For the last several years, trying to avoid mass killing of amphibians on a road, ecologist from Veisiejai Regional Park Irma Maciulevičienė used to carry amphibians during the spring migrations. A system of temporary fences and dug in land buckets was built along a busy regional road Veisiejai – Lazdijai which fragments amphibian habitat leaving Šlavantas lake on one side and swampy wetlands on the other. Thousands of amphibians were trapped in the buckets while trying to cross the road.  Some of them were still managing to climb the temporary fences and were squashed on the road. To prevent amphibian road kills, the first underpass devoted for this group of animals was built in Lithuania. The pictures of the underpass can be found here.
