Restoring Van Norden Meadow By Anne Chadwick, President Truckee Donner Land Trust Photography by Anne Chadwick Presentation to DSAA Forum - 18 April 2015 Truckee Donner Land Trust Explores many scenarios Considering: • Regulation • Financial • Legal • Ecology Based on: • Research • Collaboration • Expertise Land Trust Acquired Royal Gorge in 2012 Land Trust’s Royal Gorge Acquisition ~3000 acres 1,000 donors *thank you!* Public and Private funding Protected Forever Liabilities • Illegal dam • No water rights • Potential penalties • $1000 per day! x2!! Severe Drought and Mandatory Water Cutbacks Considering Options Rebuild dam • • • No Water Rights $$$ No Support from Water Agencies Two-dam solution • • • • No Water Rights Not practicable Costly Permitting 49 Acre-foot Reservoir • • • No Water Rights DSOD Compliant, but… Unacceptable to Forest Service Forest Service Position “Let me state unequivocally, if we purchase this parcel, we will NOT acquire it with the current dam configuration, nor with a secondary dam/weir.” – Joanne Roubique District Ranger Letter Dated April 30, 2014 Idea: Carve Out and Retain Dam • No water rights • Irresponsible use of donor money Meadow Restoration: The Conservation Prize Unhealthy Meadow Source: American Rivers Healthy Meadow Source: American Rivers Collaborators • • • • • • • • • • Point Blue Conservation Science (formerly Point Reyes Bird Observatory) The UC Center for Watershed Sciences Balance Hydrologics The Nature Conservancy The Truckee River Watershed Council South Yuba River Citizens League (SYRCL) Gateway Mountain Center The Trust for Public Land American Rivers The U.S. Forest Service Legacy Uses 150 Years: Transcontinental railroad Lincoln Highway Power lines Roads Pipelines Grazing The results: Loss of wetlands Reduction of habitat Encroachment of invasive grasses Alteration of the water table Good News: Degradation is Reversible Willow Flycatcher – Photo by Nick Saunders High Meadows = Crucial Habitat Perazzo Meadows Good example of restoration Perazzo Meadows – July 2014 Lush and wet in 3rd year of severe drought Meadows Tour – July 2014 Incised Channel in VNM water enters channel and rushes out of meadow What do the experts say? Catherine Davis Schnurrenberger, a botanist working with the Gateway Mountain Center, said that a healthy meadow would encourage the growth of sedges, which will out-compete invasive reed canary grass that now appears in the terrain. Josh Viers of the UC Center for Watershed Sciences pointed out that a higher water table will discourage encroachment of lodgepole pines, which currently intrude on the valley. Ryan Burnett of Point Blue Conservation Science envisions a wet meadow that will improve habitat for waterfowl and play a keystone role for migratory birds in late summer. His organization emphasizes the strategy of ‘Climate Smart Conservation,’ and it considers subalpine meadows crucial to the Sierra. “Meadows sit at the headwaters of much of California’s water supply. They provide ecological services such as water storage and flood attenuation, and are biological diversity hot spots. Many are degraded, and this makes them more vulnerable to climate change (extreme floods; warmer, drier conditions). We are working with a range of partners to restore and protect meadows and help lessen the blow of climate change.” Rod Kelsey of The Nature Conservancy anticipates that mountain meadows will have increasing importance as the climate changes. Lisa Wallace of the Truckee River Watershed Council has helped guide the successful restoration of Perazzo Meadows and she sees tremendous potential for similar results in Van Norden. “One of our highest priorities is ecological resilience. Meadow restoration will reconnect the natural floodplain and restore hydrologic function within the meadow. This will restore wetland areas that have dried out due to stream incision, water the rest of the meadow, reduce erosion, and increase riparian and aquatic habitat. There will be significant gains in habitat for birds and wildlife.” US Forest Service Among the Forest Service’s key goals is retention and restoration of ecological resilience of National Forest System lands. Ecologically healthy and resilient landscapes, rich in biodiversity, have greater capacity to adapt and thrive in the face of natural disturbances and large scale threats to sustainability. We believe the highest and best use for the area, to best serve the public and natural resource values, is restoration of the meadow to a more natural state. Photo: Elizabeth Carmel Approximately two thirds of California’s bird and amphibian species depend on meadows. Montane meadows are considered by many to be the single most important habitat in the Sierra Nevada for birds. US Forest Service Lowering the spillway would not lead to endangerment of the White Pelican. However, if the meadow is restored, habitat for a variety of bird and animal species will be enhanced, including: • Willow Flycatcher (Forest Service sensitive species and California endangered species) • Yellow Warbler (Management indicator species) • Wilson’s Warbler, • MacGillvray’s Warbler • Lincoln’s Sparrow • Mountain White-Crowned Sparrow • Meadow Voles • Sensitive Bat Species • Western Toads • Pacific Chorus Frogs (Management indicator species) California Department of Fish and Wildlife “Although [notching the dam] represents a decrease in standing water at the lake, CDFW feels that the proposed restoration of this high mountain meadow will provide more benefits to wildlife and the ecosystem than any other options. Additionally, lowering the water pressure on the dam serves as a safety measure that provides flood protection for homeowners and user downstream in case of a failure. CDFW does not believe that a reduction in the lake size will be detrimental to white pelicans and is supportive of restoration that will make the meadow more usable to a variety of native bird species, including willow flycatcher. Returning a large portion of the meadow to its natural habitat and hydrologic condition, while improving public safety, is a great plan for this property and CDFW supports this management action.”
