Dieses Lehrbuch gibt einen Überblick über das komplexe, in zahlreiche Fachdisziplinen aufgesplitterte Gebiet der Ökologie. Im Fokus steht dabei die Ökologie der Baumarten und der Wälder in Mitteleuropa, einem vegetationsgeografisch eigenständigen Naturraum, der sich von der Ostsee bis zu den Südalpen und von Ostfrankreich bis nach Polen und in die Slowakei erstreckt. Die Ausführungen zu den Strukturen und Prozessen in den natürlichen Waldformationen werden ergänzt durch Forschungsergebnisse zu den ökologischen Auswirkungen der Forstwirtschaft. In eigenen Kapiteln werden auch die globalen Problemfelder Biodiversität, Klimawandel und Waldschäden behandelt.
Biologie, Geografie, Landschaftsplanung, Landschaftsökologie, Agrar- und Forstwissenschaften sind Studiengänge, in denen ökologische Themen seit jeher einen wichtigen Teil der Lehrinhalte einnehmen. Hinzu kamen neue Studiengänge für Ressourcenmanagement, Ökosystemmanagement, Natur- und Umweltwissenschaften. Diesen Fachrichtungen bietet das Lehrbuch eine Einführung in die ökologischen Zusammenhänge. Hierbei folgt es einem hierarchischen Aufbau von den Bäumen über die Baumpopulation und das Waldökosystem bis zur Landschaft. Die umfassende Berücksichtigung aktueller und spezieller Literatur macht das Lehrbuch auch zu einem Handbuch und Nachschlagewerk für Masterstudenten, Doktoranden und Dozenten.
