- Grasses and low shrubs that are less hardy than early successional plant 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.

5 True/False questions
ecological extinction → So few members remain that the species cannot maintain its ecological role, or members only survive in captivity.
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 → Plant species found in the early stages of succession that (1) grow close to the ground, (2) can establish large populations quickly under harsh conditions, and (3) have short lives.
flyway → Generally fixed route along which waterfowl migrate from one area to another at certain seasons of the year.
endangered species → Wild species with so few individual survivors that the species could soon become extinct in all or most of its natural range.
