We identify issues and uncertainties that pose obstacles to conservation and then—in collaboration with internal and external colleagues—develop science products that help overcome those obstacles.

Large-scale ecosystem restoration projects seldom undergo comprehensive evaluation to determine project effectiveness. Consequently, there are missed opportunities for learning and strategy refinement. In their synthesis of 36 ecological indicators of Sacramento River riparian restoration, the authors found steady progress in the restoration of riparian habitats and…

When members of a single species display very different behavioral patterns it can present a helpful model for ecological study. This paper examines two breeding populations of a songbird species: one population is mostly sedentary year-round and breeds on the Channel Islands of California; the…

Coastal southern California has long been the focus of regional conservation planning efforts. Decades ago – and prior to today’s heightened awareness of the magnitude of the likely impacts climate change – reserve designs were established with the intent of protecting the region’s very diverse…

As an essential component of food security, agricultural landscapes must play a role in conservation efforts because they occupy large areas of land, are adjacent to critical habitat, and both depend on and provide ecosystem services. Winegrapes are a high-value specialty crop that can both…

The Island Scrub-Jay is the only island restricted bird species in the continental U.S. This study presents findings of a comprehensive breeding ecology study, aimed at elucidating demographic parameters and natural history information needed for conservation management.

The Western San Joaquin Valley Least Conflict Solar Energy Assessment characterizes the land use constraints and opportunities associated with siting solar energy facilities in the Western San Joaquin Valley (WSJV). Because the San Joaquin Valley currently has no official process to develop a conservation and…

A Conservancy analysis of the western Mojave Desert identified where human activities had degraded the conservation value of lands making them potentially low impact locations for development of solar facilities. In this assessment authors applied that same approach in the Western San Joaquin Valley—an area with…
The Southwestern California Climate Report provides 50-year climate scenarios and plant species distribution forecasts to help inform conservation priorities in southwestern California. Spatial data of mid-21st century habitat suitability (refugia, stress, expansion) for 106 native plant species are available here.

This study evaluated the existing network of conservation lands in California to determine the extent to which it includes landscape features that may be especially important for biodiversity conservation in the context of climate change. The authors found that past conservation action has created an…

This paper discusses the 2006 outbreak of toxic foodborne E. coli and its impact on wildlife. The authors explain how farming practices for food safety that target wildlife can damage ecosystems but may not actually improve the safety of the food supply and how high…
This webmap is a product of The Nature Conservancy’s 2013 Western San Joaquin Valley (WSJV) Least Conflict Solar Energy Assessment which characterizes the land use and conservation constraints and opportunities associated with siting solar energy facilities in the WSJV in California. This approach identified areas with high…

Floodplains often are managed both for agriculture and as habitat for native species. On the Sacramento River, farmers have expressed concern that natural areas may be sources of pests to adjoining farmlands, generating opposition to riparian restoration. This study examined this question by studying small…

Island archipelagos can provide useful opportunities for comparative studies in ecology. In this paper, for example, breeding ecology of a songbird was studied on two of the California Channel Islands, which share many environmental attributes but differ in ways that elicit different behavioral responses in…

The Island Scrub-Jay occurs only on 250 km2 Santa Cruz Island. This study combined an intensive, short-term field survey with novel statistical modeling to generate estimates of population abundance, and to characterize its habitat and distribution across its global range.

This paper compares the efficacy of different monitoring methods for estimating distribution, abundance, and population growth of the endangered giant kangaroo rat to determine the best practices for monitoring. Expert rapid assessment of sites performed nearly as well as trapping in determining range extent, while…

Industrial-scale renewable energy generation facilities can have sizable footprints and therefore significant impact on the conservation values of a landscape. This assessment focused on a region experiencing intense development pressure, the western Mojave Desert, to highlight how facilities could be sited to have lower impact…
