Coral Restoration Methods

• Coral fragments are collected from healthy reefs or nurseries and transplanted to degraded areas.

• These fragments are grown in underwater nurseries before being reintroduced to the reef.

  Pros: Can help repopulate damaged reefs.

  Cons: Success rates vary, and transplanted corals are still vulnerable to climate change.

• Structures made of concrete, metal, or other materials are placed underwater to provide a surface for corals to grow.

• Artificial reefs can help restore marine habitats and attract fish populations.

  Pros: Provides new habitat and increases biodiversity.

  Cons: Can disrupt natural ecosystems if not placed correctly.

Artificial Reefs

Coral Gardening

• Scientists collect coral eggs and sperm during spawning events, fertilize them in a controlled environment, and release larvae onto damaged reefs.

  Pros: Helps maintain genetic diversity.

  Cons: Highly experimental and requires ideal conditions for success.

Coral Larval Reseeding

Micro-fragmentation & Assisted Evolution

• Corals are broken into small fragments to accelerate their growth.

• Scientists are also experimenting with breeding corals that are more resistant to warming oceans.

  Pros: Encourages faster coral recovery.

  Cons: Still in early research stages.
