Guy. I'm not just trying to argue with you. I almost always agree with you on topics. And I agree with alot of what you just said about lots of solutions. There is...but I dont think you are hearing the message.
There is alot of information coming to light regarding ungulate migrations. And other western states are taking action to protect migration corridors because of the MASSIVE effects it can have on herd health. These corridors we speak of, THEY ARE THE HABITAT! And generally have been so necked down and intruded upon that narrow bands are all they have left for unfettered movement. They now have evidence of mule deer migrating nearly 250 miles from South WY into Idaho. Alot of ND goats travel south out of state in the winter. As the article states from NDGF, the pronghorn north of I94 have a hell of time making it south. Why do you think their populatinos are so vulnerable to winter? Seasons opened one year, closed the next. Its because they can't get from point A to point B.
It sounds like you are okay with the status quo. "Learn to live with fences or die!" Yes we live in a changing world, but some animals have trouble adapting to certain things. If you dont care about increasing the health and sustainability of the pronghorn heard thats fine. But the facts aren't on your side. Highways and fences are a huge factor for pronghorn, in particular. We can discuss every species on its own merits if you would like because each are unique. But dont be the old grumpy guy in the room who won't listen to whats being presented and consider it rationally. Just because you saw a pronghorn cross a fence just fine 30 years ago doesnt mean they dont pose a significant obstacle throughout their life cycle. Connectivity is a crucial thing when discussing wildlife populations.
Again, i'll end by saying this isnt us dog piling on you. We all respect you. Maybe take a second to pause and read up on recent ungulate migration research. These critters dont live in a finite box. They need room to roam and seek out food, water, shelter, and space. Those things move on the landscape from year to year. Getting killed in pursuit of them doesnt help anyone. Ecosystem or humans/safety problems. If we're preaching it, and other state governments have thought it a worthy endeavor, maybe there is something to it?
I understand if you dont agree with $7M underpass as solution. But there is a problem with collisions. And these have been proven to work. You just would rather pursue other solutions. Fair enough...
