Our Goal: vibrant reefs and thriving communities

Our Goal

Vibrant Reefs and thriving communities

OneReef aims to support ocean climate resilience by creating one ocean kinship to sustainably conserve and protect the biodiversity of reefs and island ecosystems across the Pacific.

OneReef By the Numbers

OneReef has been working in the Pacific for
15
years.
OneReef has
4
supporting pillars: traditional governance, traditional learning, surveillance and compliance with spatial management, and impact monitoring.

Acres managed by community partners

The total EEZ our community partners are collectively responsible for is
~2x
bigger than the world’s 10 largest MPAs combined.
OneReef has *supported or ^engaged over
50
local communities across
7
Pacific Island countries. *supported means provided financial, operational, and capacity building assistance ^engaged means expressed interest in partnership, with initial meetings held

Marine Impact

OneReef partners with the Scripps Institution of Oceanography to use scientific technology to measure reef health for many of our community partners. Together, we train and support local organizations on how to use large-area imagery technology to photodocument changes on coral reefs.

Kirino Oplet from the Conservation Society of Pohnpei utilizes the large-area imagery technology during a training with Scripps.

  With this powerful tool, we are able to create high-resolution and detailed snapshots (also called orthosmosaics) of coral reefs.

Over time, we can observe the growth (blue) and loss (red) of coral reefs by overlapping orthomosaics from different time points.

This is an example of overlapping reef images from 2017 and 2022 for Sonsorol, one of OneReef’s community partners in the Republic of Palau.

We are also able to create 3-D flythrough videos that provide an immersive view of how coral reefs change over time.

This is an example of a 3-D flythrough video that was created for Ant Atoll, a UNESCO World Biosphere Reserve.

OneReef community partnerships produce
more productive reefs

OneReef Community Partnership areas have 1.75 to 2.2 metric tons of fish biomass vs .75 tons in areas with no community partnership.

Independent, peer-reviewed research indicated OneReef Community Partnerships have higher biomass of important fish than adjacent areas outside the One Reef Community Partnerships and that our no-take areas have even more fish.
