Fig. 4. Transition matrices between 1774–1975 and 1975–2000 performed on all the land-cover types for the San Petrone massif. Totals are given for each year and each type as % of the landscape surface. Bold numbers indicate the maximum relationship between the two maps. Vertical and underlined values correspond to the sum of transition rates within the delimited transition submatrix between the different generic land-cover types.
