National Park De Maasduinen, info from there website: To protect the heath against encroaching plants such as purple moor grass and blackberry bushes, it must be managed. This is achieved by grazing and by mechanical means. The grazing is done by sheep, goats and cattle. Most of these animals are in a fenced off part of the national park. There is also a fold near the Wellsche Hut forest in Well. From here the shepherdess and her flock set out to pasture particular parts of the moor. All animals, including those in the fenced areas, are monitored to ensure their wellbeing.
