New Hampshire is the second most forested state in the country, but according to our guest today, UNH Professor and Ecologist, Scott Olinger, our forests face serious challenges from climate change to invasive species. Today on the Exchange, we're looking at what's happening to our trees, what cane be done to protect them and the environmental significance of our forests.
Despite arguments over effectiveness and cost, New Jersey has long practiced what is called “artificial beach nourishment”—importing and pumping tons of sand to build up its shore. Much of that sand was swept away by super storm Sandy’s massive surge and the one that followed from the recent nor’easter.
A 2004 poll estimated that thirteen percent of American households keep goldfish. Nearly 500 million are sold each year just to feed other pets. How goldfish became America’s go-to pet is a matter of some debate.
Dear EarthTalk: I have heard that fracking is becoming a major environmental issue in the U.S. Which parts of the country are already hosting fracking operations? Are there efforts underway to stop the practice in specific states or across the country?
More than three decades ago, the Mountain Gorilla project started a tourism project to save the threatened gorilla population from poaching. The project hired poachers as park rangers and demonstrated that live gorillas were much more valuable as tourist attractions than dead ones. Since then, gorilla tourism has added hundreds of millions of foreign tourist dollars to state coffers in Central Africa, and the great ape populations have seen a modest rebound.
Generations ago, when people lived closer to the natural world, more outdoors than in, mild October days were called "bluebird weather. "The eastern bluebirds' gentle, quizzical notes were familiar and their distinctive habits recognized. A bluebird family remains together this time of year when most other bird species disperse. They favor field or open habitat, and typically perch on branches at field edge when they feed. Family members take turns dropping down to the ground then return to perch, one after another, most likely in pursuit of grasshopper or cricket.
Dear EarthTalk: The federal government recently designated the Connecticut River watershed as the nation’s first “National Blueway.” What is a National Blueway and does such a designation come with any funding for conservation or other purposes?
Henry David Thoreau's death 150 years ago has inspired memorial events in Concord - the Massachusetts Concord - but Thoreau passed through our Concord on a trip by boat and foot that led to his first book.
The bird world quiets down by late summer - but not the American goldfinch, one of the most common backyard birds. September brings the chatter of young goldfinches as they follow their male parent. They beg noisily, perched with head thrown back and trembling wings.
Most songbirds switch their diet to high-protein insects when feeding their young, and they nest earlier when insects are most bountiful. For example, chickadees that keep bird-feeders busy in winter disappear in summer as they forage for insects not birdseed.
