The use of dense mixed- wood increased with windchill (/' = and respectively) (Figure 6). In contrast, the use of dense softwood decreased with windchill (r = ). Cover Use and Rain Decreased use of dense mixedwoods (r = ) and increased use of hardwoods (r - ) and softwoods (r = ) occurred when the weather changed from clear to rain in summer. The same trend occurred in the winter of 1969-70 when winter rainfall was abnormally high, but there was no clear trend in the 1970-71 and 1971-72 winters, possibly due to the lower rainfalls and the effect of deep Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ottawa Field-Naturalists' Club.
