With spring migration in full flight, a new report urges greater protection for an avian haven WASHINGTON, May 5, 2014 /PRNewswire-USNewswire/ -- It's been dubbed North America's bird nursery: the sprawling billion-plus-acre boreal forest that spans the continent from Alaska across Canada to Newfoundland and Labrador. http://photos.prnewswire.com/prnvar/20140502/83858 Each spring, an estimated 1 billion to 3 billion nesting birds make the long journey north to the boreal forest from wintering...

Climate Not The Only Factor Ushering In Change For Northern Forests
2014-04-21 11:45:00

USDA Forest Service In the most densely forested and most densely populated quadrant of the United States, forests reflect two centuries of human needs, values and practices. Disturbances associated with those needs, such as logging and clearing forests for agriculture and development, have set the stage for management issues of considerable concern today, a U.S. Forest Service study reports. The report – Five anthropogenic factors that will radically alter forest conditions and...

Young Tropical Forests Contribute Little To Tree-Biodiversity Conservation
2013-12-12 17:14:28

Smithsonian Tropical Research Institute A satellite image of a green swath of tropical forest does not tell the whole story. About half the world's tropical forests are relatively young. Unless protected, they are unlikely to last more than a human generation before falling to bulldozers and chainsaws. These ephemeral secondary forests may contribute little to tree-biodiversity conservation, according to a new report by scientists at the Smithsonian Tropical Research Institute in Panama....

As trees grow larger in even-aged stands, competition develops among them. Competition weakens trees, as they contend for soil moisture, nutrients, and sunlight. Competition also increases trees’ risk to bark beetles and diseases, and subsequently leads to a buildup of dead fuels. A recent study, led by Dr. Jianwei Zhang, research forester at the U.S. Forest Service’s Pacific Southwest Research Station, considered if the onset of this risk could be determined. The study, which appears in...

Trees Might Store More Carbon Than Thought
2013-10-03 07:03:41

DOE/Pacific Northwest National Laboratory Examining a long-lived forest, researchers have found that Black Spruce trees, which dominate the northern forests of North America, succumb about five years after being weakened by environmental stresses. Without rejuvenating fire, the dead trees aren't being replaced by new ones. The result will help researchers better understand how climate change affects the health of forests, and how forests affect the severity of climate change. The study...

Peru Cloud Forests Threatened
2013-09-12 12:13:07

Brett Smith for redOrbit.com - Your Universe Online According to a new study from Wake Forest University published by the journal PLOS ONE, a confluence of climate change and ecological factors could threaten Peru’s cloud forests, which are nestled along the eastern slopes of the Andes Mountains. Home to one third of Peru's mammal, bird and frog species, the cloud forests are renowned for their biodiversity and high elevation. At altitudes between 6,500 and 11,000 feet, they are a...

Fires Turn Boreal Forests Into Deciduous Woodlands
2013-07-23 09:27:55

April Flowers for redOrbit.com - Your Universe Online One of the most flammable high-altitude regions of the world, a 2,000-square-kilometer zone in the Yukon Flats of interior Alaska has seen dramatic increases in both the frequency and severity of fires in recent decades. A research team led by the University of Illinois reports the area has seen higher wildfire activity more recently than at any other time in the past 10,000 years. The findings were reported...

New research from the University of Guelph, published Tuesday in the journal Biodiversity and Conservation, says that allowing industrial extraction in a northern Ontario old-growth red pine forest – the largest remaining in the world – would significantly threaten biodiversity in Canada. The study says Wolf Lake Forest Reserve is a “scientifically irreplaceable system.” “Wolf Lake Forest deserves intensive study, monitoring and full protection from future development,” said...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Taiga
2013-04-19 18:21:46

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...
