Seasonal home ranges were estimated for 10 Moose (three males and seven females) during sum- mer 1987, 13 Moose (three males and 10 females) during autumn 1987, and for 11 Moose (three males and eight females) during summer 1988 (Miller 1989). There was no correlation between the size of seasonal home ranges and the distance between the nearest lick and seasonal centers of activity home ranges (x^ = , P = ). However, all Moose, except four females (whose centers of activity were < km to the nearest lick), had elongated home ranges during summer and/or autumn that encom- passed at least one lick (Figure 2). All home ranges converged on the area that contained the licks. Discussion Moose in our study area used roadside licks in spite of an availability of ponds that contained aquat- ic plants. The average distance to a potential aquatic feeding site (any beaver flowage, lake, or slow mov- ing river) from each telemetry location of Moose was 783 m (range = 652-960 m. Miller 1989). Although aquatic plants contain high amounts of sodium in comparison to terrestrial plants (Botkin et al. 1973; Fraser et al. 1984; Crossley 1985), the use of licks may be advantageous because licks may pro- vide a more efficient means of obtaining sodium or other minerals than aquatic plants. Belovsky (1978) calculated that a Moose at a lick ingested sodium 15 times faster than at an aquatic feeding site. Also, aquatic plants have a lower energy content than ter-.
