This paper reviews some of the important methods for estimating animal numbers or densities based on (i) direct counts of population units as used in quadrat, strip, line‐transect and line‐intercept sampling and (ii) indirect counts and indices, such as capture‐mark recapture, change‐in‐ratio, catch‐effort methods and indices based on track counts, call, roadside and pellet‐group counts, etc.
