The vegetation cover of the Głuszec stream valley was investigated. The article presents a list of 294 recorded species of vascular plants from 65 families and, also, 47 plant associations from nine classes, from three dynamic vegetation circles: Carici elongatae-Alnetum, Fraxino-Alnetum and Querco- -Ulmetum minoris. Six types of vegetation complexes were documented. Their phytocoenotic structure was shown in a table containing 􀍻􀎂 relevés made in sigmassociations. The preliminary results of research on the dynamics of Dactylorhiza incarnata population, occurring in one of meadow complexes, were presented. The Głuszec stream valley was recognised as the region of exceptional natural plant cover within the city of Poznań and proposed to be incorporated into the green network of the Poznań Agglomeration. The valley was also included in the agri-environmental program. An active protection of grassland ecosystems is achieved by adhering to the requirements of this program and additional recommendations of an expert botanist.
