Fig. 4. Wild boar reintroduction success in relation to habitat availability, i.e., number of habitat cells, and quality, i.e., breeding capacity of these cells, in a radial neighborhood of different scales. A and B represent population expansion or number of cells colonized in relation to habitat availability and quality, respectively; C and D represent extinction probability in relation to the same variables. Black squares: 50% forest coverage required; white squares: 10% forest coverage required. The number of habitat cells in a given subarea is related to the proportion of forest in a particular landscape, whereas breeding capacity is influenced by the composition of the forest.
