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.

This report brings together recent survey results from state and federal agencies and other groups, and provide an updated range map and population estimate for Willow Flycatcher in the Sierra Nevada.

The Institute for Bird Populations is teaming with the National Fish and Wildlife Foundation and numerous public and private land managers to develop, assess, and refine bird-friendly meadow restoration efforts. This report is provides information relating to the development of a monitoring protocol for assessing how bird populations respond to meadow restoration in the Sierra Nevada. Monitoring visits included point count surveys, area searches, and vegetation assessments. This report describes results of the pre- and post-restoration monitoring completed at 59 meadows (including restoration and reference meadows) during 2012.

A USGS comprehensive national assessment of carbon (C) storage and flux (flow) and the fuxes of other greenhouse gases (GHGs, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)). These carbon and GHG variables were examined in the Western United States for major terrestrial ecosystems (forests, grasslands/shrublands, agricultural lands, and wetlands) and aquatic ecosystems (rivers, streams, lakes, estuaries, and coastal waters) in two time periods: baseline (the first half of the 2000s) and future (projections from baseline to 2050).

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.

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.

The Center for Watershed Sciences authored a technical report, "Montane Meadows in the Sierra Nevada: Changing Hydroclimatic Conditions and Concepts for Vulnerability Assessment" to better prepare the meadows community for ecosystem monitoring and restoration planning under future hydroclimatic conditions.

A new strategy summary report has been released highlighting approaches to restoring and/or protecting 30,000 meadow acres on all lands in the Sierra Nevada.

All-hands, all-lands approach to increasing the pace, scale, and efficacy of meadow restoration and protection throughout the Greater Sierra Nevada. Articulates three overarching strategy approaches, 1) Restore and/or protect meadows to achieve desired conditions; 2) Enhance regulatory and institutional funding capacity and coordination; 3) Increase and diversify institutional and partnership capacity for meadow restoration and/or protection in the greater Sierra.
