Description
Six researchers led by Kyle Joly studied how a lone mine road in northwest Alaska affects caribou survival. The eighty-kilometer road links a zinc and lead mine to a port, crossing the herd's fall migration path. The team tracked three hundred sixty-six collared females over more than a decade, gathering movement and survival data.
Over half the caribou that neared the road changed their movements. Those that crossed or went around survived to calving at a far higher rate than those the road turned back. Animals whose paths changed also fared a bit worse overall. The authors argue that roads wildlife can cross more easily would lift survival.
