WHIPPET prioritization tool
Which populations to attack first? WHIPPET 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 the region of concern and the species to consider from among the 210 listed in the California Invasive Plant Council Inventory. It can analyze hundreds of populations of multiple species simultaneously. Default values are built in but there are also options for customization. Users receive results as a spreadsheet and pdf map. GIS is not required but results can be imported into GIS.

Planning regional strategy with CalWeedMapper
Cal-IPC invites you to participate in a process to review and set strategic management priorities for invasive plants in your region. In the last two years many of you helped to build the statewide invasive plant distribution dataset used by CalWeedMapper to identify management priorities – now we’re using this tool to help regional partners design fundable projects.
The goals are to: (1) identify and scope top eradication priorities in order to pursue funding to implement projects in each region, and (2) to identify key surveillance targets to watch for in each region.
With management funding in short supply, it is critical that projects are based on a solid strategy to achieve long-term conservation benefit. This process helps us all move from an “acres treated” mindset to an “acres protected from spread” mindset.
- Regional lists of strategic surveillance and eradication priority species
- Education and outreach information for these species
- The ability to track new occurrence reports of these species in your region
- Collaborative funding opportunities through grant-ready projects detailed in a workplan for these strategic species
Keep posted through your Weed Management Area for meetings in your region. See our regions page to keep tabs on our efforts around the state.
EDRR priorities for Shasta-Trinity NF
The Shasta-Trinity National Forest used the distribution information in CalWeedMapper as a primary source to establish management priorities for the forest. The Shasta-Trinity is the largest forest in California at 2.1 million acres. Much of this area is fragmented with private and other land ownerships, making up an additional 1 million acres that are outside of the management jurisdiction of the Forest Service, but within the outer boundary of the Shasta-Trinity.
Their resulting strategy enables the forest to use an early detection and rapid response approach. In addition, this process identified a small number of eradication targets that represent the low hanging fruit that can be acted on now in an effort to prevent further entrenchment of these species in the landscape.
See a description of their process and priority species in the Shasta-Trinity National Forest Non-Native Invasive Plant Management Priorities report.
This project also spawned coordination and cooperation at various scales throughout the 5 county region of the Shasta Trinity National Forest. Thank you to the USFS, NFF and the CA LCC for support of our regional efforts!
