German to English Other Zoology bark beetles

Study on the connection at the landscape level between habitat factors and the spread of the bark beetle (Ips typographus L) in a forest. Infrared aerial photographic surveys were carried out of the forest to determine the extent of infestation. “Mithilfe jährlicher durchgeführter Color-Infrarot-Luftbildbefliegungen wurden die Totholzflächen aufgenommen und digital vektoriell erfasst.”
