Come learn about the Beaver Dam restoration techniques in Childs Meadow by Dr. Sarah Yarell, Research Hydrologist, from UC Davis.

Event Details

The topic of the March Sierra Science Presentation is An Experimental Study of Beaver and Beaver Dam Analogue (BDA) Restoration Techniques in Childs Meadow, presented by Sarah Yarnell. 

The presentation will be held on Tuesday evening, April 9th from 6:30 – 7:30 pm, in the Multipurpose Center, building, N-12, at the Nevada County Campus. Come early and enjoy a meet-and-greet and refreshments at 6:00 pm.

Intensive livestock grazing and widespread removal of beaver and willows, coupled with other land uses, have transformed many of the Sierra Nevada’s meadows from multi-thread channels with annually inundated floodplains into single-thread, incised channels that store less water, less carbon, and have reduced habitat quality for a diverse suite of meadow-associated wildlife. Childs Meadow is a 290-acre meadow just south of Lassen National Park that is emblematic of this transformation. The Nature Conservancy (TNC) acquired the property in 2007. In 2015, TNC, UC Davis, USDA Forest Service – Pacific Southwest Research Station, and Point Blue began an adaptive management experiment to evaluate the potential for beaver dam analogs (BDAs) to enhance water, carbon, and wildlife in Childs Meadow. We restored a portion of the meadow using combinations of BDAs, grazing exclosures, and willow staking in fall 2015 through fall 2016. The project is a modified before-after-control-impact design evaluating carbon flux; water quality, timing, and storage; and effects on meadow associated birds and amphibians. We aim to understand the role of beavers and beaver-dam-like structures in restoring degraded meadow resources and evaluate the relationships between grazing, beavers, and these resources. We report on initial findings and lessons learned so far in the process to help inform the growing use of BDAs as restoration tools in degraded Sierra Meadows.
