The resurgence of grizzly bears in eastern Montana, a testament to dedicated conservation efforts, presents a unique challenge as human settlements increasingly encroach upon their historical habitats. In 2017, recognizing this dynamic, the state of Montana appointed Wesley Sarmento as its inaugural prairie-based grizzly manager. For approximately seven years, Sarmento dedicated himself to navigating the complex intersection of recovering bear populations and expanding human development. His mission was to proactively mitigate potential conflicts, ensuring the safety of both the threatened grizzly bears, still listed under the Endangered Species Act, and the growing human communities. Operating from Conrad, a town of just 2,553 residents, Sarmento effectively served as a frontline operative, a wildlife first responder tasked with de-escalating volatile situations. His tenure was not without peril; he himself experienced close calls, underscoring the inherent risks of his profession. It was this very danger that propelled him to explore and adopt advanced technologies, specifically drones, to enhance the effectiveness and safety of his work before he transitioned to pursue a PhD.

Sarmento’s journey into bear management began unexpectedly during his research on mountain goats within the majestic confines of Glacier National Park. His initial foray into understanding bear behavior was as unconventional as it was immersive. To gain insight into how mountain goats reacted to the presence of their apex predator, Sarmento adopted a rather unique research method: for over three years, he donned a grizzly bear costume once a week. This hands-on, albeit peculiar, experience provided him with an intimate understanding of bear psychology and behavior, laying a foundational knowledge that would prove invaluable in his later role.

Upon assuming the position of grizzly manager, Sarmento’s responsibilities expanded significantly. A considerable portion of his work involved extensive travel across vast distances to gently deter bears from venturing too close to agricultural lands. Bears, with their keen sense of smell, are naturally drawn to accessible food sources such as spilled or leaking grains. An unsecured silo, in particular, presented an irresistible buffet. Typically, Sarmento would arrive equipped with a shotgun loaded with cracker shells, a non-lethal deterrent designed to scare bears with a loud bang, and bear spray, a potent deterrent for close encounters. However, a harrowing incident, a near-fatal mauling, served as a stark wake-up call. This brush with extreme danger underscored the limitations of traditional methods and ignited a compelling need for a paradigm shift in his approach. "In that moment," Sarmento recounted, his voice tinged with the gravity of the memory, "I was like, I am gonna get myself killed." This realization became the catalyst for seeking more innovative and safer solutions.

The search for a more effective deterrent initially led Sarmento to explore the use of two Airedale dogs, a breed renowned for its ability to ward off bears on farms. However, these canine companions, while possessing some deterrent qualities, proved easily distracted and ultimately not the ideal solution for the specific challenges he faced. Simultaneously, the field of drone technology was steadily advancing, with these unmanned aerial vehicles (UAVs) beginning to be recognized as valuable tools for biologists across a spectrum of applications. These included tasks such as conducting aerial surveys for bird populations and meticulously mapping diverse habitats. The potential for drones to offer a new perspective and a safer method of observation and intervention became increasingly apparent.

It was in 2022 that Sarmento first deployed a drone in a real-world scenario, responding to a report of a grizzly mother and her two cubs raiding a silo just outside of town. The drone, equipped with advanced infrared sensors, proved instrumental in rapidly pinpointing the bears’ exact location. Furthermore, Sarmento utilized the drone’s auditory capabilities to gently encourage the bears to move away from the agricultural property. Researchers theorize that the distinctive whirring sound of the drone’s propellers might instinctively trigger a fear response in bears, mimicking the sound of an agitated swarm of bees. The success of this operation was palpable. "The whole thing was so clean and controlled," Sarmento stated, a sense of relief evident in his voice. "And I did it all from the safety of my truck." This experience validated the drone’s efficacy, demonstrating its ability to manage wildlife encounters from a secure distance, a significant improvement over previous methods.

The drone that Sarmento acquired for approximately $4,000 was a relatively straightforward model. It featured a thermal camera, invaluable for detecting animals in low-light conditions or obscured by foliage, and a battery life of about 30 minutes. Despite its modest specifications, this flying machine quickly demonstrated its remarkable potential. It allowed Sarmento to detect grizzlies in challenging and perilous terrain that would have previously necessitated a risky approach on foot. Areas such as dense undergrowth or remote river bottoms, often inaccessible or dangerous for human traversal, became readily observable and manageable with the drone’s aerial perspective. This technological leap significantly enhanced his ability to monitor bear activity and intervene before conflicts escalated.

Currently pursuing a PhD in wildlife ecology at the University of Montana, Sarmento’s vision extends far beyond his personal research. He is actively involved in designing a drone system that could be utilized by campus police to deter black bears from encroaching on school grounds. This initiative highlights the broader applicability of drone technology in urban and semi-urban wildlife management. Looking ahead, Sarmento envisions a future where artificial intelligence (AI) image recognition is seamlessly integrated into his wildlife management practices. Such integration could empower drones to autonomously identify bears and, crucially, to divert them away from high-traffic areas and populated zones, further minimizing the potential for dangerous encounters.

The ultimate goal of these evolving strategies, including the use of drones and advanced AI, is to prevent bears from developing behaviors that lead to conflict with humans. These conflicts often have dire consequences, typically ending tragically for the bear and sometimes proving fatal for people. The development of "out-of-the-box" technological solutions for wildlife management is still in its nascent stages, but the commitment to continuous exploration and innovation remains strong. "The out-of-the-box technology doesn’t exist yet," Sarmento affirmed, "but the hope is to keep exploring applications." He firmly believes that drones represent "the next frontier" in wildlife conservation and management, offering a safer, more effective, and ultimately more sustainable path towards harmonious coexistence between humans and the natural world. This forward-thinking approach, epitomized by the role of the wildlife first responder, promises to be crucial in navigating the increasingly complex challenges of wildlife management in the 21st century.
