The species is now listed as endangered under both the NSW TSC Act 1995 and the Commonwealth EPBC Act 1999. The recovery plan for this species calls for the establishment of an ex situ seed collection as an insurance strategy against loss due to catastrophic events.
In 2006 our Seed Collectors visited a small population in Mallanganee National Park on the north coast of New South Wales, one of only three populations, and collected seed from three mature plants. Part of the seed collection was stored in the Seedbank, part was used in a research project on seed viability and storage at Mount Annan and the rest was sown.
The resultant 40 plants from this sowing were planted in Bed 4, the Rare or Threatened bed, on the Connections Garden at the Australian Botanic Garden, Mount Annan.
Research at the Australian Botanic Garden is improving our understanding of which rainforest species have seeds that can be dried and stored. Experiments on Myrsine richmondensis showed that seeds could be successfully dried to about 15% relative humidity, so they are desiccation tolerant (orthodox) and have the potential to be stored ex situ.
