Invasive Plant Mapping
Mapping invasive plant populations is critical for strategic management and monitoring. It is also essential for effective early detection. Knowing where a plant currently grows is the foundation for knowing where to survey for new occurrences. Cal-IPC supports mapping tools for land managers, and works with regional partners to set landscape-level strategies based on CalWeedMapper.
CalWeedMapper is an online decision-support tool developed by Cal-IPC to help regional partners set effective landscape-level strategies. It shows statewide distribution, spread and management for all invasive plant species on the Cal-IPC Inventory. For any user-selected region, CalWeedMapper recommends species to consider for eradication, surveillance, or containment strategies. CalWeedMapper also includes maps of suitable range for some plants based on climate, with projections for how that range may shift in the future. Go to CalWeedMapper!
WHIPPET is an online tool designed to prioritize invasive plant populations for eradication. The tool allows the user to select an area of interest and a set of invasive plant species to consider. WHIPPET then ranks the populations based on a range of factors, such as its location and estimated cost to control. To use WHIPPET, population mapping data must be in Calflora. Go to WHIPPET!
Calflora is an online database of plant observations. Whether you have a single invasive plant observation or an entire GIS dataset, your data belongs in Calflora where you can use this data in various powerful ways and the information updates CalWeedMapper nightly.Go to Calflora!
Cal-IPC works closely with Calflora to support invasive plant mapping in California. We encourage land managers to submit potential "early detection" observations to Calflora immediately, and to share weed mapping data with Calflora on a regular basis. We actively support Calflora's development of the Weed Manager tool. We also work to integrate California's mapping data with national systems like EDDMapS.Sharing your data online is a way to help us all be more effective!
Ways to submit your data:

- Upload your organization's GIS datasets (instructions)
- Send observations from your smart phone (instructions)
Ways to help close data gaps:
- Confirm mystery populations and update Calflora/CalWeedMapper (instructions)
- Mark "management status" for populations you work on (instructions)
