Introduced mammal impacts on seabirds in the Îles Éparses

Introduced predators have had the greatest effect through direct predation, but this effect can now be mitigated by modern eradication te ...

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.
