Scientific description of project area
The site contains the most important and wild sector of the outcrop of Messinian gypsum in Europe, an area of great geological and naturalistic interest. The layers of the so-called Gypsum Vein, inclined towards the plain, cause precipitous cliffs facing south (here one of the higher and wider) and with interesting Mediterranean character (Pistacia terebinthus, Rhamnus alaternus, Juniperus oxycedrus, Helianthemum appenninum, Fumana procumbens), contrasting with the more moderate slopes facing north, wooded, with fresh stations and rich in floristic elements typical of the high Apennines (Phyllitis scolopendrium, Galanthus nivalis, Tilia xvulgaris, Mercurialis annua, Corydalis cava, Laburnum anagyroides, Staphylea pinnata).
The whole area is characterized by widespread karst phenomena on the surface (blind valleys, sinkholes, ravines, erosive forms, plowed fields) and on the underground (sinkholes, resurgent, chasms and caves also of considerable development), which contribute to diversify peculiar morphologies, rich in contrasts and environments with high biodiversity. The site has a very diverse flora with Mediterranean and Central European elements, as well as an interesting aboveground and underground fauna. Woods and thickets mesophilic and xerophilous dominated by Quercus pubescens (91AA*), with slopes stations of Quercus ilex (9340), moist ravines with mesophilic flora, alternating with shrubs and grasslands, ex-cultivated land, scrubland and rocks colonized by ferns and therophytes, wide xeric meadows with orchids (6210*), in natural evolution to the Q. pubescens forests (91AA*). The caves have a well-preserved natural environment, with an abundance of ferns and specialized flora, colonies of bats and troglophile and troglobitic invertebrate fauna. Agricultural crops are relatively uncommon in the area, more common on the surrounding area. The area is inside the regional park Vena del Gesso Romagnola.

Importance of the project area for biodiversity and/or for the conservation of the species /habitat types targeted at regional, national and EU level
The biogeographic significance of the Monte Mauro is linked to its really high biodiversity, its Mediterranean flora, with many elements at the northern limit in the Apennines. Among these, the 91AA* Eastern white oak forests (92,63 ha) are here present as submediterranean forest formations with Quercus pubescens and Fraxinus ornus, Ostrya carpinifolia, Carpinus orientalis, Sorbus domestica, Spartium junceum, Scabiosa columbaria, Silene nutans, Coronilla emerus, Anthericum ramosum, Dictamnus albus, Geranium sanguineum, Epipactis helleborine, Rubia peregrina, Osyris alba, Dorychnium hirsutum, Peucedanum cervaria and stenomediterranean species such as Asparagus acutifolius, Rubia peregrina, Clematis flammula, Rosa sempervirens, Juniperus oxycedrus. The xeric meadows with Bromus erectus and many species of orchids (6210*) are covering 64,19 ha and are strictly linked to the habitat 91AA*. The structure of these forests is often modified and simplified by the widespread past coppice activity in private forests, now abandoned and also forbidden in the park, in which only the tall forest conversion is allowed; the privates are not interested in the conversion and the forests are abandoned or illegally coppiced, so it is very important to purchase these forests to manage the conversion and to stop illegal coppicing. Other serious threats are the fires and the uncontrolled cleaning of the forest, by cutting undergrowth and new plants; presence of invasive nonnative species Ailanthus altissima and Robinia pseudoacacia; wide presence of old re-forestation with non-native species Pinus nigra, Pinus sylvestris, Juglans nigra (all the wide forests areas includes in the project area and not classified as 91AA* could be this priority habitat if it wasn’t for the high presence of exotic pines); high agriculture pressure along the borders of forests.
