The reserve includes various tree species, including willows, oaks, poplars, and beeches. Moldova’s largest and oldest stand of old-growth oak trees can be found in the reserve; the oldest tree is recorded to be more than 450 years old. It is also home to many birds, most notably herons, which nest in the trees near the river. The herons are so abundant that the local people call the area the “land of the herons”. Many animals can also be found in the reservation, including a small herd of bison, brought to the reserve after an agreement with the Polish government. Another interesting attraction within the reserve is a landscape of hills and knolls called the “one hundred hill”; to this day how they were formed remains a mystery.
