Frog Fencing

Frogs depend on water for breeding, with females laying eggs in pools or ponds. Some species stay close to water throughout their lives, while terrestrial frogs live mostly in forests or grasslands but still return to water to breed. These terrestrial species are more mobile, with adults migrating to breeding pools in spring and returning afterward, and with large numbers of juveniles dispersing to new habitats in late summer.

These seasonal movements put frogs at risk when roads or construction sites block their routes. Such barriers fragment habitats, increase mortality from road traffic and site activity, and may also involve the loss or relocation of breeding ponds. Fencing can help by guiding frogs away from dangerous areas and toward newly created breeding ponds, while also allowing for population assessments before development begins.

Used alongside tunnels and other mitigation measures, well-designed fencing can reduce deaths without interrupting the natural life cycle. Poorly designed fencing, however, is often ineffective, as frogs may climb over it, pass through gaps, or become entangled.
