By Jeff Nesmith WASHINGTON, DC-- Scientists have found another problem caused by rising carbon dioxide levels in the atmosphere: It'll make you itch. (Poison Ivy by Jennifer Anderson, USDA-NRCS PLANTS Database) Poison ivy not only grows much faster in a carbon dioxide-enriched atmosphere, it also produces more "urushiol," the substance that causes most people to break out in a rash, said Duke University botanist William Schlesinger. The vine's exuberant response to carbon dioxide may have unsettling implications for human health as the level of the gas in the atmosphere continues to increase, and it does not bode well for the future health of...

By Bill Thompson, III SPRING is the start of the breeding season for most of our North American birds. They pair up with mates, build nests, lay eggs, raise young, and then some of them repeat the cycle--as many as three times. There are some things that you can do to assist your backyard birds at this busy time of year. Here they are: 1. Provide water for bathing and drinking on hot days. Actually, provide water all year long, if you can -- but make sure to keep it clean. Your birdbath may be the first place in your backyard a parent bird takes its offspring. Lots of family-style bathing takes place at summer birdbaths, and young birds can be dependent upon the only water source they know. So keep your bath filled and clean. Make sure the average water depth is less than three inches. Birds appreciate shallow water. 2. If you find a nest--stay away. If you happen upon... Read On (Bluebird building

By Scott Shalaway WITH THE THREAT of frost finally over, many people head to their favorite garden center or nursery. As you shop, consider this lesson in plant ecology. Many gardeners favor showy, exotic plants but fail to consider the ecological implications of landscaping millions of small backyards. The total amount of backyard habitat in the U.S. is staggering. Though apartment dwellers may only maintain a window box or two, quarter-acre lots are common and many people maintain backyards that encompass an acre or more. (Dogwood tree) According to the 1998 Statistical Abstract of the United States, American backyards total at least 35 million of acres. That's more than 50,000 square miles of backyard habitat. Unfortunately, the typical American homeowner has been brainwashed to... Read On | ||
Strange Song Alerts Sleeper To Good News I AWOKE this morning a bit disquieted. My first conscious thought was: that doesn’t sound like a robin. Every morning from early spring until the insects take over I wake up to the song of the neighborhood robins calling up the sun. They do their work tirelessly, letting the world know to “Cheerily, cheer-up; cheerily, cheer-up; get up, get up”. It is often their melodious song and the excited whinny as they fly from spot to spot that wakes me. But this morning, the song wasn’t quite right. It was coarser, a little raspy and the notes shorter, somewhat more abrupt. It just wasn’t right. I lay there digesting this slightly different sound, then slowly it dawned on me: the...

Shouldn't Affect Wild Turkeys
THE RAIN poses concerns for wildlife agencies about future Wild Turkey populations. According to Bob Eriksen, National Wild Turkey Federation (NWTF) Northeast regional biologist, an overabundance of rain during the breeding and nesting season can cause problems, but the rain would be harder on turkey populations if it came in late May and into June. While floods can wash out nests in low-lying areas and make hens more susceptible to predators when nesting, predators and lost nests are typical hazards in the lives of turkeys. "Wild turkeys are ground nesting birds," Eriksen said. "Hens incubating their eggs are normally more... Read On Why Plant Natives? | ||
