The biodiversity hotspots are regions known to hold especially high numbers of species found nowhere else, yet their remaining habitat combined covers a little more than two percent of Earth's land surface. According to the criteria developed by Myers et al. (2000), a hotspot must meet two thresholds in order to qualify: 1) it must have at least 1500 endemic, native vascular plant species, and 2) it must have already lost at least 70% of its primary, native vegetation.Hotspots analysis is in constant evolution. There are two major ways in which hotspots can change over time. The first is a real effect. Threats and their impacts change, meaning that some places may become more threatened while others may recover....

Resilient Biodiversity Hotspots This layer is an older version of one of the South Atlantic LCC indicators in the landscapes “habitat aggregate”, which is intended to capture connections across all terrestrial ecosystems. It is an index of mostly natural, high-diversity areas potentially resilient to climate change. This indicator was most recently updated in Blueprint 2.2 to incorporate more recent data from TNC’s Resilient Land project. The updated indicator also has 8 categories based on standard deviations from the mean, rather than the two categories in this version, and uses an improved resampling method. Reason for Selection Resilience scores quantify a combination of landscape diversity and local connectedness....

The biodiversity hotspots are regions known to hold especially high numbers of species found nowhere else, yet their remaining habitat combined covers a little more than two percent of Earth's land surface. According to the criteria developed by Myers et al. (2000), a hotspot must meet two thresholds in order to qualify: 1) it must have at least 1500 endemic, native vascular plant species, and 2) it must have already lost at least 70% of its primary, native vegetation. In the updated analysis, Mittermeier et al. (2004) recognize 34 hotspots which together hold 50% of the world's plant species and 42% of all terrestrial vertebrates as endemics. As evidence of their urgency for global conservation, hotspots also hold...
