Permanent Firewood Quarantines Continue to Expand



firewoodSince Emerald Ash Borer was first discovered in Michigan in 2002, trees have been being destroyed through the transportation of invasive insects in firewood. Many methods, including quarantines, have been implemented to slow the spread of EAB. The movement of firewood and other ash wood materials in infested areas is now being regulated by the infested states and federal government.

The Arkansas Decision

Last month in Little Rock, AR at the monthly meeting of the Arkansas Game and Fish Commission, commissioners permanently adopted a ban on the importation of firewood into the state’s wildlife management areas. The commission had previously approved an emergency ban on firewood; however, the permanent firewood ban goes into effect immediately.

What are Quarantined Items?

Generally speaking, it is illegal to move ash trees, ash logs, ash branches, ash wood chips, ash bark, and all hardwood firewood out of quarantined areas. Firewood is the only quarantined item that relates to all hardwood, whereas all other quarantined items are relative to ash only. Be sure to acquaint yourself with local rules and regulations when transporting wood from one jurisdiction to another.

How Far is too Far to Move Firewood?

Look for the closest convenient source of wood. A general rule of thumb is that 50 miles is too far, and 10 miles or less is best. In many states there are rules, regulations, and quarantines that clearly state boundaries.

Slow the Spread

One of the most important things we can do to protect trees is to stop moving invasive pests to new areas in firewood. Is your state under quarantine? Do you have questions specific to your area? Check out for all the information you need.

The Michigan Oak Wilt Crisis


Oak Wilt has been on the rise in Michigan and recently there has been such a spike that it has become an epidemic, especially on the west side of the state. It has spread across the state so anyone that has oak trees here should be aware and be monitoring for infection. The decimated numbers of oak trees in urban forests are bringing about a dramatic change in the area’s ecology, resulting in decreased air quality and hazardous clusters of standing dead trees. Arborjet’s Joe Aiken, the Great Lakes Regional Technical Manager, filled us in on the current crisis in Michigan.

Oak Wilt Awareness

“A few emails have gone out geared toward the forestry industry, but information hasn’t been targeted to the general public. I really want to get more information out to homeowners. One group in particular that I am concerned about are vacation cottage owners in Northern Michigan that may not be aware of the situation because they are not there enough. If you or a neighbor have a red oak in your landscape, you want to monitor Oak Wilt because if they have it the fungus can spread rapidly through root grafts.”

Don’t Move Firewood

The Michigan Department of Natural Resources released a bulletin on December 1, 2014 advising against the movement of firewood between state parks to help prevent the spread of Oak Wilt. Michigan DNR Parks and Recreation has been working the last several years to stop the spread of Oak Wilt at state parks.

Proper Pruning

“One important thing for the people of Michigan to understand is when to have an oak tree pruned. The fungus colonizes in the wound of the tree so when it is warm out you shouldn’t be cutting oak trees. The fungus is easily transported by beetles from infected wood to nearby wounded trees,” Aiken advised.


Oak Wilt is a lethal tree infection that cannot be cured and causes rapid death of untreated trees. Once the Red Oak trees become infected they can die anywhere within a month to a year. Aiken added, “People are shocked to be losing their oak trees faster than they lost their ash trees to Emerald Ash Borer. With the red oak it is that fast and that is why it is so important for people in Michigan to be aware of the signs and symptoms.”

Basic Identification

Initial symptoms of Oak Wilt are browning leaves, beginning at the leaf tip and moving downward toward the stem. As the disease progresses, limbs will die off. Fungal mats may develop under the bark, pushing the bark outwards causing deterioration.

Oak Wilt is a disease caused by an oak specific fungus (Ceratocystis fagacearum) that spreads through root grafts and by insects. The infection causes leaf discoloration, defoliation and death.

Red Oaks are particularly susceptible to Oak Wilt and often succumb quickly. White oaks are more tolerant of the infection as they do not form damaging fungal mats.

Be Pro-active & Get Information

Madison WI: Neighbors Determined to Save their Ash Trees


Earlier this week, Arborjet spoke with Linda Haglund-Lynch, a member of the Eastmorland Community Association in Madison, Wisconsin. She has been involved with the Green Ribbon Project’s effort to raise awareness about Emerald Ash Borer and all the ash trees that will be lost if left untreated. Currently there are nearly 300 green ribbons around the ash trees in east Madison parks. Here’s what Linda had to say:

Project Origins

“The original project started when they took down a few trees in Sherry Park. Several members of the Eastmorland Community Association including myself inquired why they were cut down because they were very large healthy ash trees. They told us the city has budgeted to protect many of the trees lining streets with Arborjet’s TREE-äge, however all city park ash trees are scheduled for removal due to lack of funding for treatment. They informed us of the Adopt a Tree program and we immediately started trying to get as many as possible adopted.

“We wanted to make sure that people understood the scope of the situation with the numerous ash trees in our parks. Some park trees will have to be cut down, but it will really make a difference if we treat as many as possible and that is our goal. The ribbon is a powerful visual aid when trying to imagine the immense impact.”

Preserving for Present for the Future

“Many people are really enthusiastic about treating our park’s trees. One couple donated to save a tree in Sherry Park because they have an eighteen month old son. She said that she ‘wanted to have shade in her son’s play area, as this is the park that he uses all of the time.’ Many people understand the impact this is going to make on the parks, not only the shade but the birds, air quality and the beauty of the park will be compromised. Even if the mature ashes are replaced with small trees it won’t be the same until they age for another 50-100 years.”

Educating the Community

“Many people are under-informed, so we are trying to educate the community about the treatment. We emphasize the reduced risk and efficacy of trunk injection. In upcoming weeks we will be consulting with experts that all supported treatment in their articles and reinforce the importance of treating as many ash as possible. Additionally, they believe long term treatment cost and frequency may go down once all untreated ash trees are removed. Once you have a large group of treated trees EAB will start to decline and it will become easier to keep them healthy.”

You Can Help

“The Parks division’s Adopt-a Park Tree program allows for residents to apply to adopt park ash trees. If the chosen tree is assessed as healthy and large enough to be treated, residents can pay for city-approved contractors to treat by injection. The ECA set up a general fund so people can donate any amount and all donations go toward treatment costs of park ash trees. In Jan 2015, the parks division will start cutting park ash trees more aggressively in known infested areas then move on to other east side parks. Only park ash trees applied for will be spared once removal commences in non-infested parks. If you’re interested in saving an ash tree, visit:

Customer Endorsement- Saved My Hemlock

New New growthSix months ago I noticed that the evergreen in my backyard was covered in small white powdery spots that I later identified as Hemlock Woolly Adelgid (HWA). I procrastinated with treatment until the pest progressed to where the tree’s appearance started to decline and I had little hope for its survival. I had to do something quickly.

I had heard about Arborjet, so I checked out the website and found a service provider in my area who came to evaluate and inject the tree. In the months following the treatment, the HWA is completely gone and there is a substantial amount of new growth. I’m very thankful that Arborjet treatment worked and saved my tree.

Here’s an actual photo of tree months after injection!

Fort Wayne, IN: Saving & Replanting Trees

Fort WayneAs Fort Wayne faces its 8th year of Emerald Ash Borer devastation, the Parks and Recreation has approved a new five-year plan called Shading Our City: Urban Forest Management Plan. The plan intends to provide a framework for ensuring that the trees and forests of Fort Wayne are appropriately cared for according to community goals. The plan is broken into four elements covering all aspects of managing an urban forest.

Maintenance and Protection

The maintenance and protection element establishes the framework to provide healthy and productive conditions for trees to prosper. The goals of maintenance are to provide safe and functioning public spaces that maximize the environmental, social, and economic benefits of trees. Fort Wayne has been maintaining and protecting existing trees with TREE-äge® Insecticide. The trunk injections have proven to be successful with approximately 97 percent of treated trees flourishing.

Monitoring and Documentation

Another element of the plan is monitoring and documenting the urban tree canopy. Tracking and examining changes to the canopy and recording all observations will provide the data necessary to manage all aspects of the urban forest. Keeping up to date tree inventories will allow the municipality to track the success of the process.

Sustainability and Management Goals

The final elements of the plan establish sustainability and management goals that will keep the parks and urban landscapes thriving for years to come. The sustainability portion will provide fiscally and environmentally for the urban canopy, allowing the community to benefit for future generations. The second portion sets goals for street and park trees for the next several years. These include reduction of pruning cycle, increasing plantings, adoption of tree risk assessment program, and development of an invasive species management plan within the parks.


Planting trees and diversifying the tree species throughout the city is a major component of the effort. This will help replace some of the 17,000 trees lost since EAB was discovered in Indiana in 2004. Since then, the parks department has replaced about 10,000 trees.

The planting of new trees in proper locations will help to grow in the canopy making the community better for the future. The parks departments hopes to partner with businesses, neighborhoods, and community volunteers to purchase and plant a variety of new trees for parks and public spaces. Efforts such as The Great Tree Canopy Comeback event held on Saturday November 1st helped to directly fund re-planting city trees that are being lost faster than they are being replanted.

The Great Tree Canopy Comeback in Indiana

Fort WayneIn 2001, the community landscape report provided by the city of Fort Wayne, Indiana discussed the need to replace the tree canopy in several parks and public spaces. That year, the Friends of the Parks held the inaugural Great Tree Canopy Comeback event. The event literally brings new life to the tree canopies of Fort Wayne and Allen County. Holly Hunter, chair of the event spoke with Arborjet about the importance of saving and planting community trees.

Successful Partnerships

“We created a partnership with the local park systems and other organizations that have coupled with us. We take care of the fundraising for the trees and they select the variety. We all work together to determine which parks are in need of planting to determine our plan. The final stage is recruiting volunteers for planting. Over the years we have been successful in achieving the goals in the Cultural Landscape report, and have consistently responded to the need in this community after drought, storms, Emerald Ash Borer, and the natural life span of healthy trees.”

This Weekend’s Event

“This Saturday, more than 270 trees will be planted throughout Allen County. We are anticipating nearly 300 volunteers planting trees throughout the eight parks. We can always use donations and we certainly need additional volunteers for the weekend.”

Ownership in the Community

“I got involved with the program because I am passionate about the parks and trees. We have families and groups that have been participating from the start and look forward to the event every year. It’s neat to see people take ownership of their parks and remember the trees they planted in previous years. We are teaching the community the proper way to plant a tree, which can be surprisingly tricky and potentially fatal to the tree if done incorrectly.”

The Arborjet Connection

“Arborjet’s TREE-äge product saved many mature trees in our community. Due to our large ash population, the municipality was limited to injecting trees in specific areas where the town felt they were critical to the landscape. We are thrilled to be able to preserve the health of so many trees and protect them from EAB.”

Learn From Experience

“People look at the park system when they are looking to move to an area. We have a great park system that is incredibly valuable to our community and we want to continue that. I hope that other communities suffering from EAB devastation will look to us and similar municipalities with successful management plans. We encourage everyone to identify and treat valuable trees before they are compromised and in need of replacement.”

Des Moines, Iowa Chooses to Save Ash Trees


Emerald Ash Borer was first detected in southeastern Michigan in 2002, and since then it has killed more than 50 million ash trees in over 20 infested states and provinces.

EAB infestations have been detected in 13 Iowa counties with the most recent occurring in Story County in August. EAB has yet to arrive in West Des Moines, but city officials are preparing for the inevitable. There are 52 million woodland ash trees and 3.1 million urban ash trees in the state, according to the Department of Natural Resources’ website.

Learning from Chicago’s Success

Chicago is among the almost 200 cities that have been using TREE-äge to effectively protect public ash trees from EAB.

Last month, Mayor Rahm Emanuel and the Department of Streets and Sanitation announced a 93 percent survival rate for ash trees inoculated in 2011 and 2012. “The Emerald Ash Borer treatment program is a common sense investment in Chicago’s parkway trees,” said Mayor Emanuel.

Chicago Commissioner Charles Williams said “The positive success rate in EAB retreatment is encouraging, and the Department looks forward to completing the remaining inoculations of all viable ash trees this fall.”

The Old and New Plans

The city’s initial management plan called for the removal of the entire inventory of 1,100 of ash trees over about a four-year period. These ash trees were to be removed “regardless of location, current condition or benefits provided.”

The West Des Moines City Council now plans to cover the cost of TREE-äge injections for healthy adult trees that meet the criteria and are located in the public right of way. “We’re saving the ones that will be around for a while,” Councilman Rick Messerschmidt said after the meeting.

Residents Care

Tony and Connie Powers joined other Des Moines residents and signed a “tree lovers” petition. They were pleased with the new approach that should give their ash trees prolonged life.

“We have such a beautiful canopy of ash trees,” said Tony Powers. “That’s one of the significant features of our street. Can you imagine if the city were to cut down all of our ash trees? It would just leave the neighborhood with a barren look.”

Arborjet for Your City

We have a responsibility for the health of our city’s trees and urban landscapes. It’s imperative that we protect valuable public trees, reduce liability, and manage costs for future generations.

“There are still some larger communities that have not put together a plan, and there are many communities that do not have a tree expert,” said Emma Hanigan, an urban forestry coordinator at the Iowa Department of Natural Resources.
