Buprestidae Overview The goldspotted oak borer GSOB is a buprestid beetle which is native to oak forests of Southeastern Arizona, and a closely related species Agrilus coxalisalmost identical in appearance, is found in Central Mexico, and Northern Guatemala. SinceGSOB has contributed to the mortality of more than 80, trees over approximately 4, km2, and this infested area continues to increase as the GSOB population grows and spreads. In its native range, GSOB is not a pest.
Forest Service calculated the net sequestration of forests in the country to be million metric tons of carbon dioxide per year, or a quantity sizeable enough to offset emissions from 50 million vehicles in a year.
According to the U. Forest Servicemethods for improving carbon sequestration include avoiding deforestation, afforestation planting a forest where there was not a forest previouslyreforestation or the use of wood-based energy or products. One initiative announced by the USDA in the spring of will seek to improve carbon sequestration through farming and forestry practices.
The program, the Climate Smart Agriculture and Forestry Strategywill utilize public-private and voluntary partnerships to reduce greenhouse gases by million metric tons—or about two percent of net emissions—by through 10 identified building blocks.
Building blocks include expanding existing conservation programs for carbon storage, protecting privately owned forests, changing the stewardship of federal forests, promoting the use of wood in construction and planting urban forests.
As Emerald ash borer research paper below, many state policymakers are encouraging forest carbon sequestration initiatives through legislation. Harvested wood products HWPssuch as lumber and paper, constitute an additional carbon pool.
HWPs do not contribute to greenhouse gas emissions and do not continue to absorb carbon, however the majority of carbon previously stored in HWPs remains sequestered post-harvest.
While the specific volume of carbon stored in HWP is dependent on the type of wood and the final wood product, the Pinchot Institute for Conservation reports that 20—33 percent of above-ground carbon is captured in timber harvesting. Forest Service, found that HWP contributed an average of million metric tons of carbon dioxide sequestered per year between and For comparison, the same report states all forestlands stored million metric tons of carbon dioxide per year during the same period.
Threats to Forests Forests face multiple threats from invasive insects and diseases, wildfires, drought and urban development. These disturbances, all of which can be compounded by a changing climate, affect the amount of forestland and the rate of carbon sequestration and storage.
Invasive Species Invasive species can dramatically alter local ecosystems by decreasing biodiversity, out-competing and displacing native plants and animals, and threatening endangered species.
Invasive beetles, moths and other insects are destroying millions of trees across the country. Non-native insects have no predators in their new home and the trees have no natural defenses against them.
Top offenders include the Asian longhorned beetle, Asian citrus psyllid, brown marmorated stink bug, European gypsy moth and emerald ash borer. In addition to insects, diseases such as sudden oak deathchestnut blight and Dutch elm disease are also devastating forests.
The metallic green beetle native to Asia and Eastern Russia was discovered in Michigan in and has since spread to 25 states.
As its name suggests, the emerald ash borer infests ash trees, killing them within one to four years. A total of seven billion trees are at risk. The fund provides helps local governments, businesses and organizations purchase equipment to remove, dispose of and replace trees infested by the beetle.
State laws aimed at preventing new infestations often encourage the use of local firewood.
For example, Oregon enacted legislation in House Bill preventing individuals from transporting or selling firewood within the state, unless it was harvested in Oregon, Idaho or Washington and has been appropriately treated to remove any hitchhiking pests. Fire Each year wildfires consume thousands of acres of forest vegetation, including critical wildlife habitat and other forest resources.
Inmore than nine million acres burned across the United States, including five million acres in Alaska. For the first time in its history, fire suppression efforts consumed more than 50 percent of the U. Though healthy forests need fire to a certain extent, the frequency, size and intensity of wildfires has increased dramatically in the past decade, particularly in the West.A place where you can be with nature eye-to-eye!

The boxelder bug frequently becomes a nuisance pest around homes and buildings near plantings of the boxelder, Acer negundo. In heavily infested areas, they sometimes are associated with ash (Fraxinus spp.) and maple (Acer spp.). The very best hybrid sweetgums are being propagated to produce elite varieties, so that landowners will be able to plant trees that produce more biomass in a shorter time than the .
All ash trees in Hennepin County are threatened by the emerald ash borer, a destructive tree pest that attacks and kills ash trees.
To prevent the spread of the emerald ash borer, a quarantine is in place for Hennepin County and surrounding counties that prohibits hauling ash . Herms, McCullough, Smitley, Sadof, Cranshaw 3 E merald ash borer (Agrilus planipennisFairmaire), an invasive insect native to Asia, has killed untold millions of ash trees (Fraxinus species) in .
