Have you ever seen a turtle fence? They are being used more frequently to cut down on roadkill in areas where highways cross the natural migration routes of turtles.

What is a turtle fence?

• A turtle fence is a physical barrier that prevents turtles from entering any area.
• Fences can guide turtles to an underpass or other safe way of crossing the roadway.

What is the need for turtle fences?

• To reduce a source of distraction and a cause of accidents on high speed highways.
• To save lives.
• To protect and preserve endangered species.

How is a turtle fence made?

• Welded or woven wire fence with a 1/2"x1" to 2"x2" mesh is ideal.
• 16 to 12.5 gauge wires are sufficient.
• Galvanized before, galvanized after or vinyl coated mesh, depending on the desired lifetime of the fence.
• 24" to 36" height depending on species.

A turtle fence can be a costly project and is often a cause of debate. Maintenance, especially in areas of heavy snow, can be quite costly if the fence is damaged by snow plows. Do you think the expense is justified?
