1 the area of general observations extend as far as 20* miles from the mine ' covering the movements of elk tagged on the mine. The specific location of the LMCT can be found on the enclosed maps showing elk movements. Amore detailed description of the area is found in the 1985 Completion Report. ' METHODS No trapping was done during this period. Monitoring was done primarily with ' fixed wing aircraft to locate transmittered animals. Helicopter classification surveys were conducted to determine elk productivity. ' Calving home ranges were determined using Mohr's (1947) minimum convex polygon method. Calving home range fidelity was compared by examining amount of overlap between home ranges in consecutive years and by comparing distance between year to year calving home range activity centers ("ariti~metic mean center", Dixon and Chapman, 1980; "geometric center", kl 1975 H bi li i V d d b l h anWin e, ). tat uti zation was eterm a ne y ca culating t e percentage of transmittered elk locations within each vegetation type. ' Details for all of the above methods are given in the 1985 Completion Report. ' RESULTS t Monitoring ' Monitoring between August 1,1986 and July 31, 1987 of 18 transmittered elk yielded 253 locations (Table 1, Monthly Summary of Transmittered Elk Locations, and Table 2, Yearly Summary of Transmittered Elk Locations). ' Locations of 12 of these elk have been mapped (Tables 13 - 24 and associated maps). Six elk with transmitters were not mapped due to early mortality or ' transmitter failure (Table 12). There were also fourteen locations of conventionally collared, ear tagged and previously failed transmitter ' collared elk (Tables 1 and 11). ' Mortality During the current reporting period (August 1, 1986 to July 31, 1987) six ' transmitters were lost or failed. Two of these are attributed to mortalities and four to transmitter failure (Table 3, Mortality and Fate of ' -2- 1
