Another example is, the tiger keeps the population of its prey such as antelope, deer, boar, and buffalo stable so there isn't a large increase in numbers for those particular species. If predators were removed from ...

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.
