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.

Please Help Guide The Future Of i-Tree

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

Whenever you hear about the benefits that trees provide to a home, community or region, there is a good chance that that information came from i-Tree, a suite of software from the USDA Forest Service and the Davey Tree Expert Company that quantifies forest structure and estimates trees’ benefits to the ecosystem. Within i-Tree, for example, a user can convert easy to-collect tree data, such as species and diameter, into estimates of the tree’s carbon storage, air pollution reduction or ability to prevent rainwater from entering the sewer system.

While i-Tree has been a foundational tool for telling the urban forest story from the local to global levels, the i-Tree program needs your help to adapt to tomorrow’s management challenges. They are urging current and future i-Tree users to attend one of three Town Hall sessions where you can share your thoughts on what i-Tree has meant to your work and how you think it should change for the future. The sessions are organized by experience level, but if you cannot make your preferred time, select any that might work for you. Additionally, if you cannot attend but are interested in providing feedback, please register as comments can be captured during the registration process.

Seeking Input to Proposed Changes in Chapter 1 of Private Forestry Handbook

Chapter 1 of the Private Forestry Handbook is available for stakeholder review and comment through April 4, 2022.

This chapter covers program guidelines for DNR forestry staff regarding their work with private woodland owners, including establishing walk-through service standards and a property walk-through policy. We’re updating this chapter to establish a property walk-through policy since there was no set standard for this important interaction with private woodland owners.

To review and provide feedback on this document, please visit the DNR Forestry Stakeholder Input Page.

Property owners with healthy, valuable ash trees are encouraged to treat them with insecticide this spring to protect against emerald ash borer (EAB). The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99% of the ash trees it infests.

Ash tree branch in West Allis has been damaged by woodpeckers. Sections of bark are missing or have been flecked away.

Spongy moth* (formerly known as gypsy moth) egg masses typically begin to hatch in April as temperatures warm. Now is a great time to inspect your trees for egg masses and treat or remove any masses within reach. Each mass that hatches may produce up to 1,000 leaf-eating caterpillars.

Populations of spongy moths increased in 2020 and 2021 due to favorable weather conditions. This winter’s temperatures have not been cold enough to cause heavy egg mortality. A large rise in caterpillar numbers can be expected in 2022 if weather conditions are warm and dry over the next few months.
