Chorizandra enodis (black bristlesedge) is a perennial sedge which in Tasmania is restricted to the George Town/Low Head area in the north of the State. It forms locally dense stands in low-lying swampy ground, including in remnant stands of Melaleuca ericifolia (coast paperbark) where it is most abundant on the fringes and in clearings, and slashed road-side verges and road-side drains. The species has a linear range of less than 8 km, and occupies an area of less than 1 ha, making it susceptible to chance events. Chorizandra enodis is unreserved, being restricted to private land used mainly for agricultural purposes, and road verges managed by the local council. It is known to persist under quite intensive land management practices, but is at risk from clearing for residential and industrial development and road improvements, intensification of agricultural activities including improving drainage and intensive stock grazing, frequent cleaning or deep scraping of roadside drains and competition from weeds.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
