NOMINATION OF THE DOLOMITES FOR INSCRIPTION ON THE WORLD NATURAL HERITAGE LIST UNESCO 94 sion of the clasts, the abundance or shortage of nutrients, and geographic location. All these colonies fall under the single class of Thlaspietea rotundifolii, named after the guide species, Thlaspi rotundifolium. At the higher elevations, in realms that are snow covered for most of the year, the best known and most visible bloom is probably that of the Alpine poppy (part of the Papaveretum rhaetici), often accompanied by Saxifraga sedoides and Achillea oxyloba, as well as Linaria alpina and other species indifferent to substrate. At very high elevations, on the terrigenous substrates that cause events of solifluxion, the dominant species is Leontodon montanus. On fine detritus, in the sub- Alpine belt, Athamanta cretensis and Trisetum argenteum have formed an association (which replaces, in the greater part of the Dolomites, T. distichophyllum, found abundantly in the central chains and in the internal and continental Dolomite region). On soil that is coarser (gravel and pebbles) but damp, and therefore more vulnerable to events of summer aridity, the spring flowering Alpine Butterbur (Petasites paradoxus) flourishes as does the Adenostyles glabra, whose blooms emerge in the summer. Limited to some external areas but of important bio-geographical interest are the Brassicaceae colonies (guide species Alyssum ovirense, present on the Vette di Feltre, on Monte Serva, and M. Pramaggiore), the primroses (Cortusa matthioli: Alpi Feltrine, Tesino and lower Agordino area) and colonies of fescues, such as Festuca nitida (Dolomiti Bellunesi and Friulane). Somewhat more widespread are blue fescue (Festuca pulchella). At lower elevations, the quarries are colonized by succulent plants of the Sedum genus, Moehringio- Gymnocarpietum robertiani, by colonies of Achnatherum calamagrostis and Epilobium dodonaei. Not lacking are spectacular examples, albeit localized of coarse stone screes undergoing consolidation by the work of the hearty and showy clumps of Festuca spectabilis. In the Prealpi Carniche we can also find Festuca laxa. On silica-rich detritus at higher elevations, dominant species include Oxyria digyna, Geum reptans, Poa laxa, and Ranunculus glacialis. In grassier areas which are subject to lengthy snow coverage, a prevalent species is the Luzula alpino-pilosa. Somewhat less common, on the coarse silica stone screes, is the association of Cryptogramma crispa (parts of the Lagorai). Also interesting are the communities that colonize the flood areas and pebbly river banks. As regards species thriving in lime-rich soil, we also remember the aspects of Leontodon berinii and Chondrilla chondrilloides or Calamagrostis pseudophragmites while on silica, we only name the extreme eastern penetrations of Epilobium fleischeri. Less widespread with respect to the Central and Western Alps, but no less important in terms of quality, is the typical plant life of the snowy valleys. Guide species include the dwarf willows: Salix herbacea (it prefers silica), Salix retusa (indifferent) and Salix reticulata (it prefers lime). The areas localized near the snowfields are characterized by meagre but rather specialized plant life and often have interesting detritus contributions. Soldanella pusilla, Veronica alpina, Potentilla brauneana, Sibbaldia procumbens, Arabis caerulea, Gnaphalium supinum, and Gnaphalium hoppeanum are a small number of vascular plants that, in the more extreme habitats, leave space to cryptograms when the snow cover begins to exceed 9-10 months per year.
NOMINATION OF THE DOLOMITES FOR INSCRIPTION ON THE WORLD NATURAL HERITAGE LIST UNESCO 95 Rocky walls and detritus strata on the Tofane (Dolomiti d’Ampezzo – Belluno). other realms This perfunctory and unavoidably superficial panorama on the various aspects of the Dolomite landscape should not omit at least one reference to other areas that play host to unusual plant colonies. – Shelters under rock formations, with nitrophilous flora, nourished by the evacuations of wild hoofed animals that pause there. The guide species are Cynoglossum officinale, Hymenolobus pauciflorus, Lappula deflexa. – Nitrophilous habitats near the grazing lands and rest areas in areas of accumulation. Rumex alpinus, Chenopodium bonus-henricus, Urtica dioica, Stellaria nemorum. – Colonies of nitrophilous high grass in the wooded clearings or among the shrubs. Adenostyles alliariae, Cicerbita alpina, Aconitum vulparia, Peucedanum ostruthium. Only in the Dolomiti Pesarine (Dolomitis Pesarinis and Dolomiti di Sapade) do we observe the very rare and flamboyant Eryngium alpinum. – Dry areas along walls: Sedum in several species, Saxifraga tridactylites, Scleranthus. – Open clearings in the woods with decomposing organic substances. Epilobium angustifolium, Rubus idaeus, Atropa belladonna (beech woods). – Peripheral areas of woods: thermophils with Geranium sanguineum, Aster amellus, Origanum vulgare. Several mesophils with Trifolium medium, Vicia sylvatica. – Ploughed or heavily developed areas. There are various ruderal or segetal associations, related to crop planting or other areas subject to clearing, located on roadsides or in uncultivated areas. Interesting, here and there, are several relicts, now in the process of disappearance.
