Bird conservation in tropical ecosystems

Tropical ecosystems are generally under greater pressure than their temperate counterparts from human population growth, agricultural expansion and a host of related factors. They also support 87 ...

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.
