Ten hotspots were originally identified by Myer; [1] the current 36 used to cover more than 15.7% of all the land but have lost around 85% of their area. [8] This loss of habitat is why approximately 60% of the world's terrestrial life lives on only 2.4% of the land surface area.

Key Biodiversity Areas (KBA) are geographical regions that have been determined to be of international importance in terms of biodiversity conservation, using globally standardized criteria published by the IUCN as part of a collaboration between scientists, conservation groups, and government bodies across the world.

The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (), the global conservation organization, as priorities for conservation.According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions".
[10] [11] The recent HERMES project lists more than 2000 species associated with cold-water coral reefs worldwide. [12] As well as flourishing live coral, the dead coral frameworks and rubble that are frequently found close by attract a myriad of fauna from the microscopic to the mega, [ 13 ] and may be fundamental in coral ecosystem replenishment.
This biodiversity hotspot is known for being the home of the Sierran giant sequoia tree and its close relative the coast redwood. [1] In 1996, the Province was designated as a biodiversity hotspot allowing it to join ranks among 33 other areas in the world with many endemic species. To be named a biodiversity hotspot, an area has to contain ...
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.
Since 1988 the hotspots increased from 10 to 34. Of the total 34 hotspots currently present, 16 of them are in tropical regions (as of 2006). [34] Researchers have noted in 2006 that only 2.3% of the world is covered with biodiversity loss hotspots, and even though only a small percentage of the world is covered in hotspots, it host a large ...
