- wildlife management
- local extinction
- midsuccessional plant species
- Endangered Species Act of 1973
- a 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.
- b Occurs when a species disappears from a part of its range but persists elsewhere.
- c requires the federal government to protect actively each of the hundreds of species listed as endangered-regardless of the economic effect on the surrounding towns or region.
- d All free, undomesticated species. Sometimes the term is used to describe only free, undomesticated animal species.
- e Grasses and low shrubs that are less hardy than early successional plant species.
5 Multiple choice questions
- 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.
- Wildlife species that have actual or potential economic value to people.
- Wild species tamed or genetically altered by crossbreeding for use by humans for food (cattle, sheep, and food crops), pets (dogs and cats), or enjoyment (animals in zoos and plants in gardens).
- Value of an organism, species, ecosystem, or the earth's biodiversity based on its existence, regardless of whether it has any usefulness to us.
- So few members remain that the species cannot maintain its ecological role, or members only survive in captivity.
5 True/False questions
CITES treaty of 1975 → 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.
early successional plant species → Mostly trees that can tolerate shade and form a fairly stable complex forest community.
endangered species → Wild species with so few individual survivors that the species could soon become extinct in all or most of its natural range.
ecosystem approach → Goal: to protect species from premature extinction.
Strategies: identify endangered species; protect critical habitats.
Tactics: legally protecting endangered species; propagating endangered species in captivity; reintroducing species back into suitable habitats.
instrumental value → Value of an organism, species, ecosystem, or the earth's biodiversity based on its usefulness to us.
