It is thus important to know whether common and unprotected native species are reliable indicators for protected and rare species. The aims of this paper were to: (a) analyse the distribution of rarity and commonness of species, by using different criteria and (b) test if groups of species with different conservation value (aliens, unprotected natives and protected natives) differ in terms of their rarity distribution, using the data collected in 604 plots sampled within 21 protected areas of the central Italy. Three different criteria were used to classify species as rare or common. Pearson correlation, least-squares regressions and Chi-square test were used to compare the species richness patterns or rare and common species as well as protected, unprotected native, and alien species. The number of species classified as common and rare widely differ according to the adopted criterion. The number of common and rare species were statistically correlated at both the plot and protected area scales, even if at the plot scale the predictive capacity was rather low. Protected species were significantly rarer than expected, while unprotected species were significantly more common than expected; alien species confirmed to be particularly rare in our study area, with some major alien species being totally absent in the recorded flora. The richness patterns of common and rare species defined according to different criteria have been found to be correlated one to the other, and both are well related to the richness of protected and alien species at both the plot and PA scales. Protected species were better related to common species, while alien species were better related to rare species. Despite rare species were numerically more than common species, and the richness pattern of total species was better predicted by common species than rare species. Common species confirmed to be good indicators of species richness patterns and also of protected species.

The two species were found in a recently described Betula pendula stand, located in the Belagaio forest, Colline Metallifere, southern Tuscany. Fifty-two bryological taxa (19 liverworts and 33 mosses) were recorded in this area. The forest of Belagaio is the southernmost site known for Sphagnum subnitens and Sphagnum subsecundum in Tuscany. Plagiomnium ellipticum is another new species for Tuscany.
