ABSTRACT:
Shelves suspended in culverts allow animals to move easily and safely under a highway. The shelves can be retrofitted to any existing culvert or can be part of a new, manufactured culvert. The shelves are removable so as not to impede water movement in times of high water or flood. The shelves are adapted to encourage all animals to use them as passageways under the highway. Ramps allow animals to access shelves. The shelf floor is mesh of the less than one inch to allow smaller animals to cross comfortably. The shelves are equipped with tubes to encourage small semi-fossorial animals to cross. The tubes provide covered protection from predators. Entrance funnels direct vole-like animals toward the tubes. The culvert shelves of the subject invention encourage animals to cross under the highway so that the highway no longer poses a barrier to these animals.
