Forest Restoration on Kaua’i

At one time in Hawai‘i, dry forests occupied much of the leeward lowlands of all the main islands and were rich in native tree species. But they were nearly all eliminated by agriculture, livestock grazing, and development by the 1950s. Less than 10 percent of Hawaiian dry forests remain today as scattered remnants in only a few leeward sites across the state.

On Kaua‘i the Lāwa‘i Forest Restoration Project run by NTBG is innovative and strategically significant By developing a dry forest restoration site, we are creating a habitat for at least 100 native plant species that can eventually be planted there. Many of these species are threatened with extinction and no longer have a viable home in the wild on Kaua‘i. The site of this restoration project is located directly below the NTBG Headquarters on the west slope of the Lāwa‘i Valley. The site is approximately 10 acres. Introduced species of brush and grasses currently dominate the area. When completed, the restored site will feature three to four distinct dry forest types based on variations once found throughout Hawai‘i. We will achieve these variations utilizing Kaua‘i species only. The forest will contain mixed assemblages of tree species with individual species grouped in small stands.

Restoring Hawaii's Endangered Tropical Rainforest

Many of Hawaii's ecosystems have become endangered as a direct result of human activities such as agriculture, timber extraction and construction. Introduction of feral pigs has had a devastating effect on the island ecology, destroying the tropical rainforest understory and allowing highly competitive alien species to gain a foothold.

The National Tropical Botanical Garden manages the Upper Limahuli Preserve in Kauai, where some of the most pristine montane wet forest left in Hawaii can be found. The NTBG has fenced out feral pigs from the Preserve and is eliminating invasive plant species. Rare local plant species are being propagated and planted in the Preserve, restoring precious habitat for rare bird populations.
