Understanding interactions between threatened plants and their pollinators and symbiotic partners is fundamental to secure their long-term survival either in their natural habitat or ex-situ collections. My research aims at documenting the pollination biology of threatened plants and trees, identify orchid mycorrhizal partners and implement methods to propagate orchids from seed for conservation purposes.
Current projects focus on one of New Zealand’s rarest tree, the Bartlett’s rata (Metrosideros bartlettii) with only 13 individuals left in the wild, and the helmet swamp orchid (Corybas carsei) with a few plants at a single site in New Zealand.
