Approximate area covered by potential for kelps (Burrows et al., 2014) is provided in the table in brackets. Share 3.14.2. Little information is available about the extent or volumes of such gathering. Beach-cast seaweeds (mainly kelps) and (potentially) seagrasses may occur on the shoreline in drift lines, as a result of wave action during storms. Scotland has great water quality and there are lots of controls for this., However, Peter goes further: Scotland on a whole is in a very good position, but it still needs to be managed on a local level. Key objectives relate to coastal and offshore designated and undesignated buildings, archaeology and wrecks. The only strandline habitat that has been recorded is in outer Tay Estuary and north coast of Orkney. Thongweed is edible. The company gets its name from the boys' coastal hometown, where the seaweed is hand-picked, washed, packaged and promoted. Laminaria is the main seaweed used in Scotland, but Red-weed, green-weed, purple-weed, and pinkweed each with its own unique benefits. In the north region, there are widespread records of maerl beds in tide-swept areas, especially in Orkney and Shetland and Loch Eriboll on the north coast of the Scottish mainland. Like plants, marine algae use chlorophyll for photosynthesis. No gardener can match the perfection of beauty found in a rock pool. It is picked by hand at low water. Often these dominant species appear to be stable features of the shore. 3.14.1. Opportunists are normal members of all communities. It is therefore crucial that when we use our seas as a means of food production that we do so sustainably with as little impact as possible. The growth of seaweeds and seagrasses, their distribution, and ultimately their effectiveness in providing ecological functions and ecosystem services is a result of several climatic and environmental factors which can vary both spatially and temporally. In Scotland, some beach-cast, Common name/s: Carragheens, Irish moss or Carrageen moss, Common name/s: Carragheens, Climhin Cait, False Irish moss, Harvested at low tide by hand with scissors or a blade above the holdfast to allow regrowth. A lease tends to be for a three year period at the end of which a report must be submitted to inform a review of the sustainability of the harvesting practice, approval of which will allow the lease to be renewed. Exposed at low tide. However, the groups also differ in more complex structural and biochemical features, such as their photosynthetic pigments and cell structure. Squeeze as you go between each roll to make sure the roll sticks together. Edible; used as a thickening agent. Table 4: Target seaweed and seagrass species for harvesting. These have been used as the assessment areas for hazardous substances. Juvenile plants are avoided. A summary of known seaweed harvesting is provided in Figure 8 and Table 6 including the general location, methods and (where known/appropriate) season of harvesting. Hand and mechanical using modified boat with cutter. To avoid a mess, cover your bamboo mat in plastic wrap and lay a piece of nori paper on top, shiny side down.

Indicator species can mark a change in the condition of an ecosystem. types of seaweed in scotland - loriandlisasell.com Currently, with seaweed harvesting and cultivation mostly occurring as small scale activities in Scotland, no information is available on its economic contribution. Plants are cut above the meristem (growth point) to allow regrowth, Hand harvested by wading, diving or cutting from a small boat at low tide using knives, scissors or scythes. The main interest is in: 3.11.2. Our seas produce some of the finest seafood in the world and our coast is prime territory for enjoying seaweed foraging in Scotland. For example, there is known to be an abundance of Ulva sp. Wracks primarily grow on intertidal rocky shores and also on sheltered, mud, sand or gravel shores. Figure 1: Seaweed resource areas from 2016 Strategic Environmental Assessment (SEA) of wild seaweed harvesting. These cover methods used in Scotland and in other countries. The main seaweed species being grown in the trials is edible kelp (Zero Waste Scotland, 2019). Published eight times a year, British Wildlife bridges the gap between popular writing and This small, red seaweed was first recorded in South West England in 1890 having been introduced from Japan. Grows on rocks in mid-zone of shores. This method involves the collection of beach-cast species from the strandline using tractors or JCBs. Few or no concerns, but some local concerns, Few or no concerns, but many local concerns, Lack of evidence / robust assessment criteria. Distribution: Found on the lower shore and in deep rock pools. An almost identical species, Pyropia yezoensis, is cultivated in the Far East in the millions of tons. Wild seaweed harvesting: strategic environmental assessment Often they are grouped into red, brown or green species, but these are not rigid distinctions. There are over 650 species of seaweed found around the UK and were on the lookout for 14 of them. 3.11.4. Mechanical cutting of egg or knotted wrack takes place in Lewis and Harris. However, there can be an exceptional abundance of them when there is physical disturbance or considerable nutrient enrichment. Again, it is not possible to show a numerical depth limit in the sublittoral as this depends on water clarity and varies geographically. A monster of a seaweed, its our largest at up to four yards in length. Foraging sea greens is great fun, but watch the tides and take care to collect them away from any potential sources of pollution. Found in upper zone of rocky shores. Nori Lyudmila Zavyalova/Shutterstock We'll start off with an easy one. Review of Scottish seaweed harvesting rules. Operations involving the harvesting of living or beach-cast seaweed in the wild, with some exceptions, require the permission of the relevant landowner. Peters tells me that, This stamp is really important to us because of the levels we go to to be sustainable., In 2015 SHORE started an Environmental Impact Assessment which Peter explains: We have four locations on our sites around Caithness where we carry out research on the community of plants and animals on the shore around the seaweed. General guidance on Marine Licensing can be found online at: http://www.gov.scot/Topics/marine/Licensing. Outer Hebrides; Orkney; Caithness (Ham to Scarfskerry). Other smaller beds are found along the West coast of Scotland, such as in Loch Ryan, Loch Sunart, in the Montrose Basin and in the Forth and Tay Estuaries ( JNCC, 1995; SNH, undated). 3.16.1. This is a brown seaweed, but can sometimes be yellow or green in colour. "There is current interest and there may be more interest in future in new types of seaweed harvesting in Scottish water. These vessels include the Norwegian suction/cutter harvester which is designed to harvest Ascophyllum nodosum. Harvesting is done by hand cutting or raking, usually in late summer. There is growing commercial interest in Scotland in the seaweed resource as properties of various species and potential uses in various products are being recognised.

Similarly, as most species require a firm substrate to anchor to, rocky shores will be home to more seaweeds than sandy or muddy ones. Intertidal. They are widely distributed in colder zones and are absent from tropical waters. Commercial wild seaweed harvesting is having a revival in Scotland. The two dominant groups of large seaweeds on the shore, wracks and kelps, generally have different habitat preferences. The Millenium Ecosystem Assessment recognised four types of services: provisioning; regulating; supporting; and cultural ( MEA, 2005). In Scotland seagrasses grow in sheltered waters such as inlets, bays, estuaries and saltwater lagoons; in more exposed areas beds tend to be smaller and patchier (Davison & Hughes, 1998). In the west region maerl is found within sea lochs and inlets on the mainland such as the Sound of Arisaig and Loch Laxford and areas such as Loch nam Madadh and the Sound of Barra in the Outer Hebrides. ID notes: Dark reddish-purple branching seaweed which appears iridescent when submerged. Tens of thousands of people from Orkney, the West Coast and . Alterations to temperature, pH and sea levels along with several other factors may result in community shifts which have the potential to affect the ecological functions and ecosystem services currently provided by seaweeds (Jackson et al., 2012). This small, red species has tiny harpoon-shaped structures along each branch. Officinalis, incidentally, is found in the Latin names of species used by apothecaries. 3.8.3. Also known as native oysters, these incredible bivalves live on the seabed in shallow coastal estuaries. There is a lot of noise about how wonderful seaweed is but it is quite an alien and forgotten food. This method involves harvesting living species by hand at low tide using tools such as serrated sickles or scythes. A kelp characteristic of strong wave action, Alaria esculenta, occurs around the low water mark and in the shallow sublittoral. These can be abiotic (physical or chemical features) or biotic factors, such as biological competition. 3.8. To view full details of the literature source, click the title. Globally, there are approximately 7000 red, 2000 brown, and 1700 green species of seaweed. These area estimates do not account for the quality of the resource (in terms of biomass and density) and whether it is suitable for harvesting. To find out more about SHORE, visit their website here. Conversely, seagrasses are predicted to proliferate if they are adequately protected from other anthropogenic pressures (Brodie et al., 2014). 3.14.6. | Website by Yellow Cherry, Scottish Seaweed: A Sustainable Superfood, Highland Good Food Partnership is a Scottish Charitable Incorporated Organisation, registered no. Blades are cut from existing plants, leaving the stipe and lower blade intact and able to keep growing. Figure 2: Seaweed harvesting by hand. You can change your cookie settings at any time. Where there's less wave action, it often forms dense, branched, spiny nodules up to 10cm in diameter. Only two harvesters were able to respond to queries within the timescale of this SEA and therefore this information is not comprehensive. British Wildlife is the leading natural history magazine in the UK, providing essential reading 3.10.1. Despite being a foreign introduction, its never caused any problems, just the little buzz of joy in seeing something so peculiar bobbing about in the sea. Figure 2: Available spatial information on the distribution of kelps, maerl, wracks and green seaweeds, Figure 3: Available spatial information on the distribution of potential areas for kelps, and the distribution of red seaweeds, seagrasses and beach-cast seaweeds or seagrasses. Indeed, one of them is now our production coordinator and he knows everything there is to know about everything! He continues, As we are driven by the tides, harvesting is not a full-time job but by bringing more activity into Wick, which we have started this year, we can offer more stable employment for people as well., Peter adds: When we started, no one had a clue about seaweed. Harvesting takes place all year. Distribution: Found on the mid-shore on sheltered rocky coasts. This will allow for the best targeted Environmental Assessment to be undertaken, reducing both likelihood of unnecessary assessments being conducted by the applicant and the risk of future challenge to licensing decisions. 3.10.2. It is also considering the environmental implications of seaweed removal by any method. When mature, fronds have yellowish, paired swollen tips; these are the reproductive structures. However, projections estimate this figure could increase substantially by 2040. Broadly speaking, species fall into the group that most closely matches their colour. MaraSeaweed, Angus Bremmer. 21 November 2018. . Opportunists are generally smaller, have simple form, short life-span, fast growth rate, a relatively wide tolerance to environmental conditions, and are reproductive for most or all of the year so that they can rapidly and opportunistically colonise spaces that occur in habitats. This brown seaweed has paired air bladders (which look like bubbles). In the case of kelps, this involves a device which tears living plants larger than a certain size from the substrate and leaves smaller plants for re-growth ( i.e. Spread a thin layer of rice over the nori sheet. This method involves the collection of beach-cast species from the strandline by hand. 3.6.1. 3.15.5. Edible; used as a sugar substitute. SHORE are licensed to pick wild seaweed on their sites and they stick to a quota which means they can only harvest 20% of the biomass of each of the 17 species of seaweed they use each year. 3.1.3. The chemical common to both is dimethyl sulphide. Community growing coordinator. The ecosystem services that have been scoped into this SEA are described in more detail in the relevant sections of this Environmental Report. Removal using a vessel for operational reasons, Firth of Lorn; Argyll islands including Luing and the Garvellachs, Unspecified small amount (range: tens of kilos), Up to 11,500 wet tonnes per annum on CES foreshore, Additional tonnage on private, community land unknown. Pebble and gravel shores that can support large seaweeds will be very sheltered and so will have wracks and kelps characteristic of strong shelter. Key deliverables are expected to cover: An OSPAR agreed list of marine pressures is used to help assessments of human activities in the marine environment. An example is the replacement of Laminaria communities in Nova Scotia by sea urchins after excessive kelp removal by harvesting (see Section 6.2 ). Maerl is found along the west coast of Scotland, in the Western Isles, Orkney, Shetland and the north coast, but is absent from the east coast (Figure 2). Although this species is also known as sea spaghetti, I prefer thongweed because it brings those sea nymphs to mind. A Scottish Government review is underway to gather evidence on the environmental implications of seaweed removal by any method and to consider the sustainable development of the seaweed sector. This species is soft to touch and has large, obvious curved hooks. They would still require a lease from The Crown Estate.

The extent and impact of the pressure will also vary depending on the sensitivity of the habitat or species on which it is acting. This vessel works close to the shore and cuts the seaweed as the stalks float above the seabed. The total volume of seaweed harvested is recorded to be around 15,000 tonnes. In terms of biomass, the majority of Ascophyllum nodosum around the Outer Hebrides is primarily located around Lewis, North Uist and South Uist and Harris (Burrows et al., 2010). A2.61 Seagrass beds on littoral sediments. Many environmental factors affect the distribution of seaweed and seagrasses.
