Habitat. Refers to an individual, species-specific use of a wildlife-habitat type. “Habitat” is the place, including physical and biotic conditions, where a plant or animal usually occurs and is fundamentally linked to the distribution and abundance of species. Species may depend on a Habitat or structural characteristics for part or all of its life history or may exhibit a high degree of adaptability using more than one Habitat. The relationship of species to Habitat is scale-dependent and varies from geographic range, home range, to local or site-specific Habitat components. “Habitat” includes areas of high relative density or species richness, breeding Habitat, winter range, and movement corridors. These areas may also include Habitats that are of limited availability or high vulnerability to alteration. Other examples include: remnant patches of mature mixed Puget Sound lowland forest, caves and cliffs, snag-rich areas and downed logs, riparian areas, lakes and ponds, wetlands and their buffers, and heron rookeries. (Ord. 5683, 6-26-06, § 40)

Habitat Type. Place where an animal or plant normally lives and which is characterized by a dominant plant form or physical characteristic. A “Habitat Type” is based on actual conditions and consequently can be mapped, and is assumed to contain all the essential needs for a species’ maintenance and viability. Habitat Types are not species-specific because they are based on the similarity of many wildlife species using a suite of vegetation types. (Ord. 5683, 6-26-06, § 40)
