A third of California is privately-owned forestland, woodland or grassland. From redwood forests on the north coast to oak savannas in the foothills, these “working wildlands” harbor native plants and animals and natural resources that shape California’s cultural and economic identity. The agricultural goods produced in these landscapes feed into a global market – from beef and dairy to building materials. Rangelands also help recharge groundwater. Healthy forests enhance water quality.

Harvest practices that are unsustainable, however, or conversion of these landscapes to more intensive land uses, can degrade habitats and reduce the flow of important benefits to people.

Working wildlands are what keep California stitched together ecologically. Their continued economic viability is key to the persistence of the ecological benefits they provide. Conservancy scientists work to figure out how to protect and enhance the function of these landscapes – as a critical network for nature.

Historic and Recent Winter Sandhill Crane Distribution in California

Gary L. Ivey, Caroline P. Herziger, David A. Hardt, Gregory H. Golet

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…

Carbon Implications of Fuel Reduction and Ecological Restoration Treatments in Sierra Nevada Forests

Derek Young

A century of fire suppression has dramatically altered the structure and composition of western U.S. forests. When dense, fire-suppressed forests experience wildfire, they often burn severely. To reduce the risk of these wildfires and reduce carbon release to the atmosphere, both critical for climate change…

Whither the Rangeland?: Protection and Conversion of California’s Rangeland Ecosystems

Cameron DR, Marty J, Holland RF

This study assesses the amount of rangeland conversion between 1984 and 2008 in California. The researchers analyzed data from the California Farmland Mapping and Monitoring Program to see where conversion has occurred and what land uses have replaced rangelands. The degree to which rangelands were protected…

Economic costs of achieving current conservation goals in the future as climate changes

M. Rebecca Shaw, Kirk Klausmeyer, D. Richard Cameron, Jason MacKenzie, Patrick Roehrdanz

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…

Saving Salmon One Log at a Time

The Nature Conservancy, Jennifer Carah

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…

The use of airborne laser scanning to develop a pixel-based stratification for a verified carbon offset project

Jordan Golinkoff, Mark Hanus, Jennifer Carah

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…

Cattle grazing can maintain diversity of vernal pool grasslands

Marty, Jaymee T.

Livestock grazing in the American West often conjures up images of cattle degrading riparian areas or spreading weeds throughout desert rangeland. But cattle grazing does not always or necessarily harm biodiversity. In areas where native herbivores have been eliminated, livestock grazing may replicate ecological disturbance…
