Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the ranges of a few of the many thousands of insects, ticks and spiders species that are found in Canada. There are 20 maps showing the ranges of 52 separate species. Ranges depend on the distribution of suitable...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the vegetation regions, and 19 smaller-scale maps showing distributions of particular plant species. The main map shows the distribution of 17 natural vegetation types and also shows non-vegetated areas (existing...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the extent of forest regions of Canada. It displays the extent of forest regions of Canada under natural conditions. Therefore, although many parts of Southern Canada are no longer forested, no attempt has been...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the portions of land in four condensed maps which illustrate the kind of forest maps that were being prepared from air photographs with a minimum of groundwork by the Forestry Branch of the Department of Northern...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows 20 condensed maps of tree species native to Canada. There are 171 different species, but many of these are of little or no commercial importance in addition to, in many cases, having a very restricted range. The...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows 20 condensed maps with only mammals that are well-known to Canada. The ranges, for the most part, indicate present and usual distribution. The rare or occasional occurrences have not been shown. As there is still...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows 20 condensed maps with the more popular game birds in Canada. The ranges, for the most part, indicate present and usual distribution. Rare or occasional occurrences have not been shown. As there is still much to be...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows 20 condensed maps with ranges of important inland fish of commercial value found within Canada.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map showing general distribution in nine condensed maps of the certain species of East Coast fish, mollusks, crustaceans, and indicates the areas of greatest catches and amounts taken for most species. These maps are based...

A simulation of projected changes in mean annual precipitation from the period 1975 to 1995 to the period 2040 to 2060, is shown on this map. On average, precipitation increases, but it is not evenly distributed geographically. There are marked regions of decreasing, as well as increasing...

Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate showing general distribution in eight condensed maps of the certain species of West Coast fish, mollusks, crustaceans, and indicates the areas of greatest catches and amounts taken for most species. These maps are based...

A simulation of projected changes in mean annual precipitation from the period 1975 to 1995 to the period 2080 to 2100 is shown on this map. On average, precipitation increases, but it is not evenly distributed geographically. There are marked regions of decreasing, as well as increasing...

A simulation of projected changes in annual mean temperatures from the period 1975 to 1995 to the period 2040 to 2060 is shown on this map. According to this projection, the Arctic would experience the greatest annual mean warming followed by other areas in northern Canada and central and...

A simulation of projected changes in annual mean temperatures from the period 1975 to 1995 to the period 2080 to 2100 is shown on this map. Geographically, the temperature changes would not be evenly distributed. According to this projection, the Arctic would experience the greatest annual mean...
