Summary

Twelve of 12 (100%) high blocks, 18 of 52 (35%) moderate blocks, 31 of 122 (25%) low blocks, and 10 of 59 (17%) very low blocks were surveyed. The uncorrected moosepop estimate was 1175 ± 152 (90% Confidence Interval [CI]), the estimated bull/cow ratio was 44 ± 9.9 bulls per 100 cows and the estimated calf/cow ratio was 12 ± 2.7 calves per 100 cows. The uncorrected moose density estimate was 0.20 ± 0.026 moose per km2. When corrected for sightability (SCF = 1.20) the estimated moose density was 0.24 ± 0.033 moose per km2.

A portion of Management Unit 7-42 has previously been surveyed in 2001, 1993, and 1989. All previous surveys covered the MU 7-42 area south of the Prophet River. In 2001 the uncorrected moose density was 0.75 ± 0.12 moose per km2, the bull/cow ratio was 25 ± 7.4 bulls per 100 cows and the calf/cow ratio was 18 ± 3.5 calves per 100 cows. For direct comparison to previous surveys, 2015 moose population metrics were calculated for the MU 7-42 area south of the Prophet River. The uncorrected moose population density decreased 70% from 2001 to 2015, this change was statistically significant.
