Latest Old-growth forest Stories

A Smoky Mountain forest's woodland herb population has shown that climate may play a role in how forest understories recover from logging, according to Purdue University research. Despite heavy logging in portions of the forest nearly 80 years ago, the distribution of trillium plants on the secondary forest floor was similar to that of undisturbed areas. Michael Jenkins, a Purdue assistant professor of forestry and natural resources, said that contrasts with a study by other researchers of an...

Ad asks for rainforest's protection under national roadless rule WASHINGTON, Oct. 22 /PRNewswire-USNewswire/ -- The Pew Environment Group and 10 other conservation organizations called on Agriculture Secretary Tom Vilsack today to stop two controversial timber sales in roadless areas of Southeast Alaska's Tongass National Forest, one of the last intact temperate rainforests in the world. The groups asked Vilsack to honor President Barack Obama's commitment to uphold the 2001 Roadless...

Logged rainforests can support as much plant, animal and insect life as virgin forest within 15 years if properly managed, research at the University of Leeds has found. Because trees in tropical climates soak up large amounts of carbon dioxide, restoring logged forest through planting new trees could also be used in carbon trading, according to Dr David Edwards, from University's Faculty of Biological Sciences. Dr Edwards is calling for the inclusion of biodiversity-friendly strategies in...

Researchers from a variety of agencies and universities in the United States and Canada reported Thursday that trees throughout western North America are dying at twice the rate of 30 years ago. They say rising temperatures are the likely cause. These weaker and thinner forests will become more vulnerable to wildfires and may absorb less carbon dioxide, accelerating global warming, they say. The researchers studied trees in old-growth forests for more than five decades in order to document...

By Fred O. Williams Gov. David A. Paterson has enacted a law named for Buffalo-area environmentalist Bruce Kershner that protects old-growth forests, a cause that Kershner championed before his death last year. The Bruce S. Kershner Heritage Tree Preservation and Protection Act protects forests on state land that are more than 180 years old, adding them to lands in the state Nature and Historical Preserve. A proposal to extend the protection on private land by giving tax credits to...

Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries. However, these old growth forests around the world are not protected by international treaties and have been considered of no significance in the national "carbon budgets" as outlined in the Kyoto Protocol. That perspective was...

By Linda A Moore After only a few steps into the old-growth forest at Overton Park, Tom Heineke stops at a tulip poplar. It's old, possibly 100 to 175 years. But he can't be sure without further study. Moving deeper into the forest, where it's at least 10 degrees cooler, he points to other plants: Virginia knotweed, sea oats, and of course, poison ivy. For the next year Heineke will be spending lots of time in the 150-acre forest. He's been hired by the Memphis Park Services...

Researchers from the US and the UK have found a fossil forest in the coal mines of Illinois. The team reported a similar discovery last year, but has recently found five other examples. The petrified vegetation is visible in the mine ceilings covering thousands of hectares. Dr. Howard Falcon-Lang believes they are among the first forests to evolve on Earth. "Theses are the largest fossil forests found anywhere in the world at any point in geological time," Dr. Falcon-Lang said. "It is quite...

BIODIVERSITY is the variety of life on Earth - the whole range of plants, animals and fungi and the places in which they live. Biodiversity is vital to us all and provides many of life's essentials we take for granted: It provides our food; It regulates the Earth's atmosphere and provides us with oxygen; It is an important source of medicinal drugs and the open spaces where we get exercise and relaxation; The raw materials on which our economy is based and acts as a draw for...

Allegheny National Forest
2013-10-30 09:24:27

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...
