Do you believe small local conservation efforts can effectively help save endangered species in your area?

A student identified a rusty patched bumblebee on the University of Iowa campus during summer 2026. This critically endangered species has seen its population decline by 90 percent since 2000.

Why it matters

Conservationists hope that small-scale local efforts will help reverse the decline of a species that now occupies only one percent of its historic range. These bees are essential for pollinating crops such as strawberries, tomatoes, and peppers.

The rusty patched bumblebee currently occupies just one percent of its historic range. Researchers estimate the total species population has plummeted by 90 percent since 2000.

The players

University of Iowa

This educational institution manages campus landscaping and is an active affiliate of the Bee Campus USA program.

Bee Campus USA

This national organization provides a framework for universities to protect native pollinators through habitat conservation.

The details

The sighting occurred near the Iowa Memorial Union footbridge, marking a rare appearance for the insect. The University of Iowa supports local populations through its Bee Campus USA affiliation, which includes planting native gardens and reducing pesticide usage.

Since 2000, the bumblebee population has decreased by approximately 90 percent.
The rusty patched bumblebee was designated critically endangered in 2017.
The University of Iowa affiliated with Bee Campus USA in 2022.

The Big Picture

The rusty patched bumblebee’s status as a critically endangered species follows the conservation mandates established by the Endangered Species Act of 1973.

Local residents can support these conservation efforts by planting native flowers in their own gardens to provide essential food sources for pollinators. These actions help create connected habitats that assist in the recovery of endangered species like the rusty patched bumblebee.

The takeaway

Maintaining native plant species in urban landscapes is a crucial step in supporting threatened insect populations. Residents can contribute to regional biodiversity by avoiding the use of chemical pesticides in their yards.
