Abstract:
An analysis of the climate parametrization scheme adopted by conventional forest gap models revealed that most models assume a constant climate and are difficult to calibrate consistently. Tree growth showed unrealistically sensitive threshold effects along ecological gradients of temperature and precipitation. A new parameterization was compared with its predecessors in terms of the model's capability to predict realistic study state species compositions at three test sites in the Alps. Applying the new model variant to some climate-change scenarios suggests that forest gap models are highly sensitive to climate parameterizations, regardless of the realism with which they simulate forests for the current climate.
