Hunting and fishing harvest data collection: a horizon scanning exercise from the French context
Wildlife Biology, EarlyView.Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed
