Field Trips
The 2025 MISAC field trip was co-hosted by Three Rivers Park District and the MISAC Field Trip Committee at Baker Park Reserve and Lake Rebecca Park Reserve, west of Minneapolis. Participants traveled to a number of sites within those reserves and heard from experts on topics including: jumping worms (including identification and mulch management); invasive species, deer management and forest restoration; climate ready woodlands; AIS prevention through behavior change; and woody invasive species management.
The 2023 MISAC invasive species field trip was hosted by the Wild Rivers Conservancy and the St. Croix National Scenic Riverway on the beautiful Saint Croix River. Attendees paddled seven miles from MN Interstate State Park Landing to Osceola Landing. Along the way, participants learned about various invasive species projects going on in the Riverway, including a purple loosestrife biocontrol program, yellow iris management on the upper Namakagon River, non-native phragmites in the watershed, ongoing zebra mussel monitoring throughout the Riverway, and buckthorn removal on Peaselee Island.
The 2022 MISAC invasive species field trip visited the St. Louis River Estuary in Duluth. Attendees had the opportunity to learn about invasive species in the estuary (including knapweeds, non-native honeysuckle, tansy, yellow iris, purple loosestrife, Eurasian ruffe and more) and their thoughtful management, preparing for impacts to ash trees from emerald ash borer, restoration of wild rice, care for sturgeon populations, and tribal member perspectives on invasive species and relationships with nature more broadly.
