"The research for these plant hardiness maps was made possible through a collaborative effort by scientists at Natural Resources Canada's Canadian Forest Service, Environment Canada, and Agriculture and Agri-Food Canada". Contents: Canada's plant hardiness zones = Zones de rusticité des plantes au Canada -- Extreme minimum temperature zones = Zones de temperature minimale extreme -- Arboreal emblems of Canada = Emblèmes arboricoles du Canada. "This third edition of the plant hardiness zones map shows the different zones in Canada where various types of trees,shrubs and flowers will most likely survive. The map is based on a formula using seven important variables that influence plant survival. ... The original map was developed by Agriculture and Agri-Food Canada in the early 1960s based on average values from 1930 to 1960. This new map uses 1981 to 2010 averages. The map shown at right and on the reverse shows an alternative plant hardiness zone approach using just one climate variable: the average of the annual extreme minimum temperature for the period 1981 to 2010. This approach was originally developed by scientists at the United States Department of Agriculture." Text in English and in French.
