Webinar: Transitioning Black Ash Wetlands to an EAB Infested Future

Tuesday, October 17 from noon to 1:00pm Emerald ash borer is just now beginning to extend into the near mono-specific black ash (Fraxinus nigra) wetlands of the western Great Lakes region. Loss of ash from these forests may have profound changes on ecosystem structure and function. I discuss a project located on the Chippewa National Forest that is designed to […]

Fall control for EAB

The risk status for emerald ash borer was changed yesterday to low activity. This is a great time of year to inspect your ash trees and prune or remove any branches, stumps, or trees. Forest landowners who have a stewardship plan for their ash stands may be preparing for a harvest to reduce the percentage of ash on their property. […]

Changing Ash Habitats and the Wildlife Impact

Fraxinus Fuss A little green bug has potential to cause quite a bother in Minnesota when it comes to our trees in the genus Fraxinus, or ash trees. This pest, the emerald ash borer (EAB), is an invasive insect from Asia. First discovered in Michigan in 2002, it has caused the death of millions of ash trees in the eastern […]

May 2016 webinar: EAB and woodland ash

Tuesday, May 17, 2016, noon – 1:00 p.m. With recent discoveries of emerald ash borer in and near Minnesota’s northwoods, foresters are getting more serious about silvicultural options as we face potential widespread ash mortality. Forest health specialist Bob Heyd has seen this loss first hand in Michigan and will share lessons from that experience. We’ll also hear from Andrew […]

Emerald ash borer risk status in Minnesota

Q: What is emerald ash borer? Emerald ash borer (EAB) is a non-native insect transported from Asia to the US and identified in Michigan in 2002. EAB feeds on the tissue of ash trees between the bark and sapwood and disrupting the nutrient and water flow of the tree, eventually killing the tree after several years of feeding in the trees. […]

September 2015 webinar: Hydrology of Black Ash Wetlands: Implications for management of the EAB threat

Tuesday, September 15, 2015, noon – 1:00 p.m. Hydrology of black ash wetlands is likely to be modified following EAB infestation, but the magnitude of alteration is not clear as we know relatively little about how these unique ecosystems function.  Findings from a large-scale experiment related to water table dynamics following manipulation of black ash stand composition will be presented and […]

Using citizen science to combat Emerald Ash Borer

Have you heard about Wasp Watchers? There’s been some media buzz lately, with stories in the Star Tribune and Post Bulletin highlighting the program kicking off this summer. Wasp Watchers uses the smoky winged beetle bandit wasp as an early detection tool for Emerald Ash Borer (EAB). Citizen scientists throughout Minnesota will be searching for and adopting wasp nesting sites in order to collect samples […]
