| patch | surface area that differs from its surroundings in nature or appearance |
| scale | spatial or temporal dimension of an object or process, characterised by both grain and extent |
| Landscape Ecology | concepts theories and methods that examine the importance of spatial patterning on interacting ecosystems |
| configuration | specific arrangement of spatial elements; used synonymously with spatial or patch structure |
| connectivity | spatial continuity of a habitat or cover type across a landscape |
| corridor | relatively narrow strip of a particular type differing from adjacent areas |
