Install culverts or tunnels as road crossings Amphibian Conservation

A replicated study in 2011–2012 of 26 wildlife tunnels with guide walls at three wetland sites on the Great Hungarian Plain, Hungary (Faggyas & Puky 2012) found that amphibians used the tunnels in large numbers in the first year. Between 120 and 1,800 amphibians were caught at the end of each tunnel over two weeks. European fire-bellied toads Bombina bombina and the targeted spadefoot toad Pelobates fuscus were recorded in highest numbers. The Danube crested newt Triturus dobrogicus, a priority conservation species, also used the tunnels. At one site, ten times more amphibians passed through two new climate tunnels than an existing adjacent concrete culvert. A total of 26 polymer concrete ACO Wildlife Pro climate tunnels, guide walls (300–600 m/tunnel) and stop channels (under side roads that bisected guide walls) were constructed under three roads in autumn 2011. Amphibians were monitored using nine pitfall traps/road in April 2012.
