Species Recommendations Available

If you’re reading this, you love trees and have no doubt been asked for your tree species recommendations. The Wisconsin Department of Natural Resources (DNR) Urban Forestry Program is no different. Because species recommendations are an evergreen request, we developed four lists, accounting for a small number of large and small trees in street and park environments.

These lists are not exhaustive (only ten species in each) and any general list of recommendations is somewhat fraught with uncertainty due to the nuanced conditions of specific planting sites. We highly suggest consulting with your local nurseries and other experts who can not only discuss what is available but also provide other recommendations and planting advice. With just a few exceptions, these lists do not include cultivars and varieties, but your local experts can provide that amount of detail.

Arbor Day Celebrates 150 Years

In 1854, J. Sterling Morton, a prominent newspaper editor and publisher, moved from Detroit to what is now Nebraska. He and other pioneers noticed a need for trees, which could act as windbreaks to stabilize the soil and give shade from the sun. Morton planted many trees around his own home and encouraged others to do the same.

On Jan. 4, 1872, he proposed a holiday to plant trees on April 10 that year. This was known as “Arbor Day.” 

Individuals and counties that planted the most trees that day received prizes. About one million trees were planted in Nebraska on the first Arbor Day. Over the next 150 years, Arbor Day celebrations have spread to all 50 states and around the world.

USDA Biological Control Facility Seeks Ash Trees To Battle Emerald Ash Borer

USDA staff cut a ‘bark window’ in green ash to uncover signs of emerald ash borer.

Emerald ash borer (EAB) is an invasive insect from Asia first introduced into the United States in 2002. Since its discovery, EAB has caused tens of millions of ash trees to die and decline. Today, the U.S. Department of Agriculture (USDA) uses ash trees against the pest to help preserve and protect the tree species. They are asking Wisconsin landowners for their help.

Wisconsin landowners have donated live, infested ash trees to USDA’s EAB biological control program. The staff will then use the wood to cultivate EAB’s natural enemies and release them in Wisconsin and 28 other EAB-infested states. The biocontrol staff will need more ash trees to continue producing and releasing these stingless wasps that attack and kill EAB and are hoping more Wisconsin residents will consider donating their ash trees this year.

Treasures In Our Communities

By Dan Buckler, DNR Urban Forest Assessment Specialist, Madison, daniel.buckler@wisconsin.gov or 608-445-4578

There’s a beloved Calvin and Hobbes strip in which the famous duo unearths routine items (rocks, roots, grubs) while digging a hole, but are nonetheless awestruck by what they found, exclaiming “there’s treasure everywhere!”

It’s a lesson that even common things are worthy of acclaim, and a reminder that you can find extraordinary things in unexpected places. 

Big and old trees, for example, turn up in all sorts of environments in Wisconsin: in backyards, next to stores and overlooking cemeteries. One of these Champion Trees that was recently revisited was in scrubby woods between a road and a golf course. From the road, you wouldn’t know that the biggest peachleaf willow in the country used to stand there.

Establishing Long-Term Plots to Understand Urban Forest Trends

By Dan Buckler, DNR Urban Forest Assessment Specialist, Madison, daniel.buckler@wisconsin.gov or 608-445-4578

How many sugar maple trees grow in our urban areas? Which species are exhibiting health declines? How many logs can be produced from removed ash trees? What is the carbon storage of urban forests? Where are invasive species most prevalent?

Please let us know if you know the answers, as that would save some time.

But in the absence of answers to those and many other questions, an incredible project is underway between the U.S. Forest Service, the Wisconsin DNR and contracted private foresters: the Urban Forest Inventory and Analysis (UFIA) program.

Mapping Community Trees

By Dan Buckler, DNR Urban Forest Assessment Specialist, Madison, daniel.buckler@wisconsin.gov or 608-445-4578

The United States features a diverse yet complex group of people and locations. The U.S. Census Bureau regularly undertakes an attempt to catalog those people and places.

Likewise, many communities and organizations survey the trees they manage to better understand and maintain their urban forest.

Rochester Creates Arboretum To Encourage Species Diversity

By Sara Minkoff, retired DNR Urban Forestry Council Liaison

Many smaller Wisconsin communities would like to expand their tree planting efforts but have limited budgets. One village in southern Wisconsin came up with a solution.

Rochester Commons Park has been working to create an arboretum using several grants from the American Transmission Company, an electric transmission utility that aids in promoting natural resources in areas separate from electrical utility service lines.

The western Racine County village of about 4,000 people is lined predominantly with maple trees in the public right-of-way along streets and sidewalks. The goals of the ATC-funded project are to exhibit a variety of species beyond the maples to encourage residents to plant and grow more types of trees and diversify and beautify Rochester.

By Any Other Name, It Is A Pest

By Josh Lancette, Entomological Society of America and Andrea Diss-Torrance, Wisconsin DNR Forest Health

The Entomological Society of America (ESA) has approved “spongy moth” as the new common name for the moth species Lymantria dispar, formerly known as “gypsy moth.”

The ESA gathered a working group of entomologists and forestry professionals to help propose the new name. The name spongy moth—derived from the common name used in France and French-speaking Canada, “spongieuse”—refers to the sponge-like appearance of the egg masses.

The name replaces “gypsy moth” in ESA’s Common Names of Insects and Related Organisms List. The society removed the name in July 2021 for its use as a derogatory term for Romani people.

Learn more about the change from the ESA.

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

The Wisconsin Urban Forestry Council advises the Wisconsin Department of Natural Resources (DNR) on the best ways to preserve, protect, expand and improve Wisconsin’s urban and community forest resources.
