Presentation of the 30 variables selected from farmers and 10 variables selected from hunters on which principal component analysis and multiple component analysis was performed.
| Farmer characteristics | Pasture management | Reproduction management | Hunter characteristics and management | Carcass management | Interactions between wild suidae (IDWS) |
|---|---|---|---|---|---|
| Farming is the main activity (Y/N) | Maximum surface of the outdoor area (<50/>50 ha) | Births during all the year (Y/N) | Number of pig farms in the neighborhood (quantitative)a | Carcasses left outdoor (Y/N) | WB in proximity (seen in the farm/estate) (Y/N) |
| Pork produced as controlled designation of origin (Y/N) | Pastures are totally fenced (Y/N) | Mating in non-fenced areas (Y/N) | Practice of beat hunts (Y/N)a | Offal left outdoor (Y/N) | WB/pig interaction (Y/N) |
| Size (<100/>100 ha) | Share of pastures with other pig farmers (Y/N)a | Sterilization of sows (Y/N) | Number of hunting days/week (quantitative)a | Home slaughtering (Y/N) | IDWS frequency (seen more than 4 times a year) (Y/N)a |
| Breed “Nustrale” (Y/N) | Use of summer pastures (Y/N)a | Reproductive stock sold (Y/N) | Shooting feral pigs (Y/N)a | Sexual interactions (Y/N) | |
| Cross bred with Corsican breeds (Y/N) | Additional food supply all year (condensed) (Y/N) | Fattening offspring sold (Y/N) | Ratio hunted hybrids/total hunted pigsa | Agonistic interaction (Y/N) | |
