The flora of the calcareous mountains near Feltre (Belluno) is composed by about 1,600 species of vascular plants, some of them endemic or very rare and in this sense may be regarded as particularly rich. New records for the regional flora and some critical species are discussed.

This study deals with the floristic composition of the grasslands in the Vette di Feltre (SW-Dolomites, Prov. Belluno, Italy) and with the potential of this territory for grazing. The vegetation types of economic interest above timberline are: Seslerio-Caricetum sempervirentis, Nardetum and Rumicetum alpini. These have heen mapped and the area covered by each association has been calculated. The yearly phytomass production was estimated with field measurements. On the basis of the floristic composition it is possible to calculate the fodder production in the area and consequently the optimal grazing pressure. Intensive grazing in the last centuries produced huge changes in the vegetation of the area.

Synecological studies of the vegetation have been carried out in the glacial circus Busa delle Vette at about 2,000m (Vette di Feltre, Prov. Belluno. Italy), on limestone. The microclimate of the grasslands association (Seslerio-Caricetum semperuirentis and Nardetum) is mesic, whereas the pioneer Adenostyli-Heracleetum, colonizing the scree slopes, has warmer and drier conditions. On the contrary the Adenostyles glabra-association and the Rumicetum alpini are confined to more humid sites. The pedological study confirms such relations. The earliest stage of the pedogenetical evolution with (A)-C profile of the Adenostyli-Heracleetum develops a soil characterized by the presence of a mollic epipedon under the Seslerio-Caricetum sempervirentis. Intensification of the pedogenetic processes leads to the formation of an illuvial horizon in the Nardetum-soils. Further developmental stages with peculiar features, can be identified in the Rumex alpinus- and Adenostyles glabra - associations.

;Pignatti, ErikaPignatti, SandroTHE VEGETATION ABOVE TIMBERLINE IN THE VETTE DI FELTRE MOUNTAINS. These mountains (at the southern margin of the Dolomites) were not covered by ice during the cold phases of Pleistocene, and therefore their flora is particularily rich in relict or endemie elements. The phytosociological investigation shows that the vegetation is well diversified: 15 associations belonging to at least 4 classes are described in the alpine and subalpine belts ofthis territory. Most of the associations bave been already described from other parts of the Dolomites, but in this territory most of them present particular floristic and sociological features. Three associations are new: Alyssetum ovirensis, Adenostyli-Heracleetum polliniani and Cortusetum matthiolii. The phytogeographical, phytosociological and ecological problems of this vegetation are discussed.391 957 - PublicationLa vegetazione di Erera-Brendol-Campotorondo(EUT Edizioni Università di Trieste, 1983)Lasen, CesareTHE VEGETATION OF THE ERERA-BRENDOL-CAMPOTORONDO ALPS NEAR FELTRE. The mountain group Erera-Brendol-Campotorondo is one ofthe most interesting landscapes of the Dolomites near Belluno. The vegetation consists of about 20 types which are described in their floristical composition and ecological problems. The timberline lies in about 1600m and may be regarded as particularly low for the Southern Alps. The karstic plateau is covered by a monotonous formation of Pinus mugo, Rhododendron and other prostrate shrubs. Cattle- and sheep-grazing has played the most important role in the past and secondary grasslands are widespread. Rocks, gravels, and snow beds, although relatively limited, show a rich endemic flora and quite rare vegetation types.
