  • Flowers are required for the identification and to aid detection of this ground orchid which dies back to subterranean tubers after flowering. The few confirmed observations of this species were made in December. Surveys should focus on open or disturbed areas, which the species appears to prefer.
  • Prasophyllum castaneum has been recorded from coastal areas on Bruny Island in damp shrubby and sedgy heath on sandy loam, on Mt Brown on the Tasman Peninsula in damp skeletal soil under the protection of rocks and tea-tree and banksia scrub dwarfed by continual exposure to strong sea winds, and in the Ellarwey Valley near Cape Pillar in recently burnt windswept coastal heath/scrub on skeletal rocky soils.

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. ​​​​​
