Determining underlying demographic population processes is fundamental for the management and monitoring of wildlife species (Caughley & Sinclair 1994). Data on demographic processes (fecundity, survival, age of first reproduction, etc.) allow quantification of population trajectories, the identification of population sectors to which growth is most sensitive and determinations of the mechanisms driving population trends (Caswell 2001). In particular, when animal populations have suffered severe declines, demographic data are critical for evaluating what conservation measures might be effective and estimating time to recovery (Beissinger & Westphal 1998). Such information is fundamental to policy debates regarding the viability and benefits of species trade.
