| Movement corridor | Narrow strips or series of small clumps of habitat connecting otherwise isolated patches. |
| Zoned reserve | An extensive region that includes relatively undisturbed by humans surrounded by areas that have been changed by human activity and are used for economic gain. |
| Critical Load | The amount that can be absorbed by plants without damaging ecosystem integrity. |
| Biological magnification | Biomass at any given tropic level is produced from a much larger biomass. |
| Assisted migration | The translocation of a species to a favorable habitat beyond it's native range to protect the species from human-caused threats. |
| Sustainable environment | Economic development that meets the needs of people today without limiting the ability of future generations to meet their needs. |
