alaskan kelp forest

But new research finds that urchins are now tearing through more than just the kelp forests. Scientists have proven that kelp grows slower and less healthy is more toxic water and soil. They provide habitat and food for over 700 species of algae, invertebrates, and fish. In the 1980's alone, kelp harvesting supported an industry worth more than $40 million a year, and in 1993, more than 4,700 wet tons of kelp were extracted from the Monterey Bay National Marine Sanctuary. The otters feed on sea urchins, … 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). Adapted from Raffaelli & Hawkins (1996) and, Steneck et al. Especially productive kelp forests tend to be associated with areas of significant oceanographic up swelling, a process that delivers cool nutrient-rich water from depth to the ocean’s mixed surface layer. Well they do and its the sea otter. This site is in the Aleutian Islands of Alaska. In the 1980's alone, kelp harvesting supported an industry worth more than $40 million a year, and in 1993, more than 4,700 wet tons of kelp were extracted from the Monterey Bay National Marine Sanctuary. 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. It however runs down the entire pacific coast of canada and the United States. Kelp forests in the eastern and northern Pacific commonly have complex three- dimensional structure, with many coexisting species. 10.) The percent cover of algal turf and suspension feeder assemblages also differed significantly (although less dramatically) between locations with and without sea otters. By: Diana Sanchez, Anel Acosta, Arizbet Vazquez, and Clarissa Barba. 2. Approximate distribution of Alaskan kelp forests off the coast of North America, north from about 40°N. Kelp forests grow predominantly on the Pacific Coast, from Alaska and Canada to the waters of Baja California. Kelp forests grow on hard, rocky surfaces where they can tangle their root-like holdfasts around the stone. Kelp harvesting is also another concern. As in coral reefs, shading is a major mechanism of intra- specific and interspecific competition. Help the kelp. Words Max James. SAVE THE KELP! 9.) Giant kelp forests granted endangered status. (2002). Sea otters have long been considered protectors of the kelp forests, and for good reason. Central California bull kelp forests remained in cooler waters and thus in better condition when the winter swells hit, and a much greater percent survived. Otters make kelp forests healthy Professors Chris Wilmers and James Estes, University of California Santa Cruz, have combined 40 years of data on otters and kelp bloom from Alaska’s Aleutian Islands and along the Pacific coast to Vancouver Island. The forests are extremely delicate ecosystems, with sea otters being the keystone predators (a predator that maintains balance by preying on a herbivore which would otherwise eliminate an important plant species) in the Alaskan region. NOAA Live! History: The Giant Kelp forest is magnificent forest located in Alaska and along the west coast of North America. Large numbers of opaleye or halfmoon fishes can damage kelp forests, particularly when the kelp is exposed to unfavorable growing conditions. By about the mid 1990s, the population of otters were clearly in decline. Off the California coast, lies one of the fastest growing forests in the world. Welcome to: Kelp Forests of Alaska! Kelp are large brown algae that live in cool, relatively shallow waters close to the shore. Alaska’s experiment with kelp is nothing new: each year, hundreds of thousands of tonnes of seaweed are harvested around the world, with China and Japan leading global exports. Alaska events page and webinar recordings. Kelp and sea urchin abundance remained largely unchanged at most sites where sea otters were continuously present or absent, the one exception being at Torch Bay (southeast Alaska), where kelp abundance varied significantly through time and urchin abundance varied significantly among sites because of episodic and patchy disturbances. Kelp forests are habitat for many invertebrates that are food for over 20 species of fish; these forests also provide spawning habitat for herring and Atka mackerel as well as nursery areas for s Sea otters are keystone predators that maintain the dense, productive forests of kelp in coastal Alaska. Classic studies in kelp forest ecology have largely focused on trophic interactions (the relationships between organisms and their food webs), particularly the understanding and top-down trophic processes. Alaskan kelp forests are likely to have been well developed before human contact because sea otter predation on sea Table 4 Spatial and temporal scale of change among three kelp forest … Photo by David Duggins. 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. If this continues, the kelp forests could someday By about the mid 1990s, the population of otters were clearly in decline. Kelp forests in the eastern and northern Pacific commonly have complex three- dimensional structure, with many coexisting species. One such ecosystem that is endangered is the kelp forest on the coast of alaska. WHAT DOES KELP … Sea otters like to hang out in the kelp forest, where they find their favorite food and can wrap up in a kelp frond to keep from drifting away at naptime :) 7.) Without sea otters around to eat urchins, Alaska's kelp forests and algal reefs have been left vulnerable to overgrazing. Threat to UK's Kelp Forests. Many of these kelp forests support large sport and commercial fisheries as well as a vibrant recreational diving […] Along the Norwegian coast these forests cover 5800 km 2, and they support large numbers of animals. For example, the occurrence of kelp is frequently correlated with oceanographic u… http://upload.wikimedia.org/wikipedia/commons/5/5a/Kelp_forest_distribution_map.png. 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 … 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). and healthy before they became effected by humans and their actions. Tiered like a terrestrial rainforest with a canopy and several layers below, the kelp forests of the eastern Pacific coast are dominated by two canopy-forming, brown macroalgae species, giant kelp (Macrocystis pyrifera) and bull kelp (Nereocystis leutkeana). Create your own unique website with customizable templates. This can also happen with ecosystems. In Alaskan kelp reefs, otter populations help to keep sea urchin populations in check. Large numbers of opaleye or halfmoon fishes can damage kelp forests, particularly when the kelp is exposed to unfavorable growing conditions. These animals are capable of doing extreme damage to kelp forests in very small time frames. Alaska is home to three types of kelp: Macrocystis (two kinds, one of which is giant kelp), Nereocystis luetkeana (bull kelp) and Alaria fistulosa. They’ve already eaten through many Alaskan kelp forests, one of the world’s great carbon sinks. Kelp can grows faster than tropical bamboo. SAVE THE KELP! Kelp Forest Monitoring Internship Canopy-forming kelp beds serve an important role in coastal resilience by providing critical habitat for many marine species of both economic and conservation value. 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. Along the central California coast where the distribution of giant kelp and bull kelp overlap, giant kelp out competes bull kelp for light.Kelp survival is positively correlated with the strength of the substrate. Otters are crucial in keeping kelp forests healthy and thriving. If this continues, the kelp forests could someday “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. Kelp forests grow predominantly along the Eastern Pacific Coast, from Alaska and Canada to the waters of Baja, California. They also reduce coastal erosion by serving as a buffer against strong waves. It however runs down the entire pacific coast of canada and the United States. Kelp forests grow predominantly along the Eastern Pacific Coast, from Alaska and Canada to the waters of Baja, California. Kelp forests are among the most unique and ecologically diverse ecosystems in coastal temperate oceans and are found globally. Kelp forests grow along rocky shore lines, and mostly in the Pacific Ocean. 8.) All different types of fish which use the kelp forest as a safe place.
