The off-takes calculated in Tables 4 and 5 assume that removal occurs prior to the animals reproducing in 2002 and are based on the estimated numbers of donkeys and horses on each property at the start of 2002. If removal does not occur prior to the animals reproducing than the estimated starting population needs to be increased by the appropriate rate of increase for that species.
