Start here: protect first, then restore

Restoration is not a substitute for protection, and planting coral is not the first step.

The field’s own evidence says most projects so far have been small and short-term. Boström-Einarsson et al. (2020) reviewed restoration efforts worldwide and found a median project size of about 100 m², typically focused on fast-growing branching corals, with roughly 60–70% survival where survival was reported, and weak, inconsistent monitoring (PLOS ONE). NOAA’s planning guide therefore starts with goals and site selection, not with a favorite technique (Shaver et al. 2020, NOAA CRCP TM 36).

The order of work

  1. Preserve what is still alive (MPAs, enforcement, herbivores, bleaching preparedness).
  2. Clean the water and the watershed, or outplants will fail.
  3. Restore populations with gardening, microfragmentation, and larval reseeding.
  4. Regenerate resilience with genetic diversity and climate-ready stock, only inside a clear ethics and permit frame.
  5. Create new structure only where the substrate itself is gone (rubble, bare sand, engineered frameworks), never as decoration.

The ten Reef Zones

How the Reef Zones connect

Climate action & bleaching plans  →  Water quality & watersheds
        ↑                                      ↓
Community, tourism & livelihoods     Herbivores, fisheries & MPAs
        ↑                                      ↓
Education & local partners           Stable substrate & new structure
        ↑                                      ↓
Monitoring & adaptive management  →  Larvae, genetics & nurseries → Outplanting

A change in one Reef Zone changes the others: poor water quality shrinks the value of a nursery; a well-enforced MPA raises the odds that outplants spawn and seed nearby reefs; tourism without moorings can grind both down.

About Reef Tribe

Reef Tribe is a conservation-led reef project for the whole Philippines, focused on research, conservation and education, from northern Luzon and the Verde Island Passage to the Visayas, Palawan, the Sulu Sea and Mindanao. It is in planning: no permits, partners, sites or opening dates are announced. Read About Us →
