- extinction
- the irrevocable elimination of species; can be a normal process of the natural world as species out-compete or kill off others or as environmental conditions change
- habitat conservation plans
- agreements under which property owners are allowed to harvest resources or develop land as long as habitat is conserved or replaced in ways that benefit resident endangered or threatened species in the long run. Some incidental "taking" or loss of endangered species is generally allowed in such plans
- invasive species
- organisms that thrive in new territory where they are free of predators, diseases or resource limitations that may have controlled their population in their native habitat
- HIPPO
- Habitat destruction + invasive species + pollution + population (human) + overharvesting = leading causes of extinction
- existence value
- the importance we place on just knowing that a particular species or a specific organism exists
- biodiversity
- the genetic, species, and ecological diversity of the organisms in a given area
- threatened species
- while still abundant in parts of its territorial range, this species has declined significantly in total numbers and may be on the verge of extinction in certain regions or localities
- biodiversity hot spots
- areas with exceptionally high numbers of endemic species
- overharvesting
- harvesting so much of a resource that it threatens its existence
- vulnerable species
- naturally rare organisms or species whose numbers have been so reduced by human activities that they are susceptible to actions that could push them into threatened or endangered status
- gap analysis
- a biogeographical technique of mapping biological diversity and endemic species to find gaps between protected areas that leave endangered habitats vulnerable to disruption
- endangered species
- a species considered to be in imminent danger of extinction
