found between elk using mine or control areas. There has been no indication that elk are abandoning mine areas. There continues to be extensive use by elk within a quarter mile radius of active mining operations. In fact, same calving home activity centers are within a quarter mile of active mining. Statistical analysis indicates that all of the above hypotheses must be accepted; no statistically significant differences could be found. None of the anticipated impacts could be documented. The results of this study are very similar to those found by Kuck (1984) "Impacts of Phosphate Mining on Mule Deer, Elk and Moose in Southeast Idaho". There are a number of close similarities between the two studies that make them very compariable. These similarities include habitat type, home range size, fidelity, and habitat utilization and selection patterns, during the calving period. The Idaho study involved 4.5 years of extensive radio telemetry work on deer, elk and moose, as well as pellet group count data. Kuck (1984) could find no evidence that deer, elk or moose were being displaced from areas adjacent to mines. In addition, an experiment was conducted involving the direct human disturbance and simulated mine noises upon transmittered deer and newly born elk calves. The study reports that home range size and habitat utilization patterns for deer subjected to these treatments were not significantly different from control deer. However, there were significant influences upon elk calves. Elk calves subjected to these treatments moved significantly greater distances and had much larger home range sizes than control elk. Elk calves also showed some variations in habitat utilization patterns. However, as pointed out in the Idaho study, the treatments tested resulted in human harassment much more severe than encountered during mining. In spite of the influence .of these treatments on elk calves, there was no resulting increase in mortality which was monitored through the first winter. Results suggested that effects of disturbance during the calving period may be less important than other factors. It is suggested that such factors as nutritional plane of the mother may be more important. In conclusion, our data indicates that mining and its associated forms of surface disturbance (at CYCC and the surrounding surface coal mines) within documented elk calving home ranges appears to have no measurable negative impact 11
