Plant hardiness zone (McKenney, D.W., Pedlar, J.)
Canada´s plant hardiness zones are well known to Canadian gardeners. The original hardiness indices and zones were developed in the early 1960´s through regression models of several climatic parameters and plant survival data from numerous locations across the country. Since that time Canada´s climate has changed and climate interpolation techniques have improved. These zones have been remapped using data from the original period (1930-1960), for the period from to 1961-1990, and again for the period 1981-2010 using thin plate spline interpolation methods.
