Vulnerable
A species classified as vulnerable faces threats, like loss of habitat and poaching, in the wild that may cause it to go extinct. These species have come under threats that have pushed them out of near threatened and into the first of the IUCN's danger-zones: vulnerable. The threat of extinction for vulnerable creatures, like the African lion, remains higher than for species of least concern while near threatened species are approaching its status or kept stable via captive breeding programs. In other words, near threatened species' problems have intensified or continued so their population has decreased to a worrisome level; they are now vulnerable.
Endangered
Endangered species populations are in severe decline and are at risk for extinctions based on several factors, such as pollution, deforestation and hunting. One notable example of this has been the bald eagle. Once highly endangered in the 1980s and early 90s due to DDT poisoning, conservation efforts have since worked so the species is classified as least concern today.
Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species (and subspecific categories) that are restricted to a defined geographical area.
