Nisqually Community Forest VELMA modeling.

This invited webinar will be presented to the EPA Region 10 Forest Team on January 28, 2020. We provide an overview of a set of forest and stream management modeling tools to support community-based forest management and salmon-recovery planning in Pacific Northwest (PNW) watersheds. As an example, we describe how these tools have been applied to the Mashel River Watershed in collaboration with the Nisqually Community Forest (NCF), whose members include local communities, the Nisqually Tribe, and others. The tools are designed to help inform plans for restoring hydrological and ecological processes critical to salmon recovery, and more broadly, to the functioning of entire watersheds and the ecosystem services they provide for local stakeholders. This webinar focuses on the EPA-NCF collaborative application of an EPA watershed simulator – Visualizing Ecosystem Land Management Assessments (VELMA) – to quantify long-term effects of alternative forest management and climate scenarios on key salmon habitat and water quality and quantity variables, especially peak and low flows. Model results illustrate how forest management favoring longer harvest intervals can significantly increase low summer stream flows, a topic of regional concern for salmon recovery planning in PNW watersheds. Note: This is re-presentation of a 2016 seminar has been shortened for discussion purposes with EPA Region 10 Forest Team members.
