Local Environmental Conditions
The landscape around Sioux Portage Group Campground is heavily wooded. In the immediate area, the surrounding woods make trees an important source. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer and keep pollen in the air into late summer. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around freezing, pollen levels are low again. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.
