Toad tunnel in Germany. Amphibian and reptile tunnels, also known as herp tunnels, are a type of wildlife crossing that is positioned beneath a roadway. The tunnels allow amphibians and reptiles to cross roads without the risk of being crushed by a vehicle. They have been used by toads, frogs and salamanders.
Wildlife crossing is the umbrella term encompassing underpasses, overpasses, ecoducts, green bridges, amphibian/small mammal tunnels, and wildlife viaducts (Bank et al. 2002). All of these structures are designed to provide semi-natural corridors above and below roads so that animals can safely cross without endangering themselves and motorists ...
The bridge is meant to allow animals to circulate through and thrive in habitats that are fragmented by human development. [1] The crossing is particularly critical for the mountain lions of the Santa Monica Mountains, which have declined and become genetically isolated [2] because the Ventura Freeway prevents them from moving between the mountains and the Simi Hills to the north.
With 8-foot (2.4 m) tall, noise damping corten steel walls on both sides, the bridge is designed to appear to crossers as a small hill. [6] [7] The bridge has a 250,000-US-gallon (950,000 L) underground cistern to keep the bridge's plants irrigated via rainwater. [8]
The bridge is covered with native vegetation, including trees and shrubs, which is intended to replicate a native forest ecosystem enticing to the animals. [2] There is a fence on the bridge to prevent certain large animals such as sambar deer and wild boar from crossing into Bukit Timah, which is too small and fragile to sustain them. [ 2 ]
