The U.S. Fish and Wildlife Service announced Friday that approximately 1.5 million acres across six states have been designated as critical habitat for the rusty patched bumble bee, an endangered species that has seen its range shrink dramatically over the past two decades.
The designation covers portions of Illinois, Iowa, Minnesota, Virginia, Wisconsin, and West Virginia. The FWS estimates the affected areas span 33 counties, with many located near major metropolitan areas including Minneapolis-St. Paul, Chicago, Milwaukee, and Iowa City. The bee became the first federally listed endangered bee species in 2017 after populations declined across roughly half its historic range.
The critical habitat designation does not establish new reserves or change land ownership. Instead, it requires federal agencies to consult with FWS when permitting projects that involve federal funding, authorization, or oversight in designated areas. Development and other activities may face additional review if they could harm the bee's survival.
What the Right Is Saying
Some landowners and agricultural groups have raised concerns about federal overreach and potential restrictions on property use. The designation means any federally connected project in affected counties may now require additional environmental review, which critics argue could delay farming operations, infrastructure improvements, and housing development.
Property rights advocates note that while no land is being seized, the designation effectively gives the federal government a voice in local planning decisions across 33 counties spanning multiple states. Industry groups have argued that voluntary conservation measures rather than regulatory designations would achieve pollinator recovery goals without impeding economic activity.
The FWS has emphasized that habitat protections focus on preserving areas where confirmed sightings have occurred and zones with high potential for bee expansion, primarily concentrated near existing urban centers rather than rural agricultural land.
What the Left Is Saying
Environmental advocacy groups praised the designation as a long-overdue step toward protecting one of America's most imperiled pollinators. The Natural Resources Defense Council, which filed suit alongside the Center for Biological Diversity and Friends of Minnesota Scientific and Natural Areas to compel the habitat designation, called the move essential to the species' survival.
Many of its native grasslands have been wiped out, so protecting its last remaining habitat from further destruction is just common sense, said Lucas Rhoads, senior attorney at NRDC. These legal protections will help give us the best chance of recovering this once-common pollinator.
Conservation biologists note that helping rusty patched bumblebees also benefits other declining pollinators like the monarch butterfly. Jay Watson, a conservation biologist for the Wisconsin Department of Natural Resources, emphasized that providing diverse native flowers blooming from spring through fall and minimizing pesticide use can support recovery efforts across species.
What the Numbers Show
Since 2000, only 13 states have recorded confirmed sightings of the rusty patched bumble bee: Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Minnesota (which declared it its state bee), North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and Wisconsin. The species was historically found in roughly half the continental United States.
The FWS estimates approximately 1.5 million acres across six states are now designated as critical habitat. Counties included in the designation span from Boone, Ogle, and Winnebago counties in Illinois to Dane, Milwaukee, and Waukesha counties in Wisconsin, with additional areas in Virginia's Highland and Bath counties and West Virginia's Greenbrier and Pocahontas counties.
Decline factors identified by wildlife biologists include pathogens and parasites, pesticides and fungicides, habitat loss and degradation, competition from managed bee populations, climate change effects, and small population dynamics. The species was once found across 28 states before its significant decline.
The Bottom Line
The critical habitat designation represents a milestone in federal efforts to recover the rusty patched bumble bee, which has lost approximately half its historic range since 2000. Environmental groups say the legal protections are necessary given that native grasslands have been largely destroyed outside protected areas.
Landowners and developers should be aware that projects requiring federal permits or funding in designated counties will now undergo additional review. The FWS maps show high-potential expansion zones scattered across multiple states, suggesting future designations could expand further if bee populations recover.
Wildlife officials recommend that residents interested in supporting pollinator recovery can plant native flower varieties like Dutchman's breeches, eastern bluebells, wild bergamot, and milkweed species while reducing pesticide use. The effectiveness of the habitat designation will be monitored through ongoing surveys across confirmed sighting areas.
