Species Favourability Shift in Europe due to Climate Change: A Case Study for Fagus sylvatica L. and Picea abies (L.) Karst. Based on an Ensemble of Climate Models

Figure 3

Comparison of the climate index growing degree days (°C) at the inventory plots. The ensemble of climate data is shown for the period 1971–2000. Growing degree days are calculated depending on the length of the vegetation period defined as a period above 5°C. Base line of the temperature sum is 5°C (input data for modeling the distribution of Picea abies).
