The dataset contains a polygon representing the Great Salt Lake Sentinel Landscape (GSLSL) Boundary. The GSLSL was established in 2024 to align interests, maximize resources, and build resilience in military installations, communities, and ecosystems within the Great Salt Lake Basin. The boundary of the GSLSL was created using insight from federal agencies, state and local governments, and non-governmental organizations. The purpose of this dataset is to help current and future partners of the Great Salt Lake Sentinel Landscape spatially understand the area where conservation efforts may align with the goals of the Sentinel Landscape Partnership to best leverage funding opportunities.
