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...

Forest Fire Predictor Model
2013-11-14 16:16:28

Brett Smith for redOrbit.com - Your Universe Online Just as forest fire season appear to be winding down, scientists at the National Center for Atmospheric Research (NCAR) and the University of Maryland have developed a new computer model that can constantly update daylong predictions during extensive blazes, according to a new report in an online issue of Geophysical Research Letters. “With this technique, we believe it’s possible to continually issue good forecasts throughout a...

Wildfire Smoke Poses Health Risks

redOrbit Staff & Wire Reports - Your Universe Online The increasing number of wildfires occurring throughout the US in recent summers has been sending carbon monoxide and other toxins into the atmosphere, causing respiratory issues among people living far from the affected areas, scientists with an environmental group warned late last week. According to Wendy Koch of USA Today, more than 200 million Americans (or two-thirds of the country’s population) lived in regions that had...

Fire Detection Satellite Designed By UC Berkeley Scientists

University of California, Berkeley Improved and cheaper sensors, faster analysis software make satellite feasible As firefighters emerge from another record wildfire season in the Western United States, University of California, Berkeley, scientists say it's time to give them a 21st century tool: a fire-spotting satellite. Such a satellite could view the Western states almost continuously, snapping pictures of the ground every few seconds in search of hot spots that could be newly...

Plant Mapping Project Highlights Where Rarest Species Thrive
2013-10-17 15:35:22

Lee Rannals for redOrbit.com - Your Universe Online An international group of researchers has created the most comprehensive map of rare plants to date. The new map, published in Ecology Letters, shows how climate stability plays a crucial role in the distribution of plants on Earth. It shows that rare species in the Americas are located in California, Mexico, the Caribbean islands, parts of the Andes mountains, the south of South America, and the region around Rio de Janeiro. "This...

Wildfires Change Climate Models
2013-08-30 13:45:15

Brett Smith for redOrbit.com - Your Universe Online While raging wildfires can consume property and even lives, the towering infernos could also be heavily influencing the forces of climate change. According to a new study from researchers at Michigan Technological University, forest fires emit massive quantities of two different kinds of particles – soot and tar balls. These particles remain in the atmosphere and should be taken into account when creating climate change models, the...
