Document Summary
Natural habitats may disappear while conserving the species. Inbreeding of zoo specimens may lead to infertility/ow infant survival. An alternative to this is to save species in the wild. Gap analysis - seeks out unprotected landscapes in rich species. Protect ngoush for viability of all native species in a given region. Manage at regional scale large enough to accommodate natural disturbances. Plan over a period of centuries for the evolution of the ecosystem. Allow for human use at a level that does not result in lots of ecological degradation. 1995 - wolves reintroduced to yellowstone national park. Reduced populations of coyotes - increased pops of small mammals. 10% tree cover to be a forest. 30,000 ha (what"s ha?) are deforested per year. Conversion to agriculture, ranching, loggings, biofuel, palm oil. Logging and fragmentation of private forest land. About 12% of world forests are now protected.
