Description: Existing models present some shortcomings in predicting forest growth and carbon dynamics, especially for forests with high structural complexity. Many natural or semi-natural forests are composed of several tree species in various storeys with different height classes and cohorts (age classes). Thus, the natural forest mosaic is characterized with extensive interactions of multiple tree species, forest growth, and light conditions, which in turn cause vertical and horizontal differentiation in the natural forest mosaic. The architecture of trees in particular and a forest in general is the outcome of diverse ecological and physiological. Furthermore the spatial distribution of trees influences habitat heterogeneity and affects regeneration patterns, tree growth, mortality rate, and resource-use in the forest floor. The key drivers shaping the forest structure are triggered by the competition for resources (light, nutrients, and water), forest management, and human and natural disturbances (e.g. fire). It is therefore clear that many processes are linked by forest structure and these are deeply influenced by it. The aim of this task group is to study and evaluate eco-physiological processes that are involved and their responses to forest structural complexity.
