How are communities handling EAB across Wisconsin?

The Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP) has recently issued a statewide quarantine for emerald ash borer (EAB), regulating the pest in Wisconsin. Since the menace has already affected 48 of Wisconsin’s 72 counties, many municipalities have been acting on EAB management plans they set into place, including the City of Racine and Ozaukee county have been managing the pest.

A statewide quarantine of the invasive insect emerald ash borer (EAB) will go into effect on March 30, 2018. Previously, individual counties were quarantined when EAB was confirmed within each’s borders. Since EAB has been found in 48 of 72 Wisconsin counties, officials have determined that statewide regulation of the devastating ash tree pest is warranted.

Movement of ash wood, untreated ash products and hardwood firewood of any type to areas outside of Wisconsin will continue to be regulated by USDA’s Animal and Plant Health Inspection Service, Plant Protection and Quarantine. (APHIS PPQ).

Within the state, Wisconsin businesses and members of the public will be able to freely move ash wood, ash products, and hardwood firewood to or from any Wisconsin county. Firewood restrictions will remain in effect on state and federal lands.

Items affected by the statewide EAB quarantine include ash wood with bark attached, larger ash wood chips, and hardwood firewood of any kind. County-by-county quarantines for gypsy moth, another invasive forest pest, remain in effect.

The move to a statewide quarantine does not mean that the state has given up on managing EAB; it is simply a shift in strategy as EAB continues its slow spread through the state. The Wisconsin DNR will continue releasing tiny, stingless wasps -natural enemies of EAB – at appropriate sites, which it has done since 2011. The DNR also continues participation in silvicultural trials in which different ash management strategies are being tested.

Most importantly, campers, tourists, and other members of the public are strongly encouraged to continue taking care when moving firewood within the state. “The actions taken by the Wisconsin public during the last few years have significantly slowed the spread of emerald ash borer and other invasive forest pests in the state,” said Wisconsin DNR EAB program manager Andrea Diss-Torrance. “We can continue to protect the numerous areas within our state that are not yet infested – including those in our own backyards – from tree-killing pests and diseases by following precautions.” Public members should continue to obtain firewood near campgrounds or cabins where they intend to burn it, or buy firewood that bears the DATCP-certified mark, meaning it has been properly seasoned or heat-treated to kill pests.

Emerald ash borer is native to China and probably entered the United States on packing material, showing up first in Michigan in 2002. It was first found in eastern Wisconsin in 2008.

Arbor Day: Show your appreciation

“When we see land as a community to which we belong, we may begin to use it with love and respect.” Aldo Leopold spoke these words many years ago, but they still ring true today. We all belong to a community, built around the people and the places we love and feel connected to, including trees and the land. Trees help shape communities and create sentimental landmarks that connect people and places. Consider the large elm that may hold a family tire swing, or the oak that made the perfect place for a secret club house, perhaps it’s under a crabapple tree that a couple shared their first kiss, trees becomes fixtures in our lives, bookmarks for the moments we relish.

The Urban Forestry program’s recently released Urban Tree Canopy data shows the extent of tree and shrub cover across every Wisconsin municipality and urban area. The City of New Berlin in southeast Wisconsin offers a glimpse into the kind of information you could derive from the canopy data. Continue reading “A Glimpse into New Berlin’s Tree Canopy”

Community Tree Management Institute: Building on a solid foundation

By Olivia Witthun, Urban Forestry Coordinator

CTMI students learningThe second of three sessions for Wisconsin’s Community Tree Management Institute (CTMI) was held February 6-7, 2018 in Green Lake. Through hands-on training and exercises, twenty-six students from across the state learned how to identify community forestry management needs and get the work done. Topics included: inventories, management plans, urban and community forestry operations (planting, pruning and removal), natural areas, tree biology, hardscape conflicts, soils, risk tree management and tree emergencies. Instructors for session II included: municipal forestry staff, university staff, consultants and DNR staff. The variety of instructors, their perspectives and interactive components are meant to appeal to all learning styles.
