Cost of the presentation is $10 per person and registration is required.

Join Trout Unlimited (TU) and the Minnesota Department of Natural Resources (DNR) for a volunteer work day at the DNR Vermillion River Aquatic Management Area to clear invasive species from the banks of the South Branch, one of the Vermillion River’s trout streams. While anyone is welcome to work, a core group of TU volunteers, the Vermillion Riverkeepers, has been clearing invasive species and restoring this great prospective fishing destination for the past few years, donating hundreds of hours to the project. Volunteers will meet at the property, which is west of Hwy. 52 near 200th St. E. (Co. Rd. 66) on Saturday, October 29, 2016, at 9 a.m. After battling the buckthorn (and other invasive plants), volunteers will be provided lunch. To register for the event, contact TU habitat restoration chair Tony Nelson, who will send out an email before the event providing details on what to wear and what to bring.

Join the Twin Cities Trout Unlimited (TCTU) Vermillion Riverkeepers for its last volunteer work day of the year! Volunteers will cut and haul away invasive buckthorn from the banks of the Vermillion River’s South Branch on Saturday, Dec. 3, 10 a.m. – 1 p.m. The group meets at the Minnesota Department of Natural Resources (DNR) Vermillion River Aquatic Management Area (AMA) at E. 200th St. at U.S. Hwy. 52 in Vermillion Township. The Vermillion Riverkeepers, now 55 members strong, plan to help re-establish native prairie, stabilize banks to reduce erosion, and restore wildlife habitat on the South Branch site. All community members are welcome to help shoulder the work, enjoy the great company, and have lunch. Please register by Thursday, December 1, by contacting Tony Nelson, if you plan to attend, to ensure TCTU has enough food and gear for every volunteer.
