CUMULATIVE LOCATIONS (NO.) 



Fig. 1. Actual plotting of cumulative locations versus cumulative home-range 

 area; note curves for defined (Doe No. 12) and undefined (Doe No. 21) home 

 range. A home range is defined only when additional locations do not increase 

 its area. 



Triangulation was made difficult by the rugged topography of the 

 study area. Deflection of signals from mountainsides frequently resulted 

 in inaccurate bearings. The accuracy of bearings was ±7.5° at 2.5 km, 

 and the average of the error polygons was 50 ha at that distance. In a 

 Minnesota study, accuracy of bearings ranged from to 40° (Mooty et 

 al. 1987). Most (>70%) of our locations were estimated from bearings 

 taken <2.5 km from the animal. Poor roads and rugged topography 

 hindered movement from one spot to the next while bearings were being 

 taken, and some animals moved before locations could be pinpointed.
