Environmental Sensitivity Index (ESI) data characterize the marine and coastal environments and wildlife based on sensitivity to spilled oil. Coastal species that are listed as threatened, endangered, or as a species of concern, by either federal or state governments, are a primary focus. A subset of the ESI data, the ESI Threatened and Endangered Species (T&E) databases focus strictly on these species. Species are mapped individually. In addition to showing spatial extent, each species polygon, point, or line has attributes describing abundance, seasonality, threatened/endangered status, and life history. Both the state and federal status is provided, along with the year the ESI data were published. This is important, as the status of a species can vary over time. As always, the ESI data are a snapshot in time. The biology layers focus on threatened/endangered status, areas of high concentration, and areas where sensitive life stages may occur. Supporting data tables provide species-/location-specific abundance, seasonality, status, life history, and source information. Human-use resources mapped include managed areas (parks, refuges, critical habitats, etc.) and resources that may be impacted by oiling and/or cleanup, such as beaches, archaeological sites, marinas, etc. ESIs are available for the majority of the US coastline, as well as the US territories. ESI data are available as PDF maps, as well as in a variety of GIS formats. For more information, go to http://response.restoration.noaa.gov/esi .

This data set comprises the Environmental Sensitivity Index (ESI) and Reach Sensitivity Index (RSI) data for Puerto Rico. ESI data characterize estuarine environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. Most rivers and streams can be readily subdivided into clear-cut segments, or reaches (RSI), that have very distinct and uniform characteristics within that reach of the stream. The definition of reach type is usually based on whatever the intended use of the reach classification might be. In this project, stream reaches are defined as those segments where similar spill-response modes and potential ecological and/or socioeconomic impacts from the spill are to be anticipated. However defined, the boundary of the reach is usually marked by an abrupt change in the morphology of the stream, a change commonly, but not always, brought about by an alteration in the stream's gradient. This data set contains sensitive biological resource polygonal data for invertebrates.

These ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. These data were released as a DVD product which consolidated the original California ESI atlases that were also previously archived at the NODC under the following accessions; Northern California, 2000 (accession number 0013175), Central California, 2006 (accession number 0013176), San Francisco Bay, 1998 (accession number 0013224), and Southern California, 2000 (accession number 0013225).

ESI MAPS SHOULD NOT BE USED FOR NAVIGATIONAL PURPOSES. Source data used in the development of these regional atlases range from 1959 to 2009 with much of the data dated from the 1980s, 1990s, to 2009. Source data dates are extensively documented in the dataset metadata and include the following Central California, data range 2005-07, compiled 2007, Northern California data range 1959-2007, compiled 2007, San Francisco data range 1976-1998, compiled 1998, and Southern California data range 1982-2009, compiled 2008-2010.

This atlas update adds data formats to those originally released to accommodate new technologies of digital mapping. The underlying data have not been updated since the atlas publication dates shown. Each ESI atlas listed is provided in a variety of GIS formats, including a personal Geodatabase for use with the ESRI ArcGIS product line. An .mxd file, created in ArcMap 9.3 is also included. This mapping document provides links to all of the data tables and symbolization of the layers using the standardized ESI colors and hatch patterns. Layer files are also supplied. These, together with the associated geodatabase, can be used in other mapping projects to define the symbology and links established in the original ESI .mxd file.

There are also PDF files of the printed maps. All of these are now formatted to have the back of the maps a part of the same document as the map itself. This eases printing and sharing of the maps and helps to assure that the maps are not distributed without the supporting data. Links from the index map will route the user to the relevant map page. The GIS data are also provided in ARC Export .e00 format, as shape files with an ArcView 3.x project and in MOSS format. Database files are included in text and .e00 format. Each area directory contains a readme file which shows the area of coverage and gives a bit more description of the various file formats included.
