Federated States of Micronesia

Senipehn Community


Conservation benefit: Permanent protection of 2,718 acres of upland forest, mangrove, seagrass, and coral reef habitats

Community benefit: Water tanks and pipes to provide clean water to every household

Date Approved: 06.2022


This project protects forest, preventing the release of greenhouse gases and reducing erosion that damages coastal and ocean ecosystems.


This project protects mangroves, which trap more CO2 than any other kind of forest and as a result, slow global warming.


This project protects ocean ecosystems, making coastal communities more economically and physically secure in the face of climate change.


This project protects seagrass, which traps more CO2 than any other marine ecosystem, slowing global warming.

Pohnpei is a mountainous, forested tropical island, part of the Federated States of Micronesia. The FSM is just a speck on the map of the central Pacific, but it contains some of the most important ecosystems on the planet, including rainforest, mangrove forest, seagrass meadows, and coral reefs. This project would protect all of those habitat types.

The area has more than 200 species of native plants, including seven species of mangroves, which provide a nursery for mangrove crabs and many species of fish. Birds are abundant, including the critically endangered Pohnpei starling and the vulnerable Pohnpei kingfisher.

The Senipehn Community comprises five villages (Nankepira, Elielwi, Diadi, Pohnauleng, and Sapwehrek Kep), with a total population of about 1,800. More than 70% of them are farmers or fishers who do not make a regular salary.

Senipehn’s traditional leaders and residents have committed to protecting the community’s entire forest watershed. They will also protect mangroves, seagrass beds, and reefs. The upper forests and stream headwaters, which cover about 700 acres, will be strict no-take areas. In a lower 1,000-acre area, local people will continue to practice traditional agroforestry, as they have for an estimated 2,000 years. The mangrove and seagrass areas and reefs, which cover another 1,000 acres, will be no-dredging zones. Subsistence fishing will continue around the reef.

The five traditional leaders, with community conservation officers, Senipehn Youth Organization members, and landowners, will develop a watershed management plan that will be codified in a municipal ordinance. The Madolenihmw Municipal Police will provide enforcement as necessary.

Working with the Micronesia Conservation Trust, a Seacology grant is funding a water storage and supply system that will supply clean water to every household. The community is one of the least developed in Pohnpei, and most households do not have regular access to safe drinking water. Unsurprisingly, this leads directly to ongoing public health problems, especially for children.

Project Updates

February 2024

Community members installed the water tank and posted new signs in the mangrove reserve. The forest and marine areas remain under protection, and the community plants to pass a municipal ordinance to protect the watershed.

June 2023

The community has prepared the site for the water tank and poured concrete. Community conservation officers will get training in compliance and enforcement of the mangrove reserve. Meanwhile, our project partner reports that people are aware of the conservation agreement and are abiding by its terms: “The five village chiefs are making sure of this.”

February 2023

A municipal ordinance to protect the Senipehn Watershed area was drafted and scheduled to be introduced in the January 2023 legislative session. All water pipes and fittings for the water system have been bought and delivered to the site. In January, the construction company was scheduled to prepare the site for the water tank. People in the larger Senipehn community are excited because several of the five villages have never before had running water.
