Is It More Visible from Above? Comparison of the Effectiveness of Methods for Locating the Bobak Marmot Marmota bobak (Rodentia, Sciuridae) Burrows in Ukraine
Burrow systems detection is a reliable method for counting Bobak marmots. We compared the effectiveness and labour costs of three methods of burrow detection: ground survey, unmanned aerial vehicle survey and satellite survey. The research was conducted in 2021 (Kyiv region). Ground surveys mapped 4...
