Chronic Wasting Disease (CWD) is a highly contagious neurological disease that affects deer, elk, reindeer, sika deer, and moose. CWD is progressive with symptoms that range from asymptomatic to listlessness, ear droop, altered gait, excessive salivation, teeth grinding, a wasting body composition, and ultimately death. It is thought to be transmitted through body fluids and contaminated soil, food, and water.
First detected in captive deer facilities in the late 1960’s, CWD spread to free ranging, wild herds by 1981. As of August 2024, CWD has been identified in 35 U.S. states and 4 Canadian provinces.
TRIBAL IMPACT
Positive cases of chronic wasting disease are on the rise and studies have shown that CWD can remain in the environment for years. CWD can be detrimental to food security, cultural and spiritual practices, and economic well-being. Surveillance on Tribal lands is crucial for managing the impacts and spread.
NAFWS ACTION
The Native American Fish & Wildlife Society recognizes the threat of CWD to Tribal lands and their citizens. In 2021, NAFWS developed the Chronic Wasting Disease Project to aid Tribal natural resources personnel in managing CWD on Tribal lands. NAFWS staff continues to host informational webinars and in-person trainings at regional and national conferences. NAFWS also continues to update a CWD brochure and laminated extraction sheet for Tribes to use to educate their citizens and staff.
