Environmental Sensitivity Index (ESI) maps provide a concise summary of coastal resources that are at risk if an oil spill occurs nearby. Many of the resources are biological--including birds, mammals, and plants.
Below you'll find the complete ESI Species List in Excel (.xlsx) and database (.dbf) formats. The DBF-formatted file can be used in Esri software, as well as in numerous other databases, including Microsoft Excel. These versions were updated in February 2015.
Note: The ESI Species List includes all of the species that have ever been mapped on any ESI map. That a species appears in this list is not a guarantee that it was mapped on a given ESI map, even if the species was present in that particular ESI atlas region.
On the front of ESI maps, locations of biological resources are shown with color-coded symbols for localized locations (such as nesting sites) and similarly color-coded polygons for larger areas. On the back of ESI maps and on the GIS data tables, there is detailed information about the species seasonality, concentrations, and breeding activities.
