Washington County's tunnel has helped several species cross under Highway 4 safely. From top left clockwise: painted turtle, snapping turtle, mink, ducks. “Last August, our first snapping turtle come through,” county park manager Peter Mott says. “This June, a lot more came through. So yes, turtles are using the turtle tunnel.”
Comfortable migration Prefabricated openings in the solid top of the Climate tunnel are different to drainage gratings and maintain stable air-pressure conditions within the tunnel. The climate openings also ensure that the temperature and relative humidity in the tunnel match ambient external conditions, and slow down the movement of air in the tunnel. Foxes, hedgehogs, mice and other small animals also feel comfortable using the tunnel.
These beautiful bridges are just for animals
Chinese Wildlife Corridor -- "Sustainable Design takes into account the human interaction with other species. It fosters healthy cohabitation, which does not contaminate the natural world, and it creates corridors by which animals can still follow their natural migration patterns, despite urban proliferation." - Jo Anna Nedergaard

New research from Virginia: "The subject animal detection system... detects the crossing of large and medium-sized animals and provides data on their location along the length of the [300-m-long buried] cable. The system... generates an invisible electromagnetic detection field around buried cables. When the detection field is perturbed, an alarm is declared and the location of the intrusion is determined....

[VIDEO] A Wild Way to Move: "As you travel through Banff National Park animals are travelling too -- over your roof and under your wheels. Wildlife crossing structures and highway fencing in Banff National Park have reduced large animal deaths by more than 80%. So which animals adopted crossing structures first? Who prefers overpasses versus underpasses?
