Diversity of Segetal Flora in Salix viminalis L. Crops Established on Former Arable and Fallow Lands in Central Poland

The flora of willow (Salix viminalis L.) plantations consists various plant groups, including plants related to arable land, called segetal plants. Knowledge this is important for maintaining biodiversity in agroecosystems. aim the study was assess central Poland, depending on land use before establishment (arable or fallow) and age plantations. Moreover, also check presence invasive, medicinal, poisonous melliferous species. vegetation accompanying identified based an analysis 60 phytosociological relevés performed using Braun-Blanquet method. For each species, following parameters were determined: class; family; geographical historical group; apophyte origin; biological stability; life-form; status as medicinal (herbs), results statistically processed. Segetal species accounted 38% willow. former richer than those fallow. Mostly, short-lived native dominated. In line with plantations, number decreased. share apophytes increased, anthropophytes Furthermore, many valuable found among
