Latest Old-growth forest Stories
A study led by anthropologist Christopher I. Roos from Southern Methodist University in Dallas shows that modern “mega forest fires” in the southwestern U.S. are the result of dense canopies that likely grew as a result of human interference.
Big trees three or more feet in diameter accounted for nearly half the biomass measured at a Yosemite National Park site, yet represented only one percent of the trees growing there.
After unearthing a previously unknown portion of one of the planet’s earliest known forests, archeologists say the fossils of 385-million-year-old trees reveal a far more diverse ecosystem than researchers had previously thought existed.
Three of the world's subspecies of tigers are now extinct. A new study found that the Sumatran tiger subspecies is nearing extinction as a result of human activities, particularly the conversion of natural forests into forestry and agricultural plantations, leading to habitat loss.
Many tropical forests are extremely rich in nitrogen even when there are no farms or industries nearby, says Montana State University researcher Jack Brookshire.
Studies of ant populations in Borneo reveal an unexpected resilience to areas of rainforest degraded by repeated intensive logging, a finding which conservationists hope will lead governments to conserve these areas rather than allow them to be cleared and used for cash crop plantations.
Researchers have assessed the impact of disturbance and land conversion on biodiversity in tropical forests.
A comprehensive assessment of tropical forest management reports a 50 percent increase in the area of tropical forest under sustainable management in just five years, but cautions that key drivers of that increaseâ€”growing demand for certified timber and funding for climate change initiativesâ€”could have only a marginal impact in the long-term.
The 25-story construction crane used since 1995 to investigate such things as how Pacific Northwest forests absorb carbon dioxide, obtain sufficient water and resist attacks by pests and diseases is being pruned back to just the tower.
The Allegheny National Forest is a National Forest that can be found in northwestern Pennsylvania. The forest covers 513,175 acres of land. In the forest is the Kinzua Dam, which impounds the Allegheny River to create Allegheny Reservoir. The administrative headquarters for the Allegheny National Forest can be found in Warren. It has two ranger stations, one in Bradford, McKean County and one in Marienville, Forest County. The forest lies in the heart of Pennsylvania’s oil and gas...
Clearcutting, otherwise known as clearfelling, is a controversial forestry/logging practice in which the majority or all of the trees in an area are uniformly cut down. Clearcutting, in addition to shelterwood and seed tree harvests, is utilized by foresters to construct certain types of forest ecosystems and to encourage select species that require plentiful sunlight or grow in large, even-age stands. Logging companies and forest-worker unions in certain countries support the practice for...
