Results
The probability of current pine presence responded positively with
temperature (β=0.046, p=0.005, Table 1) and negatively with
precipitation (β=-0.051, p<0.001) when employing the dataset
belonging to the PLOT network. The probability of current pine presence
responded negatively to temperature (β=-0.007, p<0.001) and
precipitation (β=-0.020, p=0.009) when employing the NFI data. Finally,
the probability of current pine presence responded positively to
temperature (β=0.199, p<0.001) and negatively to precipitation
(β=-0.192, p<0.001). See Table 1 for AUC and
R2 values and Appendix 1, Fig. S1.2 for ROC curves.
When spatially forecasting with the PLOT and ART datasets, the pine
distribution will likely expand in range to higher elevations and remain
the same in lowland Fennoscandia (Fig. 1).
