Urban Forestry Sustainability Standards to be Developed

Posted on by patricialindquist

The Sustainable Forestry Initiative Inc. (SFI) has launched a partnership to develop a new SFI Urban and Community Forest Sustainability Standard for application in North America and potentially globally. SFI will collaborate with five urban forestry leaders: American Forests, Arbor Day Foundation, the International Society of Arboriculture, the Society of Municipal Arborists, and Tree Canada.

A task group composed of leading experts will develop the new SFI Urban and Community Forest Sustainability Standard. The partnership and task group will explore opportunities to seek remedies for the climate crisis and other serious challenges that urban forests are ideally positioned to help address, including access to public spaces, social cohesion and more.

Celebrate Arbor Day Using Social Media (Check Out Our Suggested Posts Below)

Due to the ongoing COVID-19 pandemic, the Arbor Day Foundation has suspended their requirement to hold a public Arbor Day celebration in 2021. Communities will be able to maintain their Tree City USA designations without meeting this standard. An Arbor Day proclamation is still a requirement.

As an alternative to a public gathering, we encourage you to use social media to celebrate trees and their many benefits. Social media is an excellent tool for spreading the message that trees and tree care/management are vitally important to our communities.

Feel free to use our suggested messages here, or develop your own creative tree campaign.

Treat Your Valuable Ash Trees Against Emerald Ash Borer

Ash tree branch in West Allis has been attacked by woodpeckers looking for larvae to eat.

Municipal foresters and property owners with healthy, valuable ash trees should consider treating the trees with insecticide this spring to protect against emerald ash borer (EAB). The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99 percent of the ash trees it infests. 

Woodpecker damage during the winter is often the first sign that an ash tree is infested, so it is essential to examine your ash trees. Now is an excellent time to consider insecticide protection because the treatments are usually done 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 have low or moderate levels of woodpecker damage.

Species Diversity In The Urban Forest: A Short Guide For Homeowners

Posted on by patricialindquist

“What kind of tree should I plant?” We are often asked that question as urban foresters. For me, the first thing that comes to mind is, “not a maple!”

Approximately 36% of trees in the Wisconsin Community Tree Map are maples.* Why is this a bad thing? All it takes is a pest like the emerald ash borer (EAB) or a disease like Dutch elm disease that targets maples, and suddenly, one-third of the urban canopy is destroyed.

By planting smaller quantities of many different species, we create a more resilient urban forest less affected by any single threat.

The Wisconsin Department of Natural Resources (DNR) recommends planting no more than 10% of a genus (for example, maples or oaks) and 5% of a species (such as sugar maples or bur oaks). Most Wisconsin communities are far from meeting those targets.

Protect Oak Trees From Oak Wilt By Pruning After July, Not Before

Posted on by eleanorvoigt

By Don Kissinger, DNR Urban Forester, 715-348-5746 or Don.Kissinger@wisconsin.gov; Paul Cigan, DNR Forest Health Specialist, 715-416-4920 or Paul.Cigan@wisconsin.gov

The Wisconsin Department of Natural Resources (DNR) urban and forest health specialists recommend not pruning or cutting oaks from April through July to protect oak trees from the often fatal oak wilt disease.

The spring season often draws property owners outdoors to soak up rays of long-awaited sunlight, breathe in some fresh air and begin seasonal yard maintenance and cleanup projects. While spring is a time to dust off yard tools like rakes, shovels and weed clippers, when it comes to the health of oak trees, keeping those chainsaws and trimming tools a safe distance away will go a long way to ensure that your trees stay healthy for many more spring seasons to come.

Look For Gypsy Moth Egg Masses And Prepare For Hatch; DATCP Slow-The-Spread Treatments Announced

Posted on by eleanorvoigt

By Bill McNee, DNR Forest Health Specialist, Oshkosh, Bill.Mcnee@wisconsin.gov or 920-360-0942

Typically, gypsy moth egg masses hatch in April as temperatures warm. Now is a great time to do an egg mass inspection to look for unknown infestations and treat or remove any masses within reach. Each mass can result in 500 to 1,000 leaf-eating caterpillars.

Egg masses are tan-colored lumps and vary from about the size of a nickel to a quarter. They can be found on many outdoor surfaces such as tree trunks, the undersides of branches, buildings, rocks, fences, retaining walls, firewood piles and picnic tables.

2021 Arbor Day Foundation Recognition Program Standards

Posted on by patricialindquist

Tree City, Tree Campus and Tree Line USA program participants: please review the Arbor Day Foundation’s following expectations regarding the 2021 program recognition standards.

Tree City USA Standard 4 – Proclamation and Arbor Day Observance: We will require a signed Arbor Day proclamation on all 2021 applications. Arbor Day observances and celebrations will not be required, but cities will be highly encouraged to publicize their community’s recognition as a Tree City or celebration of Arbor Day.

Examples of things communities could do to observe while socially distancing: Facebook live tree planting, social media post encouraging citizens to celebrate Arbor Day, newspaper article, radio ad, etc.

Gypsy moth egg masses on the underside of a maple branch.

Gypsy moth egg masses are expected to start hatching in April as temperatures warm. Now is a great time to do an egg mass inspection to look for unknown infestations and treat or remove any masses within reach. Each mass that never hatches can result in 500 to 1,000 fewer leaf-eating caterpillars.

Egg masses are tan-colored lumps about the size of a nickel or quarter. They can be found on many outdoor surfaces, including tree trunks, undersides of branches, buildings, rocks, fences, retaining walls, firewood piles and other outdoor objects.

Staff Highlights of 2020

Posted on by patricialindquist

As the year draws to a close, we asked DNR urban forestry staff to reflect on the last twelve months and choose their top highlight – whether it’s a project they’re especially proud of, a new partnership or a deeper relationship with coworkers. Here are their responses:

“The highlight of my year has been watching the partners we support achieve lasting impacts via their Urban Forestry projects. Two immediately come to mind. Restoration Of Our Trees Sheboygan (ROOTS) kicked off their EAB Mitigation Grant Program by funding five separate projects in Sheboygan County communities for a total project value of $165,500. The other is Cedarburg Green who instituted a public awareness campaign to encourage community leaders to refund the city’s tree planting budget. Their campaign consisted of a common council presentation, an educational workshop and tree sale for residents, Arbor Day plantings, student art and writing contests, tree benefit tags, multiple news articles and a “Trees of Distinction” booklet, video and walking tour.”  -Olivia Witthun, East Central Regional Urban Forestry Coordinator
