You may not know it, but Australia is facing an extinction crisis. With the worst rate of mammalian extinction in the world, over 1,700 species of animals and plants are currently at risk of becoming extinct in Australia. The future of biodiversity conservation relies on multiple factors, including removing native animals from the dangers of introduced predators, changing the culture of clearing land, and having support of the government, conservationists, and society as a whole. These changes would help populations to recover, however when the gene pool of a species has bottlenecked so much, even if the population size increases, their genetic health will remain poor. To avoid the current health problems such as all koalas having chlamydia and Tasmanian devils having infectious facial tumours, genetic rescue is potentially the solution. With Dr Weeks and his colleagues leading the way, endangered and threatened Australian flora and fauna will hopefully flourish once again.
