Endangered Plant & Species

These are plant or animal species existing in such small numbers that they are in danger of becoming extirpated; this includes species that are in jeopardy as a result of human activity. A principal factor in the endangerment or extirpation of a species is the destruction or pollution of its native habitat. Other factors include overhunting, intentional extermination and the accidental or intentional introduction of alien or invasive species that outcompete the native species for environmental resources.
