The Metallic Sun Orchid (Thelymitra epipactoides) is federally endangered and all populations of this species have been experiencing population decline. Three populations of the Metallic Sun Orchid will be examined in differing habitats across the South West of Victoria. All of these populations are experiencing decline and considered a high priority for re-introduction. This project will initiate re-introductions of this species by:

• Investigating the edaphic conditions experience by these plants in the soil and local environment

• Identifying the identity and diversity of mycorrhiza associated with these plants both within and between populations

• Investigating the potential for tripartite relationships between the orchid, fungi and associated vegetation

• Investigating the optimal in-vitro germination conditions.
