit’ icon found at the top right-hand side.
  5. In the ‘Notes’ section, found on the left-hand side, please right the date and time you observed Rainbow Lorikeets revisiting this tree/plant species (e.g. 28/06/2021 8:15am).
  6. Once the edit has been made, scroll down and click the blue ‘Save observation’ down the bottom of the page.

Keep Safe and Happy Rainbow Lorikeet Spotting!

Winter to Spring

A number of snow showers in the last third of Winter. I shoveled snow on the back patio into the garden below the Magnolia. Piled a couple feet high and didn’t melt. Kept the Snowbells from view at their usual time. This was the second year that my Winter Aconite failed to appear.

Cleaning gutters while standing on the garage roof in late March, I saw 2 bumblebees, presumably Queens, hovering around the roof ridge of the house and wondered if they would find a way into the attic to nest. A Cabbage White butterfly was also flying around and landed on new growth sage prior to blooming. Determined to plant earlier pollinator friendly plants. This could be accomplished by planting in unused washtubs currently used for collecting rain water and placed in the fenced in back patio so they wouldn’t be stolen. Hopefully bloom before the Magnolia in order to receive adequate sunlight. Planted some Hellebores and Bleeding Heart, then later, Globe Thistle and Wood Poppy. My Lungwort started to bloom but was snuffed out by a couple cold nights. Will plant some Snap Dragons next Spring.
In April, saw what I thought was an early Honeybee, but it was a Mason Bee.I had a second Mason Bee House on the back patio, and she worked tirelessly while I cleaned up the early Magnolia Blooms. Should have taken video of her. Guess she might have used the flowers on the tree for nectar and pollen, but also saw her in the Archangel. Bluebells followed shortly in the garden and barrel but too late for her efforts.
I pulled pots out of the garage and over time saw evidence of Milkweed and Joe Pye returning. Cleaned up the Catmint and eventually placed pots out front in the sun with the Magnolia leaves starting to block the sunlight. Time to fill the Hummingbirds feeder, but did not see any early. Time to start working on the front Pollinator gardens, as well.

Signage!

New identification signs are beginning to be placed! Look for them tucked into bushes and wildflowers on your walks. Happy learning neighbors!

Variación en los ojos del Gavilán de Cooper

El color de sus ojos va desde un amarillo claro a naranja intenso, hasta un profundo rojo. El Gavilán de Cooper (𝘈𝘤𝘤𝘪𝘱𝘪𝘵𝘦𝘳 𝘤𝘰𝘰𝘱𝘦𝘳𝘪𝘪) presenta esta variación en el iris. Así como su plumaje, el color de sus ojos cambia en función de la edad. De acuerdo a estudios, el iris rojo lo presentan individuos de mayor madurez, y este es alcanzado más rápido en los machos.
.
En algún momento se pensó que el iris rojo brindaba mayor probabilidad de formar pareja, idea que no ha logrado ser probada. Pero un experimento brinda evidencia de que el color amarillo y naranja es presentado durante mayor tiempo en las hembras, esto se debe a que las hembras son las que regularmente alimentan a los polluelos. Según el experimento, en sus primeros días los polluelos activamente se ven atraídos a picotear objetos rojos, como la carne, el hecho de que las hembras porten durante mayor tiempo ojos amarillos, disminuye el riesgo de que sus ojos sean picados por los polluelos.

Se piensa que esta condición evolutiva se presenta en los demás gavilanes del género 𝘈𝘤𝘤𝘪𝘱𝘪𝘵𝘦𝘳, y también en el Gavilán rastrero (𝘊𝘪𝘳𝘤𝘶𝘴 𝘤𝘺𝘢𝘯𝘦𝘶𝘴), en el cual los machos llegan a tener un iris rojo en tan solo un año, mientras a las hembras les toma cerca de 6 años.

2.a. Red Osier Dogwood - Cornus sericea or Cornus stolonifera

Stems: The bark and twigs are reddish to purple and fairly smooth from autumn to late spring; after the leaves have fallen, the deep burgundy branches add color to the winter landscape. The bark, twigs, and leaves are bright green in spring through summer.
Leaves: The simple, opposite leaves are 2-4 in long, with smooth margins, rounded bases, pointed tips, and falsely parallel veins.
Flowers: Arranged in a cluster of small white to cream-colored flowers. Flowering occurs from June to August.
Fruit: White berries, smooth on the faces, furrowed on the sides. The fruit ripens in late summer, and besides being available through the fall, some of the berries may persist on the plants into the winter months.
Uses: Wildlife browse the twigs, foliage, and fruits. A large variety of birds eat the fruit, from Cedar Waxwing to Grouse. The shrubs provide excellent nesting habitat for songbirds. Mammals that eat the fruit and foliage include bear, beaver, rabbits, raccoons, squirrels and more. Other mammals like deer and elk browse the twigs and foliage.

3.b. Cedar Waxwing - Bombycilla cedrorum

Learn more about identification here: https://www.inaturalist.org/taxa/7428-Bombycilla-cedrorum

3.a. Kinnikinnick or Bearberry- Arctostaphylos uva-ursi

Stems: A long, flexible stem comes from a single root system and branches into a system of trailing stems that may send out roots periodically. The textured branches are initially white to pale green, becoming smooth and red-brown with maturity.
Leaves: Simple, evergreen leaves, alternately arranged on branches. Each leaf is held by a twisted leaf stalk, vertically. The leathery dark green leaves are an inch long and have rounded tips tapering back to the base. In fall, the leaves begin changing from a dark green to a reddish-green to purple.
Flowers: Terminal clusters of small bell or urn-shaped, white to pink flowers. Bloom from May to June, Fruit: Round, fleshy or mealy, bright red to pink fruits called drupes. This smooth, glossy skinned fruit will range from 1/4 to 1/2 inch in diameter. The fruit will persist on the plant into early winter.
Distribution: This long-lived, low growing shrub is very cold tolerant. This plant prefers coarse, well to excessively drained soils of forests, sand dunes, bald or barren areas. It does not tolerate moist or off-drained sites. Although bearberry is often found growing in the open on sand dunes, it grows well under partial shade of forest canopies.
Uses: The fruit is eaten by a few species of songbirds and game animals. Deer will sometimes browse the foliage lightly.

Learn more about identification here: https://www.inaturalist.org/taxa/68049-Arctostaphylos-uva-ursi

4.a. Sitka Mountain Ash - Sorbus sitchensis

Leaves: Winter buds and young growth are covered with rusty-red hairs and are not sticky. Pinnately compound leaves have 7-11 bluish-green leaflets.  Leaflets are rounded at the tip and coarsely toothed from ¾ of the margin to the tip – to nearly entire.
Flowers: White flowers are borne in round-topped clusters.
Fruit: Pinkish to orange-red berry-like clusters.
Distribution: Grows 3-12 feet (1-4m) in open forests, clearings, streambanks, and avalanche slopes; often on drier, nitrogen-poor soils.
Uses: Sitka Mountain Ash fruit remains on the plant until late winter, making it valuable as winter forage for many upland gamebirds, songbirds, and small mammals.  The foliage and twigs are browsed by deer and elk. Black bear and grizzly bear also eat the berries, leaves, and stems. Flowers are pollinated by insects. It is useful for streambank revegetation projects.

An American Pika Doing its Thing - (Belated) Observation of the Week, 7/20/21

[It took a little time for Prof. Meredith to get back to me, so this is being posted a few weeks late.- Tony]

Our Observation of the Week is this American Pika (Ochotona princeps), seen in the United States by @drbrachydactyl!

“I carry my cameras on all the hikes I go on (because you never know what you might see), and I look for and notice animals everywhere I go at all times,” says Professor Stephanie Meredith, who studies primatology. She tells me she’s always loved animals but became a primatologist “because I'm really into behavior and especially enjoy observation,” which comes out in her recounting of her pika observation.

My wife and I were hiking in the eastern Sierra (it's so lovely there) for the first time and we saw three pika on the Little Lakes Valley trail by Rock Creek. My wife spotted the first one, but just for a split second and it was gone. I spotted the second and third. We spotted them all by motion, though the locals tell me that you can often hear them alarm calling. The second (the one pictured) was obliging with its photo ops. It was putzing around the rocks, foraging on plants, and for some reason when it would grab a mouthful of vegetation, it would return to a perch and munch there in full view. The reason I eventually got a good photo was simply because we watched it for long enough. I'm sure we watched it for at least 10 minutes, because it was the first pika we'd been able to see well enough to appreciate...

It was fun to watch a pika just do its pika thing--after all, you can hardly get cuter than a munching pika. And that's always my favorite--when you are lucky enough to just be quiet and watch an animal, large or small, do its thing without regard for your presence. 

While they may look like rodents at first glance, pikas (members of Family Ochotonidae) are actually lagomorphs, an order which includes rabbits and hares. American pika range throughout rocky mountainous areas of western North America and spend much of the year in their dens, living off haypiles they gather over the short summer. Very sensitive to high temperatures, they have likely been forced to higher altitudes as the climate warms.

Currently an anthropology professor at West Los Angeles College, Stephanie (above, in Iguazú National Park) is collaborating with Clara Scarry (CSUS), Marcela Benitez (Emory), and Sarah Brosnan (GSU)), researching cognitive development in black-horned capuchins at Iguazú National Park. She’s also “working to develop research opportunities for community college students,” and is considering using iNat as part of this endeavor.

“iNaturalist,” she says,

hasn't changed the way I interact with or see the natural world, but it has changed my sharing practices. I now diligently use iNaturalist to report herp sightings that I might otherwise keep to myself (for example, if a photo is only perfunctory, or maybe even kind of bad). I do this because I have some herpetologist friends who actually use iNaturalist for research purposes (Greg Pauly at the LA Natural History Museum) and because if I don't, some of my other naturalist/biologist friends (Tom Wake at UCLA) will chide me about it, lol. And that makes sense. It's great for documenting range changes through time, activity patterns across the year, etc.--all the kinds of stuff that ecologists want to know but that small teams of researchers really just can't document by themselves.

Técnicas de controlo de flora invasora: urge quantificar o seu custo e a sua eficácia

Existem diversas técnicas para eliminação de acácias e outras espécies exóticas invasoras, tais como

  • arranque,
  • corte e pincelagem com herbicida,
  • descasque,
  • corte recorrente.
O âmbito de aplicação destas técnicas não é exatamente igual:
  • algumas destas técnicas só são aplicáveis em plantas muito jovens (arranque), outras apenas em plantas com alguma dimensão (descasque);
  • algumas técnicas estão vocacionadas para pequenas áreas (descasque), outras poderão ser aplicadas em áreas maiores (corte e pincelagem, corte recorrente);
  • algumas técnicas poderão ser aplicadas em ações de voluntariado (arranque, descasque, corte de árvores jovens ou rebentos), outras terão de ser aplicadas por equipas especializadas com meios técnicos adequados (corte e pincelagem, corte inicial de árvores adultas).
Analisemos com algum detalhe as duas técnicas mais adequadas para o controlo de grandes manchas de acácias jovens: corte e pincelagem ou corte recorrente. Qual destas técnicas será mais eficiente? Qual destas técnicas deveremos privilegiar em locais com dezenas ou centenas de hectares de área invadida?
  • CORTE E PINCELAGEM: estimativa do custo por hectare em áreas invadidas por acácias jovens
Consideremos um local invadido por acácias com 2 ou 3 anos, germinadas após um incêndio recente, como acontece na Mata do Sobral (Serpins, Lousã: área ardida em outubro de 2017). As manchas de acácias existentes neste local são muito densas, podendo conter cerca de 25 jovens árvores por metro quadrado (equivalente a uma distância de 20 cm entre árvores numa grelha ortogonal). A técnica de corte e pincelagem exige que o herbicida seja aplicado imediatamente após o corte: bastarão alguns segundos (5 segundos?) para que se dê a "selagem" do corte, impedindo que o herbicida seja absorvido de forma sistémica. Assim, esta técnica terá de ser aplicada por duas pessoas, atuando numa planta de cada vez: é necessário cortar a árvore, afastar a árvore cortada e a motosserra ou outro instrumento de corte, pincelar o corte, derrubar a árvore cortada em segurança, aproximar a motosserra da próxima planta a cortar, etc.. Com grande otimismo, vamos admitir que toda esta sequência demora apenas 10 segundos. Nesse caso serão necessários 250 segundos por metro quadrado, o que corresponde a 2500000 segundos por hectare, equivalente a cerca de 700 horas. Também com grande otimismo, vamos admitir que o custo com o material é desprezável e que o custo total da mão de obra é de apenas 10 euros por hora e por pessoa: nesse caso o custo total por hectare será de 700x10x2 = 14000 euros. É pouco provável que a invasão por acácias fique resolvida com uma única intervenção: provavelmente algumas acácias irão rebentar, exigindo nova aplicação de herbicida ou cortes recorrentes que causem o enfraquecimento e a morte da planta. Tendo em conta esta necessidade de novas intervenções e tendo em conta que apenas tínhamos considerado o custo com mão de obra, concluímos que facilmente o custo total da eliminação de acácias por corte e pincelagem poderá ascender a 20 mil euros por hectare.
  • CORTE RECORRENTE: estimativa do custo por hectare em áreas invadidas por acácias jovens
Consideremos novamente um local com as caraterísticas da Mata do Sobral e admitamos que as acácias seriam eliminadas através de cortes sucessivos até ao enfraquecimento e morte das plantas.
  • As jovens acácias com 2 ou 3 anos poderão ter diâmetros até cerca de 4 cm e deverão ser cortadas com motosserra. No entanto, não havendo lugar à aplicação de herbicida, será possível cortar e derrubar várias árvores de uma vez e apenas será necessária uma pessoa. Admitamos que são necessários 3 segundos para cortar cada árvore, mais 8 segundos para derrubar em segurança cada conjunto de 4 árvores: no total serão necessários 20 segundos para 4 árvores, o que corresponde a um total de 5 segundos por árvore. O tempo total por metro quadrado será de 125 segundos e o tempo total por hectare será de 1250000 segundos, o que corresponde a cerca de 350 horas. Considerando um custo de 10€ por hora e por pessoa, esta primeira intervenção terá um custo total de 3500€/ha.
  • Estas acácias irão rebentar após o corte, sendo necessário cortar os rebentos periodicamente, de preferência antes de se tornarem lenhosos. Admitamos que o corte terá de ser repetido a cada 6 semanas e que as plantas demorarão pouco mais de um ano a morrer: poderá ser necessário cortar os rebentos 10 vezes após o corte inicial, recorrendo a uma motorroçadora. Este corte de rebentos deverá ser bastante rápido: talvez seja possível "varrer" um quadrado com 33cm de lado a cada 10 segundos, o que corresponde a cerca de 90 segundos por metro quadrado, ou seja, 900000 segundos por hectare. Este tempo corresponde a 250 horas: o custo com mão de obra no primeiro corte de rebentos será de cerca de 2500 euros. Entretanto o número de rebentos irá diminuir, levando a uma diminuição do tempo e do custo associado ao corte desses rebentos. Admitindo que o custo médio em cada um dos 10 cortes de rebentos seja de cerca de 1250 euros (uma vez que vai diminuindo de 2500 até zero), o custo total dos 10 cortes de rebentos será de cerca de 12500 euros por hectare.
  • O custo total da intervenção (corte inicial das árvores e 10 cortes de rebentos) será da ordem de 16 mil euros por hectare.
  • QUAL DAS TÉCNICAS É MAIS EFICIENTE?
As duas estimativas obtidas (20000€/ha no caso do corte e pincelagem, 16000€/ha para o corte recorrente) são da mesma ordem de grandeza: sendo meras estimativas, não permitem concluir qual destas técnicas é mais eficiente. No entanto, o corte recorrente apresenta algumas grandes vantagens relativamente ao corte com aplicação de herbicida:
  • não causa contaminação dos aquíferos com herbicidas (o que não só tem relevância ambiental como facilita a aceitação pela opinião pública),
  • permite minimizar os danos colaterais sobre a flora autóctone,
  • recorre a meios técnicos mais simples facilmente ao alcance de uma autarquia ou associação de produtores florestais,
  • requer mão de obra menos especializada (mais fácil de recrutar e possivelmente a mais baixo custo),
  • pode ser aplicado por voluntários (provavelmente com ferramentas de corte manuais em vez da motosserra ou motorroçadora),
  • é mais tolerante a falhas na sua aplicação (o corte com aplicação de herbicida, se não for corretamente aplicado, será totalmente ineficaz),
  • talvez seja possível reduzir o número de cortes de rebentos - e consequentemente o custo da intervenção - se o corte inicial for efetuado no final da primavera (imediatamente antes dos meses mais quentes e secos) ou no final do outono (imediatamente antes dos meses mais frios nos quais é comum a formação de geada): dessa forma muitos dos rebentos irão morrer por ação do calor extremo ou da geada, acelerando o enfraquecimento da planta.
Para decidir entre as duas técnicas de forma esclarecida, será necessário obter estimativas mais rigorosas para os diversos parâmetros considerados nos cálculos anteriores:
  • número de árvores por metro quadrado,
  • tempo necessário (em média) para o corte de cada árvore,
  • tempo necessário para a pincelagem de cada árvore cortada,
  • tempo necessário para o corte de rebentos (por metro quadrado),
  • número de cortes necessários ou número de aplicações de herbicida necessárias até à morte das plantas,
  • custo horário da mão de obra,
  • custo do equipamento, combustível, herbicida, deslocações, etc..
    Estes parâmetros terão de ser avaliados em diversos locais, com árvores de diferentes idades, manchas com diferentes densidades, solos com diferentes caraterísticas (mais rochosos ou mais arenosos, mais planos ou mais inclinados), etc..
    Não tenho conhecimento de que esta recolha de dados quantitativos esteja a ser feita - nem em intervenções concebidas especificamente para esse fim, nem em ações de voluntariado, nem nos projetos de controlo de flora exótica invasora atualmente em execução (por exemplo na Mata do Sobral).

  • SERIA VIÁVEL a aplicação de alguma destas técnicas para remoção das acácias na Mata do Sobral (cerca de 250 hectares inseridos na Rede Natura 2000)?
Entre agosto de 2019 e julho de 2021 foram realizadas centenas de observações de flora exótica invasora na Mata do Sobral, quase exclusivamente nos cerca de 250 hectares que integram a Rede Natura 2000. Na maioria dos locais de observação avaliou-se o grau de invasão na escala de 0 a 9 anteriormente definida. Essas observações foram registadas na plataforma iNaturalist e posteriormente exportadas e agrupadas em "quadrículas" com 0,001 graus de latitude por 0,001 graus de longitude (o que à latitude de 40 graus corresponde a cerca de 0,95 hectares). As observações realizadas em cada quadrícula foram ordenadas segundo o grau de invasão registado no momento da observação. Teoricamente os valores deveriam ser bastante uniformes em cada quadrícula, mas não é necessariamente assim - quer devido a incertezas na determinação da percentagem de área invadida num círculo de 1 ha em redor de cada observação, quer pelo facto de esse círculo não estar contido numa única quadrícula - sobretudo quando o local de observação se situa junto à fronteira da quadrícula. Nos casos em que o grau máximo de invasão registado numa quadrícula ocorria numa única observação e a diferença para todas as outras observações era superior ou igual a 3 níveis na escala de invasão, descartou-se essa observação por se considerar que não seria representativa do estado de invasão de toda a quadrícula. De entre os restantes valores do grau de invasão registados nessa quadrícula, considerou-se que o mais representativo seria o maior deles: provavelmente o local onde tinha sido realizada essa observação permitia ver a maioria das manchas de acácias existentes numa área de 1 ha em redor mas os outros locais de observação na mesma quadrícula não proporcionariam essa mesma visão de conjunto, conduzindo a uma sub-valorização da área invadida. Desta forma foram obtidos valores do grau de invasão em 261 "quadrículas" de 0,001 graus de latitude por 0,001 graus de longitude, correspondentes a cerca de 247 hectares, ou seja, praticamente toda a parte da Mata do Sobral que integra a Rede Natura 2000. Nas quadrículas avaliadas com grau de invasão 0 ou 1 (sem risco iminente ou com risco iminente de invasão mas sem evidência da presença de espécies exóticas invasoras no momento da observação) considerou-se que a área invadida era de 0 metros quadrados. Nas quadrículas com grau de invasão 2 considerou-se que a área mínima seria de 0,1 metros quadrados (por exemplo uma acácia isolada ocupando a área de um quadrado com 32 cm de lado). As restantes áreas mínimas e as áreas máximas foram calculadas tendo em conta as percentagens mínimas e máximas de área invadida nos vários níveis, de acordo com a escala adotada. No final foram adicionadas as áreas assim obtidas. Eis os resultados:
  • quadrículas com grau de invasão 2 (até 0,04%): área total invadida compreendida entre 0,0002 ha e 0,0075 ha;
  • grau de invasão 2 a 3 (até 0,2%): área total invadida entre 0,011 ha e 0,062 ha;
  • 2-4 (até 1%): 0,077 a 0,39 hectares;
  • 2-5 (até 5%): 0,43 a 2,1 hectares;
  • 2-6 (até 25%): 2,0 a 9,9 hectares;
  • 2-7 (até 75%): 14 a 49 hectares;
  • 2-8 (até 97%): 30 a 68 hectares;
  • 2-9 (área total invadida): 42 a 81 hectares.
Note-se que estes valores não representam a área de um polígono envolvendo aquelas quadrículas: representam a área efetivamente ocupada pelas espécies exóticas invasoras (maioritariamente acácias), ou seja, a área de uma mancha única com densidade máxima reunindo todas as plantas de espécies exóticas invasoras observadas na Mata do Sobral. De acordo com a informação de que dispomos a área total abrangida pelo projeto atualmente em execução (com financiamento POSEUR) é de 35 + 75 = 110 hectares, mas este valor provavelmente corresponde à área de um polígono ou pequeno número de polígonos envolvendo as principais manchas de espécies exóticas invasoras (polígonos que provavelmente também incluem algumas pequenas áreas não invadidas ou com menor densidade de invasão, demasiado pequenas e numerosas para terem sido excluídas). Em todo o caso os valores obtidos (42, 81 ou 110 hectares) são da mesma ordem de grandeza. Admitamos o melhor cenário possível: a área total efetivamente ocupada pelas espécies invasoras folhosas (acácias, eucaliptos e háquea-folha-de-salgueiro) é de "apenas" 42 hectares em toda a parte da Mata do Sobral inserida na Rede Natura 2000. O valor total disponível para o projeto POSEUR em execução é de 392500 euros, o que corresponde a cerca de 9300 euros por hectare. No pior cenário, se a área total efetivamente invadida for de 81 hectares, o valor disponível será de 4800€/ha aproximadamente. Nem todo este dinheiro terá sido destinado às ações de remoção de flora exótica invasora (o projeto também contemplava outras medidas de valorização do local, por exemplo a criação de um circuito de GeoCaching), por isso deverá admitir-se que apenas estariam disponíveis cerca de 4000 a 8000 euros por hectare efetivamente invadido por acácias ou outras espécies exóticas. No entanto, já vimos que o custo da remoção de acácias (ou eucaliptos ou outras folhosas invasoras) através de corte e pincelagem com herbicida rondará os 20000 euros por hectare. Comparando estes valores (estimativas sujeitas a alguma incerteza) conclui-se que possivelmente os recursos disponibilizados para este projeto não seriam suficientes para uma correta aplicação da técnica de corte e pincelagem em toda a área invadida na Mata do Sobral.
  • CONSEQUÊNCIA: adulteração dos métodos de controlo e consequente perda de eficácia
Quem visitou a Mata do Sobral repetidamente ao longo dos últimos meses terá constatado que a técnica de corte e pincelagem não foi corretamente aplicada:
  • O aspeto geral das áreas onde foi realizado o corte (área de intervenção com contornos irregulares, árvores tombadas ou parcialmente derrubadas na orla da área de intervenção) indiciava que o corte estaria a ser realizado exatamente como se não houvesse lugar à pincelagem.
  • Não eram visíveis equipas formadas por dois trabalhadores (um a cortar e outro a pincelar com herbicida).
  • Muitos dos cortes eram irregulares (aparentemente realizados com motorroçadora e não com motosserra), incompatíveis com a técnica de corte e pincelagem.
  • Houve rebentação massiva (nas áreas onde as acácias foram cortadas em abril de 2021, praticamente todas as toiças apresentavam numerosos rebentos em julho de 2021), mais um indício de que a técnica de corte e pincelagem não foi aplicada corretamente.
  • Três meses após o corte os rebentos já atingiam cerca de 1 metro de altura (possivelmente mais), o que não se esperaria caso a técnica de corte e pincelagem tivesse sido aplicada corretamente.
  • Em julho de 2021 alguns destes rebentos mostravam sinais de uma aplicação recente de herbicida mediante pulverização quando o correto teria sido realizar novo corte e pincelagem na zona do corte.
  • No final de julho de 2021 um grupo de voluntários visitou a Mata do Sobral e cruzou-se com um trabalhador que transportava um trator com um reservatório de herbicida para pulverização e não para pincelagem.
Existem muitos indícios de que a aplicação de herbicida não foi efetuada de forma localizada através de pincelagem mas sim através de pulverização. Provavelmente o herbicida também não terá sido aplicado imediatamente após o corte mas sim vários minutos ou mesmo várias horas após o corte. Compreende-se que assim tenha sido: cortando um grande número de árvores de uma só vez e aplicando depois o herbicida conseguir-se-ia atuar numa área maior com os mesmos recursos humanos - uma necessidade face à insuficiência de meios disponíveis, como vimos acima. No entanto, esta alteração ao método de controlo reduz drasticamente a sua eficácia, como se tem visto no terreno. Corre-se o risco de que o único resultado prático desta intervenção seja atrasar a floração das acácias, ganhando algum tempo (cerca de 4 anos) - mas para isso bastaria cortá-las, dispensando a aplicação de herbicida, poupando assim algum dinheiro e evitando a contaminação dos aquíferos e a destruição de flora autóctone em resultado dessa aplicação.
  • O QUE DEVERIA TER SIDO FEITO na Mata do Sobral?
  • Idealmente a entidade gestora da Mata do Sobral - ICNF - deveria ter detetado e eliminado atempadamente todos os focos de invasão por espécies exóticas, pelo menos desde que se começou a ter consciência para este problema há pelo menos duas décadas (desde a trágica invasão das dunas de São Jacinto pela acácia-de-espigas, por exemplo). É revoltante encontrar na Mata do Sobral numerosas manchas de nível 4 (área invadida entre 20 e 100 metros quadrados) causadas por uma única árvore adulta existente antes do incêndio de 2017. De acordo com as estimativas já aqui apresentadas a eliminação de uma mancha dessa dimensão através de corte e pincelagem poderá exigir até 14 pessoas.hora, enquanto a eliminação da acácia mãe (por exemplo através de descasque) poderia ter sido feita por uma única pessoa em menos de 10 minutos: a ausência de uma intervenção atempada por parte dos serviços florestais multiplicou por 80 o trabalho necessário para a eliminação desse foco de invasão.
  • Antes do incêndio de 2017, quando foi elaborado o primeiro projeto para intervenção nesta área, deveria ter sido realizada uma avaliação mais rigorosa da eficiência de cada técnica e dos recursos necessários para a sua aplicação em toda a área do projeto. Aparentemente terá havido um sub-financiamento deste projeto, talvez em resultado de um excessivo otimismo acerca da eficiência das técnicas preconizadas.
  • Após o incêndio de 2017, quando as acácias adultas morreram e começou a germinação em massa, dever-se-ia ter mobilizado todos os recursos disponíveis (incluindo a mobilização de voluntários) para uma intervenção rápida. O arranque das jovens acácias em terreno sem mato, logo nos primeiros meses após o incêndio, teria sido extremamente rápido. É lamentável que tenha havido um segredo quase total acerca deste projeto durante quase dois anos, até um momento em que as acácias já eram muito mais difíceis de arrancar - quer pelo tamanho dos seus caules e raízes quer pela densidade de mato em redor.
  • Não tendo havido uma atuação rápida em toda a área, dever-se-ia ter canalizado os recursos disponíveis para algumas áreas (preferencialmente contíguas) com nível de invasão menor. Se os 392500 euros disponíveis para este projeto apenas permitem a realização de corte e pincelagem em cerca de 20 hectares (admitindo um custo de 20000€/ha), se a área total ocupada pelas "quadrículas" com nível de invasão inferior ou igual a 6 (até 25%) não excede os 10 hectares, se essas 178 "quadrículas" representam quase 70% da área da Mata do Sobral inserida na Rede Natura 2000 e concentram a maioria das espécies presentes na Mata, então dever-se-ia ter começado por intervir nessas áreas menos invadidas e não nas áreas mais densamente invadidas.
    Nas zonas com densidade de jovens acácias superior a 25% seria preferível proceder a desbaste no interior (deixando por exemplo 1 acácia por metro quadrado para ensombramento) atuando apenas na orla (por exemplo através de arranque) para impedir a expansão da mancha. Mais tarde, quando as acácias não cortadas atingissem a maturidade e antes que começassem a contribuir significativamente para a reposição do banco de sementes, proceder-se-ia ao controlo dessas acácias através de descasque ou mesmo corte e pincelagem (muito mais eficiente nesse momento pois o número de árvores para corte e pincelagem seria muito menor).

  • QUE LIÇÕES devemos retirar para o futuro?
  • Precisamos de recolher, sistematizar e divulgar mais informação quantitativa sobre a eficiência de cada um dos métodos de controlo: os projetos atualmente em execução fornecem excelentes oportunidades para esta recolha de informação.
  • Precisamos de otimizar algumas técnicas (por exemplo o corte recorrente: saber qual o mês ou quais as condições meteorológicas ideais para o corte inicial, saber qual o intervalo de tempo ideal entre os sucessivos cortes de rebentos, etc.).
  • Precisamos de testar novas técnicas (por exemplo o corte parcial e descasque: cortar a árvore a cerca de um metro do solo - de modo a impedir ou reduzir drasticamente a produção de sementes - e efetuar o descasque apenas num anel junto ao solo, deixando que a planta rebente acima desse anel de modo a esgotar os recursos disponíveis na raiz).
  • Precisamos de calcular os recursos que cada uma das técnicas iria exigir, tendo em conta a área e as caraterísticas da zona onde se pretende atuar, escolhendo a técnica que exija menos recursos (ou - em caso de empate - aquela cujos custos e resultados são mais previsíveis e menos sujeitos a flutuações).
  • Precisamos de fazer esta avaliação a uma escala mais micro - em parcelas com apenas alguns hectares ou ainda menores - podendo até escolher-se técnicas diferentes para locais diferentes no âmbito do mesmo projeto.
  • Precisamos de disponibilizar recursos suficientes para cada intervenção, em vez de cairmos num otimismo que conduza a um sub-financiamento dos projetos.
  • Precisamos de mobilizar os recursos endógenos de cada região sem desprezarmos nenhum deles: pequenos proprietários florestais, cidadãos voluntários, escolas, associações, empresas, etc.. Muitas pessoas e entidades têm tempo e outros recursos disponíveis para a defesa da floresta autóctone contra o avanço da flora invasora, simplesmente não estão sensibilizadas para a importância dessa tarefa.
  • Na impossibilidade de atuar em grandes áreas com os recursos disponíveis, precisamos de definir objetivos que sejam realmente exequíveis (privilegiando áreas com maior valor natural e paisagístico) e cumprir os projetos com todo o rigor para obtermos resultados duradouros.
  • Precisamos de privilegiar a atuação precoce nos locais onde a invasão ainda se encontra em fase inicial, conscientes de que a falta de uma intervenção precoce poderá obrigar a uma despesa 100 vezes maior em menos de duas décadas.

The first of many: Blushing Bride Bioblitz - weekend 2 or 3 October 2021!

I am super excited to announce the 1st of many: Blushing Bride Bioblitz, taking place on the weekend of the 2nd/3rd of October 2021. The final date will be announced closer to the time, depending on the weather.

The aim of this Bioblitz is to get the Franschhoek and Stellenbosch communities, and everyone else who is keen, to record as many species, alien and indigenous, as possible, in Assegaaiboskloof in the upper Berg River, the home of the last wild population of the well known and loved Blushing Bride, Serruria Florida. We really want to ignite hearts, souls and minds to this incredible gem in our midst, so that it can be re-appreciated and loved and ownership taken thereof in order to protect and restore its home.

We sit at a spectacular juncture in time... let me take you one step back.. we started planning this bioblitz in December 2020, it would have been part of a beautiful programme of talks and training sessions in Woordfees, the annual cultural festival in Stellenbosch, in September 2021, coinciding with the flowering time of the Blushing Brides. After all had been planned, specialists committed, excited and lined up,... a devastating fire scorged the whole of Assegaaiboskloof and Jonkershoek valleys in Feb 2021, razing the home of the blushing brides to the ground...... then followed more covid-related waves and lockdowns... and Woordfees changed its format so that it was unfortunately not possible any longer to host our programme there... back to the drawing board it was.. !!

The Feb 21 fire broke my heart in two... I am a visual and tactile person, and seeing and being in fynbos has become my reason for being.. yes, I know now that fynbos needs fire, but over the years, Assegaaiboskloof has become a sanctuary to me, an escape into paradise.. and when smoke billowed across the Boland for 8 days, and I saw paradise going up in flames, I won't deny it, I was devastated.

... it took some persuasion ( I won't mention names) about new life, bulbs and orchids to be discovered .. to take me back into the valley 3 weeks ago, just to realize that paradise is not lost! Quite the opposite. Fynbos has evolved and has survived with fire for millenia past and will continue doing so for millenia to come... I witnessed first hand with my own eyes how the skeletal frames of widdringtonia nodiflora are sending out new shoots, how baboon have returned, buck spoor... fan aloes, blackened by the fire but very much alive, are in flower en masse, reseeding proteas, the skeletons in tact all over the hills, not destroyed but presenting perfect seeds on outstretched arms... but also canary island pines resprouting and already at knee hight.. hakea.. wattle...

...which brings me back to this spectacular juncture, opportunity in our midst.. from now on, year on year on year after Feb 21, we have the opportunity to map out growth and life and regeneration of this unique patch of fynbos. Now is our moment to really get to know it intimately. And it will not disappoint.. AND in parallel, we have to note and take action against invasive aliens in the midst, from the ground up, not stopping, until all is eradicated... (hack is planned for Nov 21.. watch this space)

2 or 3 Oct 2021 is when the 1st of many Blushing Bride Bioblitzs' is happening. Let me know via inbox message if you would like to join, please add e-mail address and cell nr. Numbers are limited and participation will be on a first come first served basis. (I will try my utmost to accommodate everybody! I promise)

Take care, look after yourselves,
Santie

In the Sibelius Forest

The Sibelius Forest (Sibeliuksen mestä) is outside Hämeenlinna, the Finnish town where the composer Sibelius grew up. A nature trail follows places where he liked to walk in his youth and was inspired to compose pieces such as Finlandia, which gave the Finns their memorable national anthem. The climax of the walk comes at the top where a rocky outcrop gives a spectacular view onto Lake Aulanko far below. A family of black-throated divers could be seen on the lake and woodpeckers could be heard drumming. Pine trees held crested tits and some shy passerines which remained unidentified. Another rich habitat is along the lakeshore near the car park, where birds included a Lesser Whitethroat and a Tree Pipit.

ArMi's First War: black swallow-wort at Hill's Hill

The Arlington MA Invasives 'ArMI' has taken on some challenging projects in the past month, including battling a big oriental bittersweet plant (https://www.inaturalist.org/observations/85030546) and some patches of black swallow-wort (BSW), but we have a much more ambitious goal right now; we found an entire grove in Hill's Hill which has been taken over by BSW (https://www.inaturalist.org/observations/84479644). We are going to beat back that nasty invasion, and eventually destroy it. The plan is as follows:

PLAN: We are going to start by cutting and bagging the plants so the seed pods won't burst and spread.

  • cut the stems a few inches from the ground, without disturbing the roots, as that encourages new root growth
  • strip any leaves left on the plant to help starve it of carbohydrates
  • clear the entire patch in this manner, making sure to gather all the seed pods for disposal
    When this is done, we will go after the roots. We will be taking the territory back by clearing every root from the areas where we dig, so that we aren't just providing tilled soil in which it will regrow. That is slow going, but a war isn't won in a day, and as long as we keep it from going to seed we will win in the long run.

EVENT: I will be at Hill's Hill from 7-10am on Sunday, 8/8, to work on bagging plants. I have been reaching out to friends and local clubs, but you nature-lovers are my real hope for recruiting. I'm not asking you to be up by 6 on a Sunday if that's not your thing; join when you like, and make sure to bring your gloves and clippers (I have a few spares), and wear bug spray. You can park by the soccer field off Summer street (88 Summer St, Arlington -- take a left as you enter the parking lot) and head into the woods, keeping to the trails near Summer St (when in doubt, take the trail on your left). It is a small park, but the GPS coordinates from this observation on iNaturalist might help: https://www.inaturalist.org/observations/87802201. You can see Summer St. in the background of the last picture.

To make this event more fun I am bringing a portable speaker (we can democratically pick the Spotify station), and we are going to brunch afterward. We will be stopping promptly at 10am, and heading to Thrive Juice Cafe at 10:30. I am a huge fan of their breakfast sandwich.

Solo efforts: Feel free to work on this on your own! Feel free to message me for details on how to get bags of weeds removed if you bag more than you can handle. If you do work on this patch, please post an observation with a before and after picture, because we would love to see your work.

For a detailed update on our latest projects, see the Hill's Hill newsletter.

Sensitive species.: HOW TO DEAL WITH.

Sensitive Species 2021

iNaturalist has updated its security features around obscured data. This makes is much more difficult to access locality data for these observations.
But you also need to do your bit to help keep data secure:

  1. Be aware of the order that you add your data onto iNaturalist:
    • On the upload tool, add sensitive species in a separate batch to common species
    • In the field allocate sensitive species to a recorder and let other users add the ordinary species.

  2. Beware of any notes or comments that expose details of locality, or sequence of observations.
    • Put all the locality information in the Location Notes: they will be obscured there and available to those you trust

  3. Keep habitat and habit shots tight so that photos don’t reveal the locality.
    • Use more common species for your spectacular scenery shots.

  4. Be careful of tabs, and special fields that you add to your photo exif data.
    • iNat obscures locality and time information in the exif, but cannot deal with special fields and tabs.
    These additional precautions will help keep Sensitive Species safe.

Q? Can I have a list of Sensitive Species so I can take special precautions? (such as uploading separate lists)
!A The list of Sensitive Species is sensitive too. Use your common sense. Collectors want things that are
very rare,
old - or take a long time to grow,
are not easy to mass produce by seeds or cuttings,
that are easy to smuggle or transport, and
can be stored for some time.

Bulbs and succulents are top contenders.
If a species is not on the Sensitive Species list (i.e. iNaturalist does not automatically obscure it) and you feel strongly that it should be, please contact your CREW officer. Likewise, if you feel a species that is obscured, should not be, please tell us.
Note that the iNaturalist obscuration is very effective. Dont worry about the odd observation slipping through your guard: iNaturalist will catch these.

If felid eyespots lead offspring, why are they already present at birth?

As I mentioned in my latest Post, it is sometimes suggested that the eyespots on the back-of-ear of felids have evolved to help the mother to lead her infants. However, a glance at https://natureslens.co.uk/2018/05/bengal-tigers-of-tadoba/ and https://www.dreamstime.com/stock-photo-tiger-mom-three-cubs-mother-carrying-food-following-image76672676 should cast doubt on this idea.

The colouration of most species of felids is precocial, with most of the markings already present at birth. This includes the back-of-ear pattern.

It seems that in all felid species possessing a back-of-ear pattern, the pattern occurs in infants as well as in adults. Furthermore, the pattern is always, as far as I know, as clear in adult males as in females, despite the fact that felid fathers never lead infants.

Of course, it remains possible that the back-of-ear patterns of felids - like most features of organisms generally - combine several adaptive values. However, would it be safe to say that leading offspring is not one of them?

Observation of the week – July 24-30, 2021

Our twelfth observation of the week is the distinctively coloured Milbert’s Tortoiseshell seen by Bev (@bevlynn99).

Milbert’s Tortoiseshell is a quick and active species that seems to rapidly dance about in its environment. You might catch it resting on the ground or a tree with its wings spread flat – as seen in Bev’s lovely photo.

The upper sides of Milbert’s Tortoiseshell wings look nothing like any of our other butterfly species, and it is always a pleasant surprise to find. Bev says: “I'm an avid wildlife photographer so I take pictures of pretty much everything I see while out on the trails. I was excited to see this one as it was different from what I have seen so far this year.

Young Milbert’s Tortoiseshell caterpillars live in communal nests on their host plants – which mainly includes nettles (Urtica spp.). This bunch of hungry caterpillars can completely consume their host plant’s leaves, leaving little behind. As adults they feed on sap and animal dung as well as nectar from flowers like Joe-pye weed and Black-eyed Susan.

Milbert’s Tortoiseshell is one of several native butterfly species that have benefited from learning to use a non-native plant as a host. European Stinging Nettle (Urtica dioica ssp. dioica) was introduced into North America by early European settlers, and has become much more common than the native Slender Stinging Nettle (Urtica dioica ssp. gracilis). Forest clearing and road building allowed for the spread of the non-native nettles, and Milbert’s Tortoiseshell took advantage of the abundant new food plant.

Unlike this historical increase in their populations, it is thought that Milbert’s Tortoiseshell is currently becoming less common in the Great Lakes area. One thing that you can do to support them is to let their nettle host plants grow. Although they are prickly and unpleasant to touch, we can appreciate nettles from afar for the home that they provide to Milbert’s Tortoiseshell – as well as other butterfly species like the Red Admiral, Question Mark and Eastern Comma.

Veld burning in Bonamanzi

In Bonamanzi fire is used as a management tool in the savanna and woodland habitats. The principle guiding this is that the grasslands in Zululand were formed under a fire regime and need fire for their continued well-being.

In the Bonamanzi Game Reserve there has, in recent decades, been a large increase in woody plants within these grassy habitats. One of the main drivers of woody plant increase is too little burning – where the fires are not frequent enough and not hot enough. So, as well as rejuvenating the grasslands, fire is used to reduce the woody plants – in conjunction with mechanical clearing.

The aim is to have a patchwork of grassland where there are sections with different burn histories. This promotes what is known as a ‘fire mosaic’ which provides a range of ‘micro-habitats’ which support a high diversity of plant and animal species.

The wetlands are also burnt – but at less frequent intervals than the grasslands. Fire is excluded from the riparian and sand forest habitats.

Most of the burning in Bonamanzi is done in late winter when there are high fuel loads and there is not yet a spring growth flush.

La importancia de los huertos para polinizadores como estrategia de consciencia ambiental

En la actualidad, el hombre se a creado un falso concepto de como tratar a las demás especies de este planeta, desde los animales mas grandes hasta los mas pequeños ! Pero claro esta que nada cambiara en los próximos años, es despreciable escuchar a alguien que habla del mundo como si fuéramos seres inmortales, a este mundo le hace falta mas pandemias y muchas plagas ( y creo que ni eso podría cambiar la forma de pensar de las masas)

Debido a la gran perdida del ecosistema en las ANP’S del estado Guanajuato con las talas clandestinas, cacería furtiva e incendios forestales. Se propone salvar 1/3 de flora nativa

Basta de tener un pensamiento < economicosocialyambiental> Que de nada sirve a la naturaleza le funciona mas un ser humano consciente y es ahí donde todos y cada uno de nosotros debemos aprovechar a los pequeños porque de lo contrario podremos perder todo lo que conocemos

The 3rd 10 000 trees target reached

Our third 10 000 tree target has been reached in a little under 2 months, and thanks very much to all who contributed. For this round, a particular thanks to farmers in the Ladismith area for volunteering to sponsor some temporary workers to help join the effort. Their very welcome three-day contribution made a significant impact.

For the next 10 000 trees let’s not waste any time and get out there for some more socially-distanced fun and action!

Wahlenbergia

https://www.inaturalist.org/observations/69138022

WAHLENBERGIA NODOSA

Hi Evieb,
The info I have for W. nodosa is the below (I've bolded the bits I've found helpful in the past for IDs):

"
A rigid much branched diffuse or erect shrublet, up to 50 cm high though commonly 15—30 cm., the branches often divaricate, the younger branches white or pale-coloured.
Leaves alternate, (often) distant, reflexed, fasciculate, rather thick, ovate-lanceolate, 2—6 mm. long, 1 —1-5 mm. wide, acute, concave above, the edges entire or with minute teeth .

Inflorescence with rigid spreading branches, often spinous in the later phases.
Flowers solitary, 1 —5 to a branch, on slender pedicels 3—7 mm long.
Calyx lobes 2—3 mm. long, acute or mucronate.
Corolla white, fading to yellow, often brownish outside, 5—8 mm. long, the tube very short, the lobes glabrous. Bases of the filaments ovate to lozenge-shaped, densely ciliate.
Style blue, longer than the corolla, shortly hairy, gradually thickened to the top: stigma lobes 3, very short.
Ovary less than half inferior, the lower part rounded or flattened, less than 1 mm. long, about 1-5 mm. diam.
Fruit 5-ribbed, broader than long: valves as long as the calyx lobes, twice as long as the lower part.

The type is EcMon s.n. (Port Elizabeth) in herb. Bonder, (S).
Rocky places in rather dry regions, especially on hills in and around the karroo.
The commonest and most wide-spread species.
Rather variable in habit and in the branching of the inflorescence.
Distinguished by the small reflexed leaves, the branched inflorescence, and half superior ovary. The leaves on the main stem often fall, only the axillary fascicles persisting.
In the past much confused with L. tenella and L. diffusa, indeed Ecklon & Zeyher issued specimens under the latter name.

A butterfly and some life

We had this new parking structure since beginning of the year. And recently i start to see empty pupas everywhere on the pillar foot, and today... wow!

I didn't know she has such a bad English name, i don't like it to be honest. In China, we simply call her "yellow verge" (which i also don't really like).

It goes back to 2000 when I was brought to an rural area of our province by my parents. It was an autumn afternoon and we were sitting on the back truck of some motor vehicle going along a country road. Golden sunshine through the woody surroundings, ,,, and,,, then ,,,, this beauty "yellow verge" just fly across the road that we have just passed, and disappeared on the other side of the wood, 5s. Short enough if you are not a nature fan, but long enough to stun a boy who has 3 years old being a collector.

I don't know how to describe the feeling, she was just went immediately to the top experience of sublimity so that the shock is hardly speaking of a collector but sort of life education and world view. How could something being so beautiful?

2000, that's the year I went for three insect collection trips, after the first in Shandong and second in Zhangjiajie in 2000 summer, and this one. It's even a banquet for a professional collector. Since i started being a nature fan, my parents had taken every of their chances to take me around when they have a meeting or conference somewhere else. My grandparents, too, they capture bugs when they are in the long line in front of restaurant or even in the bathroom....... When I am looking at any of my old collections, these are all things that come to my mind.

Let alone the old childhood smells, kitchen and garden, face and voice of relatives, and how they have been doing till nowaday. These are the things that slowly rising to my mind, light as a piece of nocturne but mellow like evening ocean tide.

I know people here love nature for different reasons, and whatever creature you like and liked, fit into different places of your life cabinet. Some people start young but end early, some start late but continue to death. Some for money, some for showing off, some for hobby and company. For me, though scientist life now has stressed and tortured me who started off dreaming as being a pure collector for a life, I have seen these lovely insects and plants as not only a hobby that kill plethora time of a dull adult, but a nearly intangible relaxation goes deepest to resonate the blood, and even more, a toast to old time and beloved old friends, forever.

That autumn, at the end of trip, we finally got one sample of "yellow verge" taken by my dad, only one. Skip all the excitement. It is so intact that I didn't even try to shape it into the standard posture, for the fear of possible lesion. (We didn't have soften equipment before fixing it into shape back from trip) Five years later, during a check and cleaning, one of antenna was stuck off accidently and later on being glued on. (We lost a lot of specimen that sad year) Add another five years, I became a freshman of bio major. And then, somewhere in time, when people just keep moving on and lose track of time, my grandma said goodbye forever, and their old apartment garden abandoned, and I have been not living at home for more than a decade.... So many things and so little imprint...

Now on the pacific coast, drinking besides a yellow nightlamp, I believe my only specimen of "yellow verge" is still sitting in the hometown box somewhere in dark, soundly.

Counties Needing Observations: WA -- Okanogan, Ferry, Benton, Columbia -- OR -- Wasco, Gilliam, Sherman, Morrow, Jefferson, Baker, Lake

News and What to Expect in August:
In the first month of this project, we've got 152 observations which if I have my math current, will make us cut really close to our stats from last year. I know we can do better, especially myself. In the coming days, we will see just about the same things as July but we should be able to get something like Merlin or Sharp-shinned Hawks.

Observation of the week goes to datadan for his photo of a male Swainson's Hawk in Malheur NWR. I can't help but love Swainson's Hawks and I've noticed that the state typically doesn't get these lighter individuals. A majority of these hawks are intermediate or dark morphs west of the Rockies, though I'm not sure why that it is. Anyway, you can see the photo here:

Observation of the month goes to @seymoregulls for photographing a Great Gray Owl besides a lake. These large owls can be found in a majority of open forests in Washington and Oregon. They typically perch high in pine trees whilst looking over green meadows and when they spot their prey, they pounced just like this owl right here:

The Wind Rises

The Wind Rises
Monday, June 21st, 2021
22 Celsius
North Vancouver, BC
(Carson Graham Park)

The wind rises. The wind rises and the clear morning with it. The sky draws a beautiful sandy landscape, the sun still holds its breath before the lights of dawn. For more than a moment, time is away, the landscape freezes itself with the cold flicker of a bee’s wings.

Delicate tiny being, yellow with sunshine, flutters between the intricate patterns of colors that the blossoms have arranged. The wild blackberry’s stems and thorns, the flicker of her wings carries a golden currency, as if the weight of the world is swaying between a bee’s legs.

She jumps her way between Persephone’s daughters, recalling the golden days where she used to walk among them. A forgotten dryad.

Little the buttercups and dandelions know about her, and yet she is forever welcome. They open their scanty petals and carry her through the warm freshness of the day. Like bells, these petals howl to the path of the wind, shouting away the treasure of its pistils.

Now, days are golden too, but have turned grayer and distant, as Eolo’s tune whispers one hundred years of solitude, spreading nostalgic dreams in silent loudness.

The Sun reaches its zenith, and the wind’s music halts. Harmony is played in the strings of a new rhythm; the day is going and going and here I lie, still. Lately, I have felt uneasy with the idea that time is finally catching up with me. But not here, not now. I am seated beside a pinus tree which I hope has seen better days. I am once again reminded of the innate beauty and complexity that lies in a single tree. Its needles are not perfect, and they don’t need to be. I try to guess its height. At least 8 meters I decide. Trees evaporate 95% of their water through nanoscale-pores, creating immense negative pressures of 10’s of ATM, and although water should be boiling, the xylem tubes which carry it can never contain air bubbles, preventing water from reaching the necessary activation energy; all this, just to absorb a couple of carbon molecules. The same carbon that closes them, you see.

I can’t but feel humbled and overwhelmed by the ubiquitous beauty that exists and surrounds me. I feel grateful, and hopeful. Maybe the perfect world is not one we need to seek.

The wind, the wind rises, and the yellow bee awakes. The sun has painted the sky blue, colors hang as watercolor garlands. A farewell is, as the clock’s hands have decided that time it is. With the voice of the last sunlight, the bee’s wings follow Apollo’s call, flying their way to a new dawn.

Saw My Elusive Favorite Plant

On July the 31st, 2021: I saw Monotropa uniflora in the wild, not but 500ft from my house; one patch was flowering, the other now has seed pods. Very beautiful!
