A simple idea, to celebrate planting trees, and it’s grown into a national holiday: Arbor Day.

Arbor Day’s roots began in the late 1800s in Nebraska where, according to the Arbor Day Foundation, residents of Nebraska City felt a lack of trees in their community. The secretary of the Nebraska Territory at the time, J. Sterling Morton, proposed a statewide tree-planting holiday, and on April 10, 1872, the first Arbor Day was celebrated.

Feel free to use the suggested messages provided below or develop your own creative tree campaign. We encourage you to use pictures of local trees in your posts to inspire community members to get out and explore the forest outside their door.

“Acts of creation are ordinarily reserved for gods and poets. To plant a pine, one need only own a shovel.”

Those were the words of Wisconsin’s most prominent conservation expert, Aldo Leopold, who authored the famous book, “A Sand County Almanac” among his many achievements.

This month, everyone in Wisconsin will have the chance to follow Leopold’s advice – even if in a small way, because many small efforts can add up to a prominent positive impact on Wisconsin’s trees and forests.

The Wisconsin Urban Forestry Council presents annual awards for furthering urban forestry in the state.

The Wisconsin Urban Forestry Council recently announced its annual awards honoring those dedicated to protecting, preserving and increasing the number of trees that line city streets, fill community parks and beautify neighborhoods throughout the state.

This year’s recipients were announced at the 2025 Wisconsin Arborist Association/DNR Urban Forestry Conference in Green Bay. The categories and winners are: Continue reading “Wisconsin Tree Leaders Recognized For Exceptional Community Service”

Oak wilt is a serious disease that kills trees in the red oak group (including pin oak, northern red oak and black oak) and weakens those in the white oak group (bur oak, swamp white oak, white oak and English oak).
