Top Allergens in South Dakota
The most common allergens affecting residents of South Dakota, ranked by severity and seasonal impact.
Short Ragweed (Ambrosia artemisiifolia)
SevereRagweed dominates South Dakota's eastern prairie and agricultural margins. The fall season runs from late July through the first hard frost, producing the state's most symptomatic allergy period.
Cottonwood (Populus deltoides) Pollen
SeverePlains cottonwood is the signature riparian tree across South Dakota's river valleys. April–May pollen release is heavy along the Missouri, James, and Big Sioux rivers.
Russian Thistle / Tumbleweed (Salsola tragus) Pollen
ModerateRussian thistle thrives in South Dakota's dry, disturbed western soils and Badlands margins, co-peaking with ragweed for a heavy late-summer weed pollen season.
Kentucky Bluegrass (Poa pratensis) Pollen
SevereBluegrass is the dominant cool-season turf and pasture grass across South Dakota. Grass pollen peaks in June and creates the primary early-summer allergen exposure.
American Elm (Ulmus americana) Pollen
ModerateAmerican elm is one of the earliest spring pollen producers in South Dakota towns and shelterbelts, releasing pollen as early as March during warm spells.
Sagebrush (Artemisia spp.) Pollen
ModerateBig sagebrush and prairie sage are common in western South Dakota's rangeland, adding to the late-summer weed pollen burden alongside ragweed and Russian thistle.

Why Allergies Are Worse in South Dakota
South Dakota's Continental climate splits the state into Black Hills conifer forest in the west and vast prairie-farmland in the east, with the Missouri River corridor connecting both allergy regions.
Black Hills Ponderosa Pine & Juniper
The Black Hills contain the largest ponderosa pine forest east of the Rockies, plus Rocky Mountain juniper that produces early-spring pollen affecting Rapid City and the western corridor.
Eastern Plains Ragweed & Cropland
South Dakota's eastern farmland — corn, soybeans, and fallow margins — provides ideal ragweed habitat. Sioux Falls and Aberdeen experience some of the state's highest fall pollen counts.
Badlands Dust & Russian Thistle
The semi-arid Badlands and western rangeland produce windblown dust and Russian thistle pollen that compound respiratory symptoms during late summer.
