4.01.02 - Growth models for tree and stand simulation
Unit 4.01.02 is principally concerned with the theoretical, mathematical, statistical and computational aspects of growth and yield model development, specification, calibration, verification, simulation, computerization and application. Model forms include those developed for tropical, temperate and boreal forest types and cover the entire range of stand structural complexity: individual-tree distance-dependent and distance-independent models, stand-level diameter distribution models and average stand-level models. Incorporating the impact of anthropogenic influences, such as thinning, forest fertilization, tree improvement and climatic change, on tree and stand growth through model refinement and adaptation is an evolving issue within this unit. Facilitating global interaction, dissemination and exchange of innovative modelling approaches through workshops, conferences, and publications, is one of the primary goals of this Unit.
