The vast majority of UAV users, both biologists and hobbyists, do not want to disturb wildlife and will often seek advice from experts. However, in some cases, users may be unaware that their drone operations could be causing considerable and unnecessary disturbance.
Even though an animal might not appear to be disturbed, it could be quite stressed. For example, a bird may choose to remain near a UAV even when stressed because she is incubating an egg or protecting her hatchling. Animal responses vary depending on a variety of factors, including the species, environmental and historical context, and the type of drone and its method of operation.
Studies have shown that drones can be more efficient than traditional approaches to wildlife monitoring and can provide more precise observational data. Accordingly, there has been a considerable increase in the use of UAVs for research purposes. Scientists have now developed a code of best practices intended to help mitigate or alleviate potential disturbance to wildlife related to drone use. The goal is to ensure that UAVs can be a powerful, low-impact ecological survey tool.
- In cases where the evidence is lacking, UAV users should consult with appropriate experts and proceed with an abundance of caution. Further study on the impact of UAVs is also needed.
- UAV users should seek approval when appropriate and explain the anticipated benefit of using UAV technology in their situation.
- Suitably trained UAV operators should comply with all relevant civil aviation rules, which may include restrictions on flying beyond visual line of sight, above a defined altitude, at night, and near people or in the vicinity of important infrastructure and prohibited areas.
- UAVs should be chosen or adapted to minimize disruption, for example, by disguising UAVs as other non-threatening animals.
- UAVs should be launched and recovered from a distance, and a reasonable distance from animals should be maintained at all times during UAV flights.
- Behavioral and physiological stress responses should be measured whenever possible, and UAV flights should be aborted if excessive disturbance is found.
- UAV specifications and flight practices should be detailed accurately and shared in full in published studies, along with any animal responses, accidents, or incidents.
By promoting an awareness of the potential for drones to impact wildlife, users can be more conscious of the potential impacts and utilize the code to ensure their UAV operations are responsible.
Researchers are now conducting studies with the goal of better understanding how different animals respond to UAVs. The results of that work will inform the development of species-specific protocols designed to mitigate or alleviate potential disturbance.
In a time of unprecedented change, drones can assist in understanding, managing, protecting and conserving our planet's biodiversity – if used responsibly and ethically.
