Abstract
FORSS E.; MALTAMO M. SARAMAKI J. 1998. Static stand and tree characteristics models for Acacia mangium plantations. A method and models to calculate stand characteristics for example in forest inventory applications are presented for plantations of Acacia mangium. The method consists of four parts: equations for estimating the parameters of the diameter distribution function (Weibull) and individual tree height total tree volume and utilisable stem volume. The parameters of the diameter distribution function and of the general tree height model are derived from stand variables which are quick to assess in a forest inventory. Total volume estimation is based on tree diameter and height utilisable volume estimation is based on tree diameter and a variable top diameter limit for pulpwood. The diameter distribution and height models are based on mainly remeasured data on 62 semi permanent and permanent plots (1.0 to 7.4 y of age) in South Kalimantan Indonesia. The accuracy of the model chain is tested using the bias and root mean square error of the predicted stand volume as criteria.
