The marshy meadows retained the tracts of alder forests and riparian alder forests; the forest of highest value is located west of the village of Bobowiska. It boasts many rare plant species. Beneath the tree stand of black alder, you can find the undergrowth of blackcurrants and redcurrants, and the multi-varietal ground cover featuring the Marsh Ferns, Water Parsnips, Milk Parsleys, Lesser Pond Sedges and Elongated Sedges, Yellow Irises, Bittersweet Nightshades and Marsh Marigolds, less often – Marsh Callas and Water Violets. In fact, the entire area surrounding Bobowiska and Wólka Kątna boasts natural unpolluted forests, access to pure water, and excellent sites for mushroom pickers, anglers, hunters, bicycle ride lovers and enthusiasts of hiking amidst silence and tranquillity.
