Why Allergies Are Worse in Fort Collins
Fort Collins sits where the Cache la Poudre River exits the foothills at 5,000 feet, creating a natural cottonwood-lined pollen corridor through the heart of the city.
Poudre River Riparian Corridor
The Cache la Poudre River supports dense cottonwood gallery forests that channel heavy spring pollen directly through Fort Collins neighborhoods and downtown.
Foothill-Plains Transition
Fort Collins sits at the transition between Front Range foothills and high plains, receiving both mountain tree pollen and prairie grass pollen on shifting winds.
Semi-Arid Climate
Low humidity and over 300 days of sunshine at 5,000 feet dry out nasal passages, increasing susceptibility to airborne cottonwood and grass pollen.
Irrigated Turf Expansion
Fort Collins' growing suburban development and irrigated landscapes sustain Kentucky bluegrass pollen production well beyond what the natural semi-arid climate would support.
