For example, hummingbirds find nectar by color, so the flowers that attract them are tube-shaped, are bright red, and have virtually no scent Often, plants can only be pollinated by one type of pollinator, so they evolv ...

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.
