HARRISBURG, Pa., March 14, 2013 /PRNewswire-USNewswire/ -- Governor Tom Corbett has proclaimed March 17-23 as Wildfire Prevention Week in Pennsylvania, noting warming temperatures and drying March winds have combined to increase fire dangers across Pennsylvania's forests and brush lands. "Last spring brought many brush and woodlands fires, showing us how quickly our wealth of forest resources can be endangered," Corbett said. "People cause 98 percent of wildfires; a mere spark by a careless...

Bats Undisturbed By Forest Fires
2013-03-08 09:07:56

Alan McStravick for redOrbit.com - Your Universe Online Forest fires are responsible for laying waste to entire ecosystems. As the flames rush through, animals attempt to make their escape, seeking shelter in less incendiary locales. Charred remains of trees and ground cover are completely unsuitable for sustaining the life of the animals that once called the area home. However, a new study led by bat ecologist Winifred Frick of the University of California, Santa Cruz (UCSC) reports the...

161-Year Study Shows Warmer World Causes Earlier Spring Flowering
2013-01-17 09:10:44

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from three universities have found that record temperatures in 2010 and 2012 resulted in the earliest spring flowering season in the eastern United States in more than 160 years. Using the phenological records of two iconic American naturalists, Henry David Thoreau and Aldo Leopold, scientists have shown that some springtime bloomers have appeared as much as a month earlier in response to the warming climate. This study...

Invasive Grass May Be Contributing To Extreme Wildfires

April Flowers for redOrbit.com - Your Universe Online An international team of scientists comprised of members from Penn State, UMass Amherst, UC Santa Barbara (UCSB) and University College London has revealed that an invasive grass species may be one reason that fires are bigger and more frequent in certain regions of the western U.S. Using satellite imagery, the team identified cheatgrass — a plant species accidentally introduced by western settlers during the 1800s...

NASA Says More Wildfires By 2050
2012-12-04 19:40:53

Michael Harper for redOrbit.com — Your Universe Online 2012 has been a bad year for wildfires in the US. According to data collected by NASA, some 6.17 million acres (2.5 hectares) have been consumed by wildfire this year alone. While this is just short of the record set last year of 7.90 million acres, (3.2 hectares) it´s larger than the amount of burned land in 12 of the last 15 years that scientists have been keeping tabs on wildfires. If some NASA climate models hold...

WASHINGTON, Dec. 4, 2012 /PRNewswire-USNewswire/ -- Scientists using NASA satellite data and climate models have projected drier conditions likely will cause increased fire activity across the United States in coming decades. Other findings about U.S. wildfires, including their amount of carbon emissions and how the length and strength of fire seasons are expected to change under future climate conditions, were also presented Tuesday at the annual meeting of the American Geophysical Union in...

Wildfires - Economic And Social Impacts
2012-09-16 05:57:54

April Flowers for redOrbit.com - Your Universe Online By the middle of August, nearly 7 million acres have burned in wildfires in the U.S. making this a record-breaking year for wildfire destruction. As of yesterday, the National Interagency Fire Center puts that number at 8,392,209 acres since January 1, 2012. This acreage comes from 712 large fires that have been contained so far this year. How does this kind of natural disaster affect the surrounding communities? Large wildfires,...

Brett Smith for redOrbit.com — Your Universe Online Human activities and disturbances can put a significant amount of stress on local environments and a new research review has shown that the functional diversity in arid, desert environments can be affected by the hand of man. According the report published in the Journal of Arid Environments, mammalian communities living in dry ecosystems are "drastically changing" as a result of human activities. "We report for the first...

Forest succession helps rare plants and animals Forests hammered by windstorms, avalanches and wildfires may appear blighted, but a Washington State University researcher says such disturbances can be key to maximizing an area's biological diversity. In fact, says Mark Swanson, land managers can alter their practices to enhance such diversity, creating areas with a wide variety of species, including rare and endangered plants and animals. "The 1980 eruption of Mt. St. Helens, for...

Logging Vital To Sustainability Of Ecosystem
2012-07-25 15:02:12

Brett Smith for redOrbit.com - Your Universe Online According to researchers from Oregon State University and Michigan State University, active forest management will help reduce the chances of a devastating, habitat-destroying wildfire. While targeted logging, tree thinning, and other fuel reduction activities might be a short term detriment to forested habitats of the Western U.S., they are vital to maintaining the long-term sustainability of this ecosystem, said the team´s...
