Regeneration is a key element in the life cycle of forests, and long-term responses such as species composition and basal area simulated by forest growth models are sensitive to regeneration. However, these sensitivities are not yet well characterised (e.g. which systems are recruitment limited?). Further, with less intensive management practices becoming more abundant, and changing climatic conditions, regeneration processes need more attention when striving for robust models of forest dynamics.
The aim of this TG therefore is:
(1) review existing approaches for handling natural regeneration in models of forest growth and long-term forest dynamics
(2) perform a systematic evaluation of the sensitivity of different models to different, empirically-based formulations of tree regeneration as embedded in different models of forest growth available within the PROFOUND consortium
(3) make recommendations as to the way forward with modeling of tree regeneration and how to best incorporate improved regeneration submodels in forest growth models.
