This is a project, funded by Conservation International, with which Professor Pimm is closely involved. From a CI press release:
Co-chaired by renowned biologist and Harvard professor Edward O. Wilson and Intel co-founder Gordon E. Moore, "Defying Nature's End" is a collaborative effort by a diverse group of prominent scientists, economists and business leaders. Called a "practical agenda" for conserving the 25 hotspots identified as the most biodiverse areas on Earth, it aims for nothing less than pulling humanity back from the brink of an extinction crisis many scientists agree could be worse than the episode that wiped out the dinosaurs.
