The kelp plant is "anchored" to the seafloor by a root-like structure called a holdfast. Dense stands of canopy-forming kelp are known as kelp beds or, if they are particularly large, kelp forests. The fish that depend on kelp forest for spawning, insects who live among the kelp beds and shorebirds who feed on the kelp beds have all suffered from the purple urchin overpopulation.

Cynthia Catton was among the first marine scientists to witness the collapse of Northern California’s bull kelp forests, a decline that resulted in vast barren areas on the seafloor, piles of empty abalone shells, and the closure of abalone and red urchin fisheries and, finally, of the North Coast’s last diving shop. Two kinds of kelp grow on the eastern Pacific coast: giant kelp (Macrocystis pyrifera) and bull kelp (Nereocystis leutkeana).
