Monitoring of vegetation in Everglades and Dry Tortugas National Parks includes maintaining accurate lists of plant species in the parks, tracking of threatened and endangered plants, and monitoring of natural vegetation communities. Current priorities for Everglades National Park include updating rare plant distribution and abundance information using GPS receivers to collect accurate location data, mapping park vegetation communities, and monitoring the vegetation of Taylor Slough to track changes in vegetation resulting from water management projects. Vegetation monitoring in Dry Tortugas National Park focuses on tracking recovery of plant communities on Loggerhead Key following exotic plant removal and mapping the vegetation communities of the park's islands.
