Common Buckthorn is native to Europe and is also known as European Buckthorn. In Canada, it is found from Nova Scotia to Saskatchewan. It was likely introduced around the 1880s, becoming widespread in the early 1900s. This species was often used in hedgerows and windbreaks, and was widely planted across the country. Common Buckthorn is of concern to the agricultural community because it can host oat crown rust and soybean aphid, both of which reduce crop yields.
