In 2016, Japan chose not to remove river dams blocking giant salamanders; instead, scientists built ladderways that helped the amphibians climb past them
River dams fragment habitats, impacting Japanese Giant Salamanders and other freshwater wildlife. Scientists developed ladderways to help these amphibians navigate around existing dam structures. Step-type ladders with a side wall proved most effective for salamander movement. This innovation provides a practical conservation tool for habitat connectivity. The ladderways allow infrastructure to remain while aiding aquatic life.
