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.
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.
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."
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.
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.
