The Ecological Basis of Conservation Heterogeneity, Ecosystems

Application of this principle requires consideration of the fluxes across ecosystem boundaries and identifying linkages with surrounding ecosystems. ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
