How Will Forests Affect Mountain Snow Storage in a Warming Climate?

Forests strongly influence snow processes and affect the amount and duration of snow storage on a landscape. Therefore, forest changes, from management activities or natural disturbances, have important consequences for spring and summer soil moisture availability, aquatic habitat, and water supply. Accounting for these effects of forest change on watersheds will become even more important under warming climate conditions, which will reduce the amount and duration of snow storage.

In this webinar, Susan E. Dickerson-Lange will present on Northwest Climate Science Center supported research that led to the creation of a conceptual model that paired relevant spatial datasets for considering the combined impacts of forest and climate change across the Pacific Northwest, USA. Predicting the effects of forest on snow storage depends on drivers that vary across locations, such as winter temperature, wind speed, cloudiness, and solar radiation. The net result is that management actions, such as timber harvesting, can have unintended effects on snow storage and duration depending on location.

Join the webinar to learn more about how to use maps of key climate and physical features across Washington, Oregon, and Idaho to optimize snow storage in forest management decisions.

Registration is required.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives.
