Photography: Wildlife Crossings

Wildlife crossings are structures that allow animals to cross human-made barriers safely. They may include: underpass tunnels, viaducts, and overpasses (mainly for large or herd-type animals), fish ladders and green roofs (for butterflies and birds). Wildlife crossings are a practice in habitat conservation, allowing connections or re-connections between habitats, combating habitat fragmentation. They also assist in avoiding collisions between vehicles and animals, which in addition to killing or injuring wildlife may cause injury to humans and property damage.

  6. I like the grass-roofed buildings. On Vancouver Island, there is a building with goats grazing on the roof.

  9. Amazing. I agree, the fish ladder is cool, never heard of those before.
    Though sometimes I wonder how the animals know there’s a wildlife crossing 2 miles to the south? And how do the crabs recognise this is a bridge?

    • I think the animals during their migration follow certain routes. And as you can see in the picture above, they’ve fenced the side of the road with a low sheet of plastic which keeps the crabs off the roads and directs them through the crossing. In any case the aim is to reduce the road toll of animals.

  13. Some of those are beautiful – I never knew they built animal crossings that are so big. The fish ladder – particularly cool.

  14. These are super-useful and look quite good in their environments too!
