"Sea buckthorn (Hippophae rhamnoides) is another shrub that occurs in our region, and has shown invasive properties in other areas of Canada as well as the U.S. Sea buckthorn is a deciduous winter-hardy shrub that reaches 2 to 5 metres (6.5 – 16.4 feet) in height. The sea buckthorn’s leaves are alternate and narrow [and] are silver-grey colored. The small, yellow flowers appear in spring before leaves. Small, yellow to orange berries remain on the shrub throughout the winter.
In 2005, sea buckthorn was as ranked as the fifteenth most invasive plant of natural habitats in Canada following presentations at the 2004 Canadian Botanical Association's second symposium on invasive alien plants in Canada. This plant has recently attracted interest worldwide for its economic value as a nutritious food, a medicine, a soil enhancer, a pollution reducer, a source of firewood, and as a landscape management tool. It has been widely planted on the Canadian prairies to improve soil through nitrogen-fixing capability, to prevent erosion in dry and especially saline areas and for use as a shelterbelt. More recently it has attracted attention in Canada as an alternative crop, the leaves and berries being processed into a range of health foods and herbal products. Oil from the plant is also used for medicinal and cosmetic purposes."
