The "Romeinenweerd" is a fairly small part in the floodplains of the "Maas" river. The area consists of a forested wetland/swamp with three small waterbodies and surrounding meadows, adjacent to the "Maas" river. The ponds are always interesting for waterfowl, like Common Pochard, Common Teal, Northern Shoveler, Gadwall and Tufted Duck. In spring, sometimes Garganey can be present. Little Grebe is often seen on the eastern en western pond. The eastern and middle pond both contain a small island where geese breed during breeding season, like Greylag Goose and Canada Goose. The western pond is mostly surrounded by reedbeds and are always worth a check for certain reedbirds, like Reed Warbler, Water Rail and Reed Bunting. If you're lucky, a Bearded Tit shows up or even a Great Bittern can be seen foraging on the edge of the reedbeds. Especially in the middle pond, Common Kingfisher can often be seen and heard.
The forested areas are home to a variety of common songbirds, like Common Chiffchaff, Willow Warbler and Greater Whitethroat. You're allowed to get "off road" and walk through the area. Sometimes you'll scare a present Woodcock or even a Great Bittern. The main attraction, though, are the small flocks of European Serin, being present in the bushes. They can often be heard and seen from the start of the track near the parking lot. Although many years ago, flocks of 20-30 individuals could be present. Nowadays, numbers vary between 1-4 individuals, but sometimes more. In winter, the forested area is a good place to find flocks of Lesser Redpoll and Siskin feeding in the trees.
The meadows on the northeastern side of the area are good for species like European Stonechat and Marsh Warbler. Sometimes Whinchat can be present. The scattered bushes are always worth a check for Red-backed Shrike. In winter, these meadows are often used by Great Egret. On the southwestern side of the area, an agriculatural field is present on which Grey Partridge and Common Pheasant can be present.
The river itself can be a good spot for Goosander, besides common species like Great Crested Grebe and Eurasian Coot. Large numbers of gull, mainly Black-headed Gull, fly in southern direction, following the river, towards their sleeping grounds near the city of Roermond.
The area is easy accessable on foot, although there're no paved roads present. Most tracks are covered with grass but the area can get very swampy after much rainfall. You're not bound to stay on the tracks and you're allowed to walk around freely, but watch out for the swamps, because you can get very wet and dirty.
