Nest Predation Processes and Farmland Birds
... The most important cause of population declines of wild animals is habitat loss (Primack 1993; Meffe and Carroll 1994). The process of habitat loss involves at least four phenomena: Reduction in habitat area (Andrén 1994), habitat fragmentation (Andrén 1994; Noss and Csuti 1994) habitat degradation ...

This is suggested by recognition that the rate of collapse of hollow-bearing trees may exceed replacement in some landscapes. We ...

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.
