How has this Project Benefited Invasive Species Management Efforts at Your Station? We have several contractors working on large scale exotic removal projects. The WIMS project has benefited the contractors with maps to locate their infestations. Furthermore, re-treatment is going to be very important to keep the restored areas exotic free. The WIMS tracking system will help us re-locate the treated areas for re-treatment.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
Although WIMS is great for keeping track of exotics, it is a very hard tool to use in South Florida habitats with such dense canopies. In order to maximize efficiency in the field while waiting for a GPS signal, a recommendation would be to bring exotic treatment equipment for a two-fold approach during "mapping" days.
