yes - the thread morphed over to migration and the bigger issue almost instantly - resulting in my position being painted as an "anti-animal to save-money" position, while that's not me at all
I am in 100% agreement that general migration is a huge problem - one that makes me sad like you. Antelope not being able to head to other areas easily (I can only imagine how many miles they can put on in a day with no crossings) when it's a brutal winter where they currently are does indeed suck
my point of contention was that these underpasses aren't mass migration solvers - they solve a localized animal movement and vehicle collision issue. Crossing one highway safely is a drop in the bucket when it comes to long distance migration they might make for seasons/drought/etc. where hundreds of fences are waiting. I'd like more economical solutions so that we could implement them darn near everywhere that they'd be beneficial.
I'd be fine with trying to get all fencing somehow more critter-friendly to give the ungulates a chance. But the scale of solving the issue with any effectiveness in monstrous : (
GPS shock collars on all domestic herd animals? Ha ha ha
These greedy Fargo scientists don't care about wildlife and want to kill off all the pronghorn. You heard it here first folks
