The mountain lion known as P-47 survived fires, freeways and hostile ranchers. But in March, the 3-year-old big cat—tracked by California biologists since his kitten days—succumbed to a hidden hazard: an insidious form of food poisoning. Six anticoagulant compounds—chemicals used to kill rodents...

As my beloved seedlings languished untouched on the display table, I improved my sales pitch: “Would you like a late-flowering thoroughwort to help migrating butterflies refuel? What about an aster that’s the only pollen source for some bee species?” But unlike the animals who would devour these...

It’s a peculiar rite of modern homeownership: Plant a tulip bulb in autumn, cage or spray it to deter nibblers, admire its fleeting blooms a few months later, let it rot in soil ill-suited to its needs and repeat the whole cycle again the following year.

As a new homeowner susceptible to sales pitches from the garden industrial complex, I spent my early planting years salivating over glossy magazine spreads exploding with color and texture and promises of endless summers. “Flower porn” was how my husband described those lushly photographed...

The delegate seemed ready to pick a fight, already having mocked a proposed plastic bag ban and other pro-environment bills on the day’s agenda. As I finished my testimony in support of wildlife-friendly plantings, I steeled myself for a heated debate. But on that gray afternoon in February 2020...

It seemed like a good idea at the time: Buy a house with a two-acre property, let our energetic herding dog have the run of the place and spend blissful summer days digging side by side in the dirt with her. And it was blissful, watching Mattie carve out her napping spots behind the ferns and tall...

Following one former lab worker's path to advocacy.

On summer evenings, my husband and I head to the darkest spot of our property to look for the light—in the form of fireflies rising from meadow grasses and twinkling their way into the trees. As the tulip poplars behind this spectacular display settle in for slumber, white yucca flowers open their...

Longtime Trust friend Fred Ziegler became the first founding member of the Humane Stewardship Alliance, pledging to follow humane stewardship principles in managing his nearly 2900 acres in Tennessee. With three streams and 1.5 miles of frontage along one of North America’s most biologically rich...

Teddy was never meant to have a name. He was born a number, just one of tens of thousands of dogs—mostly beagles like him, chosen for their trusting, docile nature and compact size—bred in the United States for use in experiments each year. Teddy was meant to live and die in a laboratory, without...

For wildlife on a beautiful 32-acre property in Mount Airy, Maryland, life is sweeter—and safer—because of the pledge landowners Jennifer Bevan-Dangel and Andrew Dangel made to follow the Humane Stewardship Alliance’s humane stewardship principles in managing their land. Lands of all sizes can be...

It began, almost certainly, in a bat. Then, just as SARS jumped to civets from bats, the virus that causes COVID-19 passed to another mammal, possibly a pangolin. Finally, late last year, the new coronavirus most likely jumped to humans in a wildlife market in Wuhan, China, a densely populated city...

While soaking her raised beds in preparation for tomato planting last summer, Gail Goldman was startled to see a tiny, waterlogged creature pop up out of the soil. Later another one briefly poked out his head. “Basically, I was watering shrews,” the Seattle gardener says of her foiled vegetable...

They inhabit the ruins of a 14th-century empire in Africa, cling to 800-year-ol cliffside dwellings in Arizona, forage in old Indian temples and European churches and occupy the decidedly less grand crawl spaces of our modern homes. As the world’s only true flying mammals, bats know how to get...

It starts out mildly enough: Heading to work on the subway, you realize you forgot your wallet. No big deal, you think. I’ll borrow money to get home. Soon the lights go out and the train hurtles toward the sky, speeding through the atmosphere. Time passes—it’s hard to tell how long. The subway is...

WASHINGTON —Today, the Humane Society of the United States and Humane Society Legislative Fund filed a petition with the Food and Drug Administration requesting that the agency updates regulations to make clear that animal testing is not legally required for drug approval. The petition also requests...

Many Marches ago, as I mindlessly contorted myself to pull a deep-rooted weed from the garden patch, my thoughts turned longingly to the smell of fresh basil that would eventually grace what I saw as a still-barren vegetable graveyard. This spot was not so lifeless as it appeared, I would soon learn...

Update 3/27/19: Dow AgroSciences ( Corteva Agriscience ) has officially agreed to release the beagles to our shelter partner, Michigan Humane Society. We are so grateful to each and every one of you who spoke up and took action to save these dogs. As we celebrate their freedom, our work is far from...

To experience the natural world, we often navigate congested highways to swim in the sea, fly over patchworked terrain to hike through preserved forests and climb distant mountaintops to catch rare views. Largely because of our ever-increasing mobility, the areas nearest to us are rarely the dearest...

To most people, the tiny voices rising above the din of traffic would have registered as everyday birdsong. But to Lori Thiele’s finely tuned ears, the high-pitched staccato emanating from a neighbor’s yard last spring was unmistakable, a sure sign of distress. “I was getting ready to go out on a...
