Local Environmental Conditions
Marie Louise Lake Campground is surrounded mainly by woodland, which covers around 54% of the nearby area, with a good deal of open water. Close to Marie Louise Lake, lakeside trees such as poplar add to local tree pollen. Maple, poplar and birch are among the allergenic trees nearby. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree pollen peaks in late spring, when the weather warms to around 10°C and maple, poplar and birch are in full flower. Grass pollen follows, peaking in midsummer and easing off by early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around freezing, pollen levels are low again.
