Global Climate Change A Major Threat ! A Unique Opportunity ?
An Extinction Crisis We are losing species We are losing forest and other habitats We are seeing the erosion of critical ecosystem services
Critically Endangered and Endangered Primates 32.4% CR + EN
Be Strategic Set Priorities (based on the best available Science)
Basic Premises All biodiversity is important, and all nations should do everything possible to conserve their living resources, but …
Basic Premises Biodiversity is by no means evenly distributed over the face of our planet Rather, it is heavily concentrated in a relatively small total area, a large portion of which have been heavily impacted by human activities
and…. as it turns out, these areas also happen to have some of the highest ecosystem service values, and are thus especially valuable in terms of human well-being – providing us with many potential Win-Win Situations
Setting Priorities Hotspots High Biodiversity Wilderness Areas Megadiversity Countries
HOTSPOTS Prioritizing Areas of High Irreplaceability (Endemic Species) and High Threat
HOTSPOTS Norman Myers 1988, 1990 Conservation International 1989-1995, 1996-1999, 2002-2004 MacArthur Foundation 1989 - ~1999
HOTSPOTS Earth’s 35 Richest and Most Endangered Ecoregions
HOTSPOTS Original Extent23,490,101 km2 15.7%of Earth’s land surface
HOTSPOTS 86+% Lost
HOTSPOTS Area Remaining Intact 3,385,341 km2 2.3%of Earth’s land surface
Plant Endemism in the Hotspots 150,000 species 50%of all plants as endemics
Vertebrate Endemism in the Hotspots 12,065 species 42%of all vertebratesas endemics
Threatened Species in Hotspots (CR, EN, VU) Birds 83% Mammals 82% Amphibians 90%
HOTSPOTS:KEY POINTS Not Just Tropical Rain Forest Not Just Species Richness or Endemism Concentration of Endemism at Higher Taxonomic Levels (Endemic Genera, Families) Deep Lineages / Evolutionary History
