In many places, they have those bridges or tunnels for big animals, but not little ones. And, you can't coral a Porcupine, but I did make a pet of one, but he refused to come out of that tree, so I had to take his leash off.
Do you know what it costs, and takes to get a bridge or tunnel? In BC, Canada, I encountered something close to my heart, Turtle migration. A big boy pond on the right, and a girl pond on the left, and 100 turtles crossing a highway every year and not even a warning sign. And people go out of their way to hit them on the shoulder. Not even a sign or speed reduction from full highway speed. I wrote some minister at the time, Natural Resources or such, about what I saw on one day, maybe 50 turtles squashed. Heartbreaking
