- a Species that is found in only one area. Such species are especially vulnerable to extinction.
- b Value of an organism, species, ecosystem, or the earth's biodiversity based on its usefulness to us.
- c So few members remain that the species cannot maintain its ecological role, or members only survive in captivity.
- d Convention on International Trade in Endangered Species. Lists (1) some 900 species that cannot be commercially traded as live specimens or wildlife products because they are in danger of extinction and (2) restricts international trade of 29,000 other species because they are at risk of being threatened.

5 True/False questions
wildlife resources → Manipulation of populations of wild species (especially game species) and their habitats for (1) human benefit, (2) the welfare of other species, and (3) the preservation of threatened and endangered wildlife species.
nonnative species → Species that migrate into an ecosystem or are deliberately or accidentally introduced into an ecosystem by humans.
minimum dynamic area (MDA) → Estimate of the smallest number of individuals necessary to ensure the survival of a population in a region for a specified time period, typically ranging from decades to 100 years.
rare species → Species that (1) has naturally small numbers of individuals, often because of limited geographic ranges or low population densities, or (2) has been locally depleted by human activities.
midsuccessional plant species → Grasses and low shrubs that are less hardy than early successional plant species.
