CalWeedMapper is an online tool that provides maps of 210 invasive plants from the California Invasive Plant Inventory, as well as maps of suitable range in 2010 and 2050 climate for 79 species. CalWeedMapper also provides users the ability to generate reports of recommended eradication, surveillance, and containment targets based on the user’s selected area.
Workshop on Climate Smart Land Management (with focus on invasive plants) at Cal-IPC Symposium, October 2013.
Maps showing projected future range of 79 invasive plants, based on current (2010) and future (2050) climate. Models used an ensemble of 17 Global Circulation Models from PRISM and were run using (open source) Maxent software. Maps are posted on CalWeedMapper (https://calweedmapper.cal-ipc.org/maps/).
Strategic plans list eradication and surveillance species for a multi-county region, as agreed upon by local land managers. Most species are based on the Cal-IPC Inventory and maps in CalWeedMapper. The purpose of these plans is to enable land managers to apply for grants for coordinated projects in their region. The emphasis is on species that can be eradicated within five years and species that are just outside the region and have a high probability of invading. The plans are available on the CalWeedMapper website at https://calweedmapper.cal-ipc.org/regions/.
The California Invasive Plant Council (Cal-IPC) worked with dozens of partner organizations to map invasive plants statewide and to build an online decision-support tool, CalWeedMapper, to use the data. Cal-IPC has used the tool to design landscape-level projects with regional partners, and has been successful in securing funds for on-the-ground implementation of high-priority projects. CalWeedMapper provides spatial information that serves as the foundation for selecting priorities and demonstrating clear rationale to funders. For many plants, the tool shows suitable range, both current and projected for mid-century, which allows climate change to be incorporated into prioritization. By viewing distributions at...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
