Conservationists are relieved that migrating animals are using the recently-built overpasses on U-S Highway 191 near Pinedale. The highway cuts across major wildlife migration routes, and vehicle collisions with animals have been a problem in the area for years.
The Wyoming Department of Transportation finished six underpasses and two overpasses for the wildlife last year, inspired by similar structures in Banff National Park. They were the first ever built for pronghorn antelope, which can't jump roadside fences, and they avoid enclosed spaces.
Each year, millions of dollars are spent controlling invasive species in Wyoming. Just about every agency you can think of is involved – from local weed and pest districts, to the Department of Game and Fish, and even the Bureau of Land Management. Many people see their efforts as an important way to protect Wyoming’s diversity. But others worry that removing invasives could sometimes do more harm than good.
