Colorado Suburb Doubles as America's First Pollinator Haven

Bees, butterflies, and beetles are moving into a Colorado neighborhood by the thousands, and neighbors couldn't be happier about it.

Baseline, a mixed-use community in Broomfield, Colorado, became the world's first certified pollinator district in 2019. The concept is simple: build homes while creating thriving habitats for the pollinators that keep our food systems and ecosystems alive.

The results have been stunning. When construction began, scientists counted only 11 pollinator families visiting the area. By summer 2025, that number jumped to 27 different families, with individual pollinator counts soaring from 587 in 2023 to 3,805 in 2025.

The community spans 1,200 homes with prices starting in the low $500,000s, slightly below Broomfield's median home price. But affordability isn't the only draw.

Every home sits within a five-minute walk of a pocket park. Bike paths and trails wind through 170 acres of native, drought-tolerant gardens designed specifically for pollinator habitats. All units meet strict energy efficiency standards too.

The nonprofit Butterfly Pavilion created the pollinator district concept to address the crisis facing bees, butterflies, moths, and beetles. These species don't just make honey or look pretty. They pollinate the plants that produce our food, filter our water, prevent soil erosion, and keep entire ecosystems functioning.

"They keep wetlands going. They keep our grasslands going. They make sure forests are diverse," Amy Yarger, director of horticulture at Butterfly Pavilion, told the Colorado Sun. Without them, we risk losing the plant communities that prevent dust bowls and keep our environment stable.

The Ripple Effect

The model is spreading fast. Cities like Manitou Springs and Lafayette have committed to creating their own municipal pollinator districts. Butterfly Pavilion experts are working with communities across Colorado's Front Range to transform transportation corridors and neighborhoods into pollinator havens.

Western honeybee populations alone increased 272% at Baseline in 2025 compared to the previous year. Scientists documented broadtail hummingbirds for the first time, along with longhorn beetles, plasterer bees, and digger wasps.

Residents have embraced their role as pollinator stewards. Yarger says homeowners regularly stop her during surveys to share what they've spotted. "They have ownership in that," she told the Colorado Sun.

The certification process requires ongoing scientific monitoring, with experts documenting current conditions and providing recommendations for optimal pollinator management. Infrastructure can absolutely support biodiversity when guided by science and commitment.

For Yarger, watching the transformation unfold makes her feel "like we have a way forward."
