> There are lots of environmental groups who closely monitor the land, and will file a lawsuit if they suspect you are developing on the land. Fighting lawsuits is part of the risk.

Unless you intend to develop the land the risk seems pretty acceptable.

Only if you assume those 'environmental groups' are true to their cause and not running a shakedown operation (like e.g. the SPLC does in another politically contentious area) where they'll start accusing you of developing on your land if you don't pay them some contribution/fee/bribe.
