Everstenmoor, Protected wetland area in Oldenburg, Germany.

Everstenmoor is a 117.5-hectare nature reserve southwest of Oldenburg, bordering the Ammerland district and lying north of the Küstenkanal. It protects a largely uncultivated remnant of the former Wildenlohmoor, with hand-cut peat pits now filling with water, rosemary heather, and birch-pine bog woodland. Drier eastern parts were converted to grassland.

The reserve received protection status in 1990 and was expanded in 2018 to better align with European nature conservation guidelines. This growth reflected changing views on how much land should be safeguarded for natural habitats.

Farmers cut peat by hand here for fuel until around 1960, when the practice stopped and the land was left to grow over. The old hand-cut pits, now filling with water and plants, still mark the surface. Since then, moorland has been grazed by Heidschnucken sheep and birch saplings are cleared to keep the open heath.

You can reach the reserve through marked trails starting from Kavallerieweg and Sandfurter Weg. The Freesenweg path offers an organized route for walking through the landscape without getting lost.

The reserve shelters the Kreuzotter, Germany's only venomous viper, alongside the grass snake and the moor frog. Since about 1960, when peat digging stopped, grazing Heidschnucken sheep have been brought in to keep birch scrub off the heath.
