Abstract

This research deals with the geomorphological characteristics of the Salse di Nirano area located at the margin of Modena Apennine, and with the changes in the landscape induced by the istituzione of a Natural Reserve in this area.Le salse (mud volcanoes) di Nirano, essendo il fenomeno pseudo-vulcanico meglio sviluppato of Italy, sono state descritte in numerosissimi lavori e nel 1982 sono diventate a Natural Reserve. The aims of this study were to get an in-depth knowledge of the geomorphological characteristics of the Reserve and to carry out a qualitative assessment of the geomorphological sensitivity of the area related to the institution of the park.The study was conducted according to the following investigation phases: (i) bibliographic research; (ii) morphological analysis through the interpretation of aerial photographs taken in various periods; (iii) field survey; (iv) Elaboration of a Digital Terrain Model; (v) Elaboration of geomorphological maps referring to the features in 2002 and in 1973; (vi) Assessment of the geomorphological sensitivity. The DTM and the geomorphological maps have been elaborated by means of ArcView GIS. In this area, where silt-clay soil types (Plio-Pleistocene age) crop out, landforms and deposits resulting from the “endogenetic” activity of the mud volcanoes, due to running water, due to gravity, due to anthropogenetic activities and poligenetic landforms. Landforms and deposits have been distinti in active and dormant/inactive. In the geomorphological maps also the hydrography has been indicated.A qualitative assessment of the geomorphological sensitivity induced by the istituzione of a Natural Reserve in the Salse di Nirano area has been carried out by the comparison of the features represented in the geomorphological maps of 2002 and of 1973. The comparison ha evidenziato that the environmental protection of the area ha comportato, in conseguenza della riduzione dell'attività silvo-pastorale, una crescita della vegetazione arbustiva che ha, in gran parte, stabilizzato landforms and deposits due to running waters and due to gravity. L'abbandono degli specchi d'acqua artificiali ha portato alla creazione di piccole paludi e al colmamento di laghetti. Concerning the anthropogenetic landforms, si è riscontrata una riduzione of the areas affected by creep due to grazing, l'abbandono of a quarrying area and of an impianto industriale e la realizzazione di un parking per i visitatori. From literature, si puo' affermare that che considerable reduction of anthropogenetic disturbances has allowed the increase of the apparati of the mud-volcanoes which can now develope with no constrains.
