Pests and Disease

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.

More than 441,000 Pine Beetle-Infested Trees Removed in South Dakota

More than 441,000 trees infested by mountain pine beetle have been cut down since South Dakota launched its Black Hills Forest Initiative three years ago.
"The governor's goal was to remove all beetle-infested trees in Custer State Park, and those efforts have paid off," State Forester Greg Josten told the Associated Press.

Invasive Weed Kudzu Can Grow Up to One Foot Per Day

Oh boy, is kudzu invasive.

The weed has been spotted in every county in Georgia, Alabama and North Carolina and is creeping northward into Ohio, Illinois and even jumping Lake Erie to establish a beachhead in Ontario, Canada.

The invasive plant costs property owners in the United States about $50 million per year in eradication, according to the Nature Conservancy.

Additional Species of Pine Bark Beetle Threatening Washington's Forests

If you're a landowner with pines in Washington state, there is now an additional species of pine bark beetle that may pose significant concern to your trees.

The California Fivespined Ips is a new pest on the scene and is showing up in the wildland-urban interface [PDF] of southern Washington state. The beetle favors the green, freshly broken branches of many species of pine including ponderosa, sugar, western white and lodgepole.

Emerald Ash Borer Wiping Out Kentucky Trees

Five years after the emerald ash borer arrived in Kentucky from the north where it killed more than 25 million trees, the full force of this Asian invader is being felt across the Bluegrass.
From Lexington to Louisville and north to Cincinnati, ash trees are being wiped out from rural landscapes, parks, leafy subdivisions and urban corridors.

Tree Pittsburgh Uses Goats To Clear Invasives from Dense Hillside

Environmental non-profit Tree Pittsburgh found a creative solution to clearing undergrowth on tricky terrain—goats.
Tree Pittsburgh hired consultant Brian Knox from Eco-Goats and rented more than 30 goats from local farm Goodness Grows to clear dense plant growth from a hillside near West Penn Park in Polish Hill. Tree Pittsburgh Tree Care and Restoration Coordinator Jake Milofsky said Tree Pittsburgh wanted to clear the area of invasive species so it could be regrown with more manageable vegetation, but the hill presented several problems.

Scientists Say Even Brutal Winters Aren't Stopping the Emerald Ash Borer

This past winter was the coldest Detroit had experienced in 36 years, but it did little to stop the invasive emerald ash borer.

“We didn’t find a single dead larva,” Deborah G. McCullough, professor of entomology and forestry at Michigan State, told the New York Times.

Asian Longhorned Beetle Harming 7 Billion Board Feet of Ohio's Maple Trees

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and the Ohio Department of Agriculture (ODA) has announced its 2014 plans for the state's Asian Longhorned Beetle infestation. The infestation was first discovered in 2012.

Ohio State University Extension Educator Dr. Curtis Young said the Asian Longhorn beetle is a borer and is as even greater concern then the Emerald Ash Borer.

University of Tennessee and Nature Conservancy Release Non-Native Insect and Disease Report

Fading Forests III is a new report released by the University of Tennessee and The Nature Conservancy compiling the latest data and analysis on the introduction, spread, and costs of non-native invasive tree pests and diseases.
Among the key findings:
  • In the last dozen years the emerald ash borer has spread from three states to 22; the Asian longhorned beetle has been detected at four additional sites; 28 new tree-killing pest species have been discovered.
