Homeowners in Wisconsin feel the top 5 most important benefits provided by the trees in their yard are:
2) Shade and cooling
3) Improved air quality
4) Privacy, and
5) Making their neighborhood a better place to live
This list of homeowners’ perceived benefits from their trees is just one valuable insight gathered from the 2017 Wisconsin Urban Landowner Survey. More than 1,700 landowners responded to the survey from Green Bay, Madison, Milwaukee and Wausau, providing insights about their attitudes around tree care, their concerns about tree risks, and their tree care behaviors such as pruning and planting. Continue reading “Insights from the Wisconsin Urban Landowner Survey inform tree care outreach”
For many years the Urban and Community Forestry Program has maintained the Urban Forestry Consultants Directory, a document containing contact information and services provided by consultants who have made themselves known to DNR. Each May, we ask those listed to review their information and submit any necessary updates. We also welcome new submittals at this time, and throughout the year!

Jay Weiss created the Cambridge Tree Project to supply affordable and interesting trees and shrubs to homeowners to help fund landscaping in Cambridge and Rockdale schools, street and parks. The program was founded over ten years ago with a couple of simple goals: (1) add 1,000 living trees to Cambridge Village forest by 2020, and (2) increase species diversity of the community forest. Cambridge is working towards these goals by consistently offering a variety of tree species for purchase. The trees are available to anyone, regardless of where they live, but the trees must be purchased at the spring sale. Continue reading “Providing affordable trees to homeowners in Cambridge”
Planning Boosts Forest Health and Management
From the kitchen table to the boardroom table, the USDA brings people together across the nation for: healthier food, natural resources and people; a stronger agricultural industry; and economic growth, jobs and innovation.
Each Friday, meet those farmers, producers and landowners through their #Fridaysonthefarm stories. Visit local farms, ranches, forests and resource areas where USDA customers and partners do right and feed everyone.

Recently, I came across a beautiful, full evergreen. After a while, I realized I had planted this gorgeous monument when I was five years old, as part of a community project and Arbor Day celebration.
Communities across the state are reaching out to their citizens and encouraging them to plant trees in their own yards, greening the community with both yard and street trees. The Village of Bayside and the Village of Greenfield are accomplishing this through “Adopt-A-Tree” programs and species lists.

In a few weeks, gypsy moth egg masses will begin hatching in Wisconsin. Property owners interested in reducing gypsy moth populations should consider oiling or removing reachable egg masses well before the hatch begins. Horticultural oils that suffocate the eggs are available at many garden centers and large retailers. In general, these are applied when temperatures are above 40oF and freezing is not imminent. When physically removing egg masses, scrape them into a can of soapy water and then let them soak for a few days before discarding in the trash in order to kill the eggs. Additional management options for homeowners and woodlot owners are available at the Wisconsin gypsy moth website.
Property owners looking to hire a business to do insecticide treatments this spring should contact them soon. A list of certified arborists is available on the Wisconsin Arborist Association website. Additional businesses offering insecticide treatments may be found in the phone book under ‘Tree Service.’ Homeowners can also purchase insecticides, some of which are applied as soil drenches, at garden centers and large retailers. For larger areas, a list of for-hire aerial applicators is available on the Wisconsin gypsy moth website.
Although this winter’s cold temperatures in late December and early January most likely did not cause heavy egg mortality, the cold period will still help reduce gypsy moth populations this summer. According to the U.S. Forest Service, temperatures of -20°F lasting from 48 to 72 hours can kill exposed eggs. Eggs that are laid higher up on the bark of trees suffer higher mortality than those located near the ground because snow insulates the eggs from cold temperatures. Fluctuating spring temperatures can also cause heavy egg mortality.
2018 suppression spraying:
Dane County will be the only participant in the DNR gypsy moth suppression program in 2018. Aerial spraying will occur in mid- to late May at seven sites in Madison and one site in Sun Prairie. A total of 485 acres will be sprayed with a bacterial insecticide that affects only small caterpillars. Maps of the sites are available on the Wisconsin gypsy moth website.
Slow-The-Spread treatments announced:
The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) announced its planned 2018 Slow-The-Spread (STS) gypsy moth treatments in western counties. About 90,000 acres are scheduled for treatment at 36 sites in 14 counties, using low-flying airplanes. Treatments will begin in May and continue through late July or early August, using either bacterial insecticide or pheromones which cause mating disruption.
Counties scheduled to receive aerial treatments are: Barron (3 sites covering 2,736 acres); Bayfield (1 site, 787 acres); Buffalo (6 sites, 11,754 acres); Burnett (2 sites, 4,529 acres); Chippewa (4 sites, 12,794 acres); Crawford (4 sites, 5,971 acres); Douglas (1 site, 789 acres); Dunn (5 sites, 43,986 acres); Eau Claire (1 site, 674 acres); Grant (1 site, 497 acres); Green (1 site, 392 acres); Lafayette (2 sites, 527 acres); Rusk (1 site, 463 acres); and Vernon (3 sites, 3,785 acres).
More information on STS treatments may be found online at the DATCP Gypsy Moth website.

Wisconsin homeowners with healthy, valuable ash trees should consider treating the trees with insecticides this spring to protect against emerald ash borer (EAB). The pest is currently the most damaging threat to trees in the state, killing more than 99 percent of the ash trees it infests.
Woodpecker damage during the winter is often the first visible sign that an ash tree is infested, so it is important to examine your ash trees during cold months when leaves are absent. Now is a good time to consider protection with insecticides: insecticide treatments are usually applied between mid-April and mid-May once leaves begin to return. Treatments on already-infested ash trees are more likely to be successful if the trees exhibit only low or moderate levels of woodpecker damage.
Emerald ash borer has become so widespread that homeowners should consider treating valuable ash trees no matter where they are located in Wisconsin. The highest risk of EAB-infestation is within quarantined counties or within 15 miles of a known infestation. Outside of these high-risk areas, the danger of ash trees becoming infested with EAB is probably lower, but it is widely believed that there are additional, undetected EAB infestations within the state. A map of known EAB infestations can be found at the Wisconsin EAB website.
Location isn’t the only consideration when deciding whether to begin insecticide treatments. For example, such treatments are not economically practical for woodlot ash trees; they would need to be repeated every 1-3 years for the rest of the trees’ lives (frequency of treatments will depend on the product and method used).
What you should do
If EAB has been found locally or if you see any of the signs or symptoms of an EAB infestation in your ash trees, search for information online or seek advice from a tree care professional. You can fund a certified arborist at the Wisconsin Arborist Association’s website. Other businesses also conduct EAB treatments.
Some insecticide products can be applied by homeowners but others must be applied by a certified professional. Review the available options before selecting an insecticide and treatment method. Insecticide information can be found on the Wisconsin EAB website and EAB Information Network website.
Only ash trees need to be protected against EAB. Mountain ash and prickly ash trees do not need protection from EAB because they are not true ash trees and are therefore not attacked by the insect.
Consider the following
- Determine whether the tree is worth treating. Some ash trees are too heavily infested to save or have structural or health problems that make them poor candidates for insecticide treatment.
- Trees displaying large amounts of visible woodpecker damage may be too infested to be saved with insecticides. Consult a certified arborist for a professional opinion.
- Landscape trees improve views, increase property values, provide shade and cooling, and contribute to the quality of life in a neighborhood. Weigh those benefits against the expense of a treatment.
- Consider the cost of removing or replacing trees. You might be able to treat your ash tree for more than a decade yet still spend less money than it would cost to remove it.
- The cost of an insecticide treatment will depend on tree size and the product being used. Some products are applied annually; others are applied every two years.
- Check the credentials and insecticide applicator certification of any business you hire to treat your ash trees.
Signs and symptoms of an infestation
Stay informed and be on the lookout for emerald ash borer. Know where the pest has already been found and look for the signs and symptoms of EAB infestation. Watch ash trees closely for the following:
- Woodpecker damage (“flecking”) that looks like pieces of bark have been shaved off and removed;
- Sprouts growing from the base or trunk of the tree;
- Thinning leaves in the upper canopy;
- Tiny (1/8 inch), D-shaped exit holes in the bark; and
- Adult EAB beetles present during the summer.
