Abstract The paper presents some aspects concerning the technical solutions identified for the ecological restoration of some wetlands from the Lower Prut floodplain, located both on Romanian and Moldavian sides, recently implemented within some international environmental projects. There are the confluence area between Elan and Prut Rivers in Romania, respectively the —Lower Prut“ Scientific Reserve, in . Both locations have a significant importance either in terms of biodiversity conservation, flood control, or alluvia and nitrates mitigation. The ecological restoration solutions for the Lower Elan/Prut River have in view the improvement of hydrological conditions in the confluence area as well as soil erosion control in the watershed, by land-use restructuring and afforestation of arable and pastures lands that are severe degradated by water erosion and/or by a high salt content. As regard to the —Lower Prut“ Scientific Reserve, in Moldova, due to the major threats on it, such as: natural resources overexploitation - reed, wood, fish, eutrophication, oil pollution etc., all of these often correlated with a totally inappropriate management of the Reserve, the project intended, as a first phase, the elaboration of a —Management and Ecological Rehabilitation Plan of the Reserve œ Implementing and Monitoring“, as well as, later on, the analyzing of possibilities for extension to the North of the Scientific Reserve and setting-up of —Trilateral Biosphere Reserve“ between Romania, Moldova and Ukraine. Keywords: ecological restoration, wetlands, biodiversity reconstruction, soil erosion, pollution
