Wildlife crossing
Wild creatures risk their lives every time they need to traverse the thousands of highways humans have constructed through wildlife habitat and, sadly, millions of animals are killed on roads each year. Thankfully, many countries now construct wildlife crossings – also called green bridges, ecoducts, natuurbrug (like this one in Wierden in the Netherlands) and écoponts (in France). These can be overpasses or underpasses, and they are an expensive venture.
Are they worth it? Well, officials in Banff National Park in Alberta, Canada, would say categorically yes. Over the span of 20 years they built 44 bridges and underpasses so wildlife could cross the Trans-Canada Highway which divides the park. During this time traffic accidents involving wildlife dropped by 80 percent.
France built the first wildlife crossing in 1960 and the private highway company AFRR continues to construct safe passageways there, but the Netherland leads the initiative, with an impressive 600-plus crossings, and counting. In fact, the Dutch have the world's longest animal crossing too – the Natuurbrug Zanderij Crailoo is an overpass that’s almost a kilometre long. Now our wildlife friends can cross the road anytime, safely.
