Habitat Connectivity

The Pacific Northwest, and in particular, the region between the Cascades to the Coast, supports working private and public lands as well as habitats and open spaces for native fish and wildlife. 

Wildlife need different types of habitat to meet all of their life cycle needs, and like humans that require transportation corridors to safely and efficiently move from one place to another, wildlife need the places where they feed, reproduce, raise their young, and migrate to connect. Healthy habitat connections reduce stress on wildlife and better allow animals to adapt to changing conditions on the landscape.​


Understanding habitat connectivity requires science and information about species and their life history needs as well as the current status and projections for land use and changing conditions throughout the region.​

To obtain this information, Oregon and Washington have developed Wildlife Habitat Connectivity Work Groups.

The Oregon Conservation Strategy identifies “Barriers to Fish and Wildlife Passage” as one of the key conservation issues for the state of Oregon.


Oregon's goal is to provide conditions suitable for natural movement of animals across the landscape.

The Washington Wildlife Habitat Connectivity Working Group is an open collaborative science-based effort to produce tools and analyses that identify opportunities and priorities to provide habitat connectivity in Washington and surrounding habitats.

The goal of the Washington Connected Landscapes Project is to provide a series of scientific analyses and tools that use the best available science to identify important wildlife habitat linkage areas in Washington State and neighboring habitats.

Their scientific analyses and products can be found here.
