A conservation easement is valid even though:
(1) it is not appurtenant to an interest in real property;
(2) it can be or has been assigned to another holder;
(3) it is not of a character that has been recognized traditionally at common law;
(4) it imposes a negative burden;
(5) it imposes affirmative obligations upon the owner of an interest in the burdened property or upon the holder;
(6) the benefit does not touch or concern real property; or
(7) there is no privity of estate or of contract.
