I am a Research Scientist responsible for the day to day running of the Departments ex situ seed conservation facility, the Threatened Flora Seed Centre. I am involved with all aspects of the seed conservation process from the collection, cleaning and long term storage of seeds to germinating seeds to determine their viability or for use in translocations.
