Despite intersite variation in the abundance of kelps and herbivores, these analyses demonstrate that sea otter predation has a predictable and broadly generalizable influence on the structure of Alaskan kelp forests. Without sea otters around to eat urchins, Alaska's kelp forests and algal reefs have been left vulnerable to overgrazing. Off the California coast, lies one of the fastest growing forests in the world. Kelp Forests - a Description. Well not really. A combination of climate warming and loss of sea otters is harming the reefs that underpin Alaskan kelp forests in the Aleutian Islands. It however runs down the entire pacific coast of canada and the United States. In Alaskan kelp reefs, otter populations help to keep sea urchin populations in check. 8.) Kelp forests cover an enormous area of the Hebridean sub-tidal seabed. Rising sea temperatures have already wiped out 100 kilometres of kelp forest along the south coast of Western Australia – and this unprecedented loss looks set to worsen. In the eastern Pacific ocean, they occur from Alaska and Canada to the waters of Baja California in the northern hemisphere, and along the southern coast of Chile in the southern hemisphere. Rich in biodiversity, kelp forests grow along rocky shorelines, mostly on the Pacific coast, from Alaska to Baja, California. They provide food and shelter to thousands of animals and consist of kelp that grows 18 inches per day. According to a recent study it is predicted that the majority of Britain’s kelp forests are likely to disappear by 2100. Unfortunately, historic sea otter fur trade created intense ecosystem shifts in northern California, and now climate change has created additional serious stressors on the kelp forests. History: The Giant Kelp forest is magnificent forest located in Alaska and along the west coast of North America. “Despite the fact that the Aleutian Archipelago is remote and largely uninhabited, it nonetheless has a long history of predator exploitation, and is also at the front lines of climate change,” said Douglas Rasher. Instead almost done by one species kelp forests are destroyed in days. Kelp is very sensitive to sewage and oil. Large numbers of opaleye or halfmoon fishes can damage kelp forests, particularly when the kelp is exposed to unfavorable growing conditions. But then why aren't they being eaten at all.

These kelp forests are found in four of our national marine sanctuaries along the West Coast,and are dominated by two species: giant kelp (Macrocystis pyrifera) and bull kelp (Nereocystis leutkeana). Alaskan kelp forests occur in nearshore marine environments of the western Gulf of Alaska, Aleutian Islands and eastern Bering Sea between latitudes of about 45–60° N (Figure 2). Non-point and point source pollution including sewage, industrial disposal, and coastal runoff might contribute to kelp forest degradation. Kelp forests are a naturally resilient ecosystem: they tolerate seasonal climate changes like El Niño and endure trophic changes caused by unpredictable events (e.g., rough storms) or humans (e.g., overfishing). From 1969 to 1971, the United States was testing nuclear weapons beneath one of Alaska’s Aleutian Islands, worryingly close to some of the world’s few surviving sea otters. 2. The ecosystem we will be looking at is the Giant Kelp Forest. Numerous sessile animals (sponges, bryozoans and ascidians) are found on kelp stipes and mobile invertebrate fauna are found in high densities on epiphytic algae on the kelp stipes and on kelp holdfasts. Welcome to: Kelp Forests of Alaska!
