Planting design at the Schottler Wildlife Management Area (WMA) south of Austin, Minnesota in Mower county, SE Minnesota. CSG = cool season grass dominated fields, WSG = warm season grass dominated fields, F = forb fields lacking cup plant and compass plant, and TF = forb fields characterized by the presence of cup plant and compass plant. Both TF and F has greater than 65% forbs by rooted abundance. Each plot was approximately 11 acres in size. Study utilized approximately half of the total WMA area. Plots inside the yellow boundary were used for small mammal surveys. Photo Credit: Google Earth.

Total unique captures for key species within the grassland reconstructions at the Schottler Wildlife Management Area south of Austin, Minnesota. Only species with a minimum of 10 captures within a year were included. CSG = cool season grass dominated fields, WSG = warm season grass dominated fields, F = forb fields lacking cup plant and compass plant, and TF = forb fields characterized by the presence of cup plant and compass plant.
