Potential effects of highway mortality and habitat fragmentation on a population of painted turtles in Montana E9CBC35D-17E7-4C00-9213-03EFBB0C4692 Year: 2006 Concrete Walls The Payne's Prairie Ecopassage project near Gainesville, Florida has incorporated the dual-use (hydrological leveling and wildlife crossing) culverts and barriers which have been successful in providing connectivity for a wide range of terrestrial and aquatic wildlife. This project has the most pre- and post-construction data available of any wildlife crossing culverts and directional barrier project (Barichivich and Dodd 2002). A suite of structures including lipped concrete walls, concrete square box culverts, precast concrete bottomless culverts, round concrete pipes, open median drains, and reverse mount guardrail barriers (Type A fencing, see next section below) combine to reduce mortality and allow animals to cross under the highway. The concrete wall with a lip keeps small mammals, reptiles, and amphibians off the highway (Figures A-7 and A-8). The concept of a lipped wall can be used in any area where barrier fence for small animals (reptiles, amphibians, small mammals, or even flightless stages of birds such as ducklings) is desired. The height of the wall can be based on whatever species are in the area of concern. Because the Paynes Prairie project had species that were able to climb high walls, it is likely that most situations would need shorter walls. Figure A-7.
