Transcript of Wildlife Crossings
55,650,943 miles of road in the US
Approximately 10,000 miles of new roads built in the US per year Additional 7-8% only
Made up in decrease in property damage Wildlife Crossings Do animals actually use them?
Do they actually work? Based on population density
Should base on movement
Random placement Anthropocentric
So do they work? By Madeline Scott and Marissa Cameron Process to get a Crossing 1. Determine if crossing is needed
2. Identify the species that needs it
3.Determine which type of crossing is needed
4. Sufficient land and resources?
5.Cost of maintenance
6.Is it efficient? How Roads Impact Populations 1. Decrease amount and quality of Habitat available
2. Mortality rate increases due to vehicle collisions
3. Population is restricted to resources on other side of road
4. Divides populations into smaller sub-populations, this leads to sickness if the gene pool gets to limited Road Kill Approximately 253,000 animal vehicle accidents
Average of 200 humans dying annually
$2,000 to get a vehicle fixed after a collision Conclusion Types of Wildlife Crossings Large Mammals
Butterflies and birds
