Abstract

This publication is intended as a series of articles under a common title, presenting study results on segetal vegetation in the area of the Konin Brown Coal Basin and its broadly understood peripheries. This area of 820 km² is located in the central part of Konin Province and takes up to 1/6 of its acreage. The results were based on 592 phytosociological releves made with the use of Braun-Blanquet method. The study presents 28 phytocoena (15 associations, 8 communities of importance similar to an association, 5 communities of an “incomplete” nature), 4 of which are syntaxa rarely cited in reference to our country. Part I of the analysis will present a profile of the area of studies, with particular attention given to a specific character of the region's agriculture. Moreover, it will introduce the material and methods of research, as well as a systematic overview of singled out communities. In subsequent parts segetal communities will be discussed.
