Tree species native to Canada number 171 but many of these are of little or no commercial importance and also, in many cases, have a very restricted range. The maps on this plate show the ranges of the 35 species of economic importance. The range maps are similar to those used in the 1949 edition of Forestry Branch Bulletin 61, Native Trees of Canada. Shades of green indicate the ranges of the coniferous species commonly known as softwoods. The brown tints show the ranges of the broadleaved, mostly deciduous species, commonly referred to as hardwoods.
