There’s a strange bee called the alkali bee. And in one small valley in Washington, it’s worth its weight in gold.

In Walla Walla Valley, farmers depend on alkali bees, a native species essential to one of the country’s most overlooked crops: alfalfa seed. In fact, the work of these tiny pollinators generates millions of dollars in agricultural revenue. Unlike honey bees, alkali bees take a pollen-packed smack to the face without hesitation, powering through millions of flowers with speed and precision. But alkali bees can’t be boxed, transported, or bought. They nest in the ground, require salt-crusted soil, precise irrigation, and near-perfect conditions to thrive.

In this episode of Human Footprint, Shane Campbell-Staton visits the only place on Earth where solitary, ground-nesting bees are managed for large-scale agriculture. He meets third-generation farmer Mark Wagoner and entomologist Doug Walsh, who’ve each played a role in transforming this agricultural landscape into a living partnership with native pollinators.

Shane uncovers the extraordinary steps to keep these bees alive: building salt-encrusted bee beds, spraying pesticides late at night, and even rerouting a state highway. But supporting alkali bees is more than just innovative farming, it’s a glimpse into what it might take to protect WILD pollinators in a world built for honey bees.
