About the Book

Die Forderungen zur Erhaltung der Waldhygiene und zur Steigerung des Wirtschafts- erfolges sind nicht immer vereinbar und stellen den Forstmann vor schwierige Aufgaben. Treten in einem Revier Massenvermehrungen von Schadlingen auf, so stellt sich die heikle Frage der chemischen Bekampfung, die in gewissen Fallen tiberhaupt die einzig gangbare Losung darstellt, urn den Bestand noch zu retten. Vor solchen Situationen stehen z.B. die verantwortlichen kanadischen Forststellen jedes Jahr, weil besonders der Schwammspinner Lymantria dis par in Bestanden Kahl- fraB und Vernichtung bringt, aber andererseits der Einsatz von Pestiziden mittels Flugzeugen die Entrtistung der Offentlichen Meinung auslOst. Obwohl Mischwalder gegentiber Schadlingsgradationen besser abgesichert erscheinen, konnen auch in diesen Kalamitaten ausbrechen, die rasche GegenmaBnahmen fordern. Solche Bekampfungsaktionen mtissen in bezug auf ihre Einwirkung auf die Biozonose sorgfaltig tiberprtift werden, da ein brutaler Eingriff aus verstandlichen Grtinden wegen seinen nachhaltigen Folgen schlimmer sein kann als das Ausbleiben jeglicher Behandlung. 1m vorliegenden Buch widmet Oberforstmeister Dr. Reisch in verdienstvoller Weise diesen schwierigen Vorgangen besondere Aufmerksamkeit. Seine rund zwanzigjahrige Erfahrung als Forstpathologe, wah rend welcher er zunachst als Pilot groBraumige Bekampfungsaktionen flog, urn alsdann eingehendst deren biozonotische Folgen zu untersuchen, und die sich darauf sttitzenden okologischen Studien, bilden daflir eine solide Grundlage. Die Bedeutung der Ntitzlinge und die Verfahren zu ihrer Erhaltung, Vermehrung und Schonung stehen im Vordergrund, wobei auch die Schattenseiten gewisser Pestizide objektiv dargelegt werden.
