| Abstract | are managed in three systems in Tamil Nadu namely, private, Hindu templesand forest department. We studied the population size and structure, natality and mortality during 2003-05 in the threesystems to assess their long-term viability. The population in the three systems totalled 133 individuals in 2005 withadult class constituting over 75% of the population. Sex ratio of the population was biased towards females in privateestablishments (male to female 1:10) and temples (1:21), but male biased in the forest department (1:0.5) with adultmales constituting 50% of the total population. There was no breeding in private and temple populations. In the forestdepartment population, fecundity has dropped (0.065/adult female/year) over the past 10 years (1996-2005) comparedto an earlier (1969-1989) estimate (0.155/adult female/year). Mean mortality estimated together for the three systemsis higher (3.9%) than reported earlier (1.9%). Given the aging population trends and with no breeding and fewerchances of additions from the forest department due to ban on elephant sale, captive populations in private establishmentsand temples may not survive in the long run. Sustainability appears rather remote for population of the forest departmentsystem with a male bias, increase in mortality and a decrease in fecundity. |
