- Sampling effort is expressed as the number of randomly located 30-km survey transects needed to attain the desired power of 1-β = 0.80 for each hypothetical scenario. Separate estimates of sampling effort are also given for areas with different combinations of classes of guanaco relative abundance and type of guanaco group. Estimates are also given after pooling all classes of relative abundance.
