Grass Valley, Calif. March 5, 2019 –  The Sierra Science Series will welcome Dr. Sarah Yarnell, UC Davis Research Hydrologist, to present current research in meadow restoration with a presentation titled, An Experimental Study of Beaver and Beaver Dam Analogue (BDA) Restoration Techniques in Childs Meadow.

The presentation will be held on Tuesday evening, March 12th from 6:30 – 7:30 pm, in the Multipurpose Center, building N12-103, at the Nevada County Campus. Come early and enjoy a meet-and-greet and refreshments at 6:00 pm.

Meadows play an important role in water storage and flood prevention. However, many Sierra Nevada meadows have been transformed from multi-thread channels with annually inundated floodplains into single-thread channels that store less water, store less carbon and have reduced habitat quality for a diverse suite of meadow-associated wildlife.

Dr. Yarnell aims to understand the role of beavers and beaver-dam-like structures in restoring degraded meadow resources. This presentation will report initial findings and lessons learned on an adaptive management experiment to enhance water, carbon, and wildlife in Childs Meadow, a 290-acre meadow just south of Lassen National Park. A portion of the meadow was restored using combinations of Beaver Dam Analogues, grazing enclosures, 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.

The Sierra Science Lecture Series is presented by Sierra College Nevada County Campus and Sierra Streams Institute.
