An urban forest is not an island. Trees and maintenance practices in one community inevitably affect the environment in another, while pests, pathogens and other damage agents don’t respect political boundaries. Because of these shared experiences, researchers have partnered with the Wisconsin DNR to assess the current state of publicly managed trees across the Milwaukee Metropolitan Area. Inventories from 40 organizations (mostly municipalities) totaling almost 440,000 trees point to worrying diversity issues and vulnerability to climate change, but also positive planting trends.

An article in the September issue of Arboriculture & Urban Forestry, the research publication of the International Society of Arboriculture, reviews the Milwaukee area’s species diversity, resilience to climate projections, availability of planting sites and more. A high-level summary of those results is below.

From Decaying Park To A Vision For Tomorrow: The Story Of Mauston’s Living Food Pantry

Posted on by patricialindquist

By Randy Reeg, former City Administrator, Mauston

The city of Mauston (Juneau County, Wisconsin) is a small rural city of just under 4,500 people, situated along the I-90/94 corridor in central Wisconsin. Despite having a highly successful local manufacturing economy, a regional medical center and being situated in heavily trafficked regional tourist destination area, Mauston and Juneau County both have lower than average incomes and high levels of poverty. The region is one of Wisconsin’s rural food deserts, and the local food pantry, the Community Sharing Pantry, plays a crucial role in fighting local hunger.

The city of Mauston has seven public parks, and like in most other communities, the amenities, popularity and usage of each park differs greatly. Marachowsky’s Park is an approximately 2-acre mini park located on the city’s west side. It had historically contained a youth baseball field, a picnic shelter, playground equipment and public restrooms. Following the summer of 2019, Mauston’s Summer Recreation Director at the time advocated for the relocation of the youth baseball field to a different park for logistical purposes, including the muddy and mosquito-ridden conditions. The Parks & Recreation Board and City Council both agreed, and by summer of 2020, youth baseball was no longer an activity at Marachowsky’s Park.

Free Data Collection Applications For Tree Inventories

Posted on by patricialindquist

Tree inventories seem like such simple enterprises. Their purpose, essentially, is to determine what trees are growing where, in what shape they’re in and how big they are.

But to do them well requires expertise in arboriculture, proficiency with data collection and familiarity with GIS. And, of course, time. This is why many organizations turn to consulting arborists and foresters to conduct inventories and write management plans – they have that expertise and experience to see those projects through.

However, for some smaller or specialty projects, an organization may decide to collect tree data itself. For these efforts, a list of free digital data collection applications is available on the DNR website.

The Wisconsin Department of Natural Resources (DNR) is now accepting applications for Urban Wildlife Damage Abatement and Control (UWDAC) grants. UWDAC grants help urban areas develop wildlife plans, implement specific damage abatement and/or control measures for white-tailed deer and/or Canada geese. 

UWDAC grants provide a 50% cost share with a maximum award of $5,000. The grant is available to any town, city, village, county or tribal government located within an urban area. Check out the complete list of eligible urban areas.

Grant eligible expenses include:

  • Developing an urban wildlife population control plan
  • Monitoring wildlife populations and establishing population estimates
  • Removing deer using sharpshooters as part of a DNR approved project
  • Trapping deer and geese
  • Implementing managed hunts
  • Removing resident Canada geese by approved DNR methods
  • Performing required health and tissue sampling
  • Processing, distributing or disposing of geese or deer to a charitable organization
  • Modifying habitat
  • Implementing any other wildlife control or damage abatement practices approved by the DNR

Avoid Invasives During Fall Recreation

Don’t move firewood! Many State Parks and Forests stock firewood right at the campground entrances. Use these stands or other local sources that are no more than 10 miles from your destination to avoid spreading invasive species. / Photo Credit: Wisconsin DNR

Whether you prefer to enjoy Wisconsin’s beautiful fall weather on a hike, bike, ATV/UTV or on the water, the Wisconsin Department of Natural Resources (DNR) urges those enjoying the outdoors to take a few precautions to avoid bringing invasive plant species along for the ride.

The Wisconsin Council on Forestry has created a set of guidelines titled “Invasive Species Best Management Practices for Outdoor Recreation.” These voluntary guidelines include steps recommended for individuals to minimize the inadvertent spread of invasive species.

Here are a few universal Best Management Practices (BMPs) for outdoor recreation, along with a few examples of these practices in action.

Pink-Striped Oakworm Population Remains Low

Pink-striped oakworm is a native fall defoliator. Fall defoliators affect the health of trees less than defoliators that occur in the spring.

Although literature states that high populations of this caterpillar can create significant defoliation, no defoliation was noted in the area this caterpillar was observed in Oneida County.

Not-So-Notorious Native Buckthorn

Most of the rather frequent buzz about buckthorn revolves around the two non-native, invasive types: common and glossy. The Wisconsin Department of Natural Resources (DNR) reminds the public that while these aggressive plants and serial invaders are common in Wisconsin forests, there is also a benign and native buckthorn that gets much less attention.

Many people are surprised to learn about this small shrub that has eluded notoriety, unlike its close relatives. Native buckthorn, also known as alder-leaved buckthorn (Rhamnus alnifolia), is a demure shrub that doesn’t grow much taller than 3 feet and prefers wet areas with calcium in the soil.

Time To Seek Out Spongy Moth Egg Masses

The Wisconsin Department of Natural Resources (DNR) is encouraging property owners to seek out and dispose of spongy moth egg masses, which were produced by adult moths during the summer.

Each spongy moth egg mass contains hundreds of eggs that will hatch into hungry, leaf-eating caterpillars in the coming spring. Large numbers of these invasive caterpillars can be a tremendous nuisance that may cause tree mortality.

When temperatures begin to cool and back-to-school sales emerge, our thoughts turn to pumpkin spice, sweater weather and all things fall décor.

But as you gear up for spooky season this year, the Wisconsin Department of Natural Resources (DNR) reminds you to beware of using invasive plants in your decorations.

Aphids — and the honeydew they produce — have made their mark on trees in Wisconsin during 2023.

Midway through the summer, oak trees in areas of Vilas and Oneida counties were buzzing with activity. During September, beech trees in eastern Wisconsin became busy with a different species of aphid.

A look at the two situations:
