The Northwest Illinois Forestry Association will tour Brad Peterburg’s woodland on South Rodden Road in Jo Daviess County at 10 a.m. June 22. Peterburg will give his perspective on the aerial application of glycophosphate to attack bush honeysuckle in the fall of 2017 and 2018. Consulting forester Kevin Oetken will be present to discuss effects of the spraying and his experience with other spraying projects.
Peterburg has reached out to the Illinois Department of Natural Resources to assess the impact of spraying on non-target native species.
Peterburg’s 100-acre farm features equal parts of cropland, woodland and pasture. Bush honeysuckle has invaded the woodland and after attempts at mechanical eradication had failed, Peterburg tried aerial spraying of the herbicide glyphosate last fall following consultation with IDNR and professional forester. Timing was tricky to wait for oak dormancy yet strike honeysuckle while its leaves were still green.
“The woodland is mixed aged with hardwoods and less desirable trees,” Peterburg said. “I have performed some crop tree release on the property but would not describe it as well-managed from a woodland perspective. I have tried planting some small oak seedlings but the deer have essentially eaten all of them. I have tried other methods of controlling honeysuckle (i.e., pulling out by the root and cut-stump treatment) but the honeysuckle has grown back worse than ever.”
Directions: From Elizabeth, drive five miles west on US 20, then turn south on South Rodden Road. About 1.5 miles south, the woodland occupies one-third of a 100-acre farm on the west side of the road; look for a sign. Park on the west side of the road or in the grassy area adjacent. There will be a good one-quarter mile hike to the woodland. Wear boots and bring bug spray.
This tour is open to the public; all are welcome. For more information, email Richard Pouzar, firstname.lastname@example.org.
