Ortho-Photo interpretation <strong>and</strong> mapping of the forest types<br />

The main forest formations were identified through the interpretation of digital orthophotos<br />

(1px / m resolution; max strain = 2m).It was possible to obtain a more precise classification of<br />

forest types in relation to the tone <strong>and</strong> texture of the pictures. The forest polygons were acquired<br />

directly from georeferenced digital orthophotos in a GIS environment (ArcView 3.2 ESRI inc.).<br />

Contextually, a geographic database for further processing was built. The polygon video scale<br />

capture was not less than 1:3,000 scale ratio.<br />

Field investigations<br />

In order to determine the main structural aspects of each forest type found on the digital<br />

orthophotos, a combined approach based on floro-vegetational, phyto-sanitary,<br />

phytosociological <strong>and</strong> physiognomical characteristics was carried out. Measurement on<br />

sampling areas, also documented by a detailed photographic survey, was performed by targeting<br />

plots, which allowed the compilation of field data sheets, useful for subsequent phases, <strong>and</strong> for<br />

outlining the current woodl<strong>and</strong> management .<br />

Field investigations regarded: 1) Biotic <strong>and</strong> abiotic environmental characteristics (st<strong>and</strong> site<br />

analysis); 2) Qualitative <strong>and</strong> quantitative features of the st<strong>and</strong>; 3) Productivity <strong>and</strong> nonproductivity<br />

functions of the woodl<strong>and</strong>s .<br />

L<strong>and</strong>scape changes through 40 years<br />

L<strong>and</strong> cover changes at regional scale can be summarized through a model based on three<br />

compartments (Figure 2):<br />
