Why is kelp so important?
Kelps as important biodiversity and feeding grounds The forests created by kelps provide a home for a huge variety of different species, from other benthic algae to invertebrates, fish and marine mammals.
Why is kelp good for the environment?
Kelp, in particular, has the potential to greatly reduce ocean acidification. Naturally occurring in cold, coastal marine waters, kelp grows quickly without the need for fertilizer, and it takes up carbon dioxide—which can exacerbate climate change—as well as excess nitrogen and phosphorus.
What are kelp forests and why are they important?
Kelp forests are the anchor of nearshore ocean wildlife communities across the U.S. West Coast and northeast, sustaining marine biodiversity by providing shelter, habitat and even food for an array of fish and invertebrates.
Are kelp forests good for the environment?

Why are kelp forests important?
Kelp forests are key assets in the effort to control the effects of climate change and are likewise quite susceptible to these effects if not given a helping hand. © Fletcher Forbes. Preserving and sustaining a biologically rich ecosystem is a significant way kelp forests can help stem the tide of climate change effects.
How does kelp forest help the ocean?
Kelp forests are the anchor of nearshore ocean wildlife communities across the U.S. West Coast and northeast, sustaining marine biodiversity by providing shelter, habitat and even food for an array of fish and invertebrates. The many varieties of kelp—a marine algae rather than a true plant—expand the habitat available for kelp forest residents by reaching upwards from the seafloor. Kelp species range from low-lying “bottom kelp” types or much taller species like California’s giant kelp, which can reach the surface from 80-foot depths or more. This third dimension helps make kelp forests among the richest habitats on Earth.
What is the role of kelp forests in the ocean?
What’s less known are the risks kelp forests face from a changing ocean and the role they play as a bulwark against a host of ocean problems, including climate change.
What is kelp forest?
Kelp forests are the anchor of nearshore ocean wildlife communities across the U.S. West Coast and northeast, sustaining marine biodiversity by providing shelter, habitat and even food for an array of fish and invertebrates.
Why are kelp forests important?
Because of this, kelp forests are critical for fishing and recreation industries. Unfortunately, overfishing disrupts the balance of kelp forests by removing predators and allowing plant-eating populations to explode and overeat the kelp, destroying the forests.

Pollution, such as sediment runoff and industrial waste, also contributes to the destruction of kelp forests. Today, many kelp forests are located in marine protected areas and are studied by NOAA scientists.
How many tons of kelp are harvested in California?
Between 100,000 and 170,000 wet tons of kelp are harvested from California waters each year. Kelp forests are extremely biologically productive habitats for a huge range of sea creatures including fish, urchins, sea otters, sea lions, and even some whales.
What is kelp forest?
Kelp forest. Kelp forests are under water areas with a high density of kelp, which covers a large part of the world's coastlines. They are recognized as one of the most productive and dynamic ecosystems on Earth. Smaller areas of anchored kelp are called kelp beds.
What are the factors that make kelp survive?
The environmental factors necessary for kelp to survive include hard substrate (usually rock or sand), high nutrients (e.g., nitrogen, phosphorus), and light ( minimum annual irradiance dose > 50 E m −2 ).
What are the trophic interactions in kelp forests?
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. Bottom-up processes are generally driven by the abiotic conditions required for primary producers to grow, such as availability of light and nutrients, and the subsequent transfer of energy to consumers at higher trophic levels. For example, the occurrence of kelp is frequently correlated with oceanographic upwelling zones, which provide unusually high concentrations of nutrients to the local environment. This allows kelp to grow and subsequently support herbivores, which in turn support consumers at higher trophic levels. By contrast, in top-down processes, predators limit the biomass of species at lower trophic levels through consumption. In the absence of predation, these lower-level species flourish because resources that support their energetic requirements are not limiting. In a well-studied example from Alaskan kelp forests, sea otters ( Enhydra lutris) control populations of herbivorous sea urchins through predation. When sea otters are removed from the ecosystem (for example, by human exploitation), urchin populations are released from predatory control and grow dramatically. This leads to increased herbivore pressure on local kelp stands. Deterioration of the kelp itself results in the loss of physical ecosystem structure and subsequently, the loss of other species associated with this habitat. In Alaskan kelp forest ecosystems, sea otters are the keystone species that mediates this trophic cascade. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead. The effect of removing one predatory species in this system differs from Alaska because redundancy exists in the trophic levels and other predatory species can continue to regulate urchins. However, the removal of multiple predators can effectively release urchins from predator pressure and allow the system to follow trajectories towards kelp forest degradation. Similar examples exist in Nova Scotia, South Africa, Australia and Chile. The relative importance of top-down versus bottom-up control in kelp forest ecosystems and the strengths of trophic interactions continue to be the subject of considerable scientific investigation.
What is kelp algae?
The term kelp refers to marine algae belonging to the order Laminariales (phylum: Heterokontophyta ). Though not considered a taxonomically diverse order, kelps are highly diverse structurally and functionally. The most widely recognized species are the giant kelps ( Macrocystis spp.), although numerous other genera such as Laminaria, Ecklonia, Lessonia, Alaria, and Eisenia are described.
What is the understory of kelp?
Multiple kelp species often co-exist within a forest; the term understory canopy refers to the stipitate and prostrate kelps. For example, a Macrocystis canopy may extend many meters above the seafloor towards the ocean surface, while an understory of the kelps Eisenia and Pterygophora reaches upward only a few meters.
How does kelp work?
Giant kelp uses gas-filled floats to keep the plant suspended, allowing the kelp blades near the ocean surface to capture light for photosynthesis. The architecture of a kelp forest ecosystem is based on its physical structure, which influences the associated species that define its community structure.
How does water flow affect kelp?
Water flow and turbulence facilitate nutrient assimilation across kelp fronds throughout the water column. Water clarity affects the depth to which sufficient light can be transmitted. In ideal conditions, giant kelp ( Macrocystis spp.) can grow as much as 30–60 cm vertically per day.
Why is kelp important to the ocean?
Kelp is also farmed as a crop, part of a $5 billion global seaweed-farming industry. Kelp absorbs CO2 from seawater, helping fight climate change while also making nearby water less acidic. That's why many kelp farms also raise shellfish, since less acidity creates a better environment for shell growth.
Where are kelp forests found?
Kelp forests are found throughout the world including along the west coasts of North and South America, the southern tip of Africa and Australia, and islands near Antarctica. In North America, kelp forests are found on the Pacific Coast, from Alaska and Canada to the waters of Baja California, reports NOAA.
What are the underwater kelp forests called?
Insects. Towers of underwater kelp form undulating forests in shallow waters in many parts of the world. Sometimes called the rain forests of the sea, these lush beds of seaweed are also disappearing like the jungle forests.
Where does kelp get its algin from?
It's even used in some pharmaceuticals. Algin is extracted from kelp and used as an emulsifying agent in these products. Between 100,000 and 170,000 wet tons of kelp are harvested just from California waters each year, according to NOAA.
