It was later found and tagged by a hunter with a cow permit. <br />d These two transmitters are presumed illegal harvest because transmission ceased unexpectedly during the fall <br />hunting season. One was less than one year old, the other was less than two years old. <br />e Two of these are presumed transmitter malfunctions because transmission ceased unexpectedly during the spring <br />(one in April and one in June). Both transmitters were between 15 and 18 months old. <br />f Beginning 9/1/84, there were 36 working transmitters. In addition, one elk with a failed transmitter was <br />harvested and another elk with a failed transmitter was sighted so different beginning totals are used. 38 <br />transmitters were used to calculate mortality and 36 transmitters were used to calculate transmitter failure and <br />loss. <br />9 All of these transmitters are presumed illegal harvest because. they ceased transmission during the hunt and all <br />were less than 2 years old. <br />h One of these transmitters disappeared in the fall and was possibly poached but was approximately 31 months old <br />so failure was assumed. <br />~ Total Attrition percentage was calculated by taking Total Mortality % + Transmitter Failure % + Lost Transmitter <br />% = Total Attrition %. <br />-64- <br />
