A section of the Upper Twin Springs Trail in Decorah is scheduled to close while crews remove and treat invasive plants later this week.
According to a Monday, Oct. 26, 2026, press release from Decorah Parks and Recreation, Japanese barberry and buckthorn will be cut and their stumps treated with glyphosate on Wednesday, Oct. 28, and Thursday, Oct. 29, if conditions permit. The work will take place at the trail’s southeast corner.

The affected areas will remain closed through the required re-entry period, which is 24 hours after the application. Signs will stay posted for 96 hours and will include additional information about the treatment.
Residents and trail users should follow the closure signs while the work is underway and during the re-entry period. Parks and Recreation listed Marc Holtey, parks and recreation director, as the press contact and provided the department’s phone number, 563-382-4158.
