Thermal drones save hundreds of fawns in Bavaria as mowing season begins
Germany: A Bavarian wildlife rescue group is turning to thermal imaging drones to find and save fawns hidden in tall meadow grass before farmers begin annual mowing, a shift that has increased rescues more than twentyfold.
Every spring, thousands of fawns across Germany are killed by mowing machinery. Baby deer instinctively freeze when threatened — a defense that hides them from predators but makes them invisible to farm equipment operators.
Founded in 2020, volunteer group Rehkitz-Rettung Mangfalltal once searched meadows on foot, with volunteers walking fields in lines. The work was slow and labor-intensive, yielding just 10-15 rescued fawns each season.
Now, using DJI thermal drones, the team can scan fields faster and more reliably. AI features on the drones help pilots distinguish fawns, baby hares, and ground-nesting birds from other heat sources in dense vegetation.
Since adopting the technology, the group’s annual rescue count has jumped from 10-15 to between 300 and 350 fawns.
Operators fly the Matrice 4 Series at 80–100 meters, using precision positioning controls to spot heat signatures, verify them visually, and pin locations with centimeter-level GPS accuracy. Coordinates are shared instantly with ground teams who retrieve the animals before mowing starts.
The German case study includes a step-by-step video guide covering drone operations and safe handling of fawns once found.
The effort joins a growing list of “drones for good” cases, from locating landmines in Ukraine to delivering life rings to drowning swimmers and clearing trash from Everest slopes.
