The Department of Land and Natural Resources (DLNR) has announced new measures to protect the watersheds of West Maui, ensuring the preservation of both human and environmental health. The installation of new fencing and upgrades to existing fences in the Puʻu Kukui Watershed Preserve and TNC's Kapunakea Preserve will prevent the entry of invasive hoofed animals, safeguarding the vital freshwater resources of Hawaiʻi.
The importance of protecting these priority watershed forests cannot be understated, as they are the sole source of fresh water in the region. By implementing these measures, native plants, including rare species, will be able to thrive, leading to increased water recharge, reduced erosion, and decreased potential health risks for downstream users. Additionally, the protection of these watersheds is crucial for the preservation of Hawaiʻi's coral reefs, which can be smothered by sediment runoff.
The Puʻu Kukui Watershed Preserve, situated on the west side of Mauna Kahālāwai, is one of the largest privately owned nature preserves in Hawaiʻi. With an average rainfall of nearly 400 inches per year, it is one of the most pristine and intact habitats in the region. The preserve is managed through a collaborative effort between the preserve's staff, Maui Land & Pineapple Co., DLNR, and with support from The Nature Conservancy (TNC) and the Living Pono Project. While previous projects had focused on the Kahana and Honolua watersheds, the new work under this initiative now provides a contiguous fence line, offering enhanced protection for the water resources in the area.
The Kapunakea Preserve, located in the Honokōwai watershed, is managed by DLNR and TNC. It serves as a habitat for 11 different natural communities and is home to 24 rare and endangered species. Project funds were utilized to support the installation of fencing and management activities aimed at safeguarding biodiversity, cultural resources, and water resources.
Chris Brosius, the program manager for the Mauna Kahālāwai Watershed Partnership, expressed gratitude and appreciation for the completion of the fencing project, stating, "Building these long-needed sections of fence helped us solidify and renew the protection we can offer our mauna. It's been years in the making, and we are excited to have completed the project." The challenging terrain required advanced skills in building and rappelling, making this achievement a testament to the dedication and perseverance of the staff involved.
In addition to its immediate benefits, this project also contributes to the advancement of the West Maui Ridge to Reef (R2R) Initiative. This holistic approach, involving multiple organizations, aims to protect the coral reefs in West Maui. By keeping the upper watershed free from invasive deer, pigs, and other hoofed animals, vegetative cover is maintained, reducing erosion and sedimentation that can negatively impact the nearshore reefs. Furthermore, the healthier forests in the area may contribute to increased fresh water production and mitigate the effects of future droughts.
The DLNR's efforts to protect the West Maui watersheds are vital in ensuring the sustainability of both the environment and the communities that rely on these resources. By implementing effective fencing measures and promoting collaborative management, the DLNR, along with its partners and stakeholders, is taking significant steps towards preserving the natural beauty and ecological integrity of West Maui.
