The sedges, Carex tasmanica and Schoenus absconditus, were considered to be threatened species at the national level. They are species of grassland and grassy woodland in the driest parts of Tasmania, C. tasmanicabeing associated with drainafe lines, and S. absconditus characteristically occurring in Themeda triandra grassland, in situations where there is a large amount of intertussock space. Both species proved much more common than previously thought, and both species have been downlisted. They are both well-adapted to mechanical disturbance and sheep grazing. C. tasmanica is also herbicide resistant. However, mowing and cattle grazing deleteriously affect C. tasmanica. S. absconditus can no longer be regarded as a rare or threatened species. However, C. tasmanica has disappeared from two localities out of 30 in the past four years and has no substantial populations in any secure reserve. Secure reservation is needed for this vulnerable species.
