NFWF Coral Reef Conservation Fund: Maui Nui
Reducing Pollution to Protect Coral Reefs in Honokōwai
Project Summary
Maui Nui, meaning Greater Maui, encompasses Haleakalā, West Maui, Kaho'olawe, Lāna'i, East Moloka'i, West Moloka'i, and Penguin Bank. We are working with partners at three priority sites in Maui Nui: Honokōwai, Kihei, and Lana’i to address specific local threats to coral reefs. Together, we will design and implement practices that reduce impacts on coral reefs from land based sources of wastewater and sediment pollution. Working with management and local partners we are designing best practices, piloting new approaches, and planning for future reef resilience.
In Honokōwai, sediment erosion is one of the biggest threats to reef resilience.
Problem
Coral reefs are damaged by sediment flowing from the land. In Honokōwai and Lana’i, substantial sediment erosion is clouding coastal waters and harming the coral reef.
Solution
In Honokōwai and Lana’i, stabilizing eroding soils is key to protecting the reefs. This has implications for the survival of the coral reefs, as well as the health and resilience of the communities that rely on the coral reefs.
Implementation
Honokōwai: 1) Restore eroded road kick-outs with native plant and vetiver grass sediment traps 2) Improve water filtration to remove sediment particulates at the Honokōwai Dam
Outcomes
Stabilizing eroding sediments and providing safe, natural wastewater treatment alternatives protects human communities, protects groundwater, and protects coral reefs. Reducing these stressors help the environment recover, thrive, and be resilient.
