Old-Growth Forests Dying Off in U.S. West
Tree deaths have doubled, and global warming may be the cause, experts say THURSDAY, Jan. 22 (HealthDay News) -- Trees in old-growth forests in the Western United States are dying at twice the rate they were a few decades ago, and experts suspect regional warming is to blame. The re...Northern Forests Less Effective Than Tropical Forests in Reducing Global Warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought , according to a study appearing in this week's issue of Science. The study, which sheds light on the so-called missing carbon sink,...India to Protect Its Forests With the Aid of Austrian NGO
India, which is fast losing its forests to over-exploitation, will get help in protecting its green cover from an Austrian research organization which signed up the// country as a member this month. The International Institute for Applied Systems Analysis (IIASA), Austria - a non-governmental...Will The Tropical Forests Survive The Deforestation Scenario?
Tropical forests are slowly being removed from the face of the earth by the process of deforestation. This is done to satisfy the growing needs// of the human population. This has resulted in complete extinction of the forest species. Humans in rural settings contribute most to deforestation.

Human induced nitrogen deposition is indirectly "fertilizing" forests, increasing their growth and sequestering major amounts of carbon, a joint study by scientists from 10 universities in the US, Canada and Europe, has revealed.

The forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in coming years, a recent study concludes, if they are managed primarily for that purpose through timber harvest reductions and increased rotation ...Managing Douglas-fir forests for diversity
PORTLAND, Ore. May 8, 2009. Creating diverse forests for multiple uses is important to natural resource managers and landowners. A study conducted in southwestern Oregon provides forest managers with information that offers choices when managing land for a variety objectives that may include a hig...Cleaning the atmosphere of carbon: African forests out of balance
Tropical forests hold more living biomass than any other terrestrial ecosystem. A new report in the journal Nature by Lewis et al. shows that not only do trees in intact African tropical forests hold a lot of carbon, they hold more carbon now than they did 40 years ago--a hopeful sign that tropi...Wildfires result in loss of forests reserved by Northwest Forest Plan
PORTLAND, Ore. November 6, 2008. Although the Northwest Forest Plan (NWFP) significantly reduced cutting of old-growth forests on federal land, forests in the driest regions are now at greater risk of being lost to wildfire than to logging. A team of federal and university scientists recently comp...'Living fossil' tree contains genetic imprints of rain forests under climate change
ANN ARBOR, Mich.---A "living fossil" tree species is helping a University of Michigan researcher understand how tropical forests responded to past climate change and how they may react to global warming in the future. The research appears in the November issue of the journal Evolution . Sy...Old growth forests are valuable carbon sinks
CORVALLIS, Ore. 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. Howeve...Scientists point to forests for carbon storage solutions
COLUMBUS, Ohio Scientists who have determined how much carbon is stored annually in upper Midwest forests hope their findings will be used to accelerate global discussion about the strategy of managing forests to offset greenhouse gas emissions.

COLUMBUS, Ohio Wealthy nations willing to collectively spend about $1 billion annually could prevent the emission of roughly half a billion metric tons of carbon dioxide per year for the next 25 years, new research suggests. It would take about that much money to put an end to a tenth of the ...New report: Greatest value of forests is sustainable water supply
WASHINGTON, D.C. The forests of the future may need to be managed as much for a sustainable supply of clean water as any other goal, researchers say in a new federal report but even so, forest resources will offer no "quick fix" to the insatiable, often conflicting demands for this precious reso...Workshop assesses interactions between climate, forests and land use in the Amazon Basin
On February 25 and 26, over 50 scientists gathered for a two-day workshop in Manaus, Brazil, to discuss the current state of knowledge on the feedbacks between deforestation and climate in the Amazon and what research is required to avoid catastrophic change.

WEST LAFAYETTE, Ind. - Engineers have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. The carpetlike growth of nanotubes has been...Biodiversity threatened as forests become 'islands' of green, UW professor says
