Research on protective belt and forest vegetation, significant to the scenery of the rivers Neris, Vilnia and Dūkšta, was carried out in 2001–2004. An evaluation of the ecoaesthetical quality of 25 sceneries of the rivers Neris, Dūkšta and Vilnia led to the determination that most (52 %) of the sceneries were picturesque. The species composition and aesthetical features of protective belt and forest vegetation were also evaluated. The ecoaesthetical quality of protective belt and forest vegetation and sceneries decreased when an abundance of alien plant species were present.
