Pests and Disease

Southern Pine Beetle Confirmed For the First Time in New York State

New York agencies have confirmed the presence of southern pine beetle (SPB) in three locations along the southern shore of Long Island. Personnel from multiple agencies worked together to verify the presence of this destructive beetle after the discovery of dead and dying pine trees in portions of the Wertheim National Wildlife Refuge, Connetquot River State Park and the Henry's Hollow Pine Barrens State Forest. This is the first detection of SPB in New York State.

Scientists are looking for emerald ash borer "survivor trees" in Michigan

Researchers with the USDA Forest Service are looking for ash trees that survived the attack of the emerald ash borer.

The invasive insect has been spreading across the Midwest and beyond since 2002, killing millions of ash trees in its wake. 

The Northern Research Station has launched a new online reporting tool. They want people in 10 counties in southeast Michigan and 7 counties in northwest Ohio to report the location of ash trees that have survived the infestation.

Michigan State Forester Fighting Oak Wilt with the USDA Forest Service

Emerald Ash Borer May be Infecting More Than Just Ash Trees

The emerald ash borer, which is destroying ash trees in a large swath of the nation, has apparently spread to a different tree, a researcher at Wright State University suspects.

Biology professor Don Cipollini, Ph.D., director of the Environmental Sciences Ph.D. Program, has found that the invasive green beetle has apparently begun to attack white fringetree.

Mountain Pine Beetle "Ate Themselves Out of House and Home"

The mountain pine beetle epidemic has been plaguing Colorado's pine forests for nearly two decades.

While the beetle is natural part of the eco-system, it began to spiral out of control in 1996. Scientists said that's when warmer temperatures and increasing drought conditions began to stress the trees, making them more susceptible to a beetle invasion. Then, the beetles went to lunch.

"People started seeing the effect of these mountain pine beetles on forests: needles that are dying, trees that are on their way to dying," said Chris Strebig of the U.S. Forest Service.

Fiscal Year 2013-2014 National Association of State Foresters Annual Report

Read the NASF Annual ReportThe National Association of State Foresters’ (NASF) FY 2013-2014 annual report is more than just an update on association accomplishments.  It is a testament to what engaged State Foresters, hard-working staff, and supportive partners did to help keep America’s

New York pool owners monitoring for invasive Asian long-horned beetles

Swimming pool owners can help scientists track the spread of invasive Asian long-horned beetles by checking their filters. The Department of Environmental Conservation invited pool owners to participate in its third annual Asian long-horned beetle survey, which is wrapping up today.

The beetles have killed hundreds of thousands of trees across the country. Particularly hard hit are maple trees in New York City, on Long Island, in New Jersey, in Chicago, in Worcester, Massachusetts and Clermont, Ohio.

Emerald Ash Borer Threatening Virginia's Forests

Virginia’s ash tree population coule be decimated in the next decade by the emerald ash borer (EAB).

EAB was first found in Virginia in 2003 in Fairfax County. The beetle, native to Asia, spread swiftly from Michigan along the interstate, carried in packing materials and firewood. The bug also spreads on its own, along rivers where ash trees are abundant.

Thousand Cankers Disease is Threatening Pennsylvania's Black Walnut Trees

Pennsylvania foresters are battling thousand cankers disease, which poses a threat to the state's $19 billion hardwoods industry.
"It absolutely has the potential to be disastrous," said Chris Miller, an arborist with the Davey Tree Expert company. "The long-term impact could be, eventually, no more black walnut. There are very few diseases that seem to affect them, so this is really a game-changer."

Invasive Feral Hogs Take Over Parts of Ohio

Invasive feral swine are chomping their way through the southeastern corner of Ohio.

"They're highly adaptable and very destructive," said Marne Titchenell, wildlife specialist with Ohio State University.

Feral swine can eat and trample crops, root up forests, outcompete native wildlife for food, and spread 30 diseases and 37 parasites. Yikes.

Feral swine cost the United States $1.5 billion a year in damage and control costs, according to a Ohio State University Extension fact sheet.
