The Problem

Ulupō Heiau and its surrounding areas are an extremely important part of Hawaiian history and culture. It is the one of the oldest and largest heiau (temple) of its kind on Oahu, and its easy access makes it convenient for tourists and locals alike to visit and appreciate its beauty and significance. The site is of great historical and cultural value to Native Hawaiians and serves as a hands on educational experience to Hawaii’s students and other groups who often come to volunteer at the site. It’s also an important tourist attraction with bus loads of tour groups visiting the site each day. The adjacent Kawainui Marsh is equally if not more important because of its place on the Ramsar List of Wetlands of International Importance making it a place of high value to people around the world. While Ulupō Heiau may be welcoming enough for large tour groups to visit, a lot still needs to be done to restore Ulupō Heiau and its adjacent land to the way it was when the ancient Hawaiians used it as a place of worship. The walls of the lo’i (taro fields) and auwai (irrigation channels) need to be rebuilt and maintained. Invasive species also quickly take over the lo’i and auwai restraining the water flow and smothering the Hawaiian taro. The adjacent Kawainui Marsh is also almost completely covered in a floating mat made of invasive species like California grass and cat tails. This creates a smelly mess of mud, rotting plants, and stagnant water, which prevents native Hawaiian wetlands birds from gaining access to the water and native plants from growing.

Plan of Action

This has been an ongoing project to restore Ulupo Heiau and Kawainui Marsh to their original states during the time of the ancient Hawaiians. Currently ‘Ahahui Mālama I Ka Lōkahi has been working mostly on clearing the lo’i, auwai, and wetland bird habitat of invasive species and building the walkway around the habitat. We are using the wetland bird habitat as an example of what can be done to restore the marsh in hopes that we will be able to receive more money to continue our efforts. So far we have successfully cleared out four lo’i and parts of the auwai of invasive species and we’re working on a fifth lo’i and the rest of the auwai. Thanks to many volunteer groups we’ve also managed to build about 600 feet of the walkway around the bird habitat and have cleared out enough of the invasive species and mud to expose a large water surface area. Our efforts have been so successful that the Hawaiian stilt has started to nest in the wetland habitat we’ve created and a few other native birds also frequently visit the site.
