Groningen is the least fragmented city in the Netherlands. Green corridors make for a well-veined green city. As a new link in this network, ecoduct (wildlife crossing) Meedenpad connects two green areas on both sides of the Oostelijke Ringweg. The Meedenpad is an ideal access road to cross this ring road. There are few buildings, it lies in the lee of the residential area and there are virtually no barriers to reaching the path. The first urban wildlife crossing of the Netherlands consists of a 4-metre wide bicycle and pedestrian path separated from a 3.5-metre wide fauna passage by a hedge of apple roses. To provide shelter for mammals such as hedgehogs, deer, hares and foxes, a substrate for planting and stumps were placed in this part of the crossing. An interactive panel and a webcam provide information about the animals that use the wildlife crossing.








3.1 Hedgehog house

wt_deluxe_hedgehog_house_wag_jpg_20940_0Special hedgehog houses can be bought for hibernating. This is not necessary: if there are quiet nooks in the garden, with some branches and leaves, it will make its own nest. So don’t tidy up too much. A hedgehog is a master at getting rid of slugs and snails, for that reason slug pellets should obviously not be used in the garden. Because a hedgehog’s territory is larger than a single garden, it is important that they can get in and out. Especially fences form an obstacle. Leave a space of about 10 centimetres under the fence, so hedgehogs and other small mammals can crawl through.

Haagse Bos, an inner-city park of 100 hectares with country houses and monumental ponds, was once part of a vast area of woodland. Urban development and busy roads now surround the woods, limiting the ecological connection with the adjacent areas. For small mammals such as the red squirrel and pine marten, the area is too small to keep populations healthy in the long term. To prevent inbreeding a larger gene pool is needed and thus a larger habitat. To this end, a fauna passage was constructed over the motorway between Haagse Bos and the estates Clingendael and Oosterbeek. Squirrels and pine martens use treetops to get from one place to the next, so they would not readily crawl through a tunnel under the road. The bridge consists of triangular steel girders supported by striking steel columns on both sides of the road. Wires were strung from the surrounding trees to the bridge for the animals to make the crossing. This gives the crossing a total length of 55 metres. A simple rope bridge was not possible because of the size of the road and the safety rules for traffic and animals. Camera observations showed that the bridge is regularly used, according to natural migration peaks of the squirrel, in spring and autumn.
