BIG ISLAND (HawaiiNewsNow) - After three years of construction, crews have completed work on a five-mile long fence in Hawaii Volcanoes National Park to protect the endangered Hawaiian Petrel from feral cats.
The Hawaiian Petrel are birds that next on the ground in lava rock on the slopes of Mauna Loa. They are also defenseless against predators.
The fence is more than six-feet high and has a curved top section to prevent cats from climbing over it.
It protects more than 600 acres of the Uwau nesting habitat on Mauna Loa.
