Cross conducts much of his fieldwork in Western Australia’s Kimberley region, where he sidesteps deadly wildlife and endures broiling 104-degree Fahrenheit temperatures in suffocating humidity in search of elusive carnivorous plants. A quarter of the world’s 860 known carnivorous plant species are at risk of extinction as a result of climate change and threats like land clearing and poaching, according to a study Cross and his colleagues recently published in Global Ecology and Conservation.
