Modeling Biodiversity Dynamics in Countryside and Native Habitats
... The countryside SAR can be used to project the biodiversity response to scenarios of land-use change (Proenc- a et al., 2009). In contrast with the classic SAR, a proportion of species may remain in the landscape even if all native habitat is converted to human-dominated habitats (Figure 2). The cou ...

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.
