3PG - PLM_12

"3PG is an acronym for Physiological Principles Predicting Growth. It is a generalized forest carbon allocation model, published by Landsberg and Waring (1997), that works with any forest biome and can be run as an Excel spreadsheet by practicing foresters given a few days of training. The model uses relatively simple and readily available inputs such as species growth tables, latitude, aspect, weather records, edaphic variables, stand age, and stand density to derive monthly estimates of gross primary productivity, carbon allocation, and stand growth. The model has the capacity for specifying thinning regimes, although the function needs further refinement. In recent iterations, the 3PG model has been linked to satellite imagery of canopy photosynthetic capacity to model forest growth across landscapes (Coops et al. 1998). Intended as a practical management tool, the model is under constant revision to incorporate new research data, simplify application, and broaden its usefulness. Belowground processes and allocation are one of the least developed aspects of this model and we hope to contribute to the model's development with our envisioned research and application." http://www.fsl.orst.edu/mycology/ss/3PG.htm
