Adorably fuzzy sea otters aren’t just cute. The marine mammals serve a crucial role, helping to restore the giant kelp forests they rely on by removing their top predators, the sea urchins.

The kelp forests provided habitat, nursery and feeding grounds for marine wildlife, and held huge quantities of carbon, improved water quality and reduced coastal erosion, campaigners said.

When sea otters were reintroduced along the coastlines of islands in Southern California and British Columbia, researchers saw kelp forests return to areas that were destroyed by sea urchins.

"But there are huge implications for the coast." Forests of kelp, a fast-growing brown algae, provide food and habitat for hundreds of marine species and absorb greenhouse gases that might ...
