Wildlife & Roads
- Barrier to Movement
- Fragment Habitat
- Cause significant mortality (healthy and weak)
- Mitigation Efforts
- Fencing
- Wildlife Vehicle Collisions (WVC) declined after
mitigation fencing was implemented despite
annual increase in traffic volumes in Banff Nat'l Park
- Ungulate mortality dropped 80%
- Safe crossing opportunities MUST be provided
- Ungulate mortality dropped 80%
- CONS
- Animals can become trapped
- Unintended Barrier Effects
- Disrupts daily, seasonal, dispersal movements
- Disrupts daily, seasonal, dispersal movements
- Animals can become trapped
- PROS
- Wildlife Vehicle Collisions (WVC) declined after
mitigation fencing was implemented despite
annual increase in traffic volumes in Banff Nat'l Park
- Wildlife Warning Signs
- Increase alertness of drivers
- Reduce Vehicle Speed
- Enhanced signs with
lights significantly
lowers vehicle speed
- Reduced speed does not necessarily mean a decrease in WVC
- Reduced speed does not necessarily mean a decrease in WVC
- Enhanced signs with
lights significantly
lowers vehicle speed
- GOALS
- PROS
- Does not restrict animal movement
- Decreased speed can lessen severity of collisions
- Does not restrict animal movement
- CONS
- Standard Signs are ineffective
- Distraction to drivers
- Contributes to Roadway clutter
- Distraction to drivers
- Standard Signs are ineffective
- Increase alertness of drivers
- GOLDEN, COLORADO
- Wildlife Crossings
- Are they effective?
- What is the method used to warn motorists?
- What is the ecology of the
surrounding landscape?
- What animals are most vulnerable?
- Are they effective?
- Jefferson County - second highest WVC incidents in
2013 with 248.
- Wildlife Crossings
- Fencing
- Mitigation Efforts
