​Prasophyllum amoenum (dainty leek-orchid) is a terrestrial orchid endemic to Tasmania. It is known from the State’s south at Snug Tiers and the Wellington Range, where it grows in sedgey moorland, subalpine sedgeland and bolster heath. The total population is thought to consist of fewer than 1000 plants, putting the species at risk from chance events, particularly for the smaller subpopulations. The main threats to the species are associated with climate change, including increased severity and frequency of drought, a possible reduction in snow and ice cover, and a possible increase in both fire frequency and intensity, the long-term consequence being a decline in the number of plants and reduction of suitable habitat.

  • Flowers are required for the identification and to aid detection of this mid-summer flowering ground orchid which dies back to subterranean tubers after flowering. Where the vegetation is not very open, surveys should focus on disturbed areas, as this species appears to like disturbance but not necessarily fire.
  • On Snug Tiers, Prasophyllum amoenum occurs in buttongrass moorland habitat on damp stony loam. On Mt Wellington, the species is found in and near cushion plants in alpine moorland.

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. ​​​​​
