Fig. 6. Classification of potential reintroduction areas in Denmark attending to the most restrictive habitat scenario for boar reintroduction success, i.e., high forest requirement, and the most pessimistic risk scenario, i.e., boars also expand and contact farms thorough areas with low forest cover. Area type: (A) high population expansion, high risk relative to the expansion; (B) high expansion, proportional risk; (C) low expansion, high relative risk; and (D) low expansion, proportional to low relative risk. Area: (1) North Sealand, (2) South Sealand, (3) Fynn Island, (4) Silkeborg Forest, (5) Djursland Peninsula, (6) Rold Forest, and (7) Thy.
