It takes more than one celebration to pay tribute to Wisconsin’s 17 million acres of rich, diverse forestland.

So, the state has come up with multiple ways to acknowledge the value of trees to Wisconsin’s ecology, economy, health and way of life. Three of the biggest ones are taking place in April:

  • Earth Day will be observed on Wednesday, April 22.
  • Arbor Day is set for Friday, April 24.
  • Forest Appreciation Week runs April 20-24 statewide, covering both of those dates.

This past winter, “exploding trees” went viral on social media. Many news outlets followed up with a more realistic explanation of the dramatically named phenomenon, pointing out that while the bitter cold can cause sudden cracks to form on trees, the trees don’t truly explode.

But what happens to those damaged trees as we warm up and move into the growing season?

Hermit flower beetles (Osmoderma spp.) are very large scarab beetles, sometimes called leather beetles.

Three Osmoderma species can be found in Wisconsin, though none are common. Adult beetles look big and beefy but are harmless, eating a little pollen, feeding on ripe fruit and sipping nectar and tree sap during their adult life.

An active winter weather season for snow, freezing rain and fluctuating freeze/thaw temperatures has exposed white pine along roadways to salt spray damage.

Vaporized salt spray droplets from vehicle traffic can drift into the air and settle onto vegetation, with the heaviest deposits occurring within 150 feet of a roadway.

Invasive jumping worms are worrisome for several reasons, but here’s one of the main ones: It can be difficult to tell you even have them until they’ve already done their damage.

That makes this time of year important, because the best way to avoid damage from jumping worms, which can be substantial and long-lasting, is to prevent them from getting into your garden, yard or forestland in the first place.

As winter begins to loosen its grip on Wisconsin, many gardeners have turned their thoughts to that unmistakable harbinger of spring: Planting season.

While dreaming of spring blooms and designing your next garden or landscape layout, consider that invasive plants may try to weed their way into your plans.

The Wisconsin Department of Natural Resources (DNR) has a team of Forest Health specialists that focus on problems affecting state, county and municipal forests and private forests larger than 10 acres.

But, to twist a cliché, if you can’t see the forest for the trees when it comes to your yard trees, expert help is a few clicks away.

Open MFL And FCL Updates Shown In Public Access Land Map

By Wisconsin Department of Natural Resources

Managed Forest Land (MFL) and Forest Crop Land (FCL) open for public recreation have been updated in the DNR Public Access Land (PAL) mapping application to show the approximate on-the-ground area of these private forest lands open for recreation.

These areas are based on the MFL or FCL map, the tax parcel(s) and legal description(s) of the enrolled land. The features replace the point representation, which only identified the public land survey system (PLSS) quarter-quarter section of open MFL and FCL land. Users then had to download an MFL or FCL map to see the area of open land.

This update will allow users to see the approximate open MFL and FCL areas in relation to other basemap layers, such as roads, other public lands and tax parcels. The MFL and FCL maps are still available for download after selecting a specific property and viewing the detailed information for that enrollment.

Additionally, an access point layer has been created showing the access point and a description of the access for open MFL and FCL properties where access is not from an adjacent public road or other public land.

The MFL/FCL PAL help document has also been updated.

Questions or comments can be submitted through the PAL Help link available in the Terms of Use upon opening PAL, or by clicking the “Info” button in the lower right corner of the map.

 

 

 

Arbor Day Caps Off A Week Of Environmental Action And Celebration

Don’t think of Arbor Day as the end of Forest Appreciation Week, think of it as the beginning of tree planting season! Arbor Day is a celebration rooted in a simple but powerful idea that planting trees is an investment in the future.

The first Arbor Day started as a community effort to restore trees in Nebraska. The secretary of the Nebraska Territory at the time, J. Sterling Morton, led this effort, and on April 10, 1872, the first official Arbor Day was celebrated. The success of the first tree-planting holiday spread quickly, and today, it is observed in all 50 states and in many countries around the world. The Arbor Day Foundation estimates tens of millions of trees are planted each year in honor of Arbor Day. Continue reading “Arbor Day Caps Off A Week Of Environmental Action And Celebration” →
