In the Puget Sound region, bull kelp (Nereocystis luetkeana) occurs throughout Puget Sound and the Strait of Juan de Fuca, while the distribution of giant kelp (Macrocystis integrifolia) is restricted to the Strait of Fuca (Berry et al. Excess nutrients in agricultural and urban runoff could be enabling other species like turf-forming algae to outcompete kelp. bull kelp. Another vital forest at risk: Scientists fear warming water could be killing off Puget Sound’s kelp beds Sep. 12, 2019 at 6:09 pm Updated Sep. 15, 2019 at 9:54 am Back to story Restart gallery “This is a vital spot for all kinds of animals in our region.”. The most common kind, and the largest, in Puget Sound is Bull Kelp. At first, the decline of kelp in Puget Sound seemed unlikely. The map is also emblematic of a variety of recent studies, using diverse methods, that have documented kelp decline and disappearance in many parts of Puget Sound. What they are finding is bringing kelp to the forefront of Puget Sound's environmental concerns. Jellyfish aggregations are visible in Budd and Sinclair Inlets — and some of the jellyfish might conceal a beast of another kind within. Kelp beds look strong in northern Puget Sound and the Straits; and the harvest of the annual chum salmon run is in full swing in Hood Canal. . She comes back to visit her home village once a year, but as the years go by, the woman becomes more and more a being of the sea. A pilot planting of bull kelp in Washington state’s Puget Sound. But at the same time, the edges of kelp beds are often prime fishing spots. Protecting and restoring kelp species in Puget Sound contributes to … B.2.2 The Kelp Highway Archaeological evidence suggests that the Americas may have first been settled by maritime peoples following the rich assemblage of marine resources found in the kelp forests that extend Farther South in Puget Sound, kelp is in even worse shape, as state DNR researchers have established. Now, increasing average water temperatures, stronger El Niños, and marine heat waves such as “the Blob” may be pushing kelp into the danger zone more often – a problem that is only likely to get worse as climate change intensifies. Kelp is found almost anywhere where there is hard sub- strate in shallow water, including pilings and other artificial surfaces. “Luckily, we still have areas where [bull kelp] occurs” in Puget Sound, says Helen Berry, manager of the Nearshore Habitat Program at the Washington Department of Natural Resources. Kelp is a vital habitat for rockfish and numerous additional species including forage fish, … These are the southernmost of the roughly 25 to 30 beds being tracked in the program. They shed the spores in summer and fall, and these grow into the tiny, filamentous gametophytes, the sexual generation. along the fringes of Puget Sound, Eelgrass blades (up to 3 feet long) ripple in the current and provide a place where salmon, other fish, and shellfish feed and hide. Photo: Cody Logan (CC BY-NC-SA 2.0). For a few weeks in the summer of 2019, full-grown bull kelp plants waved languidly at the surface of the water in Smith Cove near Seattle. Anglers wondered where bull kelp beds had gone. “Kelp is awesome for the same reasons that coral reefs and eelgrass and mangrove forests are awesome,” says Max Calloway, a biologist working on kelp projects with the nonprofit Puget Sound Restoration Fund (PSRF). other indicators of habitat health along Puget Sound’s shorelines. We envision revitalized Puget Sound kelp forests stretching from Olympia to Vancouver, B.C. About the author: Sarah DeWeerdt is a Seattle-based freelance science writer specializing in biology, medicine, and the environment. Bull kelp (Nereocystis luetkeana) is one of 23 species of kelp found in Puget Sound. For about eight years, Allen has been keeping an eye on a kelp bed just outside Bainbridge Isl… They rival tropical forests in their richness and diversity, but Puget Sound's kelp beds have declined steeply in recent decades. Between 2013 and 2018, researchers at the Washington Department of Natural Resources studied four bull kelp … And seaweeds are themselves under threat. It was hard to go to a beach in Puget Sound and not find long strands of bull kelp … purple laver. McLeod’s father has been fishing commercially for salmon, crab, shrimp, and dogfish since the late 1950s. Located on the protected harbors of Puget Sound, this charming city is the gateway to the Olympic Peninsula, with a majestic backdrop of mountains, glaciers, forests, lakes, and sea. McLeod, a Samish tribal member and field technician with the tribe’s Department of Natural Resources, wanted his father’s help mapping the historic location of bull kelp beds around the islands. The Samish and other Coast Salish tribes have a story about a woman who marries a man from beneath the sea. Bull Kelp is easily recognized by its very long stipe (stalk), up to 30 meters or more in length, extending from the holdfast that attaches it to the bottom to a floating hollow bulb that may be over 10 centimeters in diameter. “The solution is not going to be a Washington solution,” he says, “it’s going to be a global solution.”Various agencies, tribes, and nonprofit groups are strategizing about how to investigate these hypotheses. Bull kelp (Nereocystis luetkeana) is the primary canopy-forming kelp species found throughout Puget Sound. “The farther you get away from the open ocean – closer to human impacts and farther away from oceanic water – those are the areas where we’re most concerned about kelp losses,” Berry says. Kelp refers to large brown seaweeds in the order Laminariales. In response to these widespread concerns, the Puget Sound Kelp Conservation and Recovery Plan provides a research and management framework for a coordinated and collaborative approach to protecting and restoring kelp forests of Puget Sound. The total extent of the loss has not been estimated, because most of the lost patches were never measured for size. The large plants are sporophytes and produce spores along the blades in sori comparable to fern sori. For example, the Samish DNR will use an ROV to gather clues about stressors that might be affecting local kelp beds next summer. Individual county Marine Resources Committees then recruited citizen-scientist volunteers to survey a handful of kelp beds in each jurisdiction. Not the least of which is us. providing “We think that loss has been going on for quite a bit longer” than a decade, says Samish DNR head Todd Woodard. Kelp beds are formed by mature sporophytes. As Puget Sound temperatures increase, bull kelp struggles to stay alive. Scientists noticed kelp beds they’d long known as reliable landmarks shrinking or disappearing altogether. The hollow upper part of the stalk is also filled with gas (including carbon monoxide! 2019 Monitoring Story Map Then the purple urchins took over, eating and eating until the bull kelp forests were gone. Competition with the invasive alga Sargassum muticum may also be a factor. The array of species found in Puget Sound reflects its high productivity, the wide diversity of habitats present, and its unique geographic location at the interface of “northern” and “southern” ranges for many species. These blades provide the plant with both photosynthesis and nutrient absorption. NOAA supports a number of monitoring, research, and conservation initiatives to support kelp conservation. Kelp freely shares the energy it captures through photosynthesis, constantly releasing dissolved sugar and sloughing bits of tissue into the water, providing a foundation for the food web near the shoreline. Specifically, they were working with bull kelp (Nereocystis luetkeana), a fast growing annual that is a dominant plant in the region's kelp forests. Kelp also forms a significant portion of the diets of the small fish and invertebrates that juvenile salmon prey on. The Maiden of Deception Pass carved by Tracy Powell tells the story of Qw'elqw'o7lewut [pronounced phonetically as Ko-Kwal-alwoot], a Samish woman who goes to live underwater to save her people from starvation. Dense stands of canopy-forming kelp are known as kelp beds or, if they are particularly large, kelp forests. Larger kelp species are struggling in Puget Sound, where water temperatures are increasing at a substantial rate, especially in the South Sound. Kelp and eelgrass are broadly distributed in Puget Sound. This signature, leafy algae was thought to be especially hearty and resistant to some of the stressors that have affected other shoreline species like eelgrass. Kelps are cold-water organisms, and bull kelp does best in water between about 5 and 17 °C. giant kelp. “If that is the problem, it’s going to be a hard one to fix at a local level,” says Tom Mumford, a retired state DNR kelp biologist. These gametophytes shed sperm and eggs in winter and early spring, and when fertilized, the eggs develop into the familiar sporophytes. Kelp forests of Puget Sound are ecosystem foundations, like coral reefs and tropical rainforests, which supports diverse and productive communities. The next question is whether restoration efforts can produce a kelp bed that comes back for a second year. Photo courtesy of the Puget Sound Restoration Fund Once winter is over, the kelp … They provide critical refuge, feeding, and nurserygrounds for forage fish, rockfish, and salmon, as well as fueling food webs that support healthy bird and marine mammal populations—including Southern Resident killer whales. Both form conspicuous floating canopies, or kelp beds. “Since 2013 the major stressor on kelp has been water temperature. McLeod listened as they debated back and forth and drew on the map areas of agreement. The result was a portrait of kelp both familiar – such as the beds that fringe the western side of San Juan Island – and vanished: The men remembered a kelp forest filling a portion of Bellingham Channel, for example, that there’s no trace of today. “You look down and a Chinook salmon swims by, there's forage fish in hiding among the leaves of the kelp,” says Alan Clark, a Sequim resident who is part of a citizen-science project to monitor kelp beds in the Strait of Juan de Fuca by kayak. Kelp forests can rival tropical rainforests in primary productivity, meaning the amount of the sun’s energy transformed into living organisms in a given amount of time. Snohomish County has emerged as an area of particular concern, Oster adds. The chart depicted the traditional territory of the Samish people in the San Juan Islands. The map of tribal elder knowledge that McLeod worked on adds another dimension to the findings. Natural kelp forests in Puget Sound are dying from rising ocean temperatures and oxygen depletion. It’s a local story with links to global concerns, as kelp habitats off the coasts of California, Australia, and Tasmania have all experienced severe declines in recent years. Kelp overwinters as either gametophytes, which are microscopic and may be able to persist in the environment for multiple years, tiny sporophytes, or a mix of both. Another vital forest at risk: Scientists fear warming water could be killing off Puget Sound's kelp beds. One reason may be that kelp is harder to study. In summer 2019, the program was active in six counties – Clallam, Island, Jefferson, Skagit, Snohomish, and Whatcom. The most common kind, and the largest, in Puget Sound is Bull Kelp. of kelp to Puget Sound’s nearshore food webs, these declines may be cause for alarm. eel grass. They are the forests of the nearshore waters. Because the holdfast grows anew each season, it is not as large or tenacious as the holdfasts of perennial kelps, and in rough weather, entire plants may be pulled loose. But as the researchers looked closer, a more alarming picture emerged. The magnificent sunflower sea stars, pushed to the edge of extinction by sea star wasting disease, have been declared a “critically endangered species” by the International Union for Conservation of Nature. Months earlier, PSRF divers had attached lengths of twine, coated with a brown fuzz formed by millions of millimeter-long young kelp plants, to concrete anchors they had placed on the sea floor. Their fishery closed. That life cycle includes two distinct phases, known as the gametophyte and the sporophyte.
