Light Shed On Long-Term Effects Of Logging After Wildfire
Portland OR (SPX) Apr 10, 2007A new study on the effects of timber harvest following wildfire shows that the potential for a recently burned forest to reburn can be high with or without logging. Recently published in the journal, Forest Ecology and Management, the study demonstrates that the likelihood of a severe reburn is affected by the timing - not just the amount - of fuel accumulation after fire. The study examin ... more Invasive Grass May Impede Forest Regeneration 
Asheville NC (SPX) Apr 10, 2007The nonnative invasive grass Microstegium vimineum may hinder the regeneration of woody species in southern forests. Chris and Sonja Oswalt (Forest Service Southern Research Station) and Wayne Clatterbuck (University of Tennessee) set up experiments on a mixed-hardwood forest in southwest Tennessee to study the growth of the invasive grass under different levels of forest disturbance. Stud ... more Trees To Offset The Carbon Footprint 
Livermore CA (SPX) Apr 10, 2007How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. But the study concludes that planting new trees in certain parts of the planet may actually warm the Earth. ... more MORE HEADLINES

Slowly But Surely Burned Forest Lands Regenerate Naturally
Corvallis OR (SPX) Apr 09, 2007A new study of forest lands that burned in the 1990s in northern California and southwestern Oregon has concluded there is a "fair to excellent" chance that an adequate level of conifers will regenerate naturally, in sites that had no manual planting or other forest management. The research, to be published Wednesday in the Journal of Forestry by scientists from Oregon State University, examined the recovery of conifers on 35 plots that had burned in wildfires from 9 to 19 years ago, and generally found a high level of naturally-regenerating tree seedlings ... read more Boost In Rice Production To Avoid Food Shortages In Indonesia 
Jakarta, Indonesia (SPX) Apr 09, 2007Efforts by Indonesia to avoid food shortages by increasing its rice production have received an important boost with the signing of a new agreement to help the nation's millions of poor rice farmers with new technologies. Senior officials and scientists of the Indonesian Agency for Agricultural Research and Development (IAARD), and other agencies of the Indonesian Ministry of Agriculture, ... more Cable Laid For New Deep-Sea Observatory 
Moss Landing CA (SPX) Apr 09, 2007On April 1, 2007 researchers completed an important step in constructing the first deep-sea cabled observatory in the continental United States. In a multi-institution effort managed by the Monterey Bay Aquarium Research Institute (MBARI) and funded by the National Science Foundation, 52 kilometers (32 miles) of cable were laid along the seafloor of Monterey Bay. This undersea cable will provide ... more Earth Had Strong Magnetic Field Over Three Billion Years Ago 
Rochester NY (SPX) Apr 09, 2007Geophysicists at the University of Rochester have reported that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today. The findings, which are contrary to previous studies, suggest that even in its earliest stages the Earth was already well protected from the solar wind, which can strip away a planet's atmosphere and bathe its surface in lethal radiation ... more |
