Summary
Canada's plant hardiness zones are evolving and show dramatic changes across much of the nation. There are two types of plant hardiness models (maps) used for plant selection decisions in Canada - a multi-climate variable model originally developed by Agriculture Canada in the 1960s and the extreme minimum temperature model developed by the US Department of Agriculture (USDA). We have recently published an update to both of these maps/models in the prestigious journal BioScience.
In this talk I will review the history of plant hardiness zones in Canada and describe changes in the zones over the last 50 years. The updated maps show clear northward shifts in hardiness zones across western Canada. Shifts are somewhat less dramatic in southeastern Canada, with modest increases in zone values associated with the Canadian map and (perhaps surprisingly) modest declines associated with the USDA approach. Old and new plant hardiness zones for any community can be found on the plant hardiness web site: http://planthardiness.gc.ca. Species-specific climate envelope models are an alternative to generalized hardiness zones and are also available on the web site. We also illustrate climate habitat changes for 62 northern tree species over the same 50-year interval and found an average northward shift of 57 kilometers. While these changes signal a possible increase in the productivity and diversity of plants that can be grown in Canada, trends in late spring frosts and other factors that may limit successful plantings will be discussed.
