Invasive Plant Mapping

Mapping the distribution of invasive plant populations—as well as important resources to be protected—is a critical task in land management. Regardless of size, organizations rely on mapping to set strategic priorities and monitor the effects of treatments over time.

For planning landscape-scale strategy, which includes the early detection of invasive plants expanding their range, it is important to aggregate datasets from multiple jurisdictions. Cal-IPCis works with partners to coordinate statewide aggregation of invasive plant mapping datasets through the California Invasive Plant Mapping Data Consortium. We encourage all organizations to post their datasets to the California Department of Fish & Game's BIOS viewer and their metadata to the CERES catalog.

Cal-IPC has surveyed county Weed Management Areas to create coarse statewide distributions maps of some of the species listed in our inventory.

Mapping Resources

California Invasive Plant Mapping Catalog - A new resource for compiling spatial datasets and metadata on invasive plants from California. Plans include an image gallery of maps.

California Weed Mapping Handbook - Contains background on mapping strategies, and data standards adapted from national standards developed by the National Association of Weed Management Areas.

Aerial imagery - California will soon have free 1-meter color coverage statewide.

Southwest Weed Mapping Project - Includes California desert.

Other State Mapping Projects

Weed Information Management System (WIMS) - Mapping database system for GPS/GIS integration developed by The Nature Conservancy and others.

The California Spatial Information Library (CASIL) - The first place to look for California GIS layers.

US Geological Survey - Recently produced 1-meter coverage statewide.
