Minister's Reasons for Recovery Plan decision

A recovery plan for the windswept spider-orchid (including other Tasmanian orchids) is in place, therefore there is no change to the Minister's initial recovery plan decision (to have a recovery plan).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
