The paper presents the river valley physiography and the selected hydraulic, physics and chemical parameters of the upper section of small lowland river – Pichna Szadkowicka (the Warta river catchment, Central Poland). The strong relationship between the river and river valley habitat’s characteristics and the plant species and vegetation diversity was noted. Around one hundred (93) of vascular plant species was noted in total, including Listera ovata (strictly protected) and partially protected: Hedera helix, Viburnum opulus, Frangula alnus and Hepatica nobilis. The high natural (botanical) and landscape values of the researched section of the Pichna Szadkowicka river with adjacent parts of Wojsławice forest complex justify additionally their protection in the network of forests reference plots and of the High Conservation Value Forests (HCFV).

The old forest complex of Rzepiszew (76.81 ha of land) is located in the east part of Szadek commune. It is surrounded by arable fields and meadows. At present it is a timber forest, but forest management is based on ecological rules. 260 Vascular plant species forming 55 families have been found in this area during field research which was carried out in years 2006-2010. The identified species represent different types of growth (= life forms in Raunkiaer's terminology) Hemicryp- tophytes have been found to dominate. The flora contains plants from various ecological groups classed according to light conditions, moisture of soil, soil acidity and soil trophy. Most of them are stenotopic plants - they have a limited (narrow) ecological amplitude. The true forest species are the most valuable components of flora. Seven among them are protected by law.
