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.
