aStudy areas denoted with an asterisk (*) are in the aspen parkland, all others are in the prairie.
bA single track search was conducted during May or late June. Values in parenthesis are estimated percentages of searched quarter sections in which tracks would have been found had two searches been conducted and are based on correlations of data from twice-searched study areas.
cNo data available.
