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.

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....
