From Mountain to Sea
Maui Nui includes the Hawaiian islands of Maui, Molokai, and Lanai, and the reefs in this region are a very important resource. This is because of the high coral cover and connectivity via currents. More interestingly, this area boasts unique species of corals that can only be found in this area.
Our Maui Nui team works with partners to restore ecosystems to improve the health of these reefs.

Restoring Watersheds for Clean Water
In West Maui, we partner with Kipuka Olowalu to restore natural filtration processes within watersheds. This prevents land-based pollution from harming reefs. High levels of sediment runoff smother corals, reducing their access to sunlight and slowing their growth. Excess nutrients fuel algal blooms, which can outcompete coral and promote disease.
Using a ridge-to-reef approach, we work to restore the natural function of ahupua‘a—Hawai‘i’s traditional watershed management system—by stabilizing stream banks, replanting native vegetation, and improving water filtration.
In Olowalu Valley, we are monitoring sediment movement, identifying erosion hotspots, and testing the effectiveness of native plants in preventing runoff. These efforts help ensure cleaner water flows from the mountains to the reefs.
Sustainable Fishing Through Fishpond Restoration
In Molokai, traditional fishponds have provided a sustainable food source for generations. However, sediment buildup, invasive species, and land mismanagement have disrupted these ecosystems, reducing fish populations and harming water quality.
We are working with Ka Honua Momona to revitalize these fishponds by:
- Monitoring water quality to track improvements in reef health.
- Clearing excess sediment to restore their depth and productivity.
- Removing invasive species that disrupt the balance of the ecosystem.
- Planting native vegetation to stabilize shorelines and prevent erosion.
By restoring fishponds, we are not only supporting sustainable fishing practices but also strengthening the connection between land and sea—ensuring healthy reefs and marine resources remain for future generations.
