From the identification of special places for natural areas in the 50’s to the 70’s, to knowledge of where rare imperiled and endangered species occur in the 70’s, 80’s, and 90’s, to landscapes and locations needed to assure that we retain the now agreed inadequate 10%, to Potential Natural Areas in the 2000’s, to their connectivity in the face of climate change, we now know that the job of conservation is enormous. Do we have the tools? Can the most successful groups get the job done?
