Model outputs for update of occurrence and hunting yield-based data models for wild boar at European scale: new approach to handle the bioregion effect, May 2020 update

These maps are models obtained in intermediate phases of the ENETWILD project based on available information. There are frequent updates in order to improve the results.

Objectives:

- Incorporate additional data to provide new maps of wild boar suitability with a resolution of 2x2 km >>> file 3_June_2020_suitability_2x2.tif
- New model based on hunting yield with different approaches to handle the biorregion effect >>> files 1_June_2020_HY_nut01_10x10_twostep.tif  &  2_June_2020_HY_nut01_10x10_pca.tif

Model settings and predictors:    
- Hunting yield modeling including biorregion effect as bioclimatic PCA scores
- Hunting yield addressing biorregion effect in a two-step procedure with independent parametrization for each bioregion

Conclusions guiding future methodological steps:
- For wild boar suitability maps at 2x2 km, additional data on survey effort is critical in the southern bioregion
- Hunting yield model predictions at 10x10 km grids overestimated the hunting bag numbers obtained from the external datasets
- HY model with independent parametrization for each bioregion performed better that previous and new strategies
