[5], Three of the known populations of Rhizanthella gardneri are protected within nature reserves,[3] and a concerted initiative has been launched to safeguard this species for future generations. Compared to other plants, this orchid has the fewest number of genes in its chloroplast (a sub-unit of the plant cell that has its own genome). Professor Brundrett has been working with the Department of Environment and Conservation and volunteers from the West Australian Native Orchid Study and Conservation Group to locate these unique orchids.
