The 2010 Plant Hardiness Zones of Canada outlines the different zones in Canada where various types of trees, shrubs and flowers will most likely survive. It is based on the average climatic conditions of each area. The first such map for North America, released by the United States Department of Agriculture in 1960, was based only on minimum winter temperatures. In 1967, Agriculture Canada scientists created a plant hardiness map using Canadian plant survival data and a wider range of climatic variables, including minimum winter temperatures, length of the frost-free period, summer rainfall, maximum temperatures, snow cover, January rainfall and maximum wind speed. Natural Resources Canada's Canadian Forest Service scientists have now updated the plant hardiness zones using the same variables and more recent climate data (1961-90). They have used modern climate mapping techniques and incorporated the effect of elevation. The new map indicates that there have been changes in the hardiness zones that are generally consistent with what is known about climate change. These changes are most pronounced in western Canada. The new hardiness map is divided into nine major zones: the harshest is 0 and the mildest is 8. Subzones (e.g., 4a or 4b, 5a or 5b) are also noted in the map legend. These subzones are most familiar to Canadian gardeners. Some significant local factors, such as micro-topography, amount of shelter and subtle local variations in snow cover, are too small to be captured on the map. Year-to-year variations in weather and gardening techniques can also have a significant impact on plant survival in any particular location.

WMS

A compliant implementation of WMS plus most of the SLD extension (dynamic styling). Can also generate PDF, SVG, KML, GeoRSS

Created for distribution by the GeoYukon application as a comprehensive resource for all publicly available First Nation Land information in the Government of Yukon. This data may be used directly by other applications to dynamically display Yukon data; however, it may be subject to change as data sets are updated or added.

Grids surveyed is a polygon feature class containing the 5’ latitude by 5’ longitude grid cells surveyed for all seasons combined including the grids that were surveyed but where no species were seen. In order to produce maps for a specific season a selection for these grids must be performed. / Classe d’entités polygonales renfermant les carrés du quadrillage de 5° de latitude par 5° de longitude visés par les relevés, toutes saisons confondues, y compris les carrés ayant fait l’objet de relevés, mais dans lesquelles aucune espèce n’a été observée. Afin de générer des cartes pour une saison en particulier, il faut faire une sélection parmi ces carrés.
