On Friday 13 March 2026, natur&ëmwelt, a leading nature conservation NGO in Luxembourg, published an appeal urging drivers to remain cautious on the roads as the toad migration season nears its end.
According to natur&ëmwelt, although the main migration season is gradually coming to an end, increased migration activity is still being observed. With evening temperatures between 5 and 10°C and damp weather conditions, many toads continue to make their way to their breeding waters.
Under these conditions, the animals leave their winter habitats and migrate between dusk and the early morning hours towards their breeding sites. As a result, numerous toads may still be crossing roads in the coming days and weeks, the organisation noted.
Seasonal timing also plays an important role: toads have an internal biological clock that prevents them from starting their migration too early in the year. Although the peak migration period usually occurs in March, late migrations can continue into spring, particularly when weather conditions remain favourable, natur&ëmwelt explained.
Due to their slow movement and tendency to migrate in large groups, toads are particularly vulnerable when crossing roads. As few as ten cars per hour can kill around 30% of the toads attempting to cross a road, the organisation warned.
Drivers are therefore urged to reduce speed and remain particularly attentive, especially in the evening and at night when amphibians are active. Careful driving can make an important contribution to protecting these animals, natur&ëmwelt added.

The map highlights areas where amphibians regularly cross roads. Road users are asked to drive with particular caution and attention in these zones, the organisation said.
In addition, numerous volunteers take part each year in helping to safely guide toads across roads during their migration in order to protect them from traffic.
Natur&ëmwelt and its various sections across Luxembourg regularly seek volunteers who would like to participate in such initiatives.
