endangered species

Scientific

1. A plant or animal species existing in such small numbers that it is in danger of becoming extinct, especially such a species placed in jeopardy as a result of human activity.

Other factors include overhunting, intentional extermination, and the accidental or intentional introduction of alien species that outcompete the native species for environmental resources.
