Stewartville City Council Addresses Spongy Moth Threat with Federally Funded Management Plan
- Meeting Overview:
During the Stewartville City Council meeting, the most prominent issue discussed was the management of the spongy moth, a pest that poses significant risks to local ecosystems and human health. John Larson from the Minnesota Department of Agriculture and Kimberly Talin Kramers from the Slow the Spread Foundation presented a comprehensive management strategy to mitigate the moth’s impact on Stewartville and neighboring areas, including Rochester and Winona. The program, funded federally, will be implemented in late June to early July, covering approximately 3,200 acres through a method known as “mating disruption.”
Larson outlined the substantial threat posed by the spongy moth, which has been a concern in the United States since the mid-19th century. This forest defoliator prefers over 300 species of trees and shrubs, particularly hardwoods such as oak, aspen, birch, and willow, along with fruit trees like apples. While the moth does not directly kill the trees, its consumption of leaves weakens them, potentially leading to mortality or increased susceptibility to other threats. The pest’s impact is significant, with Wisconsin alone reporting nearly 400,000 acres defoliated in 2023. Larson also highlighted human health risks, particularly from the hair-covered caterpillars, which can cause skin irritation and respiratory issues for asthmatics.
The proposed program aims to disrupt the moth’s mating process rather than kill the moths, using a synthetic pheromone that confuses male moths, preventing successful mating. This method is biodegradable, certified for organic production, and applied using aerial applicators at a low rate, making it nearly invisible to those below. The strategy targets specific life stages of the moth, focusing efforts between the pupal and adult stages. Larson noted that the management program does not impose financial burdens on the city, as it is wholly covered by federal funds.
The meeting also addressed community outreach efforts, including informational postcards and public meetings to keep residents informed about the program. A town hall meeting is scheduled for April 1 at the Civic Center, followed by a virtual town hall on April 7. Notifications about the management activities will be disseminated to council members and local residents.
In addition to pest management, the council discussed infrastructure repairs. A significant project involved the deck repair bid for the Florence Park fishing pier. Two bids were presented: Delore Construction at $12,500 and Dozing and Excavating at $15,750. The council discussed the necessity of these repairs, which involve replacing all eight footings to prevent future shifts due to frost and soil conditions, and the proactive measures being taken to ensure stability.
The meeting also touched upon a detour agreement with the Minnesota Department of Transportation related to the Highway 30 project. The council considered authorizing a resolution to execute a payment agreement for road use during construction, affecting traffic near the airport and golf course area.
The mayor’s report included condolences to families of several community members who had passed away and gratitude towards the Chamber of Commerce for their efforts during Winterfest. The mayor also noted an upcoming Valentine’s Day dinner hosted by the American Legion. Additionally, the city administrator provided updates on preparations for the city’s 250th birthday celebration and ongoing library board discussions regarding a proposed addition to the library.
Reports from various departments concluded the meeting. The public works director reported on the status of the hockey season. Plans for replacing asphalt and updating water meters throughout the city were also mentioned, with approximately 250 of the 1,900 meters updated so far. The fire chief summarized January’s services, noting 65 calls, including 12 fire calls and 53 emergency medical services (EMS) calls, along with a recent promotion within the department.
