Synthesis: Growth Models for Tropical Forests: A Synthesis of Models and Methods

Tree bark as a non-timber forest product: The effect of bark collection on population structure and dynamics of Garcinia lucida Vesque

“…In addition, a matrix model is only as good as the information on which it is based and no model can be expected to fully describe the expected behaviour of the system (Anderson, 1998). The strengths and weaknesses of matrix models have been repeatedly stressed (Hartshorn, 1975;Sarukhan, 1978;Anderson, 1998;van Groenendael et al, 1988;Caswell, 1989;Vanclay, 1995;Zuidema, 2000). According to Boot and Gullison (1995), matrix models still appear to be useful for modelling the effects of some nontimber forest products (NTFP) harvest, particularly those that do not change the disturbance regime of the forest.…”

Individual-tree diameter growth and mortality models for bottomland mixed-species hardwood stands in the lower Mississippi alluvial valley

“…Mixed-species forests with a high diversity of tree species exhibit a huge range of life forms and stem sizes. In these forests, age is irrelevant as a modeling variable (Vanclay, 1995), and the DBH (diameter at breast height) distributions of species (species group, or stand) may be not unimodal, and thus may not be described by standard distribution functions. Therefore, some modeling approaches used successfully for mono-specific stands have limited utility in multispecific and heterogeneous forests (mixed forests).…”

Economics of Oil Production from Pongamia (Millettia pinnata) for Biofuel in Australia

“…In the absence of empirical evidence on growth and yield of Pongamia, a biomass production model was developed from the well-established principles of growth modelling for trees [40,49,50]. The biomass growth model of a representative tree within a commercial plantation setting was calibrated with the assistance of subject matter experts as described in the acknowledgments.…”

“…The recurrent synthesis and degradation, inherent to growth of long-lived plants, can be expressed as a function of weight and growth that, over time, result in a sigmoidal pattern with inflection points in the growth curve. The slope and the asymptote in the growth pattern are strongly influenced by site conditions [39,40,49,50,53].…”
