New Study Shows Promise in Using Drones to Prevent Wolf Predation on Livestock – Implications for California

A groundbreaking study published in Global Ecology and Conservation this month demonstrates that drones could be an effective non-lethal tool for preventing wolf predation on livestock. The 2022 study, conducted in Southwest Oregon through a partnership between the U.S. Fish and Wildlife Service, Oregon Department of Fish and Wildlife, and USDA APHIS Wildlife Services, focused on wolves with histories of livestock conflicts, including those with direct connections to California’s wolf population.

The research centered on three wolf groups: the Rogue Pack, which has contributed at least five wolves to California’s population through dispersal; the Gearhart Mountain Pack, established by a male wolf (LAS13M) from California’s Lassen Pack; and OR-103, a wolf that had moved between Oregon and California before being poached in Oregon in 2022.

The results were striking: prior to drone deployment, researchers documented 11 confirmed wolf predations on livestock within just 20 days (0.55 predations per night). After implementing drone surveillance and hazing, only two predations were recorded over 85 days (0.024 predations per night) – a 96% reduction in predation rates.

The drones, equipped with thermal imaging cameras and speakers, allowed operators to monitor cattle and detect wolf presence at night. When wolves were spotted, operators could use the drone’s speaker system to vocally haze the wolves away from livestock. In one documented case, this intervention successfully stopped an active attack on a steer, which survived with only minor injuries.

Notably, since the study’s completion, there have been no confirmed wolf predations on livestock from either the Gearhart Mountain Pack or the Rogue Pack in Southwest Oregon.

The study’s success raises important questions about its potential application in Siskiyou County, where wolf populations continue to expand and conflicts with livestock are an ongoing concern. With Siskiyous diverse landscape and growing wolf population, this technology could offer a new tool for wildlife managers and ranchers, particularly in areas where lethal control is not an option.

Further research is needed to understand long-term effectiveness, including how wolves might habituate to drone presence, and how the technology performs in different terrain types common to California’s wolf country. The study authors are currently expanding their research to evaluate these factors and develop more comprehensive guidelines for drone use in wolf-livestock conflict prevention.

What are your thoughts on implementing this technology in California’s wolf management strategy?
