Why the Endangered Species Act can’t save whitebark pines

(High Country News) – U.S. Forest Service research ecologist Bob Keane has studied whitebark pine, a coniferous tree of the high country, for more than thirty years. Still, when asked to describe a whitebark to someone who’s never seen one, he takes a breath and pauses for a moment. “Gosh,” he says.
The shape of the tree is very distinctive, Keane says. Instead of growing cone-shaped like other conifers, whitebarks branch like hardwoods. “A lot of the undergrowth is very small, so you see these open park-like stands of beautiful spreading trees,” he says. This shape is an adaptation that shows Clark’s nutcrackers flying past that a tree below has many nutritious cones and might be worth a travel stop.
Clark’s nutcrackers cache thousands of whitebark seeds, dispersing the pine across the high country, where the tree is a keystone species. Whitebark pine is one of the first trees to break ground after a fire, thanks to those nutcrackers, and it stabilizes soil and snowpacks at timberline. Living a millennium or more, whitebarks shape the West’s high mountain ecology in countless ways.But the whitebark is going extinct and the U.S. Fish and Wildlife Service (the agency) hasn’t given the species federal protection under the Endangered Species Act. In April 2017, two conservation organizations from Montana lost a lawsuit against the agency for its failure to list the pine. No one – not the plaintiffs, defendants, or panel of judges from the 9th Circuit Court of Appeals – questioned the precariousness of the tree’s fate. At question was how the agency prioritized which species it protects. Species, the court ruled, could be passed over because the agency didn’t have the necessary funds. As the story of whitebarks demonstrates, extinction has as much to do with politics as it does with biology. [more]
