Column One: Carnivorous plants losing ground in the U.S.

Scientists are on the trail of the little-understood meat-eaters like the California cobra lily and Venus’ flytrap, in decline amid rampant poaching and other human encroachment.

Reporting from Quincy, Calif. —

“This is the easy part,” says Barry Rice, half-sliding, half-falling down a ravine through a latticework of dead branches.

Decades ago, lush stands of Darlingtonia californica — emerald plants coiled like fanged cobras ready to pounce — grew at this spot in the northern reaches of the Sierra Nevada.

Deep in the ravine, the air is hot and dead. Pieces of bark that have sloughed off trees make every step a danger — nature’s equivalent of a thousand forgotten skateboards cluttering a driveway. Slate tinkles underfoot, and the ground feels like stale angel-food cake: stiff yet porous.

Rice, a botanist at UC Davis, is not the first to hunt the cobra lily here in Butterfly Valley. In 1875, amateur botanist Rebecca Austin fed the plants raw mutton and carefully observed how they digested it.

Yet to this day, much of the plants’ biology and habitat remain unknown — which is why Rice is here, trying to find established populations.
