Rapid changes are expected in the mountain forest and the forest-alpine transition zone due to global warming. Since steep temperature-productivity gradients characterize these marginal areas, two fundamental effects are expected: (1) an expansion of the forest by colonization of non-forested areas and migration of the alpine tree line; (2) increased growth of existing trees which will have a significant impact on carbon sequestration and future carbon pools.

Prediction of diameter distribution with MSN and SUR
This study used a non-parametric most similar neighbour (MSN) approach and a parametric seemingly unrelated regression (SUR) approach to model and to predict diameter distributions in conifer forests. Continue reading
