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.
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.
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.
Cogongrass (Imperata cylindrica) is a perennial grass that’s causing huge problems in the Gulf Coast and other regions of the South where temperatures don’t get cold enough to limit its growth. This weed invades forests, rights-of-way, and agricultural fields, literally taking over the landscape and altering ecosystems. Cogongrass varies widely in appearance, suggesting that there may be wide genetic variability within the species.
It turns out the chemical normally used to treat gout in humans is extremely effective in halting the spread of the disease known as citrus greening.
The Asian citrus psyllid appeared in Florida in 1998 and carries a bacterium that causes trees to produce bitter, misshapen, inedible fruit. The disease caused by the bacterium has infected as much as 70 percent of Florida's citrus over the past few years.
