Abstract Der Beitrag stellt eine betriebswirtschaftliche Untersuchung zum Umbau von Fichtenreinbeständen in Laub- und Laubmischbestände vor. Untersuchungsgegenstand ist ein ca. 80 Jahre alter Fichtenreinbestand, der im Laufe der nächsten 40 Jahre zur Endnutzung ansteht und in einen Laub- bzw. Laubmischbestand umgebaut werden soll. Auf den Untersuchungsbestand werden unter Zuhilfenahme eines Wuchsmodells sechs verschiedene Waldbehandlungskonzepte angewandt, die sich hinsichtlich des Beginns des Waldumbaus, des Umbauzeitraumes sowie der Umbauintensität unterscheiden. Es wird jeweils eine Variante mit Umbau durch Voranbau und eine mit Waldumbau nach der Endnutzung berechnet. In die ökonomische Bewertung der Varianten gehen die erntekostenfreien Erlöse aus den Holznutzungen sowie die Kulturausgaben ein. Überlebenswahrscheinlichkeiten, die das unterschiedlich hohe Sturmschadenrisiko der verschiedenen Waldbehandlungskonzepte zum Ausdruck bringen, finden besondere Berücksichtigung in den Kalkulationen. Beurteilungskriterium der Varianten ist der Erwartungswert des Kapitalwertes, der für vier verschiedene Zinsforderungen, 0, 1, 1,5 und 2 % berechnet wird. Sensitivitätsuntersuchungen für veränderte Überlebenswahrscheinlichkeiten sowie Berechnungen zum Einfluß niedrigerer Kulturausgaben werden durchgeführt. Zuletzt werden die Auswirkungen sich verändernder Holzpreise und Erntekosten auf die Erwartungswerte der Kapitalwerte aufgezeigt. Es läßt sich zeigen, daß sich die Voranbauvarianten trotz der mit der Auflichtung verbundenen Zuwachsreduktion und der Erhöhung des Sturmschadenrisikos als in der Regel vorteilhafter erweisen. Dies begründer sich vor allem mit den niedrigeren Kulturausgaben für Voranbauten sowie damit, daß die ersten Einnahmen, die im Zuge der Auflichtung des Bestandes entstehen, wegen des kurzen Diskontierungszeitraumes in ihrer Höhe nur wenig gemindert in den Erwartungswert des Kapitalwertes eingehen. Deutlich niedrigere Kulturausgaben für alle betrachteten Konzepte können die Vorteilhaftigkeitsreihung zugunsten der Varianten ohne Auflichtung umdrehen.The paper presents an investigation on the restructuring of pure coniferous stands into broadleaved and mixed stands. The investigation is applied to an about 80 years old spruce stand to be harvested and restructured within the next 40 years. Six different forest management concepts are applied to the stand using a growth model. Each management concept aims to regenerate the spruce stand with broadleaved trees or with a mixture of broadleaved trees and conifers. The concepts differ as regards the time and way broadleaved trees are planted. Either broadleaved trees are planted advanced in the spruce stand of which the density index was reduced in order to let more sunlight reach the young plants. 15 or 30 years later the plantation will be a young copse and the stand will be harvested. Or broadleaved trees are planted on cleared area after harvesting the entire spruce stand. Proceeds and harvesting costs from simulation and planting costs enter the economic assessment. By reducing the density index of the old spruce stand the risk of storm-caused damage rises in comparison to the variants without advanced planting. The probabilities of survival that express the different risk of storm-caused damage due to different forest management measures are considered. The concepts are compared with their expected value of net present value. Four different interest rates are applied: 0, 1, 1.5 and 2 %. The impacts of the management concepts on stand development and the expected values of net present value are simulated by special models. Different planting costs are considered. Finally, the impacts of changing wood prices and harvesting costs on the expected values of net present value are investigated. It is shown that, in spite of increment reduction and rising storm damage risk due to reduced stand density, advanced planting concepts are more appropriate. This is due to the lower planting costs for advanced plantings and the fact, that first returns, as part of reducing stand density, are only slightly reduced when entering the expected value of net present value on account of the short discounting period. Distinctly lower planting costs for all concepts may offset the advantage of the concepts without stand density reduction.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
