I specifically want to know if it is legal to plant food plots on public lands. But the complete rules and regulations on food plots would be even more welcome.
It is illegal to plant any type of foodplot on public lands without the permission of the land management agency responsible for the property. I am unaware of any occasion in which a public land management agency has given approval to a private individual to plant a food plot on public lands, so I do not know the likely hood of this being successful.
Additional items to take into consideration when dealing with foodplots are ensuring they are managed in a way that does not conflict with state or federal baiting laws, or promote or introduce noxious or invasive weeds/species.
