Forest tent caterpillars do not make web nests but may congregate and rest in groups on the bark.
Caterpillars hatch from the eggs of a forest tent caterpillar egg mass.
Forest tent caterpillars are hatching. Egg mass surveys were conducted in Iron, Ashland, Bayfield, Sawyer, Polk, Washburn, Douglas and Burnett counties, and no egg masses were observed. Surveys in Vilas, Oneida and Forest counties found very few egg masses.
Based on this information we expect low numbers and minimal defoliation again this year, but please let us know if you see forested areas with more significant defoliation.

Planting trees in urban areas provides communities with many benefits, but in order to receive the benefits it must first be properly planted. There are several resources that can help ensure that trees are planted properly. Continue reading “Properly plant your trees this season”
In an attempt to find an avenue to get small communities in the fold of beginning, or better managing their community tree resources DNR Regional Urban Forestry (UF) Coordinator, Don Kissinger, resurrected memories of his college days when he and his classmates were given a computer simulation to react and manage a fictitious community forestry program. Through this attempt the collaboration with UW- Stevens Point Professor Rich Hauer and his senior level Urban Forestry Lab class began.

The cabinets in your kitchen, your dining room table, floors in your office, and even the paper you write on are all products made from wood. Usually rural wood is used to make the products, but over the past several years a shift has been made, introducing the use of wood from urban areas to make these, and other, products. For example, urban wood has successfully been used in architecture, creating bowls, staircases, tables and now art. Continue reading “Urban wood used in local art exhibit”
The State of Wisconsin is leading the way in the green industry by providing the nation’s first Arborist Apprenticeship Program, which will include plant health care as well as tree care. Currently, there are three private tree care companies who have signed on five apprentices who are learning and developing their skills under the direct guidance of certified and skilled arborists. More employers are needed to support the program and be willing to hire apprentices. Apprenticeship is a proven method in numerous industries and the benefits greatly outweigh the commitment incurred by employees of all sizes. It provides a structured training program for developing safe, skilled and productive employees and workforce. This program brings additional benefits: providing a career pathway for individuals to join, growing individuals within the industry, getting the arborist profession recognized as a skilled trade with the U.S. Department of Labor, and helping our private businesses and municipalities find and retain qualified employees.

The DNR Urban Forestry Grant program awarded $86,185.66 to five Wisconsin communities for urban forestry projects during our 2017 second round of funding.

The communities who received grants in April include DeForest, Neillsville, Port Washington, Watertown, and Witting. Continue reading “Second round of Urban Forestry grants awarded”
CTMI is a continuing education course specifically tailored to the needs of municipal parks, planning or public works employees who have tree related responsibilities, but do not have a strong background in urban forestry. This training is appropriate for those who manage or contract forestry work, review planting plans, issue permits, or inspect trees. The course focuses heavily on management, rather than the technical aspects of municipal forestry programs. Continue reading “Wisconsin Community Tree Management Institute”
