What Are Common Health Issues in Blacktail Deer Populations?

Chronic Wasting Disease

Chronic wasting disease (CWD) is a significant concern in Washington blacktail deer populations. It’s a fatal neurological disorder affecting deer, elk, and moose, caused by a misfolded protein called a prion. The disease was first detected in Washington in 2018 and has since been found in multiple counties. To manage CWD, the Washington Department of Fish and Wildlife (WDFW) has implemented a CWD response plan, which includes mandatory testing of harvested deer, education and outreach, and habitat management.

Parasites and Other Health Issues

In addition to CWD, Washington blacktail deer are also susceptible to other health issues such as ticks, liver flukes, and tuberculosis. Ticks can transmit diseases like anaplasmosis and ehrlichiosis, while liver flukes can cause significant mortality in deer. Tuberculosis, caused by the bacterium Mycobacterium bovis, has also been detected in Washington deer. To mitigate these issues, hunters and the public can help by reporting any deer with unusual symptoms, participating in CWD testing, and practicing good hygiene when handling deer.

Management Efforts

The WDFW and other partners are working to manage CWD and other health issues in Washington blacktail deer populations. This includes conducting research on CWD transmission and management, implementing regulations to reduce the risk of disease spread, and educating the public on best practices for handling and testing deer. Hunters can also play a critical role in managing CWD by reporting all deer they harvest and participating in CWD testing. By working together, we can help protect the health and well-being of Washington’s blacktail deer populations.
