egions, however, pheasant indices were significantly associated with cover indices for Marshall only (r 2 = 0.72; P < 0.01; Figure 2). DISCUSSION We expected a high spring hen population in 2007 given the relatively mild winter of 2007. The overall increase (all study areas combined) in hen indices was heavily influenced by the 121% increase in hens counted in the Glenwood region, where winter severity was mildest (2 periods of deep snow persisting only 2 weeks each). In contrast, winter severity was greatest in the Faribault region (11 weeks of persistent snow), where the hen index declined. Weather during the reproductive period was warmer and drier than average, conditions conducive for increased nest success and chick survival. However, brood size increased only in the Windom region and the brood recruitment index (broods/100 spring hens) was relatively low, especially in the Glenwood region. Our study was not designed to determine cause for changes in population rates, but low recruitment during 2007 may have been a density-dependent response to high pheasant density (Berner 2001). Despite low rates of brood recruitment, total pheasant indices remained high due to above-average carryover of adults from 2006 plus average brood size in 2007. At this early stage in our evaluation, we cannot explain the weak association between summer pheasant indices and habitat abundance (Figure 2). However, preliminary habitat estimates based on GIS coverages of the NWI, WMAs, WPAs, and CRP enrollments appear to have been incomplete, especially on the Glenwood and Faribault study areas. Habitat estimates will be improved as we complete cover mapping. In addition, future analyses of pheasant-habitat associations will use multiple regression models that treat reproductive cover, winter cover, and winter food as independent predictor variables. Our study design called for at least 1 severe winter to estimate pheasant winter cover needs under the full range of Minnesota conditions. We expected pheasant populations to decline following severe winters, with the largest declines on study areas with the least amount of winter cover. However, 5 consecutive mild-moderate winters resulted in relatively high, stable pheasant populations on all study areas. Furthermore, the significant loss of CRP contracts expected during 2007-2009 will preclude an extension of this study. Thus, management implications resulting from this study may be limited to periods of mild-moderate winter weather. We plan to complete annual cover mapping of all 36 study areas in 2008. Next, we will attempt to build a multiple regression model using data extracted from a previous pheasant habitat study (Haroldson et al. 2006) and test the model with data from this study. Finally, we will assess winter habitat availability in relation to snow depth and drifting during the next moderate-severe winter. ACKNOWLEDGMENTS We thank C. Jergenson, K. Hubert, R. Kelsey, M.
