Dying Trees Set Stage For Erosion And Water Loss
2012-06-28 04:01:37

New research concludes that a one-two punch of drought and mountain pine beetle attacks are the primary forces that have killed more than 2.5 million acres of pinyon pine and juniper trees in the American Southwest during the past 15 years, setting the stage for further ecological disruption. The widespread dieback of these tree species is a special concern, scientists say, because they are some of the last trees that can hold together a fragile ecosystem, nourish other plant and animal...

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology. Kara Huff Hartz, Gannet Hallar and colleagues explain that...

Shortleaf pine-hardwood ecosystem restoration following insect outbreak Research by USDA Forest Service Southern Research Station (SRS) scientists shows that the impacts of recent outbreaks of southern pine beetle further degraded shortleaf pine-hardwood forest ecosystems in the southern Appalachian region. The authors suggest that cutting and burning these sites reduces heavy fuel loads, improves soil nutrient status, and opens the canopy for restoration of these shortleaf pine...

Periodic outbreaks of bark beetles can cause annual losses of millions of dollars and pose serious challenges for forest managers, and the suppression of outbreaks is particularly difficult and expensive. According to T. D. Schowalter, author of a new open-access article in the Journal of Integrated Pest Management called "Ecology and Management of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern Pine Forests," preventative measures are most effective in minimizing losses...

Warming temperatures appear to allow pine beetles to now breed twice a year Long thought to produce only one generation of tree-killing offspring annually, some populations of mountain pine beetles now produce two generations per year, dramatically increasing the potential for the bugs to kill lodgepole and ponderosa pine trees, University of Colorado Boulder researchers have found. Because of the extra annual generation of beetles, there could be up to 60 times as many beetles...

The southern pine beetle, Dendroctonus frontalis Zimmermann, is a chronic insect pest within pine forests in the southeastern United States. Under favorable environmental and host conditions, it is an aggressive, primary bark beetle capable of killing large acreages of pines. Its principal range stretches from east Texas and Oklahoma to the east coast and north to southern New Jersey. In "Implications of Population Phases on the Integrated Pest Management of the Southern Pine Beetle,...

Researchers see increase in snowpack under bare dead pine trees, earlier melt under dead trees with red needles A new University of Colorado Boulder study indicates the infestation of trees by mountain pine beetles in the high country across the West could potentially trigger earlier snowmelt and increase water yields from snowpack that accumulates beneath affected trees. Led by CU-Boulder geological sciences department doctoral student Evan Pugh, the study was undertaken near Grand Lake,...

The Walking Mountain Science Center selected Zehren & Associates and Mithun architect firms to design a four-building campus that would live up to its dedication to sustainability, environmental awareness and science education and uses a custom low-VOC water-borne wood stain developed by Sansin Corporation and Vintage Woods that is UV resistant, water repellant and rot resistant, allowing the beauty of the beetle kill Pine wood and its color variation to stand out. Avon, CO and Strathroy,...

Lodgepole Pine, Pinus contorta
2014-04-27 08:06:16

Lodgepole pine (Pinus contorta) is found in western North America in the upper mountains and subalpine regions of Colorado’s northern Rocky Mountains. This tree is considered to be invasive in New Zealand. This tree is also known as the shore pine, twisted pine, and contorta pine as well as black pine, scrub pine, and coast pine. The Lodgepole pine grows best between 8000 and 10,000 feet above sea level. They like to grow in well-drained, slightly acidic, sandy soils on gentle south...

Shortleaf Pine, Pinus echinata
2014-04-14 11:10:26

Shortleaf pine (Pinus echinata) is native to the southeastern United States. This tree is found in 22 states and has a range from 10 feet in elevation up to 3000 feet. The range includes southeastern New York and New Jersey west to Pennsylvania, southern Ohio, Kentucky, southwestern Illinois, and southern Missouri; south to eastern Oklahoma and eastern Texas; and east to northern Florida and northeast through the Atlantic Coast States to Delaware. This pine can grow in wetlands as well as in...
