Summary

This dataset highlights the geographic distribution of deer harvested and sampled for CWD across various hunt zones. By mapping the locations of CWD surveillance activities, this layer offers insights into the prevalence and distribution of CWD within specific regions, aiding in targeted monitoring and management strategies. The California Department of Fish and Wildlife (CDFW) conducts surveillance for Chronic Wasting Disease (CWD) in deer, elk, and other cervids to monitor and manage its presence within the state's wildlife populations since 1999. Surveillance methods include targeted testing of harvested animals, monitoring of roadkill, and mandatory reporting of sick or unusual-looking animals. Updates will be uploaded as soon as they are available. Please note, data from early years were not standardized as they are now.

Description

This compilation of layers provides a comprehensive view of CWD-related activities, facilitating informed decision-making and strategic planning for wildlife management and disease prevention efforts. To date, there has not yet been any cases of CWD detected in California and surveillance data will be updated regularly. For the latest information, please visit https://wildlife.ca.gov/CWD .

This data is associated with the following datasets: Chronic Wasting Disease Sampling Stations - 2023 - CDFW [ds3154], Participating Meat Processors and Taxidermists - CDFW [ds3155], Approved Deer Carcass Disposal Sites - CDFW [ds3156], Chronic Wasting Disease Sampling Stations - 2024 - CDFW [ds3182], Chronic Wasting Disease Positive Detections - 2024 - CDFW [ds3183], Participating Meat Processors and Taxidermists - 2024 - CDFW [ds3188]).

Field Result
Alias Result
Field description
The result of the test either Negative, Positive, or Pending. Pending to be updated as soon as results are in. No Positives detected to date.

Alias Species
Field description
Species of cervid tested collapsed down into Native Deer (Black tail and mule deer), Native Elk, and Foreign Deer (deer or fawns that were culled or random species or incidences that occurred in California).

Alias Sample Type
Field description
How the sample was obtained i.e. Hunter Harvest, Roadkill, Clinical Suspect, and All other Mortality.


Field Year
Alias Year
Field description
The year the sample is tested is extracted from the "Sample Date". Due to delayed testing the "Year" column may be manually changed to best reflect the year we want to include it for. For example if we received a sample from 2/24/24 but we want to include it in the 2023 surveillance because someone was holding the sample for us, then we would change the "Year" column to "2023" to fit it into the 2023 sampling year.
