Summary
The Curly Sedge Carex tasmanica is a small, perennial, clumping sedge endemic to Victoria and Tasmania, growing in seasonally damp sites in grassland or grassy woodland. The species is currently known from about 60 sites and perhaps 500,000 or more plants. However, most plants occur in just two populations, with the remainder generally small and isolated. Much of its habitat has been converted to agriculture, and other populations have been lost to industrial and urban development. Major threats include heavy grazing, weed invasion, land use change and climate change. The Curly Sedge is listed as Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. This national Recovery Plan for the Curly Sedgeis the first recovery plan for the species, and details the species' distribution and biology, conservation status and threats, and recovery objectives and actions necessary to ensure its long-term survival.
Note:
The Curly Sedge is no longer considered threatened in Tasmania (S. Bryant, DPIW Tas pers. comm.). It was previously listed as Vulnerable under State legislation, but numerous populations have been discovered since the early 1990s. A subsequent assessment concluded that the Curly Sedge did not warrant listing as Vulnerable or Rare under Tasmanian legislation, and the species was subsequently removed from the schedules of the Tasmanian Threatened Species Protection Act 1995. As such, Tasmanian authorities do not consider there is justification to participate in a national recovery program for the Curly Sedge. Therefore, recovery actions in this plan refer to Victoria only.
