Some notes about landscape evolution in the Trieste Karst. Reading of the topographic maps time series (map 1:25000 "Poggioreale del Carso", foglio 40a iiso)
Benedetta Castiglioni - (27/1,1998)
Three editions (1915, 1926, 1962) of the same topographic map - 1:25,000 scale - were analysed in order to obtain some information about karst landscape evolution during the present century. Both natural and human landscape were observed, expecially landforms, vegetation and soil use. The analysis gives prominence in particular to progressive forest growing. Two main difficulties were met in this analysis. First, the scale 1:25,000 is not very suitable for looking at the extremely fragmented karst plateau landscape. Second, the comparison between the three maps is not always possible because they are drafted with different mapping techniques.
