PHS on the Web

Click here to enter PHS on the Web

PHS on the Web is a Washington Department of Fish and Wildlife web-based, interactive map for citizens, landowners, cities and counties, tribal governments, other agencies, developers, conservation groups, and interested parties to find basic spatial information about Priority Habitats and Species (PHS) in Washington State. PHS is a source of best available science that can inform local planning activities, development projects, conservation strategies, incentive programs, and numerous other land use applications.

The species and habitats that appear on the map are informed by WDFWs PHS List. The map displays known locations of Priority Habitats and Priority Species provided by agency biologists and other verified sources. Data is updated as new information is gathered and verified.

This map contains known errors: There are many places where Priority Species and Priority Habitats exist on the landscape which are not shown on this map. Exhaustive surveys of all Priority Species and Priority Habitats have not been conducted. Conversely, this map may contain data that is out of date. While great care is taken to provide accurate information, location of species changes over time and surveys may depict former locations. Accordingly,  before making final decisions about a project or plan using this map, WDFW strongly recommends field verification by a fish and wildlife biologist or habitat expert to make determinations about species presence, absence, or exact location.

Please note: The specific location of some fish and wildlife information is not available on PHS on the Web. We mask these “sensitive” locations to minimize the risk of human interference. Eligible landowners, university researchers, government agencies, tribes and some others may qualify to receive the unmasked data. Please visit WDFWs PHS Data Release web page for more information about how to receive sensitive data.
