Abstract
Izoceño hunters from 22 communities in the Bolivian Chaco voluntarily recorded data on over 5000 captured animals between 1997 and 2000. This paper presents and assesses the quality of biological information derived from hunter self-monitoring records. The nine most commonly hunted mammals were four ungulates ( Mazama gouazoubira, Tayassu tajacu, Tayassu pecari, and Tapirus terrestris) and five armadillos ( Dasypus novemcinctus, Tolypeutes matacus, Euphractus sexcinctus, Chaetophractus villosus, and C. vellerosus). The lack of quantitative precision restricts data analysis to qualitative assessment and relative comparisons among or within species. The data indicate seasonal reproductive activity (pregnancy rates, proportion of females and/or juveniles hunted) for all species except T. terrestris. The data also suggest that most species shift activity patterns during the coldest season of the year to increase day-time or mid-afternoon activity. Self-monitoring as conducted in the Izozog is not adequate for analyses of condition or habitat preferences.
