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 estimates of fish populations in the central Sierra Nevada counties specifically Tuolumne, Calaveras, Stanislaus, Mariposa, Mono, and Alpine counties. Information includes the number of individuals per species collected during each of two or three passes with backpack electrofisher(s), section length, section width, date, species sampled, the identifier, UTM coordinates, and (if available) photographs of the site. The species documented include rainbow and brown trout, centrachids such as bluegill and green sunfish, cyprinids such as roach and hitch, as well as other groups (eg. mosquitofish and catfish). Over seventy-five sources of information were used in making the data set including aquatic surveys by several agencies, although most of the information is contained in file reports from the California Department of Fish and Game. Collection dates range from 1979 to 2003. What each record represents Each record represents the collection, identification, and count of one species of fish during one of two or three passes with backpack electrofisher(s), the zone, water, site, UTM coordinates, date, and person or organization responsible for the survey.

This dataset is a subset of the Tuolumne Aquatic Resources Relational Inventory (TARRI) compiled by Brian Quelvog, California Department of Fish and Game. This includes fork lengths and weights for species such as rainbow and brown trout, centrachids such as bluegill and green sunfish, cyprinids such as roach and hitch, as well as other groups (e.g., mosquitofish and catfish). Over seventy-five sources of information were used in making the data set including aquatic surveys by several agencies, although most of the information is contained in file reports from the California Department of Fish and Game. The area of interest includes Tuolumne County and the six surrounding counties: Calaveras, Stanislaus, Merced, Mariposa, Mono, and Alpine. Collection dates range from 1979 to 2003. What each record represents Each record represents the collection, identification, weight, and fork length of each individual of a given species of fish along with the zone, water, site, UTM coordinates, date, and person or organization responsible for the survey.

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.

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for Californias wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (https://www.wildlife.ca.gov/Data/CWHR). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.
