The Stillaguamish Tribe of Indians is a federally recognized Tribe comprised of descendants of the Stoluck-wa-mish River Tribe with more than 240 enrolled members. The Stillaguamish Tribe Reservation is located about 46 miles north of Seattle in what is now present-day Washington State.

In 2016, the Tribe published the Stillaguamish Tribe Natural Resources Climate Change Vulnerability Assessment, which identified and assessed the vulnerability of 57 individual species and 10 habitat types. The Stillaguamish Tribe utilized the NatureServe Climate Change Vulnerability Index to support its vulnerability assessment and climate resilience planning processes.
