Puu Makaala Natural Area Reserve
Puu Makaala Natural Area Reserve is 18,730 acres in size and was established in 1981 to protect unique native rainforest. Long-Term management of this forested watershed provides multiple benefits including protection of the island's water resources, undeveloped open spaces, and culturally significant areas. The reserve provides habitat for rare native plants and animals preserving the biodiversity of Hawai'i for current and future generations. This wet forest contains many large old ohia trees, false sandalwood trees, and towering hapuu tree ferns. Fenced areas are open to the public; fencing is just excluding the animals from the area. Gates and walk-overs allow people to access these areas. The rainforest trails are usually muddy, so waterproof boots are suggested.
