The Lassen and Modoc National Forests are located where the Great Basin, the Sierra Nevada, and the Southern Cascades meet. Other science syntheses have focused on the Cascades and the Sierra Nevada and are relevant to the Lassen and Modoc National Forests, but do not cover the mostly dry ecosystems and species assemblages found in northeastern California. The new publication, Northeastern California plateaus bioregion science synthesis (Gen. Tech. Rep. RMRS-GTR-409), has a northeastern California focus on sagebrush rangeland, dry pine forestland, juniper forests, habitat and wildlife, society, and response to disturbances, particularly those related to climate. This report helps complete the scientific picture that will inform forest plan updates in the Sierra Nevada through the Cascades and help meet the 2012 planning rule requirement for using the best available science.
The Northeastern California Plateaus Bioregion Science Synthesis was prepared by USDA Forest Service scientists within the Western Center for Native Plant Conservation and Restoration Science, including the Pacific Southwest Research Station (PSW) and Rocky Mountain Research Station (RMRS). The Plateaus Synthesis resulted from a specific request made to the Pacific Southwest Regional Forester by local governments to cover ecosystems and topics not discussed in two previous syntheses, Science Synthesis to Support Socioecological Resilience in the Sierra Nevada and Southern Cascade Range and Synthesis of Science to Inform Land Management Within the Northwest Forest Plan Area. All three of these science syntheses gather and summarize the best available scientific information.
The Plateaus Science Synthesis covers five major topic areas that were identified during a workshop with the public: forestland, rangeland, habitat and wildlife, disturbance, and management for sustainability—primarily ecological but also economic and social.
The Northeastern California Plateaus Bioregion Science Synthesis is relevant to other national forests in the western United States with similar habitats. Together with the other two syntheses, this report will provide a foundation for upcoming forest plan modernization in the northwestern U.S. The USDA Forest Service can use these science syntheses to communicate with stakeholders, tribes, and the public about potential management practices.
