PNW Ecotone

“PNW Ecotone” is a podcast of the Pacific Northwest Research Station that highlights recent science findings, tools, and timely research topics from our 11 laboratories and centers in Oregon, Washington, and Alaska.

In ecology, an “ecotone” refers to a transitional area, an interface, between two distinct landscape types. This interface shares characteristics of each area but also has unique qualities of its own. We view “PNW Ecotone” in much the same way—as a transitional interface that connects two communities—in our case, scientists and the people their work serves.

Station scientists are working to better understand cities as ecosystems and demonstrate how nearby nature provides important benefits and services. (4:19).
