Where along the Pacific Coast is the geographic distribution of Ixodes pacificus concentrated?

Answer

Its range spans from Southern California northward through Oregon and Washington.

The distribution map for the Western Blacklegged Tick, *Ixodes pacificus*, is geographically concentrated along the Pacific Coastline. The established historical range extends vertically along this region, starting from Southern California and continuing northward across Oregon and into Washington state. While the primary corridor is coastal, the text notes that the tick can also be detected in adjacent inland areas, provided the necessary favorable habitats, such as oak woodlands or forested environments with sufficient leaf litter, are present to support their lifecycle.
