The USGS is offering a funding opportunity to a CESU partner for research in the following area: detecting plant species habitat to inform management. The research will be used to investigate phenology informed detection models, model transferability across broad regions, analyze spatial patterns of model uncertainty, and optimize the development and delivery of model results to practitioners charged with the management of species. Being able to detect invasive species and habitats helps to prevent the spread of, eradicate or control invasive species by helping practitioners know what species are problematic where. Thus, the research help make land management agencies work more efficient.Many longstanding challenges remain regarding detection of plant species across broad geographic ext...
