National Research Highlights
Cracking the Case of the Beech Leaf Disease Mystery
Year: 2020
Mysterious symptoms, referred to as beech leaf disease (BLD), have caused decline and mortality of American beech in Ohio since first observed in Lake County, OH, in 2012. By 2019 the disease spread to 13 other counties in Ohio, four other states, and Canada. A consortium of scientists from federal, state, and local government agencies in the United States and Canada, including the Northern Research Station (NRS), worked together to solve this mystery.
Scientists Join Forces to Save Ash Trees Facing Intercontinental Threats
Year: 2020
Ash trees across Europe are currently under attack by a fungal disease known as ash dieback disease while in the United States the emerald ash borer is killing ash trees at an unprecedented rate. An international team of scientists have worked for several years to find genes that are responsible for pest and pathogen resistance in trees.
Finding beech bark disease resistant American beech trees: It’s in the genes!
Year: 2017
A Forest Service scientist and her collaborators have identified genetic markers that may help accelerate breeding and production of American beech trees with resistance to beech bark disease, a disease that has spread throughout New England, continuing as far south as Tennessee and as far west as Wisconsin, causing significant mortality.
The Key to Rescuing Green Ash from Emerald Ash Borer is in the Genes
Year: 2016
Hundreds of genes in lingering ash trees have been identified that may help researchers understand the defense responses they use to defend themselves against emerald ash borer (EAB). Lingering ash and the genes they possess that help them combat EAB hold the key to saving green ash from extinction.
Green Ash Trees That Survive Beetle Infestation Pass on Their Resistance Through Propagation and Planting
Year: 2015
Among the tens of millions of trees killed by the emerald ash borer (EAB), researchers have found a small number of trees that survived their assault. Tests show that these surviving ash trees are more resistant to EAB than their counterparts. Breeding these select trees may produce trees with an even greater ability to survive EAB infestation and will provide seedlings to restore ash in areas destroyed by EAB.
Researchers From the U.S. Forest Service and the United Kingdom Join Forces To Save Ash Trees Facing Intercontinental Threats
Year: 2014
Ash trees across Europe are currently under attack by a fungal disease known as ash dieback disease, while here in the United States, they are being killed by the emerald ash borer at an unprecedented rate. In today's global economy there is risk that these ash menaces could cross the Atlantic Ocean and become a dual threat, causing the complete devastation of ash resources on both continents. Forest Service researchers are part of an international team that was recently awarded over 1.2 million dollars by the United Kingdom's Tree Health and Biosecurity Initiative to pioneer the application of a new method for finding genes that are responsible for pest and pathogen resistance in trees.
