GARDNERVILLE, Nev. — A botanist gently strokes the pollen of endangered wildflowers with a paintbrush as she tries to reenact nature inside a small greenhouse in the shadow of the Sierra Nevada.
It's part of a lithium mining company's grand experiment intended to help keep an extremely rare desert plant from going extinct in a yearslong battle that has set one green agenda against another: clean energy versus native biodiversity.
Australia-based Ioneer says the mine it wants to dig in the Nevada desert would more than quadruple U.S. production of lithium needed to speed production of electric vehicles and build the batteries needed for other clean electricity projects.
Conservationists proclaim their support for world leaders who are trying to tackle climate change by curbing global emissions. But they're fiercely fighting the mine because it would dig deeper than the length of a football field near the world's only known patches of land where endangered Tiehm's buckwheat grows.
So far, the U.S. Bureau of Land Management has endorsed the company's latest strategy, which includes propagating and transplanting the buckwheat, as its preferred alternative in a draft environmental impact statement, one of the last steps toward final approval of the mine. The plan still must be reviewed by the Fish and Wildlife Service, which has raised concerns about earlier versions.
Conservationists contend that mining would eradicate the plant from its current habitat and that the efforts to transplant the greenhouse-grown specimens to reclaimed mined areas are unproven.
It could take centuries, they say, to know if researchers have successfully found the delicate balance of pollinators, climate, soil conditions and minerals to make propagated Tiehm's buckwheat permanently viable in the wild.
''This latest plan for Rhyolite Ridge Mine is just greenwashing extinction,'' said Patrick Donnelly, the Center for Biological Diversity's Great Basin director, suggesting supporters are being deceptive about how environmentally friendly the plan is.
