On the resulting maps, the researchers overlay current knowledge about vertebrate biodiversity, threatened species, and guarded areas, in addition to authorities-recognized Indigenous areas. The paper “debunks an important fantasy” in conservation circles, says Massachusetts Institute of Technology aerospace engineer Danielle Wood, who research technology and international growth however was not involved with the new work.
