Salmon are an important resource to the ecosystems, economy, and culture of the Kenai Peninsula, Alaska. However, salmon are under increasing stress due to warming water temperatures and decreasing stream flow. Groundwater is a major contributor to many streams that can help maintain fish habitat during low flows and contributes cooler water that regulates stream temperatures in the warm summer months. As the climate warms, the ability for groundwater to cool stream temperatures will likely become more critical to streams that are used by salmon, such as Beaver Creek near Kenai, Alaska. Preliminary analysis of historical streamflow data indicates that on average, Beaver Creek receives nearly 80% of its flow...

Berry-producing plants, a key resource in Alaska Native communities, provide primary subsistence and have been integral to maintaining cultural cohesion, sense of place, and physical ties to the surrounding landscape. Despite the importance of berry-producing plants, relatively little is known about their vulnerability to changes in climate and environmental conditions. The dynamics of insect populations are strongly related to climate; however, very little is known about the insect pollinators of berry plants in Arctic and sub-Arctic ecosystems. This interaction between plants and pollinators is critical to plant communities and for providing fruit resources to Indigenous communities. Numerous plant species...

The Situk River is among the most productive resource in Alaska, with nine native fish species and 10 times the density of juvenile coho salmon than any other Southeast Alaskan watershed. The associated fisheries in the Situk River and its adjoining estuary drive a $2 million economy for the community of Yakutat (population 600), with 89 percent of the households harvesting salmon for subsistence purposes. The Yakutat foreland area that encompasses the Situk River watershed is a vast landscape of low gradient drainages with forested mosaics of side channels and pools that are responsible for up to 80 percent of coho salmon production. These highly productive aquatic habitats are sensitive to even small shifts in...

Stream discharge and temperature patterns are being altered by climate change, but documenting these changes on the community level is challenging without community partners trained in suitable data collection techniques. The USGS Juneau Field Office is collaborating with the Yakutat Tlingit Tribe (YTT), the Southeast Alaska Tribal Ocean Research (SEATOR) network, and the Southeast Alaska Watershed Coalition (SAWC) to integrate stream discharge and stream temperature monitoring into ongoing Tribal-led climate adaptation, water quality, and species management projects. Stream discharge and temperature data is limited in Southeast Alaska and improving the spatial coverage of this data would be mutually beneficial...
