EIMS SUMMARY REPORT
Entry ID:  1750 Version:  1.0
Title:  AQUATIC/WETLAND SPECIES AT RISK 1996 (IWI VERSION 1.2, 1.3) (IWI) VERSION 1.0
Abstract:  
This data layer provides information about the presence of species at risk in a given watershed. The State agency-based Natural Heritage Network and The Nature Conservancy (TNC) assess the conservation status of plants and animals, and map out the population occurrences of those species at greatest risk of extinction. This indicator represents the number of aquatic or wetland-dependent species documented in a watershed that are classified by the Heritage Network as critically imperiled (identified by TNC as G1), imperiled (G2), or vulnerable (G3), or that are listed under the federal Endangered Species Act (ESA) as threatened or endangered. The presence of rare or endangered species in a watershed is not necessarily an indication of poor watershed conditions. Indeed, it more likely indicates the opposite: in many instances these species persist only in areas of exceptionally high quality habitat. The presence of species at risk in a watershed indicates, however, that these watersheds are especially vulnerable to future water quality or habitat degradation, which could jeopardize the maintenance or recovery of these organisms. Watersheds considered vulnerable because of the presence of species at risk may require special attention to protect or restore water quality in order to maintain these biological values.

Additional Information:  Plans to Improve this Data LayerWorking with U.S. EPA's Office of Information Resources Management, plans are being developed that could improve heritage data consistency among States, reduce data processing backlogs, and create a more readily accessible national element occurrence data set. In the short-term, information could be compiled and mapped for specific groups of organisms (e.g., fish and mussels) to complement the occurrence information available and reduce watershed data gaps on the map.

QUALITY ASSURANCE
Data Use / Constraints:  THE PRESENCE OF AN INDIVIDUAL SPECIES IN A WATERSHED IS BASED ON THE EXISTENCE IN THE HERITAGE DATABASES OF AT LEAST ONE DOCUMENTED OCCURRENCE IN THAT WATERSHED SINCE 1970. FURTHERMORE, OCCURRENCES MUST BE GEO-REFERENCED AT A PRECISION-LEVEL OF AT LEAST ONE-MINUTE LATITUDE/LONGITUDE. THIS MAP INCLUDES ONLY SPECIES THAT MEET THE FOLLOWING TWO CRITERIA FOR STATUS AND HABITAT USE: 1) HERITAGE/CONSERVANCY CONSERVATION STATUS OF CRITICALLY IMPERILED TO VULNERABLE (G1-G3), OR FEDERAL ESA STATUS OF THREATENED OR ENDANGERED; AND 2) DEPENDENT ON AQUATIC OR WETLAND HABITATS BASED ON SELECTION CRITERIA DEVELOPED AS PART OF THE U.S. EPA ENVIRONMENTAL INDICATORS OF WATER QUALITY IN THE UNITED STATES REPORT.NOTES ON INTERPRETING THIS INFORMATIONDATA NEED TO BE MUCH MORE CONSISTENT/MUCH ADDITIONAL DATA NEEDEDSEE COMMENTS FOR ADDTIONAL INFORMATION

5)   The basic locational data underlying this map are developed and stored by the State agency-based Natural Heritage Data Centers. These State data centers document the location of rare and endangered species for use in environmental planning and conservation efforts. Locational data from 48 States were aggregated and combined with conservation status and habitat use information maintained by TNC to develop this map.
