LNT is a regional thing in how you practice it. In the West you can see a 10 year old set of footprints in some places.

Here in the Ozarks, well used trails get swallowed up in a few years of no use. Therefore, the trail is often considered a blight, and using one discouraged in some areas.

There are generally no laws against collecting food from the forests. There are some highly regulated plants. Ginseng and Purple Coneflower among them. There are many other wild plants, fruits, and herbs that locals collect each year though with no ill effect on the ecosystem.
