[email protected] (corresponding author) Abstract latter are important reservoirs of ectomycorrhizal fungal diversity, and that they may be expected The macrofungi of an aggregated retention to show an increased species richness at a later coupe harvested and burnt in April 2004 stage of regeneration of the surrounding forest. at the Warra long-term ecological research (LTER) site were documented at approximately fortnightly intervals over a period of 16 months Introduction between February 2005 and June 2006. In transects of approximately 400 m total length, The Warra silvicultural systems trial was 167 macrofungal species were recorded in established as a means of assessing a range the unharvested aggregates compared to 125 of alternatives to clearfell, burn and sow species in the regenerating harvested area, with (CBS) in Tasmania’s lowland wet eucalypt 63 species common to both. The regenerating forest (Hickey et al. 2001). Ecological area was a source of many saprotrophic fungi assessments have been based on long- and also contained many species that are term monitoring of the responses to these characteristically opportunistic, appearing after treatments of vascular plants, non-vascular disturbance or fire but not generally seen in plants (Kantvilas and Jarman 2004), birds forests that have progressed beyond the earliest (Lefort and Grove 2009) and litter-dwelling stage of regeneration.
