We can't collect from any state owned land. Because it's owned by the state! I guess they send people out to assess the populations of flora and fauna on the land in question, and determine if there are any species that need to be relocated.
I had to stand by and watch a stand of a particularly endangered sub-species of a plant called puzzytoes get plowed under last Spring because I couldn't get permission from the landowner or state to collect. It was on the roadside, and there was a dispute as to who owned the plants. It was a big bummer. Kinda broke my heart.
Puzzytoes is not really the name of the plant. actually the z's should be s's.
