We are pleased to offer a new resource to communities to help assess, celebrate and share information about your community’s trees and the benefits they provide.

For the 165 communities that we have inventory data on (those communities within the Wisconsin Community Tree Map), we have created summary sheets like the sample shown below. These offer a quick snapshot of your community’s species and structural diversity, canopy cover and the i-Tree derived ecosystem services for both the publicly maintained trees as well as those of the whole community.

storm-damaged treeWith recent storms passing through Wisconsin, communities may still be working on clean-up. Depending on the intensity of the storms and the condition of the trees, damage from high winds, heavy rainfall, hail and lightning can be quite severe. Cracked or broken branches, trunk damage and root failure are some of the main concerns, but also the risk and liability of damage to people and property.

Did your community experience damage from the storms that passed through the state recently? The list below contains resources individuals and communities may find useful. Feel free to include any of these links on your website or in social media posts. Continue reading “Resources For Storm-Damaged Trees”

Cemetery Trees Of Southeast Wisconsin Study Now Available

Cemeteries are important and, to many people, sacred spaces in our communities. The landscaping of these places serves the dead, of course, but can also have a profound impact on the experiences of cemetery visitors and nearby residents. This is accomplished by vegetation and art, which encourages expressions of grief and melancholy but also celebration and hope.

Trees are a prominent part of this landscaping and this mission.

DNR Urban Forestry staff in the Milwaukee office became interested in these spaces and exploring whether we could offer ways to assist cemetery managers. Continue reading “Cemetery Trees Of Southeast Wisconsin Study Now Available”

Controlling Buckthorn With Plants

By Olivia Witthun, DNR Urban Forestry Coordinator, Olivia.Witthun@wisconsin.gov or 414-750-8744 and Elton Rogers, DNR Urban Forestry Coordinator, Elton.Rogers@wisconsin.gov or 414-294-8675

buckthorn The Cover It Up project is a suite of related research projects conducted by multiple partners in Minnesota that are evaluating the ecology and management of buckthorn and other invasive plant species. Buckthorn is an invasive understory plant that was introduced to Wisconsin well over 100 years ago. It was used primarily in hedgerows, prized for its lack of pest issues and the fact it greens up early and holds its leaves well into the fall. These once desirable characteristics are also what turned this non-native into one of our state’s worst invasive species, easily outcompeting our natives, taking over Wisconsin’s forests, riparian woods, savannas, prairies, old fields, roadsides and vacant lots.

Community Spotlight: Tree Canopy Cover On Milwaukee School Properties

By Dan Buckler, DNR Urban Forest Assessment Specialist
Daniel.Buckler@wisconsin.gov or 608-445-4578

The thought of increasing a community’s tree canopy cover is sometimes overwhelming given how many landowners are present. Think about all the stakeholders who have to buy into the initiative, not only with enthusiasm, but likely contributing money and time as well.

Contrast that with a more actionable approach focused on areas where there’s a single landowner or manager.

This was the route taken by graduate student Michelle Hess in a recent paper for a UW-Milwaukee Geography course. Michelle investigated tree canopy on Milwaukee Public Schools (MPS) properties to identify which schools should be prioritized for future greening initiatives, like those organized through ReFlo. The goal was to use canopy data provided by the DNR, identify which schools had lower canopy cover, merge those data with median household income of the local Census tract and come up with a prioritized list of schools in need of tree planting.
