Do excavations risk to remove the exotic vegetable species indiscriminately uprooting also the native vegetation?
Exclusively removing single plants, from the beginning of the aerial part till the end of the radical system, requires unrealistic capacities. The excavation is justified by the fact that the fragment stay, also of moderate dimensions, in a wetland zone during advanced silting, would retrigger the invasive process and would not allow to reach the objective of rejuvenation of the wetland zones and diffusion of swampy habitats of community importance. Furthermore the project expects the “elimination of the dense formation of exotic (amorfeti)” and not the removal of single Amorpha specimen, for whose ecology and distribution in the area it is, in fact, impossible to remove every single plant but it is necessary to remove the whole formation of “amorfeto” which may also have specimens of other kinds inside it, such as Phragmites australis, whose conservation is not jeopardised by this intervention. Their vegetable associations typical of wetland zones inside the area have been kept almost
