Nature

The Scandinavian glacier was a mighty sculptor of the landscape. Over millennia it created landforms according to the laws of physics and chemistry and with the mysterious dependence of the kinetics of the solar system, a part of the  universe. When it was retreating, its melted waters continued to shape the surface of the Earth. They carved wide river valleys (e.g. the Vistula and the Drwęca valleys) and deep lake basins. They deposited colourful rocks and debris transported from the north highland areas to create moraine hills, winding eskers, distinctive streamlined hills known as drumlins, and sandy outwash plains. Places where the glacier stopped advancing feature relatively high hills (100-150m above sea level). Stretching between the hills, the Dobrzyń Plateau is bounded by the valleys of the Vistula, Drwęca and Skrwa rivers. Post-glacial landscape with a multitude of lakes was called the Dobrzyń Lakeland. Its southern part, occupied by the Dobrzyń Land, is distinguished by long, finger-shaped, deep ribbon lakes with high banks, and kettles – small, shallow, oval lakes in hollows formed  when blocks of glacier ice melted out. The largest lakes on the Dobrzyń Lakeland, i.e. Lake Urszulewskie (250 ha), Lake Żalskie (Wielgie – 160 ha), and Lake Wielkie (133 ha).make a perfect haunt for anglers who rarely miss the opportunity to catch a pike, zander, perch, tench, eel, carp, bream, roach or whitefish here. In the north-east the Dobrzyń Land is surrounded by the Drwęca, a unique ichthyological reserve. The meandering Skrwa river, for a thousand years a natural border between the Dobrzyń Land and Płock Mazovia, offers canoeists perfect views of its wooded banks.

The steep banks of the Vistula on 'Dobrzyń riverside', definitely more attractive than the flat 'Kuyavian riverside', make a perfect viewpoint  for watching regatta on Lake Włocławskie. The Rypienica and the Ruziec rivers, lefttributaries of the Drwęca, are also interesting water trails.For the next two thousand years after the glacier retreated, the landforms it created were further transformed by rains, winds and droughts. As a result, barren moraines and outwash plains were covered with soil. Winds and floods carried seed of trees and other plants from different directions. 

 

 

All nature, living and non-living things, united to shape the landscape. Nature adapted to the unstable weather with changing temperatures, producing a vast range of colours. The man started cultivating a variety of plants thus adding his own combination of  colours including green, yellow, brown, and black hues.After ages of merciless exploitation of nature, the man turned to establishing nature reserves, national parks and landscape protection areas. There are several nature reserves in the Dobrzyń Land: Szumny Zdrój, Tomkowo, Okalewo, Zielona Kępa, Bobrowisko (Beaver Lodges), Torfowisko Mieleńskie (Lake Mielne Peatbog), Góra Modrzewiowa (Larch Mountain), and Kulin. Located on the steep banks of the Vistula, Kulin provides home for the white dittany, a rare perennial plant which may have been the biblical burning bush of Moses. The name is derived from its strange property of releasing oils which can ignite spontaneously during the blooming season in dry and hot air.The entire Drwęca (the length of 219.3km) is a unique ichthyological  reserve and  an important habitat for 37 species of fish found in lowland and mountain rivers, e.g. the  trout, the sea trout, the vimba bream or the salmon. The communities of reptiles, amphibians and mammals are thriving in the surrounding area, where big elks and deers, roe deers, wild boars, martens, weasels, badgers, otters,  and beavers are regular inhabitants. The water shrew is an interesting semi-aquatic mammal, whose saliva contains venom paralysing its prey. 140 bird species live in the Dobrzyń Lakeland permanently and 49 fly to spend winter here. Most of them are protected, especially the black stork, the lesser spotted eagle, the Eurasian hobby, the kestrel, and the white-tailed eagle. The north-eastern area of the Dobrzyń Land was designated as the Górzno-Lidzbark Landscape Park comprising the nature reserve Szumny Zdrój. In the south-east the Brudzeń Landscape Park includes the confluence of the Skrwa and Vistula rivers.
