Abstract
ABSTRACT Growth modelling is an essential pre-requisite for evaluating the consequences of a particular management action on the future development of a forest ecosystem. Such growth models are not yet available for many indigenous tree species in India. Dalbergia sissoo is an important timber species found in India and growth models are required for its effective management in the region. This paper presents equations for estimating the potential stand density limiting tree survival and for modelling the mean stand density in pure even-aged stands of Dalbergia sissoo. Two different models were investigated for estimating mortality in stem numbers in the stands. This paper also compares seven different stand level models for projecting basal area development. The models tested belong to the path invariant algebraic difference form of a non-linear growth function. They can be used to predict future basal area as a function of stand variables like dominant height and stem number per hectare, and are crucial for evaluating different silvicultural treatment options. The performance of the models was evaluated using different statistical criteria. The model proposed by Pienaar and Shiver performed best and hence this model is recommended for use in projecting basal area development in Dalbergia sissoo stands in the study area.
