Osier bed

An Osier bed is where historically willows were planted and coppiced to produce withies, which were used for basket making, fish-traps, and other purposes. The willow species "salix viminalis", known as the "common osier" was typically, although not exclusively grown for this purpose. The marshy fringes of rivers, especially those which are often overwhelmed regularly by tides and those with small islands, aits, eyots, or holts, were are the most common locations for osier beds. Willow rods (cuttings) would be planted, which root easily in moist ground, and the growth of the willow withies would be cut every one or two years.
Osier beds and basket-weaving using willow were a significant industry in Great Britain until the early 20th Century, when industrial machinery and the import of cheaper materials made them unprofitable and commercially unviable.
