Recurring to other sources of information analysis, with a particular reference to National
statistics and forest studies about Italian southern regions (D’Autilia et al. 1967; Merendi 1954;
Quattrocchi 1950; IFN 1985) an alternative scenario can be delineated, in which the extensions
have not decreased (Table 3), but, on the contrary, they show a slow and constant increase as
Figure 3 shows.

4. Discussion
Figure 3.Forest expansion trend in Sardinia during the twentieth century.
If these interpretation analysis is correct, forests in Sardinia remained constant or increased
along twentieth century, because of the main law on Forests (Law 3267, 1923) that imposed an
accurate direct management of forests. According to what is reported in Beccu, 2000, Sardinia,
before 1877 (when a permissive law on woods-cut was delivered) had more than 4,000 km 2 of
woodland that actually seem to be fully restored.
