Blechnum neohollandicum (prickly raspfern) is a terrestrial fern, known in Tasmania from a single near-coastal site in the State’s northeast. The species grows in damp shrubby eucalypt woodland on alluvial flats and adjacent slopes. The population consists of about 100 plants occupying 0.5 ha, the small size increasing its susceptibility to chance events. The main threats to the species are changes to hydrological processes exacerbated by upstream land clearance and climate change, browsing by native animals, and increasing frequency and severity of drought.
