Dabid will be analyzing vegetation composition and soil core data collected from many ranches across California to look for correlations between plant species composition and soil organic carbon. On working lands, vegetation composition has the potential to alter the amount of carbon being introduced into the soil through a mix of physical and biological processes. Studies have shown that land management practices can greatly influence vegetation composition, thus shifting the soil ecology and chemistry. Loss of native plant populations in the state of California have been linked to a decline in total biodiversity in local ecosystems. By comparing soil carbon data to the above ground vegetation composition, Dabid aims to find possible correlations between native plant species abundance and the amount of soil carbon measured at each sampling site. This project will use data collected by Point Blue Conservation Science’s Rangeland Monitoring Network, a collaborative effort between biologists and private land managers to monitor working lands for soil health, vegetation composition, and bird species diversity. Findings from this study may be used to inform land management practices to preserve and promote the ecological health of rangeland ecosystems.
