Small mammals are found throughout Minnesota in various habitats. The six different
habitat sites used for data collection within Itasca State Park includes: burned deciduous,
unburned deciduous, burned red pine, unburned red pine, aspen, and bog.
At each habitat site 40 Sherman traps and eight Longworth traps were used. They were
set up as a 4 x 10 grid with each column having ten Sherman traps and two randomly placed
Longworth traps. The Longworth worth traps were set close to a Sherman trap at a particular
point. Traps were checked for three mornings in a row.
