Abstract: Objectives Evaluate the effectiveness of three methods to classify elk in the central valley. The methods are: 1. Old technique developed by Martinka (1969). 2. Utilization of Martinka's transects but done with every transect being classified each day for 7 days. 3. Helicopter classification with three counters. Findings and Status Helicopter counts appear to provide the best data. Ground counts performed in the past may have overestimated the bull/cow ratios and underestimated the calf/cow ratios.

| ABSTRACT | Objectives
Evaluate the effectiveness of three methods to classify elk in the central valley. The methods are:
1. Old technique developed by Martinka (1969).
2. Utilization of Martinka's transects but done with every transect being classified each day for 7 days.
3. Helicopter classification with three counters.
Findings and Status
Helicopter counts appear to provide the best data. Ground counts performed in the past may have overestimated the bull/cow ratios and underestimated the calf/cow ratios. |
