Geology

The Streckelsberg was formed during the last ice age as a push moraine

 (Oberförster) Schrödter afforested the Streckelsberg in 1818 and 1819 in its present form with beech trees in order to better protect the hill and the village of Koserow behind it from the harsh sea winds and from drifting sand. Schrödter was born in 1753 in Klein Behnitz (in the March of Brandenburg). After several years of training he became a royal court and district hunter (Hofjäger and Revierjäger). From 1810 he was the district forester in Zinnowitz. After the afforestation of the Streckelsberg, he became the senior forester in the Neupudagla Forest District in 1819. He died in 1828.

The Wolgast Gazette (Wolgaster Anzeiger), No. 61 of 21 May 1900, reported that: "Schrödter rendered great service in the spheres of forestry and sand dunes. He knew, in a masterly way how to anchor and cultivate the bare, infertile sands on the beach at Koserow, with which the wind played games. In particular, he did a great job of afforesting the Streckelsberg at the seaside resort of Koserow, which is now protected by the woods against the harsh sea winds and unwelcome sand drifts.
