How do the climatic characteristics of Canada's prairie region influence the type of vegetation in that region

Depending on the vegetation growing and what the climate should be for that species of plant. If it is to cold for the plant it will die meaning there would be less of it in the region. If it is to hot then it will also die. If it is to rainy or snowy then it would eventually drown. If it is perfect precipitation and climate then it will grow in bulks and be shipped all over Canada.
