Reefs made from trees could help restore biodiversity, study finds

Researchers say their pyramid-shaped pear tree structures could help certain marine habitats recover

Reefs made from sunken trees can help restore biodiversity in degraded marine habitats, scientists have found.

It is estimated that coral reefs support about 25% of all marine life. They provide housing, food and areas to spawn for millions of marine species and are the backbone of maintaining the aquatic life cycle.
