Crayweed once formed dense beds on shallow reefs along the Sydney coastline. These underwater forests have become locally extinct, causing detrimental repercussions for native fish, abalone, crayfish, and coastal marine biodiversity. Crayweed is among the most important ecosystems on the planet, providing critical food and habitat for hundreds of species. These vast underwater forests support coastal food webs, sequester immense amounts of atmospheric carbon, produce oxygen for marine life, and support unique coastal biodiversity, which is not supported by any other seaweed species.
