There is a national effort to limit the spread and impact of EAB. A national plan, coordinated by the United States Department of Agriculture, Animal Plant Health Inspection Service, guides what federal, state and local officials must do to manage this insect.
Quarantine: Once EAB is confirmed in an area, the infested area must be quarantined. This means selected materials such as ash firewood, nursery stock and ash logs may not be moved out of the infested area. The Quarantine area is county wide and determined by state officials.
In Conjunction with the WDNR, the WI Dept of Agriculture, Trade and Consumer Protection (DATCP) is currently leading the efforts to detect, plan for and limit the chances of movement of EAB into and throughout Wisconsin. The WI DNR, together with DATCP and University of Wisconsin scientists, have been conducting detection surveys of areas deemed high risk for introduction of EAB. These organizations have been hosting conferences for municipal forestry staff to learn about EAB and how they will need to handle the quarantine plans in their own county or city.
Dane County Emerald Ash Borer and Wood Utilization Strategic Management Plan
With the emerald ash borer (EAB) already present in southeastern Wisconsin, Dane County is taking steps to prepare for this invasive beetle's arrival. With proactive preparation as its guiding philosophy, Dane County's EAB and Wood Utilization Strategic Management Plan will work to reduce the environmental impacts of the EAB within Dane County, mitigate the potential economic and social costs associated with control efforts and damage, and find ways to put wood formerly considered "waste" to positive and profitable use. Since an increased volume of wood residue will be among the EAB's most significant consequences, the plan also outlines various options for dealing with wood materialsâ€”from infestations as well as potential storm eventsâ€”in an economically and environmentally sound manner.
The City of Madison established an EAB Task Force in January of 2008. Even though EAB has not yet been found in Madison, education, planning and detection efforts are well underway.
In 2007, the Forestry Section began a Street Tree Inventory of terrace trees. The City of Madison is in the process of completing the Street Tree Inventory. At this time the street tree inventory is about 80% complete.
Disclaimer: The City of Madison is in the process of completing the street tree inventory. At this time the street tree inventory is about 80% complete. We have inventoried 19,923 (24.66%) ash trees, with another 2,000 ash street trees estimated to be added when inventory is complete with a total estimate of all species of Madison street trees of 95,000. However, tree inventories have not been conducted in city parks, greenways or on other municipal properties.
Each aldermanic district has its own EAB susceptible tree map. You will need to know what alder district you live in.
The street trees that are susceptible to EAB are indicated by red dots. Parts of the city have not had a street tree inventory conducted and they will be shaded on the map. However, we estimate that there is about an additional 2,000 ash street trees in these areas.
In 2013, the Forestry Section collected ash branches from street trees on a one mile grid basis. Forestry Staff peeled off the bark of the branches to search for EAB larvae. EAB was not found. In the winter of 2014, Forestry Staff will again conduct branch sampling, this time at the recommended grid of 0.6 of a mile. This is the only early detection tool available for finding low level EAB populations. This method is considered to be 80% effective of finding EAB in low level populations.
