The climate of the part of Bruce County in the Lake Huron-Georgian Bay region is slightly modified by the presence of Lake Huron and Georgian Bay. The winter temperature is 23°F and spring temperature ranges from 38°F to 39°F. Summer temperatures are usually 64°F while fall temperatures average between 47°F and 48°F. The frost-free period is approximately 147 days and the growing season varies from about 186 days at Tobermory to 196 days at Kincardine. The annual rainfall varies from about 31 inches in the north to 35 inches in the south and the annual snowfall varies from 80 to 110 inches. The part of Bruce County in the Western Uplands region does not enjoy the moderating influence of the Lake and has a lower winter temperature and a slightly higher summer temperature than the Lake Huron-Georgian Bay region. The mean annual temperature is 44°F and the summer temperature is 65°F. The average length of frost-free period is from 130 to 140 days. The growing season varies from 182 days to 195 days, being shortest in the northern part of the County. The mean annual precipitation is approximately 36 inches, over half of which falls during the period of May 1 to October 1. Snowfall varies from 100 to 120 inches. From the above data it would seem that the amount and distribution of rainfall is satisfactory for general farm crops. There is little likelihood of drought and the weather is.usually favorable during the harvesting season.

Once the vegetation becomes established it exerts considerable influence on soil formation. In classifying and mapping soils, those features which can be observed in the profile are used as criteria for making type separations. It is impossible to determine to what extent such features have been influenced by vegetation since it is only one of several soil forming factors. Neither is it the purpose of the soil survey to make a vegetation survey nor present a plant ecology report of an area. However, a study of the natural vegetation in an area is desirable so that the soil profile may be more carefully interpreted. Certain associations of trees occur more frequently on some soils than on ot#hers. According to Halliday” Bruce County is included in the Huron-Ontario section of the Great Lakes-St. Lawrence Forest, Region. In this section the prevailing association is broad-leaved, with sugar maple and beech dominant. With them are basswood, white elm, yellow birch, white ash and some red maple. Small groups of hemlock, balsam fir and the occasional white pine -- -.~- ..___- *Hallidav .- \I’ . II:. II.. :I Foist Classification of Canada, Forest Service Bulletin No. 89. 27
