Brzeszcze lies along regional roads nr. 933 and nr. 949, and its name comes from the brzost (Ulmus glabra) trees, which once were abundant in the Sola river valley.
Rare tree species occurring include the large-leaved lime (Tilia platyphyllos) and varieties of whitebeam, as well as pedunculate oak (Quercus robur) and wych elm (Ulmus glabra).
Nowadays both hills are mostly covered by broadleaf forests (with Acer platanoides, Fraxinus excelsior, Tilia cordata, Ulmus glabra, Quercus robur, Corylus avellana), very uncommon for the region situated in the taiga belt, and have a peculiar fauna and flora.
The main tree species found on the site include ash (Fraxinus excelsior), common beech (Fagus sylvatica), small-leaved lime (Tilia cordata) and wych elm (Ulmus glabra), as well as English oak (Quercus robur) and sessile oak (Quercus petraea).
The Wych Elm Ulmus glabra cultivar 'Dovaei' was raised by the Andre Leroy nursery at Angers, France, as Ulmus dovaei before 1868.
The Wych Elm Ulmus glabra cultivar 'Fastigiata Variegata' was listed in the Baudriller (Angers, France) nursery catalogue in 1880.
The Wych Elm Ulmus glabra cultivar 'Tiliaefolia' was first mentioned by Host in Fl. Austr. 1: 329.
