The Ka`ena Point Ecosystem Restoration Project was the result of a
partnership between the Hawai`i Department of Land and Natural
Resources, Divisions of Forestry and Wildlife and State Parks, the U.S.
Fish and Wildlife Service, and the Hawai`i Chapter of The Wildlife
Society. Ka`ena Point Natural Area Reserve (NAR) hosts one of the
largest seabird colonies in the main Hawaiian islands, three species of
endangered plants, and is a pupping ground for the endangered Hawaiian
monk seals. Prior to fence construction, nesting seabirds and native
plants were under constant threat from predatory animals; up to 15% of
seabird chicks were killed each year prior to fledging and many
endangered plants were
unable to reproduce as a result of seed predation. The project involved
the construction of predator-proof fencing (2m tall) to prevent feral
predators such as dogs, cats, mongoose, rats and mice from entering into
20ha of coastal habitat within Ka`ena Point, followed by removal of
