He was the surface of 335 ha and a partial reserve status. The reason for establishment of the reserve was to protect the northernmost extreme of the natural, insular position of fir (Abies alba), who found here excellent conditions for development and the extremely favorable microclimate for themselves.

Jata

The forest cover of Lukow county is uneven. The biggest forest complexes occur at the west border of the unit. Besides some smaller or bigger wooded grounds are scattered all of the county area. The most interesting objects of that type include the forest complex called Kryńszczak with natural reserves Jata and Topór established in 1933 and reinstated in 1952. The reserves protect habitats of the fir tree at the north-east border of its occurrence. Local topographic features and the situation of that reserve at the water divide between the Krzna and Kostrzynia river basins results in a diversification of global and habitat conditions

We owe the most complete monograph ob fossilised fauna occurring in the Jurassic drift in Jata reserve to professor Makowski. Thanks to professor Makowski’s research name Łuków is known to geologist all over the world. The numerous specimens of fauna preserved in Jurassic drifts in Łuków include: ammonites, belemnites, shellfish and snails. They have been very well preserved and therefore is a precious material; for scientific research on animal forms of distant (165 million years ago) geological ages.
