On the 22nd of July a small group of orchid conservationists planted the Stuart Mill spider orchid (Caladenia cretacea) back into the John Colahan Griffin reserve in Victoria.

It was a spectacular day for planting 32 baby orchids to complement the 12 specimens already recorded on the reserve. After rain the night before to soften the earth, the sun was shining and insects active.

The seeds and fungi used were sourced from a nearby property and taken to the Australian Native Plant Conservation (ANPC), Orchid Conservation Facility in Horsham. Here Dr Nouska Reiter used her amazing laboratory skills and commitment to endangered orchids to propagate new plants from seed.

The seedlings were put in within a fenced area for protection. Connectivity for pollinators has been lost between the source site and our reserve but these new plants should increase the genetic diversity of the small Stuart Mill spider orchid population on John Colahan Griffin​.

This work will also contribute to long-term research into preferred planting methods to optimise pollination rates.
