Can I destroy invasive plants in a national forest?
I just hiked up Dog Mountain in SW Washington to see the fields of native wildflowers at the top again, only this time I saw dandelions everywhere along the path. I felt the temptation to pull them, or at least cut the flower heads so they won't go to seed.
1. But am I allowed to do that in a National Forest?
2. If it's allowed, will it do any good, or is it hopeless anyway?
