Prasophyllum olidum is a terrestrial orchid endemic to Tasmania’s Northern Midlands. It is known from a single site at Campbell Town golf course, where it grows in the native grassland ‘roughs’. The total population in any given year consists of fewer than 200 plants in an area of just 60 by 40 m. The species is at risk from inappropriate management activities (timing and extent of slashing) and weed invasion, with a high risk of local extinction due to the population’s small size.

A complete species management profile is not currently available for this species. Check for further information on this page and any relevant Activity Advice.

  • Flowers are required for the identification and to aid detection of this ground orchid which dies back to subterranean tubers after flowering. Flowering is in late November, extending to early December. Unlike many leek-orchids, Prasophyllum olidum flowers freely in the absence of fire.
  • Prasophyllum olidum is known only from the native grassland ‘roughs’ at Campbell Town Golf Course, where it occurs in relatively damp conditions on sandy loam.

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. ​​​​​
