Balsam Fir Needle Rust

Balsam fir needle rust is infecting current year needles on balsam fir trees in north-central Wisconsin. Balsam fir needle rust has white pustules that emerge from the lower surface of infected needles. Infected needles will turn yellow and the combination of white pustules and yellow needles gives the trees a pale, ghostly appearance from a distance.

Pine Bark Adelgid Causes Needle Stunting

Posted on by patricialindquist

Linda Williams, DNR Forest Health Specialist, Woodruff, Linda.Williams@wisconsin.gov or 920-360-0665. 

Pine bark adelgids are tiny insects that suck the sap of white pines. Once they insert their mouthparts into the tree, they won’t move any more during their lifetime, so for protection, they grow a white, woolly covering around themselves. A young, white pine plantation in Vilas County is suffering severely stunted needles from the 2020 growing season due to very high populations of pine bark adelgid. 

All branch tips on this white pine sapling have needles that were stunted by heavy populations of pine bark adelgid.

Giant Hogweed: Rare But Harmful

Posted on by patricialindquist

By Bernie Williams, DNR Invasive Plant Specialist. Bernadette.Williams@wisconsin.gov or 608-444-6948. 

Giant hogweed is a non-native, invasive plant that has gradually gained a foothold in the northeastern U.S. Once popular for its massive size and white umbrella-like flowers, it was introduced as an ornamental as early as 1917. Now known for its harmful blisters, it is recognized as a public health hazard and controlled wherever possible.

Things just keep getting drier and it seems like there is no end in sight. The trees are thirsty, and they need your help!

Watering Newly Planted Trees

Newly planted trees need extra watering until they are established. The amount of water depends on tree size and on your soil type (sandy versus clay).

  • 1-2 weeks after planting: water daily.
  • 3-12 weeks after planting: water every 2 to 3 days.
  • After 12 weeks, water weekly until roots are established.

Watering Tips

  • Deep watering is best. Try to get the soil wet to a depth of at least 6 inches.

Public Awareness Ideas For Watering Trees In A Drought

Posted on by patricialindquist

By Olivia Witthun, DNR Urban Forestry Coordinator, Plymouth, olivia.witthun@wisconsin.gov, 414-750-8744 

Most of you are doing your best to keep things watered, but you could always use some help. Below are a few ideas for public awareness and pleas to get homeowner assistance in watering trees. As always, contact your DNR Urban Forestry staff if you’d like more specific examples.  

  • Social media is a great avenue to get these types of messages out. Use your community’s Facebook, Twitter and other social platforms to your advantage.
  • Consider dropping off a doorhanger reminding folks to water trees. Perhaps work it into your watering schedule; each address you stop at gets a doorhanger.

Fire danger remains high

Posted on by Kirsten Held

Normally by this time of year, spring wildfire danger is over. Due to minimal precipitation, the danger isn’t over yet.

Since June 1, the DNR has responded to 106 wildfires in DNR protection areas. Fire danger remains elevated in many parts of the state, with much of the northern half of Wisconsin currently experiencing High to Very High fire danger.

DNR-issued burning permits will be suspended in some counties. As always, check for restrictions in your area daily after 11 a.m.

Be cautious with anything that could inadvertently start a wildfire. Ensure all tow chains are secured, avoid parking vehicles on dry grass, keep ATVs and UTVs on the trail and avoid any fireworks use. If you’re doing any woods work, avoid setting down hot chainsaws on dry grass or leaves.  Never leave your campfire unattended and make sure it’s fully out – drown and stir until all material feels cool.

ATC Offers Funding For Planting And Pollinator Habitat Projects

Posted on by patricialindquist

Recognizing that trees and vegetation are among the features that make communities special places for residents and visitors, American Transmission Company (ATC) will continue to offer funding for planting projects in communities in its service area through its Community Planting and Pollinator Habitat programs.

The Community Planting Program provides financial support to eligible cities, villages, towns, counties and tribes in ATC’s service area for planting projects on public property, outside transmission line rights-of-way.

The Pollinator Habitat Program provides funding for site preparation; purchasing seed, plugs or plants; labor and installation; or other activities to establish quality pollinator habitat. Unlike the Community Planting Program, the Pollinator Habitat Program promotes planting low-growing vegetation within a transmission line right-of-way.

The Dangers And Costs Of Infested Ash Trees

The emerald ash borer (EAB) will kill nearly all of Wisconsin’s ash trees that are not protected by insecticides. To help the public understand why it’s important to act against EAB, the DNR created a publication aimed at homeowners that addresses the dangers and costs of infested ash trees. Urban forestry professionals may wish to share this flyer with those who ask questions on these topics.

The key message of the publication is this: It’s crucial to decide ASAP whether to protect your ash 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.
