Weeks talks about tradable conservation easement for vulnerable conservation objectives. The critical conservation objectives in some conservation easements will probably be compromised by the effects of climate change in the relatively near future. Conservation easements broadly intended and drafted to serve those kinds of general purposes are, as a group, unlikely to be so acutely affected by changing ecological conditions that their broad purposes will cease, over time, to be served.
