Paper: “Soil Carbon Pools in California Annual Grassland Ecosystems,” Rangeland Ecology and Management 63 (January 2010):128–136; doi: 10.2111/REM-D-09-00106.1

Research Team: Whendee L. Silver, Rebecca Ryals and Valerie Eviner (Ecosystem Science Division, Department of Environment Science, Policy, and Management, University of California at Berkeley, and Department of Plant Sciences, University of California at Davis)

Findings: When research for MCP began, we wanted to review the existing knowledge on how much carbon (C) is stored in California’s rangeland soils and to see if there were predictable patterns in C storage (i.e., if there were known drivers of patterns across space and time). This paper is a meta-analysis of the literature data on soil C storage in California’s rangelands. Findings indicate that climate is not a good predictor of soil C pools at this scale of resolution and that soil texture (clay content) was a weak correlate of soil C stocks.
