Plantations of energy plants are the alternative form of post-agricultural and degraded land management. Particularly, small-area plantations of the tree species, including the willow Salix sp., raise local natural values of degraded habitats and are a dwelling place for numerous entomofauna, birds and mammals. Herbaceous vegetation accompanying short-rotation coppice (SRC) constitutes at the beginning a competition for energy species plantings and therefore is subject to chemical and mechanical control. In successive years, it may increase local biodiversity at the level of plant species and associations, both in ruderal habitats and extensively used agricultural lands. In the presented paper, results of the study referring to evaluation of the floristic and phytosociological diversity of herbaceous vegetation accompanying selected 4–5-year-old willow short-rotation coppices (SRC) situated on lands adjacent to the Odra River estuary (Western Pomerania) in different soil-habitat conditions are showed. Investigations were carried out in willow SRCs located on degraded sandy silts and sewage sludge-fertilised silts, fallow post-farmland and degraded grassland. The largest number of species onfirmed by the highest Shannon-Wiener’s diversity index (H) and species evenness index (J) was characteristic of SRCs set on sandy silt fertilised with sewage sludge, wet grassland and fallow post-farmland when compared to those on sandy silt and over-dried grassland. The analysis of vegetation showed a strong predominance of anthropogenic associations (synanthropic and seminatural) over autogenic (natural) ones.
