The Great Gray Owl (Strix nebulosa) is a California Endangered Species, with an estimated population size of only 100-200 pairs in the state. It is the largest owl in North America and one of the largest owls in the world. It is also one of the most reclusive bird species, which provides challenges in studying its life history.

The purpose of this handbook is to demonstrate how climate change considerations can be integrated into planning and design for Sierra meadow restoration projects and provide recommendations of best management practices to ensure restored meadows are resilient to climate change. Our approach combines a traditional climate change vulnerability assessment with Point Blue’s climate-smart restoration principles to describe both the potential vulnerabilities that climate change poses to achieving restoration goals as well as specific restoration and management actions that can help address and reduce identified vulnerabilities.

Meadows of the Golden Trout Wilderness (GTW) are an extremely valuable component of the landscape, providing numerous benefits to society. In 2012, the National Fish and Wildlife Foundation funded a partnership between CalTrout, Trout Unlimited, and American Rivers to evaluate meadow resources in the GTW and prioritize meadows for restoration. We hope the information we provide here will help partners and the US Forest Service work together to increase the pace and scale of meadow restoration in the GTW.

We investigated the historical use and long-term efficacy of hand-built check dams to repair eroded meadows of Sequoia and Kings Canyon National Parks (SEKI) to inform the design for restoring a large erosion gully in Cahoon Meadow, SEKI. Archive documents show that, for 34 years from 1948 to 1981, a summer-seasonal team of SEKI employees, the Soil and Moisture Conservation Crew (S&MCC), built and maintained check dams in 20 back country meadows and 1 front country meadow, and their erosion control efforts were requested, but never implemented, at an additional 33 meadows. S&MCC activities were focused on mitigating the impacts of grazing that occurred from ~1870 to 1985. The two meadows with the longest grazing history, Williams and Sugarloaf, were consistently rated as high priorities for erosion-control and received the most S&MCC check dam work. In 2015 we conducted field investigations in these two meadows, relocating as many dams as possible to determine how effective they were at accumulating sediment after 30 years of maintenance followed by 35 years with no work. We found 41 S&MCC check dams, 35 in Sugarloaf and 6 in Williams, and measured their channel dimensions, slope, sediment accumulation, and functionality. All but 2 of the dams were non-functional, retaining no water, and even dams in small, shallow sloping channels had failed. The maximum sediment accumulation depth was 1.2 meters, just upstream of a dam built in 1948, in a gully that had been 2.5 meters deep. On average, the sediment depth accumulated behind dams was 26% of the former gully depth. Nowhere did enough sediment accumulate behind a dam to fill in the local gully and restore the original level topography of the meadow. Although 30+ years of dam building and maintenance succeeded in locally depositing sediment to about a quarter of the eroded gully depth, the gully in Cahoon Meadow is deeper and wider than any of the dammed sections of either Williams or Sugarloaf Meadows. Wider, taller structures would be required in Cahoon’s gully and these would be significantly more difficult to design, build, and maintain than the S&MCC dams and require 100 years or more to accumulate enough sediment to completely restore original topography.

In this project, we sought to identify putative climate change refugia and connectivity between meadows across the Sierra Nevada and to use data on persistence, stability, and genetic diversity of mammal populations to validate these hypotheses. We addressed California Landscape Conservation Cooperative priorities of scale by analyzing across the Sierra Nevada. We involved state and federal natural resource managers throughout the project; some are already beginning to incorporate results. Our products focused on maps and tools that are user-friendly and that allow managers to make decisions and set landscape conservation priorities. We are communicating project outcomes directly to CA LCC partners to aid in decisions from immediate, small-scale adaptation projects to region-wide changes in use, development, and planning for state and federal land management. Our results will help managers to prioritize areas and landscapes that are critical to maintaining biodiversity in the Sierra Nevada in the face of climate change and to focus limited resources for effective adaptation efforts.

The goal of this project was to identify priority meadows for restoration in the Storrie Fire nexus watersheds and develop restoration designs for the priority meadows. We used a rigorous prioritization process using the American Rivers’ meadow condition scorecard, the Sierra Meadow Prioritization Tool, and additional field assessments to reduce a dataset of 90 meadows into a smaller subset of priorities, resulting in 8 high priority meadows set to be restored in 2021.

This report briefly describes the methods we developed and presents findings from applying the methods in the Yuba and Mokelumne River watersheds.The methods we developed and the on-the-ground data for the Yuba and Mokelumne watersheds supply a replicable template that may be applied in other watersheds to focus meadow restoration effort where it will provide the greatest value. The prioritized list of meadows we developed galvanized support of the top restoration candidate (see From Prioritization to Restoration, below) and, within six months, resulted in completed permits and three funding proposals.Our ultimate goal is to accelerate and improve meadow restoration. The steps we took in this project focus on providing the infrastructure necessary for meadow restoration to gain and sustain momentum into its next phase, where watershed-scale impacts are anticipated.

Natural Range of Variation (NRV) assessments (essentially equivalent to Historical Range of Variation [HRV] assessments) provide baseline information on ecosystem conditions (composition, structure, and function) that can be compared to current conditions to develop an idea of trend over time and an idea of the level of departure of altered ecosystems from their “natural” state (Morgan et al. 1984, Manley et al. 1995, Landres et al. 1999, Wiens et al. 2012; see Methods). These trend assessments form part of the basis for the assessment of ecological integrity that is required in the 2012 Forest Service Planning Rule. NRV assessments were carried out for 11 terrestrial ecosystems by the Pacific Southwest Region Ecology Program between October, 2012 and May, 2013, using historical information (primarily from the pre-Euroamerican period, 16th century to the mid-19th century) as well as information from modern-day reference ecosystems and other sources. This is the meadow NRV assessment.
