A group of natural resources experts are teaming up to offer a variety of field trips July 11-12 to the prairies of northwestern Minnesota.
Leading the tours will be the Minnesota County Biological Survey, the Natural Sciences Department at the University of Minnesota-Crookston and the Minnesota Native Plant Society.
According to trip coordinator Nancy Sather, an MCBS ecologist originally from Fosston, Minn., northwestern Minnesota's tallgrass aspen parkland is too diverse to be explored on a single trip. As a result, a variety of shorter mix-and-match tours are planned to enable people to choose the experience that best matches their interests and schedules as well as the level of difficulty of the trip.
The level of difficulty is based on a combination of the distance covered and ruggedness of the terrain.
Participants can choose from among the following tours.
