For my final project of my Masters Degree at the University of Denver I helped the Dean of the law school better understand the state of conservation easements in Colorado.  The focus was to identify attributes of existing easements that could potentially be vulnerable to law challenges given climate change may change the easements primary purpose.  For example if an easement was put on a property for a particular endangered species and climate change created a scenario where that species would not naturally live in that area then the argument could be made that that easement was no longer relevant and could be removed.
