The many browns, greens and reds of the seaweeds are naturally arranged for greatest artistic effect and currents and small waves dramatically change the view every few seconds as the fronds slip over one another and the light changes. When it gets to a certain size, its oxygen-filled body is sufficiently buoyant to lift the unfortunate oyster from the seabed and float off with it. How to forage for seaweed | Foraging | The Guardian These efforts also ensure that the wildlife at the sites around Caithness is not disturbed by having all SHORE harvesters trained in the Marine Wildlife Conduct Code. Figure 11: Legislation and Policy Context for Wild Seaweed Harvesting. However, there can be an exceptional abundance of them when there is physical disturbance or considerable nutrient enrichment. There are not currently sufficient seaweed harvesting activity data to make trends relevant. In some areas, harvest is during a narrow window in early summer, after plants have put on reasonable growth but before breaking waves shred the thin leaves. (Angus, 2012). The wracks are almost entirely intertidal, while the kelps dominate the subtidal, forming the kelp forest, but also extend into the lowest intertidal just above the low water mark.

Figure 2: Seaweed harvesting by hand. Below the low water mark, increasing depth results in a very rapid decrease in light intensity so that sublittoral (subtidal) species are restricted to a depth range near the surface, known as the photic zone, where light is sufficient for growth. 3.5.1. Lots of ocean species, like seaweeds, struggle to grow in these conditions. Sheltered shores tend to provide a better location for many species, as most cannot survive the battering of the waves in more exposed locations. Figure c: Kelp forest in shallow water, Loch Laxford NatureScot. The trial also includes growing sea urchins on some of the seaweed. However, the groups also differ in more complex structural and biochemical features, such as their photosynthetic pigments and cell structure. Beach-cast seaweeds (mainly kelps) and (potentially) seagrasses may occur on the shoreline in drift lines, as a result of wave action during storms. The Scottish Government's vision is for 'clean, healthy, safe, productive, biologically diverse marine and coastal environments, which are managed to meet the long-term needs of people and nature'.

Seagrass has been used in the past, for example, as a material to thatch roofs, to stuff mattresses and for bandages (Reynolds, no date). Hand harvesting generally takes longer to regenerate requiring a longer period before returning to harvest the same area again, Typically harvested by hand at low tide with knives, scissors or scythes, cutting above the holdfast to allow regrowth, Typically hand harvested at low tide with knives, scissors or scythes, cutting above the holdfast to allow regrowth, Common name/s: Saw wrack or Toothed wrack, Gathered by hand during May and June, and the fronds are cut at least 10 cm from the mushroom-like base, Hand harvested by wading, diving or cutting from a small boat at low tide using knives, scissors or scythes.
