Population Projections<br />

A population projection for a stable age<br />

distribution of the one <strong>horned</strong> rhinoceros<br />

in captivity in <strong>Indian</strong> zoos was generated<br />

using PM2000. It was assumed that for<br />

ensuring a genetically viable and<br />

demographically stable population an<br />

increase in the population from the<br />

current 47 specimens to 100 over the<br />

next 10 years would be required. For a<br />

stable population a steady decline is<br />

observed in figure 6 while the actual population shows an exponential increase over<br />

the next 10 years and then stabilizes at 100 individuals for the next 40 years. Details<br />

of the number of individuals required for a stable population are presented in table<br />

13. The first row # Born – represents the number of births required each year to<br />

achieve a stable population.<br />
