The loss or decline of culturally significant plants is a major concern for many tribal managers. Culturally significant plants are essential to many aspects of life for tribal members, including medicine, ceremonial practices, and traditional food dishes. In many parts of the U.S., droughts, floods, and changes in the timing of frost events are stressing these plants and in some cases have led to decreases in their areas of suitable habitat or a reduction in their resistance to disease. The goal of this project is to hold a research symposium that will bring together tribal resource managers and scientists from a range of disciplines in the South Central region to identify which culturally significant species...
The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.

Invasive plants are a major land management problem in the Western U.S. Cheatgrass (Bromus tectorum) is the most prominent and problematic invader in cold deserts, with negative effects on rangeland fire patterns, wildlife habitats, and forage/vegetation. Red brome (B. madritensis) is an invader in the Mojave Desert, and can similarly introduce a new fire patterns to sensitive warm desert scrub. These invasions often cause management agencies to incur high costs for prevention, control, restoration, and fire responses. Control and prevention of invasive species is challenging because the risk of invasive plants becoming abundant depends on existing plant communities, climate and weather, land use, and fire history....

As the predicted impacts of climate change are becoming more apparent, natural resource managers are faced with the task of developing climate adaptation plans. These managers need state-of-the-art, scientifically based information upon which to base these management plans and decisions consistently across California and the Great Basin. This project applies historical, current, and projected climate data to a regional water model to examine water availability, biodiversity, and conservation. Analysis of this climate and hydrology data is expected to help managers understand areas in the region and landscape where the effects of climate change are expected to be the most profound. The study also addresses how the...
