Invasive Plant Mapping

The Invasive Spartina Project uses aerial photography and GIS to monitor treatment of cordgrass in San Francisco Bay.

Mapping the distribution of invasive plant populations is a critical task in land management. Regardless of size, organizations rely on maps to set strategic priorities and monitor the effects of treatments over time.

Cal-IPC is working to support the mapping needs of weed workers in several ways. Our field courses help weed workers strengthen their mapping skills. At a statewide level, we are working with partners to develop a system for aggregating management data. Currently we recommend that land managers with large datasets upload their information to the California Department of Fish & Game's BIOS viewer and their metadata to the CERES catalog. Finally, through our risk mapping efforts, we provide baseline data in support of regional early detection strategies.
