Pimelea sp. Tunbridge (grassland riceflower) is a small shrub. In Tasmania the species is limited to the Northern Midlands where it grows in native grasslands and grassy woodlands on fertile substrates. Only three sites have been recorded in Tasmania, with fewer than 600 mature plants occupying about 0.2 ha in total, putting the species at high risk of local extinctions due to the small size of sites. Two of the sites have suffered recent declines due to habitat destruction. The species is at risk from land clearance, stock grazing, weed invasion, inappropriate roadside maintenance and a lack of disturbance. Known occurrences would benefit from weed control and the management of biomass levels.
