The Wisconsin Department of Natural Resources (DNR) today announced Urban Forestry Grant Program recipients for the 2024 grant year. The program helps fund projects consistent with state and national goals for increasing the urban forest canopy.

The Urban Forestry Grant Program is distributing almost $805,000 in grant funds, with $554,680 in state funding and an additional $250,066 in federal funding. A dollar-for-dollar match puts the estimated cost of these projects over $1.6 million. In total, 58 applications were selected to receive funding, with awards ranging from $1,580 to $25,000.

New-And-Improved USDA Plant Hardiness Zone Map

Posted on by janness

The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennial plants are most likely to thrive in a given location. The map is based on the average annual extreme minimum winter temperature, displayed as 10-degree Fahrenheit zones and 5-degree Fahrenheit half zones.

WI USDA Plant Zone MapThirty years of data was reviewed by a group of horticultural, botanical and climatological experts for the latest USDA Plant Hardiness Zone Map revision. This was determined to be the best balance between the fluctuations of year-to-year weather variation and the concept that, during their lifetimes, perennial plants mostly experience what is termed “weather” rather than “climate.”  A complex algorithm was used for this edition of the Plant Hardiness Zone Map to enable more accurate interpolation between weather reporting stations. This method accounts for factors such as elevation change and proximity to bodies of water, making mapping zones more accurate. Continue reading “New-And-Improved USDA Plant Hardiness Zone Map” →

Winter Work: Invasive Honeysuckle Treatment

They may have sweet-sounding names, but Eurasian bush honeysuckles (Lonicera spp.) can bring a bitter taste to your mouth if found in your woodlands.

Originating as horticultural plantings, this group of upright woody shrubs is now widespread in Wisconsin and the upper Midwest.

Invasive honeysuckle shrubs are among the earliest plants to leaf out in the spring and the last to lose their leaves in the fall. This extended growing season allows them to outcompete other plants for nutrients and sunlight, casting dense shade on the forest floor.

Native honeysuckles are also present in Wisconsin. Several identifying characteristics can help you determine if your honeysuckle is a native species or one of the invasive varieties. When in bloom, the flowers of invasive Bell’s, Morrow’s and Tartarian honeysuckles are easily distinguished. Without the blooms, the easiest methods to determine non-native honeysuckle from the native plant include looking for shaggy, peeling gray-brown bark and checking the pith.

The pith (inner tissue of the branches and stems) can be observed by breaking off an older branch. If the pith appears white, the shrub is native honeysuckle. If the pith is brown and hollow, it is likely one of the invasive bush versions.

Winter is a great time to treat invasive honeysuckle shrubs on your property since most other plants have gone dormant for the season. Winter herbicide applications are highly successful on freshly cut stumps, provided snow does not cover the cut surface. Basal bark applications may also be used on snow-free surfaces.

Stump cutting should be followed by herbicide treatments, as vigorous resprouting may occur from shrubs cut in winter but not treated with herbicide. Learn more about invasive honeysuckles and how to manage them on the Bush honeysuckles fact sheet from Renz Weed Science at the University of Wisconsin-Extension.

Please Report Beech Scale Outside Of Door County

Earlier this year, we reported that high populations of the non-native insect beech scale (Cryptococcus fagisuga) were identified for the first time in Marinette and Sheboygan counties. Since then, several more sites with moderate or high scale populations have been identified (see map).

Make Your 2024 Spongy Moth Treatment Plans Early

If the 2024 spring and summer weather conditions are favorable for the spongy moth (Lymantria dispar) population, the current outbreak will continue and spread to other parts of Wisconsin. Property owners are encouraged to examine susceptible host trees (including oak, birch, crabapple, aspen and willow) and make plans to manage them.

In summer 2023, Wisconsin saw a record amount of defoliation. State agencies received many calls from property owners urgently seeking a tree care business to control a large caterpillar infestation.

Jenn Janness Joins DNR Urban Forestry Team

Posted on by patricialindquist

DNR Urban Forestry welcomes Jenn Janness to the team. She will be focusing on urban forestry outreach and supporting the Urban Forestry Council. Jenn shares this introduction of herself:

I have spent most of my career involved in outreach, training and nonprofit management. I worked at UW-Oshkosh as an AmeriCorps program director for many years before becoming a job skills instructor and then a program coordinator for a transitional housing program. Since 2021, I have been employed with the DNR at the Kettle Moraine Northern Unit and at Brule River State Forest as a Natural Resources Educator and Park and Rec Specialist. I look forward to learning more about urban forestry and combining my communications skills with my passion for conservation. Luckily, the Brule DNR had space so I can continue to enjoy beautiful views out of the windows of their historic building while I work! In my free time, I enjoy exploring the outdoors, crocheting and reading in my hammock. I love to travel so am looking forward to visiting different areas of the state as part of my new position!

LEAF Resources For Connecting Kids With Nature

Numerous research studies support the idea that green spaces and vibrant tree canopy at school campuses are important for students’ academic and socioemotional growth. But that can be easily overlooked during construction, design build and as our school grounds in our communities age over time. Municipal foresters and tree boards can be part of driving positive change.

Three critical preconditions for learning – ability to concentrate, intrinsic motivation and manageable levels of stress – have been linked to green schoolyards in recent research[1]. At the LEAF K-12 Forestry Education Program, a partnership between the DNR Division of Forestry and University of Wisconsin – Stevens Point, our resources can help you get students outdoors and connected with nature. For example, our Forest Mapping activity provides learners with hands-on outdoor mapping investigations of their school campus.

Please Submit Trees Planted This Year

Wisconsin Tree Planting MapAutumn is a great time to plant trees. After the trees go in the ground, please take a few minutes to document the effort in the Wisconsin Tree Planting Map. The map was designed to help track trees planted to advance the state’s pledge to the Trillion Trees Initiative.

While the DNR may be able to track the ultimate destination of seedlings grown at the state nursery, or trees which have been funded by DNR grants, there are so many others planted across Wisconsin which go undocumented. The planting map was designed to help fill that void and to ensure that those trees are accounted for in our tallies.

Whether it was a planting of one tree or a thousand, take a couple minutes to submit your information through an easy-to-use survey.

Wood Innovations Grant Program

Posted on by patricialindquist

The USDA Forest Service is announcing the availability of $20 million in funding from the Bipartisan Infrastructure Law and Inflation Reduction Act to support projects that will substantially expand and accelerate wood products and wood energy markets throughout the United States. Additional funds from annual agency appropriations will be subject to availability. The intent is to stimulate, expand and support U.S. wood products and wood energy markets to support long-term management of National Forest System and other forest lands while enhancing the economic and environmental health of communities.

Eligible applicants include for-profit entities, state and local governments, Indian Tribes, school districts, communities, not-for-profit organizations, institutes of higher education and species purpose districts (e.g., public utilities districts, fire districts, conservation districts and ports).
