Some animal species are adaptable to cities and suburbs, and their populations are holding steady—or even increasing to sometimes alarming numbers. Typical urban wildlife includes raccoons, crows, and coyotes, and introduced species such as opossum, European starlings, and rock pigeons.

Other species in the ecoregion have declined significantly over the past 100 years. Their habitats have been altered and fragmented by development and use.

Notable population declines have occurred in the Taylor’s checkerspot butterfly, the Oregon spotted frog, the western pond turtle, the northern spotted owl, the marbled murrelet, and the western gray squirrel (not to be confused with its ubiquitous invasive cousin, the eastern gray squirrel).
