Summary

To provide a link to NAS presence and distribution of nonindigenous aquatic species data summarized by HUC 8 geographic units. If you open the attributes of a Hydrologic Unit Code (HUC) feature in this dataset the link found in the NAS_link will take you to a page that lists of all nonindigenous aquatic species that have been reported as present in the selected HUC.

Description

This GIS dataset offers a link to the California portion of the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. The NAS program has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientic reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The goal of the information system is to provide timely, reliable data about the presence and distribution of nonindigenous aquatic species. The NAS database contains locality information for more than 1100 species of vertebrates, invertebrates, and vascular plants. The NAS program provides a continual national repository of distribution information for nonindigenous aquatic species that is used to gain an understanding of aquatic introductions, identify geographic gaps, and access the status of introduced aquatic species nationwide. Data are obtained from many sources including literature, museums, databases, monitoring programs, state and federal agencies, professional communications, online reporting forms, and Aquatic Nuisance Species (ANS) hotline reports. The NAS program defines a nonindigenous aquatic species as a member(s) of a species that enters a body of water of aquatic ecosystem outside of its historic or native range. This includes not only species that arrived from outside of North America but also species native to North America that have been introduced to drainages outside their ranges within the country. Please visit http://nas.er.usgs.gov for more information and to see all of the products and data available through the NAS program.

This particular dataset was produced by Laura Ryley, Pacific States Marine Fisheries Commission, to bring the functionality of the NAS Query by Drainage (8-digit HUC) page ( http://nas.er.usgs.gov/queries/huc8.aspx?state=CA) into the CalFish map viewer.

Use limitations

These data are the result of efforts by many of government and non-government participants in the field, as well as, USGS and various researchers and managers. All publications based on these data should acknowledge all of these efforts. If a publication is based solely on the analysis of NAS data, we suggest that you involve the NAS Program biologists with the writing and/or review of the manuscript. We would also appreciate receiving a reprint or copy of any publications or reports that make use of the NAS data.

Supplemental information
The Hydrologic Unit boundaries displayed in this feature class were derived from the Hydrologic Units layer also found in the CalFish map viewer. Please reference this layers metadata for more information on the creation of these boundary features. Please visit http://nas.er.usgs.gov to see the full range of products and services offered by NAS. The NAS database was originally started with the passage of the Nonindigenous Aquatic Nuisance Species Control and Prevention Act of 1990 (P.L. 101-646). The Act created the Aquatic Nuisance Species Task Force. In turn the Task Force created the NAS program. The goal of the information system is to provide timely, reliable data about the presence and distribution of nonindigenous aquatic species. This disclaimer applies both to individual use of the data and aggregate use of the data. It is strongly recommended that these data are directly acquired from a USGS source, and not indirectly through other sources which may have changed the data in some way. The USGS shall not be held liable for improper or incorrect use of the data retrieved from the NAS data retrieval Internet site. NAS asks that any errors or problems found by the users be reported to us. USGS will make reasonable efforts to correct errors brought to its attention and may update or make changes to the documents provided by this server at any time without notice. However, USGS makes no commitment to update the information contained herein. Because the data in the central database is continually being updated, it is advisable to refresh data retrieved at least once a year after its receipt. These data are the result of efforts by many of government and non-government participants in the field, as well as, USGS and various researchers and managers. All publications based on these data should acknowledge all of these efforts. If a publication is based solely on the analysis of NAS data, we suggest that you involve the NAS Program biologists with the writing and/or review of the manuscript. NAS would also appreciate receiving a reprint or copy of any publications or reports that make use of the NAS data. Finally you can add to the NAS database by reporting sightings of Nonindigenous Aquatic Species to http://nas.er.usgs.gov/SightingReport.aspx
