Arlington to Conduct Aerial Drone Survey to Measure Deer Population

Arlington, VA – Arlington County will conduct its second aerial drone deer population survey from March 17-21, 2025 (weather permitting), to document the number and distribution of white-tailed deer. This effort builds on the initial drone study conducted in 2021 and is a key component of the County’s Deer Management Program, which aims to protect natural ecosystems and ensure public safety. 

Why This Survey Matters 

This drone survey is part of Arlington’s ongoing commitment to responsibly manage its natural resources and maintain ecological balance. The data collected will play a pivotal role in the effective implementation of the Deer Management Program, supporting the health and safety of both the environment and the community. Understanding deer population trends will help guide management strategies to address overpopulation and protect native plant communities. 

Survey Details 

• Timing: Drone flights will occur March 17-21, from shortly before sunrise to shortly after sunset. 

• Location: Survey will cover all of Arlington County, except Federal properties. 

• Technology: The survey will use thermal imaging, visual spectrum imagery and GPS to ensure precise data collection. 

• Privacy Protection: The survey primarily detects heat signatures, with low-resolution visual imagery used only for verification. These images are too low in detail to capture identifying features of individuals, to protect privacy. 

• Regulatory Approval: Arlington County has coordinated with the Federal Aviation Administration, U.S. Department of Homeland Security, Transportation Security Administration, Secret Service, Ronald Reagan National Airport, and Arlington County Police Department (ACPD) to ensure compliance with all federal and local regulations. 

Drone Use Restrictions 

Drones are strictly prohibited within 15 miles of Washington, D.C., without special authorization due to federal security restrictions. This survey is an exception as it has received full approval from the FAA and other federal agencies. 

Next Steps & Public Engagement 

Once the data is analyzed, results will be shared on the County’s Deer Management Program webpage. Residents interested in updates can sign up for notifications.
