– Imported firewood is a major pathway for invasive species
By Oregon Department of Agriculture

Buy local has a whole new meaning when it comes to protecting Oregon from invasive species this fall and winter. Consumers are urged not to purchase firewood from out-of-state and all the insects and diseases it might carry. Instead, buying local firewood can help keep invasive species from gaining a foothold in the Oregon environment.

“Firewood is a major pathway for moving invasive species, and that’s not a good thing,” says Dan Hilburn, administrator of the Oregon Department of Agriculture’s Plant Division and member of the Oregon Invasive Species Council (OISC). “The take home message to Oregonians is to buy their firewood locally and burn it locally.”

Whether it is used at a campground or at home, people are transporting firewood great distances these days, taking with them any bugs or diseases that might not be native to that area.

New nursery research projects at NORS-DUC

Pending California Department of Pesticide Regulation approval, the following five projects will soon be underway at the National Ornamentals Research Site at Dominican University of California (NORS-DUC). All projects have been funded through the fiscal year federal Farm Bill. For more information on the projects or the NORS-DUC program, contact Sibdas Ghosh at sibdas.ghosh@dominican.edu.

Sudden oak death: Plotting trail, testing leaves


A map plotting the path of destruction that the tree-strangling pathogen known as sudden oak death is taking through the Bay Area shows new infestations in and around neighborhoods throughout the region.

The effort to track the wily killer's movements is the result of a major effort to involve citizens in the battle against the mysterious pathogen, which has killed tens of thousands of oak trees from Big Sur to southern Oregon.

P. ramorum spread to Northern Ireland

Tree killing disease spreads to NI

A private woodland and two government-owned forests in Northern Ireland have been devastated by an outbreak of a killer disease.

It has become known as Sudden Oak Death, but it is really a fungal-like infection that kills Japanese larch trees.

Research on SOD at Fort Detrick

Fort Detrick USDA unit a quiet but important part of global food security

On opposite ends of Fort Detrick, overshadowed by the mammoth infectious disease laboratories that sit in between, are two sets of greenhouses belonging to the U.S. Department of Agriculture.
The diseases studied inside aren't as infamous as the anthrax and Ebola tested elsewhere at Fort Detrick, but the USDA research in the greenhouses saves plants vital to the farming, lumber and tourism industries.

An aggressive and unpredictable fungal pathogen is devastating larch plantations in Britain. Its remarkably broad host range, and the possibility of further geographical spread, give heightened cause for concern.
