Waldschädling: Kahle Flächen als Chance sehen
WaldschädlingStudierende der Uni Freiburg untersuchen Schädlings-Management im Nationalpark Schwarzwald und stellen überraschende Ergebnisse zum Borkenkäfer vor.
Geschwächte Nadelbäume, vor allem Fichten, sind ideale Brutplätze für den Borkenkäfer. Der bohrt in die Rinde Gänge, wie sie auf dem Foto zu sehen sind. Die Weibchen legen ihre Eier ab. Der Baum wird dadurch massiv geschädigt. ⇥
