Celebrate Arbor Day Using Social Media (See Our Suggested Posts Below)

Posted on by janness

For the last few years, our urban forestry team has been writing social media posts for Wisconsin communities to post during Arbor Week. We encourage you to use social media to celebrate the many benefits of trees and inform the public on proper tree care. Here are some tips to get your messages noticed followed by sample social media posts.

  • Use pictures of local trees in your posts to inspire community members to get out and explore the local urban forest.
  • Share pictures of past tree-planting events to generate enthusiasm.
  • Ask a question to encourage engagement.
  • Include links to more information.
  • Share stories about interesting local trees such as the oldest tree, the biggest tree, the most unique-looking tree or a tree that has survived a catastrophic event.
  • Do you have any local celebrities in your community? Have the mayor or a librarian or school superintendent share stories about their favorite trees.

In 2025, oak wilt was detected for the first time in Hughes Township, Bayfield County, a northern Wisconsin location where oak wilt remains uncommon. There were no new county finds in 2025.

Based on the findings in 2025, the maps in the Oak Harvesting Guidelines To Reduce The Risk Of Introduction And Spread Of Oak Wilt (the oak wilt guidelines), oak wilt fact sheet and were updated. The maps in the oak wilt guidelines are good through the end of 2026.

Oak Wilt High Risk Period Quickly Approaches

The pad will create cracks in the bark, where beetles can enter and visit the pad and become covered in spores. They will then leave and move on to infect new trees through open wounds. / Photo Credit: Wisconsin DNR

It is again that time of year to pause operating in oak stands or pruning oak trees during the high-risk period for oak wilt, which begins in April. The high-risk period begins April 1 in the South, April 15 in the North, and ends in both zones on July 15.

The high-risk period is determined by when the beetles that carry the fungus that causes oak wilt have emerged for the year and when they are carrying the highest number of fungal spores. When wounds are created by logging operations or other activities that expose sapwood, the beetles carry the fungus to the wounded tree, and the disease process begins.

As winter transitions into spring, you may notice patches of tree bark that have been removed. But what did the damage?

Several animals, including squirrels and porcupines, can chew or strip bark from trees. This can occur on hardwoods and conifers, older trees and young saplings. Damage can be enough to kill branches or even the entire tree.

Wisconsin experienced a polar vortex in late January 2026, and temperatures got chilly throughout the state, even reaching close to -40⁰ F in some places! Although it has warmed up, the cold weather is still fresh in everyone’s minds, leaving insect and forest lovers alike wondering how insects survive temperatures that cold.

The Wisconsin Department of Natural Resources Forest Health staff has received several questions over the past month about how insects survive cold weather in winter and whether the January temperatures were cold enough to kill insect pests.
