^aUpper bound of appropriate management level (AML).

^bLower bound of appropriate management level.

NOTE: The following Herd Management Aeas (HMAs) were removed from Table E-1: All HMAs with zero animals, AMLs of zero, or both; all HMAs with mixed burros and horses; and all burro-only HMAs. All remaining HMAs were numerically ordered by most recent population-size estimate. All HMAs with fewer than 50 horses were excluded. Every third HMA was systematically selected, resulting in 36 HMAs. Four additional HMAs that were used in Eberhardt et al. (1982) and Garrott et al. (1991a) were added to total 40 HMAs sampled.
