The first interventions aimed at limiting the risk of desertification has been an opportunity for more related approaches to the ecology and the circular economy. In particular, the techniques have been applied with innovative variations to fit the best in the ecological context. The choice of native species is fundamental: they recolonized the area decreasing the risk of the prevalent invasive species. The terracing has recovered the considerable volumes of cyclopean stones. The positioning of the biomat in jute, has blocked volumes of biomass from pruning in order to enhance, for the soils, the organic content. In addition, coupled with the bio-rollers with vine shoots, it has evolved the traditional technique of pre-seeded fascine. The hydroseeding operations have added seeds of the local germplasm, while those of hydromulching have reused posidonia stabilized on site Multidisciplinary monitoring (botanical, ecological, erosive, pedological, already started during construction) and maintenance have been ongoing for over 3 years. All the interventions have been perfectly successful: the area now has a very high plant cover and better floristic quality and the ecosystem approach opens up new scenarios (technosoils, mulch from posidonia, bio-rollers, etc.) of research and with possible interactions for the marble, vine and bathing industries. Abstract The realization (2014) of the "First interventions aimed at limiting the risk of desertification in the suburban Portella del Cerriolo Park" (Custonaci, TP) has been an opportunity for more related approaches to the ecology of the site and of the circular economy. In particular, the techniques (Dry Sowing of Seed & infructescences, Hydroseeding, Hydromulching, Slope Fascine & Biorollers, Branch Layering of Gullies, Planting, Slope Protection Biomat & Organic Pillows, Vegetasted stone walls and Cyclophoidal walls) have been applied with innovative variations and in order to fit the best in the ecological context. The choice of native species, identified thanks to an accurate floristic study, is of fundamental importance; they recolonized the area, decreasing the risk of the first prevalent invasive species. The terracing has recovered the considerable volumes of stone, even cyclopean, deriving from the overlying quarries. The positioning of the biomat in jute, has blocked volumes of biomass 2 from pruning in order to enhance, for the soils, the organic content. In addition, coupled with the bio-rollers with vine shoots, it has evolved the traditional technique of pre-seeded fascine. The hydroseeding operations have added seeds and flowers from the collection of the local germplasm, while those of hydromulching have reused posidonia stabilized on site for at least 14 months with low salt content. To the posidonia residues have been added pruning lawns from the maintenance of urban green and citrus. Multidisciplinary monitoring (botanical, ecological, erosive, pedological, already started during construction) and maintenance have been ongoing for over 3 years. All the interventions have been perfectly successful: the area now has a very high plant cover and better floristic quality and the ecosystem approach opens up new scenarios (technosoils, mulch from posidonia, bio-rollers, etc.) of research and with possible interactions for the marble, vine and bathing industries.
