Handful Of Heavyweight Trees Per Acre Are Forest Champs
2012-05-03 06:18:56

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. This means just a few towering white fir, sugar pine and incense cedars per acre at the Yosemite site are disproportionately responsible for photosynthesis, converting carbon dioxide into plant tissue and sequestering that carbon in the forest, sometimes for centuries, according to James Lutz, a University of...

Ancient Forest In NY More Diverse Than Scientists Thought
2012-03-02 05:38:06

[ Watch the Video ] 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. Partially uncovered by quarry workers in 1870, the ancient forest beneath the tiny town of Gilboa, N.Y. has been of intense interest to paleobotanists since the 1920s. Dating back to the Devonian Period, researchers early on...

Future Of Sumatran Tigers Threatened By Human Disturbances
2012-03-01 04:52:51

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. The study, conducted by Virginia Tech and World Wildlife Fund (WWF), is the first of its kind to systematically investigate the use of different land cover types – not just forests but also plantation...

Team Finds Natural Reasons Behind Nitrogen-rich Forests
2012-01-19 04:29:24

Many tropical forests are extremely rich in nitrogen even when there are no farms or industries nearby, says Montana State University researcher Jack Brookshire. It's because of biological interactions that occur naturally in the forests, Brookshire and four colleagues said in a paper they published Jan. 15 in the online version of the journal Nature Geoscience. Disputing some long-held beliefs about high nitrogen levels in forests, Brookshire said pollution isn't always the reason...

Image 1 - Leaf Litter Ants Help Make The Case For Rainforest Conservation In Borneo
2011-10-20 11:00:26

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. Leaf litter ants are often used to measure the overall ecological health of an area because of the large number of species present and because the health of the leaf litter is a good indication of the...

A team of researchers from Singapore, Australia, Switzerland, the UK and the USA has carried out a comprehensive assessment to estimate the impact of disturbance and land conversion on biodiversity in tropical forests. In a recent study published in Nature, they found that primary forests — those least disturbed old-growth forests — sustain the highest levels of biodiversity and are vital to many tropical species. Rampant rates of logging and agricultural expansion have...

Certain research and education activities remain 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 Wind River Canopy Crane, located in a 500-year-old forest near Stevenson in southwest Washington, has been operated cooperatively by the University of Washington, the Forest Service's Pacific Northwest...

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
2013-04-02 11:17:47

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...
