The entire wild population of Mount Imlay mallee trees was torched in one fire during the Black Summer of January 2020, but scientists are drawing on their bank of seeds to regrow the critically endangered eucalypt.  It’s such a rare species there are only two known trees left, one mature and one juvenile tree growing in the Australian National Botanic Gardens in Canberra.  Before bushfires swept northwards from Mallacoota, across the NSW-Victorian border, there were just 55 of the extremely rare mallees growing on their namesake Mount Imlay, west of the small town of Eden on the NSW South Coast.  Federal Environment Minister Sussan Ley visited the gardens on Wednesday to launch a seed banking strategy with Greening Australia, with $5 million in public funding for the scheme that collects, stores and propagates seeds of rare plants.
