Porcupines defend themselves with quills rather than speed, which means they don’t need to hide the way a fox or bobcat does, and Wyoming’s 196 records spread fairly evenly across Grand Teton, Yellowstone, and Medicine Bow National Forest, with smaller counts reaching Devils Tower and Seedskadee, wherever forest or riparian trees give this animal bark and buds to feed on.
Records climb sharply into a July peak, more than 16 times the January low, tracking the height of summer field activity and easier detection along roads and trails. NatureServe treats porcupines as native to their Wyoming range, and occurrence records lean heavily toward roadside and trail encounters for a species this deliberate, so porcupines working deep, untraveled forest are likely underrepresented here.
