The Hawai‘i Volcanoes National Park has completed work on a 5 mile fence to protect native birds from feral animals, especially cats. Around 75 pairs of the endangered Hawaiian petrel live on Hawai‘i Island… and make their nests in lava rock burrows. Parents take turns incubating a single egg, and sometimes forage for food in very distant places. Jessica Ferracane is the Public Affairs Officer for Hawai‘i Volcanoes National Park.
Construction in the remote location began in 2013… and was limited to months around breeding season. Its isolated location around 8,000 to 10,000 feet above sea level also slowed building efforts. The 6 foot high fence has a curved top that prevents other animals from entering into the 600 acre area. National Park Service officials say it’s most likely the largest fence of its kind in the US.
