"De Regulieren" is a semi open to open landscape, consisting of pastures, small forests and damp meadows. The central part of the area consists of open pastures with cattle. The surroundig fences are often used by Meadow Pipit and European Stonechat. In spring, when the vegetation of the pastures is still low, some areas contain damp meadows, which are used by mainly waders and ducks. Little Ringed Plover, Ruff and Black-tailed Godwit can often be found on these parts. Pairs of Common Teal can also be found in the small ditches between these pastures. If you're lucky, you can hear Common Quail from within these pastures. Sometimes large herds of roe deer can be present. In the surrounding forests, species like Willow Warbler and Garden Warbler breed and in the higher bushes species like Lesser Whitethroat and Greater Whitethroat can be found. Also, Common Cuckoo and Golden Oriole breed in small numbers in the area. The area contains small patches of reedbeds, which are used by Reed Warbler.
Many birds of prey make use of the area as hunting and breeding habitat. Many Common Buzzard and Eurasian Kestrel can be found in the central part of the area. Eurasian Hobby hunts on dragonflies above the wet pastures and, if you're lucky, you'll encounter a European Honey-buzzard. Also, European Marsh Harrier uses the area to hunt for prey.
In winter, the central part of the area is low in numbers of birds. Sometimes, large flocks of Fieldfare and Redwing can be found here. The forests are used by mixed flocks of tits and finches. Small numbers of Goldcrest can also be found within these flocks. The surrounding pastures of the area are often used by large groups of Great Egret.
There are two parkingspots (see P on the map) to access the area in which you'll be able to make a circular walk of about 4 km. Almost all of the trails are unpaved roads and on most of them you'll just walk on grass. After a rainy period, these roads can be very wet and dirty. There are several vantage points around to take a look over the central part of the area.
