Colorado’s extensive trail networks, attracting millions of visitors annually, serve as critical habitats for ticks. Ticks in Colorado can transmit pathogens that cause diseases such as Rocky Mountain spotted fever and Colorado tick fever. To address this public and veterinary health concern, we are implementing a community science tick surveillance program at trailheads in Northern Colorado.

 *The IRB determined that the proposed activity is not research involving human subjects as defined by DHHS and FDA regulations.


Visit the Colorado Department of Public Health & Environment’s website for more information about ticks and tick-borne diseases in Colorado.

Find a tick on different trails? You can provide the tick via CDPHE’s submission process to help with tick surveillance efforts.

Project members are tick-dragging: "To conduct a tick drag, a researcher uses a 1-square-metre (11 sq ft) strip of white cloth, mounted on a pole that is tied to a length of rope. The researcher drags the cloth behind themselves through terrain that is suspected of harboring ticks, working in a grid-like pattern (Wikipedia)."
