I'm not real versed on the subject but don't many conservation groups try to purchase land to protect habitat and such. I'm thinking of Rmef for one. Seems if these groups are on the same page as the state agencies they could really benefit one another. It could keep the state agency from getting in some sticky land purchase messes. Like I said I don't know much about it. What's your thoughts.
Groups like TNC, RMEF, etc are both purchasing lands and putting conservation easements on them. If they purchase fee title, it is usually with an eye towards selling those lands to either the state or the Federal Gov't. Other groups like MALT, MRL, etc focus on conservation easements. The US Fish and Wildlife Service also purchases conservation easments depending on location and biological need (like the Rocky Mtn Front, etc). Those easements however have no access component.
If we look at the Legacy project that Schweitzer and Baucus pushed through, a ton of federal funds were used to purchase Plum Creek lands from TNC, which were originally purchased by TNC from Plum Creek. Those purchases gave us the Marshall Block and Fish Creek state park.
Then we have the Land and Water Conservation Fund, which is used to leverage funds for fee title acquisition, new fishing access sites, etc. LWCF also helps build most of the city parks in MT. That is funded by offshore oil and gas leasing. It has accounted for a lot of good projects in MT.
In the case of APR, IIRC, they are looking at amassing roughly 3 million acres of deeded and leased public land which they would at some point turn over to the Feds so that it could be managed as public land. In fact, APR has opened up their outfit to access (300,000 acres of public and private) through block management.
