This dataset maps the connectivity and bottlenecks among habitat patches within a six-kilometer ribbon along the United States terrestrial coastline of the Great Lakes. Each pixel represents the relative value that cell contributes to connectivity between and among habitat patches. When aggregated the pixel values produce a map of all possible pathways between habitat patches providing the end user with an understanding of each pathways potential to facilitate or impede species movement. The relative contribution values are determined using the National Land Cover Dataset, where each land use pixel is converted into a value representing its resistance to movement. That is, how easily or difficult movement through that land use type would be for all species. We also provide a map showing the locations within these connected corridors where connectivity is highly constrained which represents bottlenecks in movement across our study area.
