Arachnids were sampled by pitfall trapping in 2 areas of karri forest on both ridge and creek sites. One area was sampled in spring and early summer for 4 years during which it was cleared, burnt and replanted with karri. The other site, sampled for 2 years, was mature karri forest. Five orders of Arachnida, including 18 families of Araneae, were represented. Clearing and burning resulted in more aggregated captures and in marked changes in the structures of the arachnid community. There were changes in species dominance and a proportional increase in the number of individuals at creek sites. Species richness recovered from the forestry management practices more slowly on the creek sites than on the ridge sites.
