What is exclusive control lease?

I use the internet and a handheld gps with the land ownership package. When ever myself or friends set up hunting trips, we do our homework to stay on as much public land as possible. But when I read the F&G rule book it mentiones "exclusive control lease", what is this? And how does one find out which blm lands fall under these special rules? It is hard to follow such gray rules if one doesnt explain them better.
Answer: 
Exclusive control lease lands are either state or federal lands leased primarily for geothermal, mineral, gas or oil exploration, solar, or other uses where public access and use is not allowed as a condition of the lease.  Such areas/sites are relatively small and limited when compared to all public lands.  It is unlawful for anyone to post public land that is not held under an exclusive control lease. Additional information and Idaho BLM field office contacts can be found at: http://www.blm.gov/id/st/en.html.
