Summary iii Biodiversity of Wielangta Forest The following report reviews the biological conservation values of Wielangta Forest and maps forest of high conservation significance. A new reserve system for Wielangta is proposed that better captures the biodiversity values thus ensuring their long term conservation. Flora Fauna • Highly diverse, the Wielangta area has been identified as a centre for flora endemism, containing 30% of all Tasmanian flora species. • Twenty six threatened plant species are identified along with several that are highly significant including some of biogeographical importance. Wielangta is likely to provide an important refuge, securing habitat in the event of climate change. • The recently discovered Wielangta bird orchid is a species new to science, and is awaiting formal description. • Previous assessments have identified 11 floristic communities as having the highest conservation significance. • The area is biogeographically significant for many other plant species not listed as threatened. • Eucalypt species richness is unusually high and includes at least 18 species, with several rare and isolated occurrences. • Relict rainforest and mixed forest communities in Wielangta are identified as extremely important biogeographically, susceptible to harvesting, and not accurately identified under previous mapping practices. • At least 8 threatened fauna occur in Wielangta. Four species are listed as nationally endangered, including the swift parrot, which is now nominated for up listing under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBCA) as critically endangered. • Wielangta provides the core range (almost 50% of habitat) for the broad toothed stag beetle. Nearly all this habitat is located within provisional logging coupes. • The study area supports a relatively high density of Tasmanian wedge tailed eagle nests, with ideal nesting and foraging habitat. • Wielangta is recognised as the heart of the largest Swift Parrot Important Breeding Area (SPIBA). The Wielangta SPIBA provides the greatest known area of nesting habitat adjacent to foraging habitat. The report identifies significant areas of unreserved nesting and foraging habitat.
