Statewide Risk Mapping for Early Detection



CalWeedMapper enables natural resource managers, scientists and others to create maps and reports of invasive plant distribution, to identify management opportunities in a county, WMA or region, and to maintain up-to-date species distribution data statewide. CalWeedMapper is integrated with the Calflora and Consortium of California Herbaria databases, so that new occurrence data submitted to either informs quad data in CalWeedMapper. For some species, CalWeedMapper also displays maps of suitable range based on species distribution modeling.

CalWeedMapper replaces Cal-IPC’s previous statewide maps (2006-08), which were designed based on surveys of Weed Management Areas. CalWeedMapper represents a major step forward in tracking the distribution of more than 200 invasive plants in California and improving the ability of weed workers to share their data with each other and the public.
