TROPICAL RAINFORESTS: Disappearing Opportunities
Modern Extinction Estimates
Estimate and Method of estimation | % Global Loss | 10 million sp. | 30 million sp. | Source |
0.2-0.3% annually based on tropical deforestation rate of 1% annually | 2-3% | 20,000-30,000 | 60,000-90,000 | Wilson |
2-13% loss between 1990 and 2015 using species area curve and increasing deforestation rates | 0.8-5.2% | 8,000-52,000 | 24,000-156,000 | Reid |
Loss of half the species in the area likely to be deforested by 2015 | 8.3% | 83,000 | 250,000 | Raven |
Fitting exponential extinction functions based on IUCN red data books | 0.6-5% | 6,000-50,000 | 18,000-150,000 | Mace |
