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.

The data provided is from a database known as Can-NEMO (California Non-native Estuarine and marine Organisms) database. The Cal-NEMO databaseincludes comprehensive and user-friendly information on established non-native invertebrates and algae in the marine and estuarine waters of California. A collaboration between Office of Spill Prevention and Response (OSPR) and the Smithsonian Environmental Research Center (SERC), Cal-NEMO is a portal of the National Estuarine and Marine Exotic Species Information System (NEMESIS).Cal-NEMO replaces CANOD, OSPR''s inventory of non-native species in California. Improvements include images and descriptions for identification, maps of global distributions, and information about species ecology and impacts. It is a long-term, dynamic database that we will continue to update as new species are discovered and new research becomes available.The data provided from Cal-NEMO to BIOS includes the introduced species name and location, date observed, and habitats observed.Cal-NEMOincludes species lists and other associated information for both non-native and native coastal aquatic species in California. New records are being added continually, and existing records are frequently updated and modified as new information becomes available. Cal-NEMOis an accumulation of literature review, data collected by other entities, and OSPR field surveys. OSPR began surveying in 2000 and continues to monitor for new introductions. Records before the year 2000 are from literature review and surveys by other entities.

This dataset is a subset of the Tuolumne Aquatic Resources Relational Inventory (TARRI) compiled by Brian Quelvog, California Department of Fish and Game. The database focuses on fish, amphibians, insects, crustacean, and other invertebrates, and includes hydrologic information associated with collection sites in inland waterways located in Tuolumne County and the six surrounding counties (Calaveras, Stanislaus, Merced, Mariposa, Mono, and Alpine). Over seventy-five sources of information were used to develop the dataset including aquatic surveys by several agencies, file reports from the California Department of Fish and Game, personal communications, and research articles as well as museum records from institutions such as the California Academy of Sciences. Collection dates for some data are historical (back to 1889), but the majority range from 1979 to 2003. What each record represents Each record represents the collection, identification, and cataloging of one or more specimens of the given taxon under the location, time, and habitat conditions listed in the record.
