Kelp Restoration

Project Restore, in collaboration with Operation Crayweed aims to increase the resilience of local golden kelp (Ecklonia radiata) forests using some of the lessons learned from Operation Crayweed.  

Kelp forests are among the most important marine systems, providing critical food and habitat that supports hundreds of species. Like trees on the land, seaweeds form vast underwater forests that underpin coastal food webs, capturing atmospheric carbon and producing precious oxygen.

Project Restore takes a slightly different approach by conducting passive restoration, whereby we reduce the impact from predators rather than replanting. In a balance ecosystem we see a mosaic of barren and kelp forests.

In urbanised environments where fish biodiversity is compromised this system can become unbalance causing community dynamics to shift. In areas where predators have declined due to overfishing, sea urchins can rapidly expand, overgrazing kelp forests and contributing to the loss of this habitat, transform it into barrens.

This part of Project Restore focuses on passive restoration whereby the ecosystem has become unbalanced urchins are removed from barrens to give the kelp the best chance of survival.
