Data specification: Plant Hardiness Zones 1. OVERVIEW 1.1. Informal description The Plant Hardiness Zones map 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. 1.2.

NOTE: The term specification scope originates from the International Standard ISO19131. Specification scope does not express the purpose for the creation of a data specification or the potential use of data, but identifies partitions of the data specification where specific requirements apply.

Lineage statement Lineage Statement Scope 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 frostfree period, summer rainfall, maximum temperatures, snow cover, January rainfall and maximum wind speed. The original Plant Hardiness Zones 1967 dataset calculates a hardiness index based on 640 locations across Canada, and hand drawing general zones between stations. The 1967 map was developed using data from the time period of 1930-1960. This dataset does not cover northern Canada where station data were unavailable from 1930-1960.

Lineage Statement Scope Plant Hardiness Zones 2000 is the result of a collaborative effort between Agriculture and Agri-Food Canada and Natural Resources Canada (Canadian Forest Service) using improved climate models and more recent data (1961-90). The original Plant Hardiness Zones dataset calculated a hardiness index based on just 640 locations across Canada, and hand drawing general zones between stations. The new dataset is produced using climate models that incorporate long-term climate factors that affect plant survival, over a 2km gridded surface across the country. These models also take elevation into account. A missing section of the Island in northern Hudson Bay was patched by converting the same island from the National Scale Frameworks 1:1M Islands (from the hydrology dataset) to a conditional raster (1= true, 0 = false where the island data = 1) and using the Spatial Analyst CON tool to swap out the original data with the new island data.
