1 Specifications and Details for Wildlife Measures Wildlife Contracts Branch

2 Cuts off migration corridors Partitions population into smaller gene pools Blocked resourcesFragmentation

3 Wildlife-Friendly Fencing General Notes 1.Intermediate Post Assemblies shall be located as shown and at intervals not to exceed 50’ or midway between all braced posts 2.For game fences the bottom wire shall be barbless. 3.The stays on game fences shall have their ends turned up to prevent injuries to game.

4 Wildlife-Friendly Fencing: Ungulate PVC

5 Wildlife-Vehicle Collisions 1-2 million large animals killed per year in the U.S. >100% increase over the last decade >200 human fatalities per year in the U.S. 1 million vertebrates killed per day in the U.S.

6 Completion of Crosswalk & Fencing 97% Reduction in Elk-Vehicle Collisions

7 Standard Ungulate-Exclusion Fence

8 Cattleguards

9 Escape Jump-Outs

10 Tortoise-Exclusion Fencing http://www.fws.gov/ventura/species_information/protocols_guideline s/docs/dt/dt_fieldmanual/CHAPTER%208.pdf

11 Culverts Bigger is better for diversity and functionality Design should include a natural substrate whenever possible Ends, including energy dissipation measures, should not prevent utilization by smaller species

12 Underpasses Work better than culverts for most species due to the added openness

13 Overpasses Work best for virtually all species due to maximized openness
