Grant Funds Available For Community EAB Management

Posted on by kirsten.biefeld

By: Abigail Krause, DNR Urban Forestry Coordinator

As more detections of emerald ash borer (EAB) are confirmed in Wisconsin’s northern counties, many communities are just starting to address the management consequences that others having been dealing with for more than a decade. Members of the communities in which you live and work may vaguely know of you as “that one person that knows things about trees.” As such you may get asked: are there any cost-share funds or programs out there to help communities deal with EAB?

The answer is yes! Urban Forestry’s grants can be utilized for EAB related projects. Extra great news: urban forestry regular and startup grants are accepting applications until Monday, Oct. 3.

Look For Spongy Moth Egg Masses – Larger Outbreak Possible in 2023

Now that spongy moth* (formerly known as gypsy moth) egg laying is complete for 2022, it’s a good time to look for and dispose of egg masses produced by adult moths over the past two months.

Spongy moth egg masses are tan-colored lumps about the size of a nickel or quarter, and are found on trees, buildings and other outdoor objects. They may also be found in protected places such as firewood piles and birdhouses. Newly produced egg masses will feel firm and appear darker in color than older egg masses, which appear faded, feel spongy and do not contain viable eggs. The current-year egg masses will not hatch until next spring.

In 2022, Wisconsin’s spongy moth population grew for a third consecutive summer due to favorable weather conditions and limited caterpillar mortality from diseases. The outbreak was most dramatic in opposite ends of the state. In southern and southeast Wisconsin, several thousand oak-dominated acres were heavily defoliated and very large numbers of property owner reports were received by DNR staff. In Bayfield County, about 80,000 acres of rural defoliation was reported from aspen-dominated forests. Smaller patches of defoliation were also reported from several other counties.

Register For The Partners In Community Forestry Conference

Posted on by kirsten.biefeld

Sponsored by the Arbor Day Foundation, the Partners in Community Forestry conference will be held in-person in Seattle on Nov. 17 and 18, 2022. This conference is the largest international gathering of urban forestry practitioners, advocates, researchers and government leaders. Bring your skills, your hunger for knowledge and your passion for community forestry as you mingle with like-minded professionals: the thinkers, doers and thought leaders in community forestry. You can view the agenda here.

Partnering events held the same week include the Society of Municipal Arborists’ 58th Annual International Conference and Trade Show (Nov. 14 and 15), the Alliance for Community Trees Day (Nov. 15), Urban Wood Network Academy (Nov. 15) and the Utility Arborist Association Meeting (Nov. 15). There are separate registration and fees required to participate in the partnering events.

Reflections On A Summer Internship With The Wisconsin DNR Urban Forestry Program

Summer is an exciting time for those of us working and playing in the woods, and this year it was especially true as I spent much of it with two great urban forestry students. Kolin Bilbrew and Odell Kimble, both rising juniors in the Urban Forestry program at Southern University in Baton Rouge, Louisiana, spent two months in Milwaukee learning about urban trees, forest management, and data collection. A collaboration between the university, the Wisconsin DNR, and the USDA Forest Service created the internship program, which welcomed Kolin and Odell as its first cohort.

The Stevens Point Forestry Department has created an interactive GIS map called Iverson Park Trees. This map allows a self-guided tree walk that identifies 31 trees that are underused or not common in the area to help residents learn about uncommon trees they can incorporate in to their private property.

The interactive map focuses on Iverson Park’s value as a tree evaluation site. The Stevens Point Forestry Department test plants specific tree species here for a few years to see how well they do before the department decides to buy large quantities of the species and place them throughout the city.

Studies Find Small Urban Forests Can Help Cool Cities

Posted on by kirsten.biefeld

Heat waves are no joke. Temperatures can increase to a dangerous level, exacerbating existing health issues, induce heat stroke, and can even result in death. Increased temperatures do not affect all communities evenly, however.

Studies have found that the highest temperatures and the most heat-related deaths occur in urban areas. Concrete, asphalt, and other paved surfaces often readily absorb and release heat, causing a phenomenon known as an urban heat island effect.

Urban land managers have the potential to mitigate some of this heat island effect with the types of foliage they incorporate into their landscape designs.  Studies find that tree canopy cover can provide shade that reduce the heat absorbed in paved surfaces and lower surface temperature in general. However, many policies that try to implement urban forests as cooling effects focus on large green spaces, which are often not feasible in urban areas.

Tree Ordinances: Why They’re Important, How To Write Them, And Resources For Help

Posted on by kirsten.biefeld

By: Abigail Krause, DNR Urban Forestry Coordinator

Trees contribute to a community’s character and livability. Improved air quality, stormwater management, energy savings, and increased aesthetics are just a few of the frequently referenced benefits provided by trees. However, as with any community infrastructure, trees also need to be managed and maintained.

Ordinances are one step communities can take to shift from reactive to proactive management and avoid large, unexpected maintenance costs.

UW Stevens Point Offering Tree Health Workshop

Posted on by kirsten.biefeld

The University of Wisconsin Stevens Point is hosting a workshop that will be of interest for those who wish to learn how to identify potential hazards and structural health concerns of trees.

The class is called “Leaves Down, Loop Up! A Tree Health Workshop,” and takes place on Nov. 4, 2022 from 1 to 3:30 p.m. and will take place at the Trainer Natural Resources Building. The registration fee is $30 and the registration deadline is Oct. 21, 2022. The listing notes the target audience is for landowners and nature enthusiasts, but municipal employees new to forestry may find it useful.

Hungry, Hungry Japanese Beetles

Japanese beetles (Popillia japonica) are an invasive insect that feed on many plant species. They skeletonize leaves, which means that they eat the material between the veins and often leave lacy veins that turn brown and curl.
