Poplars, Populus trees, provide the foundations for a range of forests around the Northern Hemisphere. They are the most abundant and extensive trees in Canada, and southern Alberta provides a global centre of poplar biodiversity as five species overlap and the four cottonwoods, or river valley poplars, hybridize. Cottonwoods also provide the parental species for artificial hybrid poplars, the fastest-growing trees in Canada and other temperate regions. Unfortunately, riparian cottonwood forests have been collapsing, largely due to river damming and water withdrawal for irrigation and other human uses.

杨树，白杨树，为北方的一系列森林提供了基础。 它们是加拿大最丰富、最广泛的树木，阿尔伯塔南部提供了全球白杨生物多样性中心，因为五个物种重叠，四种三角叶杨或河谷杨树杂交。 美洲黑杨还为人工杂交杨树提供了亲本物种，这是加拿大和其他温带地区生长最快的树木。 不幸的是，河岸的棉白杨森林正在崩溃，这主要是由于河流筑坝和取水用于灌溉和其他人类用途。
