  1. Install culverts or tunnels as road crossings

    A small, replicated study in 1987 of two tunnels with barrier fencing in Henley-on-Thames, England, UK (Langton 1989) found that approximately 2,750 common toads Bufo bufo used the tunnels during 18 migration nights. In the first two nights, only about 10% of 2,200 toads recorded behind the fence were estimated to have used the tunnels. This increased to a maximum of 43% of toads recorded in one night. Fencing was installed between the two tunnels creating a W-shaped catchment of 600 m. A trip counter was set 0.2 m into the entrance of the tunnels.
