Figure 4.

Continuous predictions of the timing of occurrence of fruiting bodies of the winter chanterelle (Craterellus tubaeformis) in Denmark from 2017 to 2021. Predictions are shown for models trained with observation data corrected for temporal and spatial bias, for models using AgERA5 weather data and Global Forecast System data. Values of point biserial correlation coefficient (r) are provided, measuring the association between predicted values and the dates of actual observations. All values are statistically significant (α = .001).
