Preliminary analyses! (1300+ observations! Now what?)

Hi everyone,

Thank you to all you amazing folks out there sharing your observations! More than 1300 observations have been shared by nearly 200 dedicated community scientists! Awesome.

The collective movement of this community is an incredible demonstration of the power of working together to accelerate research and foster shared understanding. Please pat yourself on the back :)

The observations shared in this project are invaluable for research and will be useful for identifying the factors affecting redcedar! We're thrilled to share we've been taking a deeper look into the data and are excited to see this effort translate into meaningful information for conserving redcedar.

The below (preliminary) data visualization shows how healthy and unhealthy trees group differently when plotted against a combination of environmental factors (soil, climate and topography). The next steps are to identify what factors are most important for whether trees are classified as healthy or unhealthy.

Learn more by attending one of our monthly research updates (https://foresthealth.org/research-updates/). Anyone is welcome!

Have you seen this fungus?

Have you seen this fungus on a western redcedar? If so, please indicate the tree has a fungus in the project question about 'other possible factors' and include a picture.

It is unclear if this fungus is cuasing any problems, but we've noticed it sporulating on a few trees recently. We suspect the fungus is a species of Coniophora, but more investigation is underway. Please keep an eye out!

Healthy Seasonal Foliage Browning

Hi everyone!

Please note we're entering the season where redcedar trees naturally shed their older needles. This happens annually and the tree is still healthy.

Do not be concerned if you see this natural drop of old needles in the fall. Please consider these trees 'healthy' when adding observations.

Celebrating 1000 observations!! (& project slightly simplified)

Hi everyone!

Woo! Time to celebrate!
1000+ observations is an epic feat!

These observations are helpful! They've given us a better understanding of the extent of the dieback issue and they will be useful to identifying important predictors for whether trees are healthy or unhealthy.

Keep up the great effort! Can we get to 2021 observations in 2021?

We've simplified the project questions a little to make adding observations a little easier. We made the 'percent of trees unhealthy' question optional and we dropped the question about tree canopy transparency after getting some helpful feedback. Thank you!

Special thanks to the top observers below!!!!!!
You all rock!

Feedback needed to improve UX of project

Hi everyone!

Wow, more than 900 amazing observations! Incredible. Soon we will begin taking a deeper look into the predictors for whether a tree is healthy/unhealthy.

Feedback needed
We need your input to improve the user experience of the project. What questions should we remove, reword or add? Please share your anonymous feedback at https://foresthealth.org/inat

Thank you all!!

Keep an eye out for possible heat related injuries - 'new tip death'

Hi everyone!

Amazing to see all the incredible observations from so many fantatstic indivduals. You all are redcedar champions.

Yesterday, Paul Hennon, retired USFS forest pathologist shared this photo of 'new growth tip death' from Portland, Oregon. He suspects it is related to the recent extreme heat events and wonders how wide spread it is. Have you seen it?


We've added an optional question about the heat damage, but please answer the symptoms question as you would have before the tree was damaged by heat.

Please keep an eye out! Thanks

New required question - feedback welcome!

Hi everyone,

We added a required question about the 'percentage of trees that are unhealthy' to get a better understanding of the severity of dieback at each site. Please let us know if that question is annoying or confusing!

Your feedback is important and we encourage you to help shape this project. How can it be improved?

As always, feel free to reach out to us with any feedback, questions or suggestions. You can get in touch by contacting us, messaging @jmhulbert, commenting below, or emailing foresthealthwatch@gmail.com.

Quality of observations - please include photos of cones or bloom

Hi Everyone,

There are a few species of 'cedar' in our region so it is important to include enough information to confirm that our observations are actually western redcedar.

Please include photos of the cones or the bloom (white powder) on the underside of of new leaflets when possible.

Redcedar cones

Redcedar have egg shaped cones that sit upright on branches.

Good examples of observations that include photos of cones have been shared by @geographerdave here and @angelique_k here .

Photo source: https://wildfoodsandmedicines.com/cedar/

Redcedar bloom

Bloom can usually be found on the underside of new foliage.

This OSU webpage and the photo below provide good examples of the differences in the bloom. Note the butterfly shaped bloom on the western redcedar. '

A really good example of an observation that includes a photo of the bloom has been shared by @whiteaeros here

Photo source: https://landscapeplants.oregonstate.edu/four-cedars-native-oregon

Thanks to everyone for sharing their observations.

Having these extra photos are especially helpful in cities where ornamental species such as port-orford cedar may be planted.

Note that it is still valuable and helpful to include your observations if you cannot get close up photos, but observations with these photos help ensure the data is high quality.
