1 <br />' As can be seen in Table 2, the majority of trapping was done with clover <br /> traps. Trap success ranged from 18~ to 78%. Trap success was dependent on <br />' many things but predominantly on time of year, trap location relative to elk <br /> use areas, and bait. Early winter proved to be the most successful period for <br />' trapping. The disadvantage to winter trapping was that it was impossible to <br />predict where these animals would calve and summer. As a result, trapping <br />efforts were later conducted on summer range in order to collar more elk using <br />the areas of interest. <br />' Monitoring <br />' Ground and aerial surveys between January 1, 1981 and July 31, 1985 <br />yielded 3,961 locations of 64 transmittered elk (Table 4, Monthly Summary of <br />Transmittered Elk Locations and Table 5, Yearly Summary of Transmittered Elk <br />' Locations). During the same period, 79 conventionally collared elk have been <br />located less than 350 times and 142 ear tagged elk less than 100 times (where <br />' individual could be identified). A significant portion of these locations are <br />capture and harvest sites. Compared to ratio transmittered elk, conver~- <br />' tionally collared elk have yielded little data in terms of effort expended. <br />All locations prior to July 31, 1984, are found in maps and tables of the <br />' previous 4 annual reports. During the past year (August 1, 1984 - July 31, <br />1985), 38 transmittered elk have been located a total of 724 times. Locations <br />of 20 of these elk were mapped (Maps 1-16). Eighteen elk with transmitters <br />' were not mapped due to early mortality or transmitter failure (Table 6, Trans- <br />mitter Collared Elk Locations Not Mapped). There were also 10 locations of <br />' conventionally collared elk and 8 locations of ear tagged elk (Table 7, Ear <br />Tagged and Conventional Collared Elk Sightings). <br />' Mortality <br />' During the current reporting period (August 1, 1984 to July 31, 1985), 18 <br />transmitters were lost. Twelve (12) of these are attributed to mortalities <br />and 6 to transmitter failure or loss (Table 8, Mortality and Fate of Radio <br />Transmitters on Cow Elk). This brings the total losses attributed to mor- <br />tality to 31 of 64 transmittered elk. The overall yearly mortality for the 4 <br />years from September 1, 1981 - July 31, 1985 averaged 22Y (Table 8). A break- <br />down of mortality indicates a fairly even distribution between legal harvest, <br />-8- <br />
