Mars Coral Reef
Restoration

Section 3

Impact Below Water

Working with local communities in Indonesia, we have rebuilt 40,000 square metres of reef in the most biodiverse seas on the planet.

Before and after

At its most effective, the MARRS method can transform heavily degraded rubble fields into healthy coral-dominated ecosystems within a few years. Drag the slider below to see this for yourself, comparing illustrative examples of a degraded rubble field and a nearby restored reef, 3 years after Reef Star installation.

Degraded rubble field,

<5% live coral cover

3 years post-restoration,

>60% live coral cover

Use the slider to see the difference yourself.
