Lichens of buttongrass (Gymnoschoenus) moorland in Tasmania

Abstract

Some 89 lichen species are recorded from buttongrass moorland. Hypocenomyce australis, Ochrolechia frigida, Placynthium nigrum, Protoblastenia rupestris, Siphulastrum triste and Trapeliopsis colensoi are new records for Tasmania. A preliminary classification of lichens in 12 broad moorland vegetation types is presented. Although most moorland lichen species are widespread in other Tasmanian vegetation formations, repeated, frequent fires are a major threat to their long-term survival within the moorland ecosystem. -from Authors
