The stand of trees at the entrance to Radix Klima is officially listed as of historical significance. The trees are on the recently drawn-up municipal list of historic trees on private land. They include four pedunculated oaks, a weeping beech, a copper beech and a silver lime, or linden. Being on the list means the trees will enjoy extra protection from now on. They may only be felled if there are serious safety considerations or other weighty circumstances.
