Unmanned aerial vehicles (UAVs) are at the cutting edge of technology being applied in ecological research.

As UAV technology continues to rapidly develop, Vincent et al. (Front Ecol Environ 2015; 13[2]: 74–75) noted that the potential research applications of UAVs are stymied by legislative regulations imposed by government bodies. However, US laws are being revised to reflect differences between UAV and manned aircraft, and new Federal Aviation Administration (FAA) policies in the US will greatly assist ecologists who seek to use UAVs in their research. New FAA policy grants a Certificate of Waiver or Authorization (COA) for UAV applications by registered operators who meet their new criteria (WebTable 1; FAA 2015). This is a breakthrough, given that previous policy required a “Certificate of Authorization” for individual UAV flights. Ecologists, once becoming certified operators, now have an automatic “Certificate of Authorization” for undertaking most UAV operations relevant to conducting science. As a result of the change in policy, UAV laws in the US now more closely resemble the unambiguous and less restrictive UAV laws in Australia (WebTable 1), where Google and Amazon chose to site their drone delivery testing facilities.

Regardless of legislative change, there are ways to incorporate UAVs into research that can avoid some of the issues outlined by Vincent et al. If universities do not want to become registered operators, they can collaborate with industry partners who are registered. We are currently using such an approach in our ecological research. We believe this provides the best starting point for academic institutions to use UAVs for research purposes, without the need for in-house logistical support or expertise to meet legislative requirements.

While few universities have UAV Operators Certificate (UOC) approval in Australia (, 25 academic institutions in the US — as of July 2015 — hold a COA ( Thus, if Vincent et al. worked with a registered industry partner who already had a COA, they could work as close as two nautical miles from the airstrip they describe without the requirement to hold their own COA.

To conduct research within two nautical miles of a registered airstrip still requires a COA, and with good reason. A registered airstrip is marked on official aviation maps for all aircraft, and can be used for emergency landings. The last thing that a pilot in distress needs is to mistake a small UAV in close proximity for a large airplane in the distance. After all, UAV operators typically do not monitor aviation radio frequencies to inform pilots otherwise. It is important for the broader research community to recognize that UAVs are not toys; they are certified aircraft used for commercial purposes, and can pose a serious threat to both people and property when used irresponsibly.

Finally, proposed changes to UAV laws in Australia could relax the requirement of a UOC for remote-piloted aircraft under 2 kg (CASA 2014). As ecologists already undertaking research with UAVs under 2 kg, we are excited about the possibilities that such changes could foster.

Continued positive changes in UAV-relevant legislation globally — together with industry partnerships — should promote the rapid uptake of UAVs as important tools in conducting ecological field-based studies.

    Hi Euan, I couldn’t down the full text of UAV article on your site (had no trouble with the feral cat management paper). I have suggested looking at UAVs in combo with IR cameras (as used by European farmers to isolate fawns in new-cut hay) to John Read in South Aust. a couple of years ago, when discussing feral cat device ideas. Cheers, Peter

    Hi Peter, Colin, we’ve updated the post with the full letter plus downloadable PDF. Apologies, this wasn’t available earlier.
