This book focuses on current preservation efforts of cultural landscapes within the United States. Five examples of United States National Parks are evaluated to discuss the advantages and disadvantages of re-nomination of these sites from Natural Sites to Cultural Landscapes, within UNESCO. The parks discussed include, Yellowstone, Grand Canyon, Glacier Bay, Yosemite and Hawaii Volcanoes. This research will conclude with a set of recommendations focusing on steps these parks can take to further protect their cultural landscapes under UNESCO.
