UWSP Graduate researcher takes conservation to new heights with drone technology

Amanda Griswold, a graduate student in the College of Natural Resources at the University of Wisconsin-Stevens Point, is using drones equipped with thermal cameras to transform how biologists monitor waterfowl populations and protect critical habitats.
 
Griswold’s research, guided by her adviser, Assistant Professor Ben Sedinger, explores how uncrewed aerial systems can improve waterfowl conservation efforts. Sedinger, the Kennedy-Grohne Chair in Waterfowl and Wetlands Conservation, provided mentorship throughout the project, which was supported by a Wisconsin Department of Natural Resources grant. Additional funding included a scholarship from the Wisconsin Waterfowl Hunters Expo and Wisconsin Wildlife Federation, as well as the David R. Luukkonen Waterfowl and Wetland Graduate Student Fellowship awarded by Ducks Unlimited.
 
For decades, waterfowl surveys relied on aerial flights in small planes and ground-based observations. These traditional methods have limitations, particularly in detecting every bird in each area. But Griswold’s study, conducted over two years, shows that drones are changing the game.
 
Griswold and her team used drones to survey a variety of wetland habitats. The drones, equipped with thermal imaging technology, effectively detected birds in areas where traditional surveys often struggled. By flying at heights that minimized disturbance, the drones ensured the birds’ natural behaviors remained unaffected throughout the surveys.
 
“Our findings show that drones are a reliable and efficient tool for monitoring breeding waterfowl populations,” Griswold said. “They improve detection rates while reducing the need for time-intensive ground surveys.”
 
This research directly benefits conservation by providing data on waterfowl populations and habitat use, allowing conservationists to better prioritize restoration and management efforts. By identifying areas with high breeding activity or critical habitats for broods, resources can be allocated more effectively to ensure the survival of these species. Additionally, the reduced labor and cost associated with drone surveys make conducting more frequent or widespread assessments possible, giving managers the tools they need to respond to emerging challenges, such as habitat degradation or climate change impacts, in real-time.
 
Sedinger highlighted the project’s collaborative approach and its potential impact.
 
“This research combines advanced technology with ecological expertise to address real-world conservation challenges,” he said. “Drones give us the ability to observe waterfowl in ways we couldn’t before, allowing for more precise conservation strategies. It’s an exciting step forward for waterfowl and wetland conservation.”
 
As wildlife populations face threats from habitat loss and climate change, conservationists are turning to tools that guide restoration efforts with precision. Thanks to Griswold’s innovative work, Sedinger’s mentorship and support from state agencies, Wisconsin’s wetlands offer a hopeful outlook for waterfowl populations and their habitats.
