| Abstract | (unpublished)
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:
1. Monthly mean of the daily minimum temperatures of the coldest month
2. Mean frost-free period (above 0°C) in days
3. Amount of rainfall from June to
November
4. Monthly mean of the daily maximum temperatures of the warmest month
5. A winter harshness index related to rainfall in January
6. Mean maximum snow depth
7. Maximum wind gust in 30 year period
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 side 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
(www.usna.usda.gov/Hardzone/).
