Calling all tree inventories!

Posted on by patricialindquist

Do you have a tree inventory from the last five years that you’d want to appear on the Wisconsin Community Tree Map, a compilation of tree inventories from around the state? Or perhaps you already have an inventory there, but want to submit an update? Well, there’s no time like the present to get those submitted to the DNR to appear on the map. The tool is a useful way to showcase your community trees, query different groups (e.g. all large ash trees) and contribute to a better understanding of urban forests in Wisconsin.

Fighting invasives together through responsible firewood practices

This time of year, many Wisconsinites warm up with firewood, whether that’s in a wood stove for the home or a bonfire with family and friends. While firewood is one of the most sustainable heat sources available, the forests that produce it are threatened when firewood infested by invasive species is moved long distances. Fortunately, we can reduce this threat together through responsible use, movement and sale of firewood and wood products.

Check your trees for EAB and plan for spring

The cold winter months are a great time to think about emerald ash borer and whether ash trees in your yard are suitable for treatment. The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99 percent of the ash trees it infests.

Two side-by-side images depicting different stages of flecking on ash trees - on left side is light flecking in the upper canopy of a tree, on the right side is more severe flecking that extends down the trunk of the tree

Woodpecker flecking is an early sign of EAB infestation when it appears in the tops of trees (left). As the infestation progresses, flecking continues down the trunk and into lower parts of the crown (right).

Arbor Day Foundation launches three new recognition programs

Posted on by patricialindquist

Now more than ever, trees and forests are a vital component of healthy, livable, and sustainable communities, in the U.S. and around the globe. Along with its partners such as the Wisconsin DNR, the Arbor Day Foundation is seeking ways to link together those that plant and tend urban trees and forests for the benefit of humankind.

In 2019, the Foundation launched three new recognition programs to appeal to three different audiences, three different owners and managers of urban greenspace:

For best selection, place your nursery orders soon!

Posted on by patricialindquist

As we settle into winter, the spring planting season may seem a long way off, but it’s best to get a head start. December is an ideal time to contact your nursery supplier and place your order for spring. By ordering your trees now, you’ll have more trees to choose from and a greater chance of finding the species you want.

Not sure which species to plant? Check out the DNR’s Tree learning center webpage and the replanting tab of the Emerald ash borer community toolbox. These resources and tree selector tools can help you discover trees that may perform well in your community.

Once you’ve identified the best species for your area, draw up a planting plan that includes as many different species as possible. If you have a tree inventory, make sure to consult it. Your goal is to create an urban forest that is as diverse as possible. By planting with species diversity in mind, you are helping to protect your forest from future pests and pathogens.

To learn more about how to design a diverse urban forest, take a look at our Diversity rules and considerations pdf.

Are you planning to treat your ash trees? If not, stay safe and save money by removing them ASAP!

The emerald ash borer (EAB) will kill nearly all of Wisconsin’s ash trees that are not protected by insecticides. If you have healthy ash trees in your yard, you have an important decision to make: protect your trees with insecticides or have them removed. Either way, time is of the essence. If you delay in treating your ash trees, the treatment may be less effective. And if you wait to remove them, removal costs will be greater and safety hazards will only get worse.

What makes infested trees so dangerous?

The structural integrity, or strength, of ash branches and tree trunks begins to decline as soon as the tree becomes infested and the wood begins to dry. Lower moisture content increases the risk of branch and trunk breakage, and the timing of breakage is usually unpredictable. Infested trees may also have total trunk failure soon after death, further increasing the chance of dangerous impacts to people and property.

Look for gypsy moth egg masses

Posted on by margueriterapp

Fall is an excellent time to look for and dispose of gypsy moth egg masses that were laid in the summer. Since egg masses usually don’t hatch until April, information gained from fall/winter surveys can be used to avoid gypsy moth damage before the following spring and summer.

Spraying egg masses with oil kills the eggs inside, preventing hundreds of caterpillars from hatching next spring.

2019 First Downs for Trees

Posted on by margueriterapp

Green Bay Packers and DNR staff plant a ceremonial Sterling Linden tree in Titletown to help offset the Green Bay Packer’s carbon footprint produced by traveling to away games. Trees naturally sequester carbon dioxide, providing a long-term solution to the problem because trees sequester more and more carbon as they grow larger. This marks the 9th year of the Packer’s First Downs for Trees (FDFT) Program which has planted 5,144 trees to date throughout Brown County.

The continuous transformation of Havenwoods State Forest

Posted on by margueriterapp

On the north side of Milwaukee is a park with a name more evocative of a medieval forest than one of the most densely populated parts of modern Wisconsin. Yet its history is as rich, its canopy as green and its deer as plentiful as any royal hunting ground. Havenwoods State Forest is Wisconsin’s only urban state forest and thus plays a critical role in connecting urban populations to nature.
