If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from.

Lead
Alaria marginata, the winged kelp, is a brown alga species in the genus Alaria. It can grow up to 13 feet. Fronds are long and narrow with raised midrib and wavy edges. Each frond has two rows of several smooth, oblong, 5 inch spore-bearing blades at the base in winter.
According to a study done by Widdowson(1971), the kelp Alaria marginata has been known to occupy certain wave-exposed intertidal habitats. These habitats can be found in the northeast Pacific from Alaska to near Point Conception, California. Alaria marginata has been the dominant macroalga on this exposed mid-to-low rocky shores along the Big Sur coast of California. The kelp commonly grows in large patches, which offers habitat and sustenance for tide pool organisms.

Seasonal changes
According to a study done by McConnico and Foster in the Science Direct, thinning of the kelp patches was inversely related to density. During the growing season from February to July, the kelp would grow in length up to 1.4 meters a month to form thick canopies.[2] The sorus development was found to be positively related to size and begins as early as March (peaking in late August-October). Releasing of the spores would take place most frequently between October and January, being associated with high water movement.[2]
Harvesting and uses
Alaria marginata are an edible kelp, commonly harvested in the spring and early summer to avoid frond harm from the summer storms. The upper frond and midrib can be harvested, leaving the lower portion of the frond to continue to grow.[3]
Once harvested, the alaria marginata can be used fresh or dried. To dry, fronds are hung off clotheslines for an even preservation. The midrib of the alaria can be cut out, separating the two opposing sheets and the stiffer midrib. Dried fronds can be stored in strips or pieces in a cool, dry place. [3]
