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.

The Oren Pollak Memorial Research Fund provides student researchers with the funds necessary to pursue their studies and complete important research in grassland science. The Fund was established in 2000 in memory of Dr. Oren Pollak, a leading grassland ecologist, restoration pioneer, and a champion and mentor…

This study addresses a basic problem shared by many riparian conservation projects: parcelization. Having dozens or hundreds of owners along a river can make conserving riparian ecosystems a difficult and expensive enterprise. In the study, the authors present a science-based method for prioritizing the acquisition…
Conservationists should assume that people don’t care about biodiversity. By doing so, they would be especially motivated to figure out what people do care about, and how conservation might be able to align with those interests. Focusing on what it is about nature or its…

Many corvids are renowned as “ecosystem engineers” because they facilitate the long-distance seed dispersal of keystone tree species like oaks. This paper reviews research into various aspects of the relationship between these birds and these trees, and discusses how the relationship can be important –…

Groundwater is intimately connected to surface water, which has profound implications for sustainable water resource management. California has historically overlooked this important interaction and as a consequence, decisions about groundwater extractions have generally failed to address the resulting impacts to aquatic ecosystems such as rivers,…

Bighorn sheep occupy a desert landscape of rugged mountains separated by expansive and very arid valleys. Highways and other development in those valleys fragment habitat and isolate populations from one another. Critical to managing this species is understanding how it was distributed and how its…

This paper describes a program to eradicate an introduced and rapidly increasing population of wild turkeys from an island. It includes a description of the principles important for eradication success and how they were considered and applied in this context. It also represents one of…

The Climate Action Through Conservation project provides a way for local governments, land managers, and planners to understand the links between climate benefits and conservation values and incorporate that knowledge into decisions about land use and land management. This report presents the result: a new…

When non-native ornamental species spread into wild landscapes they can displace natives that have greater wildlife habitat value. Controlling the spread of a non-native species can be difficult when it hybridizes with a native species, because it may no longer be visually distinguishable. This study…

In restoration ecology, understanding how and when species colonize newly created habitat is critically important for assessing progress toward restoration goals. By using camera traps to take a closer look, authors of this study found that riparian corridor restoration can support medium-and large-sized mammalian predators…

Understanding the geographic distribution and long-term dynamics of Sandhill Crane (Grus canadensis) foraging areas and night roost sites is fundamental to their conservation and management. The authors conducted surveys and compiled existing information on the distribution and abundance of these birds at these habitats across…

In 2006, an E. coli outbreak linked to spinach grown in California’s Central Coast region catalyzed reforms in vegetable production. Without evidence, wildlife was targeted as a disease vector and, under industry and governmnet pressure, growers fenced fields, applied wildlife traps and poison, and removed…

Connecting marine, freshwater and terrestrial ecosystems, bar-built estuaries are complex and dynamic coastal confluences that provide a great diversity of habitat and ecosystem services. The wetland habitats of bar-built estuaries are threatened by development, pollution, and climate related changes including diminished streamflows and sea…

In the past, mitigation to address impacts from development have lacked a regional planning perspective resulting in efficient design across a set of sites for a suite of impacts. This paper introduces a tool that uses spatial prioritization to identify optimized mitigation opportunities for solar…

Although agricultural intensification is one of the largest contributors to the loss of global biodiversity, agricultural landscapes can provide valuable habitat for birds. Recognizing this, wildlife professionals are working to promote “wildlife-friendly” farming. In this paper, authors assessed the value to wintering waterbirds of different…

The transformation of California into one of the most productive agricultural and urban landscapes in the world and a growing population have put unprecedented pressure on freshwater habitats, reducing them to a small fraction of their historic extent. Across the state, freshwater-dependent ecosystems have been…
