 Hili is a terrestrial field site located 100 miles southwest of Fairbanks by Denali National Park and Preserve in Alaska. This neon field site covers a little more than 45 square kilometers and is part of the largest boreal forest biome on earth, covering 17 million square kilometers. It features a 26 foot tall flux tower with a customized boardwalk for dog sled crossing. It also features defined plots for vegetation, soil, bird, mammal and insect sampling and observations. Hili is experiencing widespread permafrost thawing, making it a valuable resource of information to understand how other permafrost systems in Alaska will experience and react to thawing in the future.
