What’s the orange goo on that tree?!
Should I fight or should I flee?
I bet forest health staff can ID!
The spore-producing, slimy, orange gall caused by cedar apple rust fungus.

Many people know that invasive species are a concern in Wisconsin’s natural communities both on land and in water. But fewer people are aware that invasive species are not a new threat and that over time, we have developed strategies to reduce their spread and limit their damage to a tolerable level.
As soon as people from other continents started arriving in Wisconsin, so did the non-native plants, insects and microorganisms that came with them. Most of these non-native species are either beneficial or cause no harm, including well-known examples like honeybees, daffodils and even the bacteria used in cheese production. In contrast, the non-native species that damage native and domestic plants are known as invasive species, and over the years people have developed policies and practices to limit their impacts to native plant communities.

Emerald ash borer (EAB) was first identified in Wisconsin in 2008, although it was likely present in the state for a few years prior to detection. Since EAB doesn’t travel far on its own, some experts think it was unknowingly brought into the state on infested firewood, which is a common introduction pathway for many insects and diseases. The Wisconsin DNR Firewood page has more info on firewood and the insects and diseases that can travel on it.
Since its arrival in Wisconsin, EAB has steadily killed ash trees wherever it has been found. As of the writing of this article, there has been much more ash tree mortality in the southern half of Wisconsin than the northern half of the state where known EAB infestations are still widely scattered.

Wisconsin Community Tree Management Institute (CTMI) is a unique training experience designed for municipal staff with tree management responsibilities but without a strong background in urban forestry. The program is ideal for staff who spend just part of their time dealing with trees. Conversely, those with a background in urban forestry but new to management, will also find it useful. CTMI consists of approximately 38 instruction hours and requires students to complete an out-of-classroom project.
If you’re interested in applying, don’t wait – the 2020/21 class is filling quickly! The application deadline is June 12, 2020. See “How to Apply for CTMI” near the end of this article for instructions.

The history of the Wisconsin DNR Urban Forestry program is closely tied to the history of urban forestry in the United States. Although the term ‘urban forestry’ did not come into use until 1965, the concept of an integrated approach to the management of the urban forest ecosystem began to take shape as early as the 1930s. The devastation caused by diseases such Dutch elm disease, phloem necrosis, and oak wilt was a driving force in the development of the field of urban forestry. The term ‘urban forestry’ was first used in 1965 at the University of Toronto to describe a graduate student’s research on the successes and failures of municipal tree planting projects in Toronto. The term was quickly adopted in the United States, where urban forestry had already begun to grow into a national movement. (Source: Mark Johnston, “A Brief History of Urban Forestry in the United States,” Arboricultural Journal 1996, Vol. 20, pp. 257-278.)

The Urban Forestry Team provides guidance, training, information, funding and professional connection opportunities to municipal foresters and other professionals to achieve sustainable urban forestry management. In a (hickory) nutshell, our work falls into the following five categories:

“What is it about this place?” I wondered. “Why does this city feel so harsh, so disheartening?”
Two hours earlier I had stepped off a train in Patna, India, and I’d been stuck in a massive traffic jam ever since. Honking cars, motorcycles, buses, bicycles, rickshaws, and livestock hemmed me in, but after nearly two months in India, this was nothing new.
Rup, my husband at the time (we are now divorced) is from Calcutta, and I’d grown to love his hometown. Despite the massive cultural differences and sheer size of the city (population: 14 million), I’d warmed up to the place immediately. Calcutta felt welcoming from the moment I arrived; Patna did not. After only two hours in Patna, my nerves were frazzled, I had a headache, and I just wanted to escape.

Forest Action Plan meeting, September 2019
We’re glad you asked! The Wisconsin Urban Forestry Council is an advisory committee to the Wisconsin DNR Division of Forestry, currently comprised of 29 members appointed by the Secretary of the WDNR. Members represent the diverse groups and interests that impact our state’s urban and community forests, including representatives from professional organizations, private business owners, educators, green industry employees, nonprofit/service organizations, governmental agencies, municipalities of various sizes, utilities, concerned and active citizens and trade organizations throughout the state. The Council addresses strategies to help the WDNR implement, monitor, and revise the state’s urban forestry initiatives and to lend support to activities that further the understanding, appreciation and practice of urban forestry in Wisconsin. Members strive to aid all entities involved in urban forestry matters and to help coordinate activities to avoid duplication, inefficiency and conflict. The Council addresses a diversity of local, state, and national issues that can affect Wisconsin’s urban forests.

Since 1976, Tree City USA has been a catalyst for community tree care and a powerful force for promoting urban forestry. This program, sponsored by the Arbor Day Foundation (ADF) and administered in Wisconsin by the DNR, provides communities with a tangible goal and national recognition for their community forestry efforts. Today, over 3,400 communities fly Tree City USA flags over areas that house more than 143 million Americans. Wisconsin has over 190 Tree City USAs, ranking it second in the nation!
At the heart of the Tree City USA program are four basic requirements. The community must have: a tree board or department, an annual community forestry program backed by an expenditure of at least $2 per capita for trees and tree care, an annual Arbor Day proclamation and observance, and a tree care ordinance. In addition, communities that have achieved Tree City USA certification can strive for a growth award that recognizes effort over and above the four standards. Typically around 25 Wisconsin communities achieve this commendation each year.
