The primeval flora has been transformed significantly as a result of deforestation and cultivation. The largest forest complexes are Bory Dolnośląskie (), Bory Stobrawskie in Stobrawa and Widawa areas, and smaller fragments of forests in Barycz and Oder River valleys. These forests are kind of multi-species deciduous forests, occurring in fertile grounds. The Oder River valley is reach in groups of mixed forests (beech, oak, hornbeam, sycamore maple, and pine). These forests, with protected status, are: Zwierzyniec, Kanigóra near Oława, Dublany, Kępa Opatowicka near Wrocław, Zabór near Przedmoście, and Lubiąż. The other forest areas are The Natural Park in Orsk, the areas of Jodłowice, Wzgórze Joanny near Milicz, and Gola near Twardogóra. Such types of forest like those which are the mainstay for wild game or nurseries, are inaccessible because of permanent fire hazard. Territories partly accessible (marked specially) are located in areas of Góra Śląska, Oborniki Śląskie, Wołowa, in the Oder River valley, and in Wzgórza Niemczańsko-Strzelińskie.
