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...
The California Invasive Plant Council (Cal-IPC) developed a “risk mapping” approach that combines comprehensive distribution maps with maps of current and future suitable range to show where each (invasive) species is likely to spread. The distribution maps are based on a new dataset created through a major campaign to collect expert opinion data from local resource managers across the state. From this dataset, Cal-IPC recently completed risk maps and management recommendations for 43 invasive plant species in the Sierra Nevada. The proposed project will build an online tool for these data. The tool will allow natural resource managers to generate risk maps and summary statistics for areas they select, and to determine...
WHIPPET is an online tool that helps land managers determine which invasive plant populations are the highest priority for eradication. The tool scores populations based on their impact, spread, and feasibility of control. The user can select their region of concern and the species to consider from among the 210 listed in the California Invasive Plant Council Inventory. Beta version to be released fall 2013.
