FOR201H1 Lecture Notes - Lecture 9: Biological Engineering, Terra Preta, Agroforestry
Document Summary
For210h1: lecture 9 - tropical forests and global change - from paleo perspectives to. Parks vs. people & the land sparing vs. sharing debate. In-situ conservation: conservation efforts aim to save species by maintaining their habitats. Protected or managed areas of natural habitat. Ex-situ conservation: involves trying to conserve species outside of their natural habitats. Zoos, botanical gardens, captive breeding areas, gene banks. While species and genes can be conserved ex-situ, ecosystems and species interactions are removed. It is very difficult to conserve natural levels of genetic variation of most organisms in captivity. Many organisms are difficult to breed or propagate in captivity. Zoos and botanical gardens focus overwhelmingly on charismatic fauna and flora, insects and other small organisms are almost completely neglected. Capture and trade in endangered organisms may be encouraged by ex-situ. Known or predicted diversity of well-known taxa. Presence of species of special conservation importance. Size of forested or other habitat area.
