They looked at more than 67,000 species, meaning about 18% of the world’s known vascular plants.AdvertisementAdvertisementThey found that 7% to 16% could lose more than 90% of their range, placing them at high risk of extinction. Examples include Catalina ironwood, or island ironwood, a rare endemic California tree, bluish spike-moss from a plant lineage dating back more than 400 million years, and roughly one third of Eucalyptus species, one of Australia’s most recognizable plant groups.The researchers came to their estimates after examining millions of records on plant locations as well as greenhouse-gas emissions scenarios for 2081-2100.A plant’s habitat is not simply a place on a map, but the full array of conditions it needs: temperature, rainfall, soils, land use and landscape features such as shade.”One way to picture this is to imagine plants trying to follow a moving ‘climate envelope.’ As temperatures warm, many species can shift northward or uphill to stay cool enough. But temperature is only part of the story,” Junna Wang, a Yale University postdoctoral researcher, and Xiaoli Dong, a professor of environmental science and policy at the University of California, Davis, said in joint comments to Reuters.AdvertisementAdvertisementWang and Dong helped lead the study publis …
