Threatened Species are defined under the Endangered Species Act as those species likely to become endangered in the foreseeable future. Values are characteristics of things that make them more or less desirable, important, or useful. Wetlands are habitats that are seasonally inundated with water, and that typically have special soils and vegetation.
