- 4. Area of ocean needed to sustain the consumption of an average person, a nation, or the world, based on the weight of fish he, she, or they consume annually.
- 5. Species Act (ESA) U.S. law that identifies and protects endangered and threatened species and calls for recovery programs to help species recover to levels where legal protection is no longer needed.
- 9. on International Trade in Endangered Species of Wild Fauna and Flora (CITES) International treaty that bans hunting, capturing, and selling of threatened or endangered species.
- 11. Unfenced grassland in temperate and tropical climates that supplies vegetation for grazing (grass-eating) and browsing (shrub-eating) animals.
- 15. area Area that has not been disturbed by humans and that is protected by law from all harmful human activities.
- 16. Temporary or permanent removal of large expanses of forest for agriculture, settlements, or other uses.
- 17. Too many animals grazing an area for too long, leading to reduced grass cover, which in turn leads to erosion that compacts soil and reduces its capacity to hold water.
- 18. plantation Managed forest containing only one or two species of trees that are all the same age.
- 19. zone Outer zone surrounding a strictly protected inner core of a reserve where local people can extract resources sustainably.
- 22. swap Arrangement in which participating countries act as custodians of protected forest reserves in return for foreign aid or debt relief.

- 1. concession Strategy in which governments or private conservation organizations pay governments or landowners in other nations to preserve their land’s natural resources for a set amount of time.
- 2. breeding Process by which wild individuals of a critically endangered species are collected for breeding in captivity, with the aim of reintroducing the offspring into the wild.
- 3. burn Carefully planned and controlled fire that removes flammable small trees and underbrush in the highest-risk forest areas.
- 6. restoration Deliberate alteration of a damaged habitat or ecosystem to a state close to its original one.
- 7. Managed grassland or enclosed meadow often planted with domesticated grasses or other vegetation to be grazed by livestock.
- 8. forest Uncut or regenerated forest that has not been seriously disturbed by human activities or natural disasters for 200 years or more.
- 10. ecology Method of protecting terrestrial biodiversity by finding ways for humans to share with other species some of the spaces they dominate.
- 12. on Biological Diversity (CBD) International treaty that commits participating governments to reduce the global rate of biodiversity loss and to share the benefits from use of the world’s genetic resources.
- 13. hotspot Area rich in highly endangered endemic species
- 14. reserve Area that contains a strictly protected core ecosystem surrounded by a buffer zone where local people can extract resources sustainably.
- 20. Concentration of an aquatic species suitable for commercial harvesting in an ocean area or inland body of water.
- 21. forest Stand of trees resulting from secondary ecological succession. These forests develop after the trees in an area have been removed by human activities, such as clear-cutting for timber or cropland, or by natural forces such as wildfires and hurricanes.
