Wolf pups, and the return of wild wonder
California’s fall from grace hit me in 2007, at around 9,000 feet in the Sierra Nevada. A friend and I were returning from a backpacking trip, still about a mile-and-a-half deep in the Mokelumne Wilderness, when a stroller rattled around a bend in the trail, its tiny passenger jabbering away as Dad navigated the rocky […]

Fish and Wildlife declines to list wolverines as endangered
Not enough evidence of climate harm to list wolverines, says Fish and Wildlife Climate change is a real force disrupting wildlife populations. But for the 300 or so wolverines living in the lower 48, there’s still not enough evidence of present or future danger to protect them under the Endangered Species Act, the U.S. Fish […]

Is Canada’s massive mine waste spill a sign of things to come?
From behind a screen of trees, it comes as a dull roar: A gray churn of water and debris that overtops roads, snaps trunks, carves chunks of earth from banks as if they were butter. It looks like a flash flood, something you’d see coursing from the mouth of a redrock wash in Utah, a […]

Short-sighted snowmen
Do recreational snowmobilers care enough about the future of their sport to lobby for global reduction of greenhouse gas emissions (“Snowmobiling for science,” HCN, 6/9/14)? Snowmelt is occurring earlier every year, and that is directly attributable to global warming. While snowmobilers are worrying about “large closures,” they ought to worry even more about shorter and […]

In Southcentral Alaska, salmon declines are pinned on a toothy invader
Earlier this month, I wrote about the Yukon River’s chinook salmon runs, which have lately plummeted for reasons that remain murky. While researchers are years from cracking that mystery, the Yukon isn’t the only Alaskan river losing its salmon. In the state’s Susitna River basin, which courses through Southcentral Alaska near Anchorage, the mighty fish […]

Every year, the rufous hummingbird – a tiny fire-colored ball of feathers that weighs just three grams – flies up to 3,900 miles from its winter home in Mexico all the way to Alaska. At about three inches long, the rufous takes one of the longest migratory journeys of any bird its size. Over the past several […]

Grasshopper plagues: agricultural nightmare or ecological boon?
In early June, meteorologists at the National Weather Service in Albuquerque, New Mexico, were puzzled: There was a big splotch on the radar that didn’t look like any weather system they’d ever seen. Maybe their software had a bug? Turns out, the dark green blob hovering over Albuquerque wasn’t a software glitch at all but […]

The Latest: Interior commits to restoring bison on select lands
BackstoryJust a few free-roaming bison herds remain in the West. Roughly 4,000 bison inhabit Yellowstone, but they are hindered by ranchers who fear they spread brucellosis, which can cause cattle miscarriages. The park and state agencies limit the herd’s roaming and remove “excess” animals by hunting, slaughter and transplanting to other areas (“The Killing Fields,” […]

Interior commits to bison restoration – but offers few specifics
Bison have pretty much been “odd ungulate out” when it comes to restoration efforts. Deer and elk are found throughout the West, and bighorn sheep and mountain goats are relatively widespread as well. But there are just a handful of free-roaming, genetically pure herds of bison in North America – today most of the gigantic, […]
