| biosphere reserves | world heritage site identified by the IUCN as worthy for national park or wildlife refuge status because of high biological diversity or unique ecological features |
| clear-cutting | cutting every tree in a given area, regardless of species or size; an appropriate harvest method for some species; can be destructive if not carefully controlled |
| closed-canopy forests | a forest where tree crowns spread over 20% of the ground; has the potential for commercial timber harvests |
| corridors | a strip of natural habitat that connects two adjacent nature preserves to allow migration of organisms fro mone place to another |
| debt for nature swap | forgiveness of international debt in exchange for nature protection in developing countries |
| deforestation | cutting down trees |
| desertification | conversion of productive lands to desert |
| ecosystem management | an integration of ecological, economic, and social goals in a unified systems approach to resource management |

| GIS: geographic information systems | spatial data, such as boundaries or road networks and computer software to display and analyze those data |
| Landscape ecology | the study of the reciprocal effects of spatial pattern on ecological processses. A study of the ways in which landscape history shapes the features of the land and the organisms that inhabit it as well as our reaction to, and interpretation of, the land |
| man and biosphere program | a design for nature preserves that divides protected areas into zones w/different purposes. A highly protected core is surrounded by a buffer zone and peripheral regions in which multiple use resource harvesting is permitted |
