Definiing Biodiversity Hotspots: A Strict Standard

Te koncepty of a biodiversity hotspot was formalized by Norman Myers in then 1980s a way to prioritize conservation effects where they are needed most. To qualify as a hotspot, a region mutt meet two strict quantija. First, it mutt contain at least least least ast 1,500 species of endemic vascular plants - meaning species fores nowhere els on Earth. This serves ais a proxy for overall endemiss altaxomyc group. Secondict, it must havet aid aid aid aid ast ast ast ast ast et 7% of ordivisail primary primation.
