Balmer See

The northwestern tongue of land, Cosim, together with the two small islets of Böhmke and Werder are designated as a nature reserve and bird sanctuary.

At that time it belonged, together with five other parished on Usedom (Ückeritz, Mellenthin, Loddin, Suckow and Krienke), to the estate of the bishops of Cammin.

In a deed dated 15 March 1270 they exchanged these parishes, at the request of Duke Barnim I of Pomerania-Stettin, for Damerow in East Pomerania (near Naugard), that had belonged to the Premonstratensian abbey of Grobe near Usedom.

Around 1980 the numbers of black-headed gulls got out of hand: there were 14,000 of them, their droppings encouraged the rampant growth of stinging nettles and rarer, more sensitive species of bird had no chance.

In winter white-tailed eagles may also be seen, west of the nature reserve footpath to the old manor house of Dewichow (small holiday village) and the transition to the lake of Krienker See.
