Which plant-life zones extend from northern to southern Saskatchewan?

Saskatchewan features six distinct bands of natural plant life that extend from the north to the south of the province, generally following a northwest-southeasterly direction. These zones are as follows:1

• Subarctic woodland: Located in the northeastern corner, this area consists of widely spaced black spruce and jack pine with lichen ground cover.1
• Northern boreal forest: Situated southwest of the subarctic woodland, this zone is characterized by more densely packed black spruce and jack pine.1
• Southern boreal forest: A mixed forest belt south of the shield margin that includes broad-leaved trees such as trembling aspen.1
• Aspen parkland: This zone serves as a transition between the forest and grassland belts and is the most densely settled rural area in the province.1
• Mixed prairie: One of the two most southerly vegetation bands, dominated by mid-height and short grasses.1
• Dry mixed prairie: The southernmost band, where the abundance of short grasses increases as soil moisture decreases.1

The three most southerly zones are noted for a rich profusion of wildflowers.1
