The city park "Steinse Groen" is a fairly new park on the eastern side of Gouda. The park mainly consists of high bushes and forested areas with small marshlands, ponds and ditches. In spring, the area is home to a variety of common songbirds, like Common Chiffchaff, Blackcap and Greater Whitethroat, but also breeding birds like Lesser Whitethroat and Icterine Warbler are present. The small ponds and ditches are used by common species of waterfowl, like Gadwall, Tufted Duck and Eurasian Coot, but species like Common Kingfisher, Common Pochard and Common Teal are also present. In summer, Common Tern forages above these ditches and sometimes small groups of Black Tern fly overhead. Small reedbeds are present in the northwestern en southeastern part of the park. Here, small numbers of Sedge Warbler and Reed Warbler breed, but also Cetti's Warbler can be found. The shallow parts of the area are home to grass snake and some parts also contain orchids. In winter, the area is mainly used by flocks of Siskin and Chaffinch.
Large extensive pastures are located on the northern side of the park. In summer, small numbers of Black-tailed Godwit and Eurasian Skylark breed here. In winter, large flocks of Greater White-fronted Goose, Barnacle Goose and Mute Swan forage on these pastures. The ditches between these pastures are used by large numbers of Eurasian Wigeon and many other species of waterfowl. Also, large groups of Great Egret can be found here.
The area is easy accessable on foot and by bike. You can park the car at several places near the park (see P on the map). Just follow the paved roads into the park and you can make a circular walk of about 2.5 km. There is a small "trekpontje" located in the northern part of the area, which means a small DIY ferry to cross a ditch. There's also an information sign in the eastern part of the park, explaining the nature on the extensive pastures to the east.
