摘要: The ENETWILD consortium updated in August 2019 suitability maps of wild boar occurrence and relative abundance based on hunting statistics, providing predictions at 10x10 km. External validation of this relative abundance model and a new downscaling on a 2x2 km grid was addressed in the ENETWILD report in January 2020. In this report, we update and incorporate additional data to provide new maps of wild boar suitability with a resolution of 2x2 km, obtained from a presence‐only algorithm, and a new model based on hunting yield data for MS and neighbouring countries. Hunting yield‐based modelling provides further novelties in two ways: new predictor variables and new (two) modelling approaches, i.e. smooth bioregion modelling and two‐step independent bioregion modelling). Internal validations and comparisons among previous and new suitability and hunting yield models were also addressed …
