Silvicultural Recommendations for Ash
- Emerald Ash Borer Planning Simulator (EAB-PLANS®) - Beta Version
This program was developed to assist decision-makers in managing ash trees in urban and community forests challenged by EAB.
- EAB Cost Calculator - Beta Version
This version is driven by an EAB invasion wave model that lets you modify your treatment strategy after the initial wave of EAB has passed. It can produce estimates of forests that contain up to 4,000 ash trees.
- Factors affecting the survival of ash (Fraxinus spp.) trees infested by emerald ash borer (Agrilus planipennis)
2012 - Kathleen S. Knight, John P. Brown and Robert P. Long
The article is on the survival analysis of ash trees in Ohio. According to Kathleen Knight, the main take-home message was that ash trees actually died slightly faster in stands with lower densities of ash, the opposite of what the authors thought would happen. This is just the speed of mortality, not the % mortality (almost all the ash trees die eventually no matter what).

Chosen for a 2012 Notable Documents Award from the National Conference of State Legislatures (NCSL) for public policy, recognizing the publication as innovative in providing substantive information on contemporary issues of interest.
- Ash Silvicultural Prescription Handout (PDF, 2.3MB)
Michigan DNR - 2011 Great Lakes Restoration Initiative Grant
As the emerald ash borer (EAB) outbreak spreads through various Michigan Counties, landowners are advised to prepare by working with forestry professionals to obtain a forest management plan that prescribes harvest practices designed to reduce but not eliminate the ash component of their upland hardwood stands.
- Ash Management: Emerald Ash Borer
Michigan DNR - Forest Resources Division
As stewards of Michigan's ash resources, a goal is to reduce the vulnerability of our forest resources to the Emerald Ash Borer (EAB). The goal is not to eliminate ash from the forest, but to create a more diverse forest resource that is resistant to catastrophic changes affecting a single species or genera. Generally, the recommendation is to reduce the ash component of forest stands to a maximum10% of total stand basal area, and to promote tree species diversity. Vigorous pole size and smaller ash should be targeted for retention. Removing one large ash has a much greater effect on reducing EAB population potential than does removing many saplings or a few pole size trees. The objective is to create a stand that will maintain a minimum or greater basal area, in the event that all ash is eventually lost to EAB.
