USGS Aquatic Gap Analysis Program


The Aquatic Gap Program represents the portion of the USGS Gap Analysis Program that focuses on aquatic species found in coastal and inland waters. The goal of the National Aquatic GAP is to evaluate aquatic biological diversity and aquatic habitats using spatial analysis and habitat suitability models to identify gaps in species distribution and work toward more effective conservation prioritization. Our current efforts are focused on modeling the rangewide distribution of fish species which are wide ranging, non-habitat specialist, and of specific interest to our natural resource management agency and conservation partners.
