Current and potential range maps show remaining and threatened habitats mainly in the Midwest and Northeast, with high-potential areas identified in Wisconsin, Minnesota, Iowa, Illinois, Virginia, and nearby states.

Public guidance emphasizes creating pollinator-friendly habitats with native plants and minimizing toxins to aid recovery.

Supportive actions include increasing native floral resources, reducing pesticide use, and providing nesting and hibernation sites such as leaf litter, plant stems, sticks, and grass mats in gardens and public spaces.

The May 29, 2026 designation aims to support recovery without creating new reserves or changing ownership.

The rusty patched bumble bee has experienced a dramatic range and population decline since 2000, shrinking from a widespread presence to sightings in about a dozen states, with federal listing as endangered in 2017.

A range update map and additional resources are available for readers who want more information or to participate in conservation efforts.

Hundreds of counties across 33 counties have been designated as critical habitat, notably surrounding major Midwest cities such as Minneapolis–Saint Paul, Chicago, Iowa City, and Milwaukee.

This designation builds on a long-running effort by NRDC and others to secure habitat protections for the species.

The designation targets areas across 33 counties and may influence federal planning and permitting without altering ownership.

The article notes the bee’s appearance and distinguishing features, while conservation actions focus on habitat protections and restoration rather than direct wildlife management.

In May 2026, the U.S. Fish and Wildlife Service designated roughly 1.5 million acres of critical habitat across Illinois, Iowa, Minnesota, Virginia, Wisconsin, and West Virginia to aid the bee’s recovery.

The critical habitat designations do not transfer ownership or create new reserves, but they may affect federal actions related to development, permitting, or implementation.
