State of Wisconsin Forests, you can get permits for State Forests. Because state forests are designated for lumber harvest at some point. Ask about a permit for 10 or less plants for landscape. (the number may be 10, it might be 7 I have not checked lately.) Do the asking at the ranger office of the forest where you want to collect.
State Parks - zero collecting - as these are for recreation, Wildlife Refuges, Wilderness Areas, Natural Areas, and other "Preservation" designated areas no permits will be available.
You should be able to get permits for collecting in Chequamegon-Nicolet State Forest, or Black RIver State Forest, or Northern Highland American Legion State forest. Generally I recall not seeing many larch until you are about as far north as Stevens Point. So you likely have to "go north". In southern Wisconsin, larches will likely be restricted to bog habitats, which where they occur, will likely be protected areas. Once you are far enough north, the larches are everywhere, including roadside ditches.
