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.

California, like many regions in the world, needs to plan for emissions reductions and domestic clean energy. Ideally, that would be done in a way that is strategic, not reactionary. Through science-based landscape planning for conservation and energy, the trade-offs between energy development and habitat…

Species will move around the landscape as the climate changes, presenting challenges for traditional conservation strategies like land acquisition. This paper models the cost and total land area that needs to be protected by 2100 to track the changing distribution of 11 focal species of…
Small preserves are difficult to manage, but they can be important for rare plant protection. The article outlines the management challenges faced by small preserves, provides a case study from The San Bernardino Mountains of southern California, and suggests strategies and management recommendations for rare…

A two-page summary of salmon restoration efforts at the Garcia River Forest on the North Cost of California focusing on the reintroduction of wood in streams as a strategy.

Salmon and trout thrive in streams with cool water, low levels of sand and silt, and deep, shaded pools. Intensive forest management in California over the last 150 years led to the removal of these streamside trees, eliminating the cover that salmon depend upon. Restoration…

Understanding how plant invasions occur is vitally important for land managers and conservationists working to enhance biodiversity in California grasslands. While much of the research on this topic has focused on the shifting mosaic of plant species aboveground, this study highlights how understanding the differences…

This paper discusses conservation of the Island Scrub-Jay in the context of novel threats posed by climate change. The authors discuss management actions that could reduce extinction risk—including vaccination, captive propagation, biosecurity measures, and establishing a second free-living population on a neighboring island—and present a…

As the climate warms, changes in ecosystems will impact human communities and livelihoods. This paper, together with a California Energy Commission Scenarios Report of the same name, explores the broad impacts of climate change on ecosystem services and California’s economy. These publications help direct land…

The voluntary carbon market is a new and growing market that is increasingly important to consider in managing forestland. Monitoring, reporting, and verifying carbon stocks and fluxes at a project level is the single largest direct cost of a forest carbon offset project. There are…
Invasive species can have profound effects on island ecosystems. So, too, can their removal. And interactions among species can both help and hinder the attainment of restoration goals. This paper provides a 30 year retrospective review of the multiple eradications that have occurred on Santa…

As West Nile virus invaded the mainland southern California coast in 2003 there were widespread die-offs of certain species of bird. Corvids (e.g., jays, ravens, crows) were especially susceptible. Concerns about the potential impact on Island Scrub-Jays – which are restricted to Santa Cruz Island,…

Concerns about the spread of West Nile virus in North America and the high mortality it causes in corvids have led managers to consider vaccination as a strategy to proactively protect free-ranging Island Scrub-Jays. But, are available vaccines effective? This study tested the efficacy of…

This analysis provides an approach for distilling complex climate and landscape data into actions land managers can take to help plants and animals adapt to a changing climate. Based on historical data, climate projections and landscape attributes like topography, coastal proximity and habitat fragmentation that…

Eradication programs are complex undertakings that require comprehensive multidisciplinary planning and nimble adaptive implementation. This paper discusses the preparation that went into the most intensive feral pig eradication program to date, and highlights how that preparation enabled to project to proceed uninterrupted, despite numerous anticipated…

Tremendous advances over recent decades in eradication of invasive species on islands raise the question whether there are now opportunities to further increase the pace and scale of that work. This paper highlights the increased return on investment that could come via conservationists, scientists, managers,…

Climate change will impact plants and animals across the state, and conservationists are often unaware of the best way to address this threat. While much of the land in the Northern Sierra is public and protected from development, it is still at risk to changes…

While the literature and guidance on traditional conservation planning methods is extensive, there are few case studies on methods for incorporating climate change into conservation planning efforts. This report outlines the methods the Conservancy used to develop strategies to help species adapt in the Mount…

Most assessments of ecological restoration success track a single type of species over a single season. This study explores the limitations of such studies by examining how birds, rodents, bees and beetles responded to restoration along the Sacramento River for up to five years. The authors…
Soils harbor an estimated 1.6 million species. An estimated 1% of the earth’s topsoil is lost each year and in the U.S. over 500 rare soil types are classified as endangered. The biodiversity of soils underpins crucial ecosystem services which support the plants and animals typically targeted…
