Do Drones Create Undue Stress in the Animals They Track?

Drone Vs. Wild

Unmanned aerial vehicles (or UAVS, better known as drones) have complex interactions with the animals they monitor. Though scientists use drones to protect animals from poachers and obtain data on threatened species, evidence suggests these flying devices take an unseen toll on the creatures they track. YouTube even boasts a multitude of videos that show chimps, eagles, lions, and rams viciously attacking UAVs. So what’s going on when drone meets beast?

In the first study of its kind, scientists measured Minnesota black bears’ physiological responses to UAVs, which flew overhead 17 times. Data from sensors previously implanted in the bears revealed that in nearly all trials the animals’ heart rates significantly increased, though few behavioral reactions were noted. In the most extreme case, sensors recorded a 400% spike in one bear’s heart rate, from 39 to 162 beats per minute. University of Minnesota study leader Mark Ditmer found the results somewhat surprising, as bears in this region commonly hear loud noises from farm equipment and nearby traffic. “We thought they’d seen everything,” he said. Still, “Drones have different sounds and different capabilities. They can fly under the forest canopy, they can get very close, and even follow an individual.”

David Wilkie, the Wildlife Conservation Society’s director of Conservation Support, hesitated to read too much into the findings without further research on drone-wildlife interactions, noting: “Heart rate is really an indication of arousal, a natural reaction. All animals get aroused when there’s an unfamiliar sound. It’s about vigilance, not necessarily stress.” He called for a study to measure the amount of stress hormone cortisol found in animals’ feces after UAV flight trials. Ditmer conceded that, though wild species may habituate to UAVs just as they have to highways and other manmade noises, the potentially chronic stress from constant close-up drones could have unknown consequences, even impacting bears’ success in reproducing and finding food, as well as weakening their immune systems. “If you have an endangered species or animals sensitive to human interference, we could push them beyond a threshold,” he said.

More Good Than Harm?

The key may be to test individual species’ reactions to UAVs before implementing long-term drone surveillance on them, ensuring the benefits (e.g. protecting them from poachers and obtaining insightful data) to that group always outweigh any stress inflicted. In science journal Current Biology, Australian researchers Jarrod Hodgson and Lian Pin Koh agree that “It is likely that animal responses vary depending on a variety of factors, including the species, environmental and historical context, and the type of UAV and its method of operation.” The duo outline some best practice guidelines they hope will both public and private sectors will implement to minimize stressful drone-animal interactions. For instance, Hodgson and Koh recommend that researchers choose drone models that are unobtrusive and even camouflaged, that they consider obtaining data via satellite images or manned aircraft before deploying drones, and that any negative animal responses should be shared in published studies. With these suggestions, they seek  to define drones as “a powerful, low-impact ecological survey tool” that can harvest key data on threatened populations within acting in ways that could threaten them further.

Clearly-defined legislation can serve to insulate wild animals from drone hobbyists, who may have no qualms about flying drones right up to wildlife for the sake of a good photo. Currently, Canadian law bans all drones within 150 meters of wild animals, while the US National Park Service prohibits drones from flying over protected land so that animal inhabitants will remain undisturbed. Wilkie noted that, after lawmakers and researchers lay out what constitutes appropriate drone behavior around wild animals, UAVS will  have “enormous potential that we’ve barely begun to tap,” and Hodgson and Koh too are optimistic. “In our experience, the vast majority of UAV users, both biologists and hobbyists, do not want to disturb wildlife and will often seek advice from experts,” Hodgson said. “By promoting an awareness of the potential for UAVs to impact wildlife, we hope that users will be more conscious of the potential impacts and utilize the code to ensure their UAV operations are responsible.” If their consequences on animal physiology are properly researched and shared amongst the scientific community, who knows the vitally important data that drones could secure on threatened wildlife species, even possibly helping them escape extinction?

A Year in Review: Seven Stories that Highlight Hope for Conservation in 2016

Channel Islands fox rebound

The Channel Islands, eight islands off the coast of Southern California, house more of their adorable cat-size foxes (found nowhere else on earth) than ever in recent history. Thanks to conservation efforts including captive breeding of the foxes and relocation of predatory eagles, the population was recently removed from the endangered species list.

Chernobyl wildlife boom

Though Ukraine’s Chernobyl nuclear power plant exploded over 30 years ago, it has left behind a wasteland that most scientists thought would remain barren for years to come. However, in 2014 University of Georgia researchers left dozens of cameras in a heavily forested area of Chernobyl’s 1600-square-mile Exclusion Zone and saw that boars, wolves, foxes, raccoon dogs and many more species had reclaimed the land as their own. “It’s basically an incredibly large sanctuary” for animals, said one researcher of the follow-up study and accompanying photos which were published this year.

Robotic animals used to trick poachers

US authorities have come up with an unexpected but highly successful method to catch poachers: placing remote-controlled robotic animals like deer, bear, and moose in illegal hunting hubs and apprehending those foolhardy enough to shoot at them.

Peanut butter and drones provide a creative way to help adorable ferrets

Native to the US, beautiful black-footed ferrets currently hold the spot of North America’s most endangered species, due in large part to a plague killing prairie dogs, their main source of food. This year the federal government began testing a unique and tasty solution that could drive the ferrets’ population to healthy numbers: using drones to drop peanut butter-flavored pellets laced with plague vaccine on unsuspecting prairie dogs (about 60-90% of prairie dogs fell for the trick in recent tests), helping their populations recover enough to restore a balanced ecosystem to the American grasslands where the dogs and ferrets reside.

Full-time Hedgehog Officer for British Town

Officials in Ipswich, a village on the eastern coast of the UK, have recently noted declines in typically high hedgehog populations, so a local wildlife organization created the post of “Hedgehog Officer”, tasking the British woman who beat around 150 applicants with conserving this adorable local creature.

Jaguars settling in Arizona

Jaguars claimed much of the western US as their own before being completely hunted to death, but 2016 gave two positive signs that some of the creatures may have migrated from northern Mexico into the Arizona desert. A few months following the appearance of a gorgeous male, caught on camera and nicknamed El Jefe, a second male cat was photographed prowling around an Arizona army installation. Though Arizona wildlife officials dampened some excitement with the revelation that the closest breeding population is 130 miles south, the presence of these cats brings hope that more may eventually find their way to their old stomping grounds in the US.

Strong protections for some of world’s most endangered animals

The 2016 Convention on International Trade in Endangered Species (CITES) concluded by creating tough new regulations against killing and trading endangered animals currently vulnerable to poachers, including African gray parrots, pangolins, and manta rays.

Threatened Texas Mussel May Spark Conflict Over Contested Waterways

The US Fish and Wildlife Service recently proposed the Texas hornshell mussel be classified as endangered, opening a new avenue for conflict over already highly-contested water systems throughout the state. The mussel is one of a dozen the USFWS is examining for endangered list inclusion, and if chosen, the mussel’s freshwater river habitats would be specially protected from heavy human usage.

If the species is listed, other mussels may be included as well. “This move provides insight into their thinking” on the remaining species, said Charles Randklev, a mussel expert at Texas A&M University’s Institute for Renewable Natural Resources. The hornshell “warrants some level of protection based on the data I’ve seen,” he said, “and some of the species are not faring as well as the hornshell.” These others include mussel species living in Central Texas’  Colorado, Guadalupe and Brazos river basins in Central Texas, such as the false spike and the Texas pimpleback.

Human activity is to blame for disruption of the mussels’ populations, says the USFWS, through creation of dams and increasingly poor water quality that hurt the Texas hornshell and other Southwest freshwater mussels. “The waterways they call home are being altered and impacted by declining water quality and quantity,” Benjamin Tuggle, the USFWS’s Southwest regional director, reported. “Declining freshwater mussel populations are signs of an unhealthy aquatic system, which has negative implications for the fish, wildlife and communities that depend upon those rivers and streams.”

However, protections bestowed in the best interests of the mussels will have vast impacts on the already much-disputed distribution of water to industries, farmers, and Texas’ growing cities by state river authorities. “With increased human demand, the question is how that affects stream flows,” Randklev said.

Despite Tuggle’s statement that he hopes to work closely with landowners “to benefit both the species and communities that rely upon those flowing waters”, a legal fight between federal and state officials seems likely if the mussel is listed. The state comptroller’s office has commissioned research into how increased habitat protections would harm Texas’ economy. “We’re still examining the proposal, and we also need to look at the species status assessment report,” comptroller spokesman Chris Bryan said.

Once plentiful (and a staple of indigenous peoples), the Texas hornshell mussel is a filter feeder that can grow up to 4 inches long and live around 20 years. This species has vastly declined within the past few decades, according to the Federal Register. The mussels are technically edible but are not considered safe to eat where water is polluted. The mollusk habitates within the Rio Grande downstream from Big Bend National Park and Laredo, as well as in the Pecos and the Devils rivers in Val Verde County.

The Nature Conservancy and Texas Parks and Wildlife Department have already begun efforts to maintain this and other threatened river species, taking measures to reduce sediment and contaminants on protected land near the Devils River watershed. In addition, Lower Colorado River Authority and the Guadalupe-Blanco River Authority officials are monitoring the addition of any Texas waterway species to the endangered list. “At this point it’s premature to say whether or how future listings may impact the lower Colorado River basin,” LCRA spokeswoman Clara Tuma said. Only time will tell how this potential conflict will play out if the mussel is listed.

The Fish and Wildlife Service will be taking comments from the public regarding the proposed endangered species listing of the Texas hornshell mussel until Oct. 11 before they come to a decision.
