Marlock, part 1

(writing in progress)

On the southern coastal plain of Western Australia there occurs an odd type of vegetation that deserves to be better-known. This is marlock low forest.

Marlock low forest is dominated by Eucalyptus, but in a form strange to most naturalists. This is because of the following combination:

  • the stand consists of trees, not the shrubby form of eucalypts called mallee,
  • it is as dense as the densest-known forests of eucalypts elsewhere, but only about 7 meters high,
  • there is minimal understorey,
  • the trees are as fire-prone as other eucalypts but their wildfire regime is restricted to the canopy because there is no understorey capable of carrying fire, and
  • the trees lack any basal burl and regenerate germinatively, not vegetatively.

To the naturalist familiar with mallee tall-shrublands or eucalypt open-forests, marlock low forest seems odd because it is dense, hardly taller than mallee, single-stemmed, and mortally affected by combustion of its crown..

On 7 February 1982 I visited woodland of Eucalyptus platypus, with a definite understorey of Acacia rostellifera, at Culham Inlet, just east of Fitzgerald River National Park. I observed Pachycephala occidentalis, Rhipidura albiscapa, Zosterops lateralis, and Smicrornis brevirostris, and heard Strepera versicolor. Sericornis frontalis was the common species in the undergrowth.
