The Latest: Quagga mussels invade Lake Powell

BackstoryIn the 1980s, invasive quagga and zebra mussels hitchhiked on ocean vessels from Eastern Europe to northeast North America. There, the thumbnail-sized bivalves proliferated, clogging water intake pipes, crusting boats, wreaking havoc on ecosystems and causing billions of dollars in damage. Measures were taken to prevent their westward spread, but in 2007 quaggas arrived, eager […]

Wanted: Wolves in Colorado

Being an avid elk hunter in Colorado, I hope the trapping and hunting pressure on wolves in Wyoming brings some of them here (“Wolf bycatch,” HCN, 4/29/13). The presence of wolves in Colorado might reduce the number of cattle that overgraze national forest land and ruin the riparian habitat for six months of the year, […]

Eat more insects

When I was in middle school my Dad and I were catching grasshoppers for fishing bait, but we ended up in the kitchen frying them instead. Since it’s hard to go wrong deep-frying anything, they were kind of tasty, like popcorn. In a Calvin and Hobbes-inspired move, I decided to take some to school and […]

It’s Endangered Species Day!

Today, the third Friday in May, is Endangered Species Day. Passed by a unanimously-supported Senate resolution several years ago, the holiday is intended to encourage us “…to become educated about and aware of threats to species, success stories in species recovery and the opportunity to promote species conservation worldwide.” The Endangered Species Act (ESA), which […]

What’s killing bees?

Normally, the Colorado bee swarm hotline starts ringing in mid-April. By May 1, a call is coming in every other day. And by the 15th, “somebody opens up the bee floodgates and they start swarming like the devil,” says Beth Conrey, president of the Colorado Beekeepers Association, who fields the calls on her cell phone. […]

Grizzlies back from the brink?

Grizzly bears in the lower 48 were put on the endangered species list as threatened in 1975, a time when the survival of six bear populations in Montana, Wyoming, Idaho and Washington seemed tenuous. But thanks to decades of vigilance, the bears are doing much better, with about 1,400 to 1,700 in the lower 48, […]

(Still) getting the lead out

Lead is banned in paint, gasoline, dishes, and children’s toys, and now California is looking at removing the largest unregulated source of the neurotoxin by also banning lead ammunition. One motivation is to generally protect wildlife and human health, but some see it as a way to improve the prospects of California condors; lead poisoning […]

Look! Shooting stars!

My favorite Oregon wildflowers are called shooting stars, delicate darts whose blossoms with their sharp-pointed anthers and swept-back magenta petals seem to hurtle toward the soft spring earth from their height of six inches or so. These are among the first flowers to appear in our oak woodlands, long before the oaks themselves show any […]

Real bears get a helping hand from Hollywood

It’s a long way from the cold, rainy valleys of northwestern Montana’s Cabinet Mountains to the bright lights of Hollywood. But they are both bear country, in very different ways. Hollywood is about myths — taking old myths and digging them deeper. Grafting on new, odd branches to existing myths. Hollywood plays to the mythology […]

Black-backed woodpeckers and severe fire

A charred forest is an eerie place, even years after a wildfire. I discovered this last summer while backpacking through Northern California’s Lassen Volcanic National Park. Dead trunks creaked as they swayed in the wind, their branches clacking against each other like bones. We moved quickly, as if walking past an avalanche-prone slope. Had we […]
