Anthropogenic impacts upon plant species richness and net primary productivity in California

We assess the importance of anthropogenic land-use, altered productivity, and species invasions for observed productivity–richness relationships in California. To this end, we model net primary productivity (NPP) c. 1750 AD and at present (1982–1999) and map native and exotic vascular...

Patterns of regional and local riparian plant diversity in the California Sacramento - San Joaquin Valley

The widespread degradation of riparian ecosystems requires that we more fully understand patterns of plant diversity at multiple scales to inform restoration and conservation efforts locally and regionally. We analyzed the distribution of riparian plant diversity in California's Sacramento - San...

Climatic and spatial patterns of diversity in the serpentine plants of California

The insular distribution of distinctive substrates, such as outcrops of serpentine rock, may either promote plant diversity by enhancing opportunities for speciation or reduce diversity by increasing rates of extinction. To examine the relationship between diversity and the spatial structure of...

California rivers assessment: Assembling environmental data to characterize California's watersheds

The California Rivers Assessment (CARA) is a computer-based geographic data management system designed to give resource managers, policy-makers, landowners, scientists and interested citizens rapid access to essential information and tools with which to make sound decisions about the...

Earthwatch: Sierra to Sea

The program aims to increase the understanding of the impacts of climate change; participants will measure meadow stability, greenhouse gas emission and absorption, and biodiversity value. By working together with local scientists, nonprofits and communities, we will provide local land managers with insights into management and restoration efforts to help protect California’s valuable water for both humans and wildlife.
