The Arctic willow is a food source for several Arctic animals. Muskoxen, caribou, Arctic hares, and lemmings all feed on the bark and twigs, while the buds are the main food source of the rock ptarmigan. It is the primary host plant and food source for the Arctic woolly bear moth (Gynaephora groenlandica). [10]
One commonly known medicinal benefit from the willow tree is the use of its bark. Alaska Natives and other Native American tribes have used the bark from the Willow tree as a pain killer. In fact, the bark does contain acetylsalicylic acid which is now called aspirin and has been commercialized as an over the counter pain killer. [7]
The black willow is the only United States native willow species to be used as timber for a variety of different items. Black willow lumber is used in furniture and shipping containers. The largest production site for black willow timber was in Louisiana at its peak during the 1970s. [21] The wood of Salix nigra is very lightweight.
Willow roots spread widely and are very aggressive in seeking out moisture; for this reason, they can become problematic when planted in residential areas, where the roots are notorious for clogging French drains, drainage systems, weeping tiles, septic systems, storm drains, and sewer systems, particularly older, tile, concrete, or ceramic pipes.
Diamond willow is a type of tree with wood which is transformed into diamond-shaped segments that have alternating colors. Salix bebbiana , the most common, is a species of willow indigenous to Canada and the northern United States, from Alaska and Yukon south to California and Arizona and northeast to Newfoundland and New England.
The Arctic willow, commonly named rock willow, is found in the North American tundra. Most uniquely, the Arctic willow often has long trailing branches that root where they intersect with the surface of the ground, and the roots are shallow as to thrive in the frozen ground of the tundra (Wielgolaski 1972).
Research has linked B-vitamins (like B6, B12, and folate) to reducing risk of cognitive decline due to potential memory boosting benefits, says Jaclyn London, M.S., R.D., C.D.N. Citrus fruits
Arctic hares feed primarily on woody plants, with arctic willow constituting 95% of their diet year-round. [15] Arctic hares predominantly consume saxifrage, crowberry, and dwarf willow, but can also eat a variety of other foods, including lichens and mosses, blooms, other species' leaves, twigs, and roots, mountain sorrel and macroalgae (seaweed).
