    Abstract

    The elusive behaviour of rainforest large vertebrates combined with the inaccessibility of their habitat makes their study challenging (Sollman et al., 2011). Estimations of population size only based on direct observations are therefore infeasible and alternative methods must be used. Since the 1990’s, the use of camera-traps as observer substitute has greatly increased and concerns studies on a wide range of rainforest species or communities (Trolliet et al., 2014) such as the tiger (Karanth, 1995), the puma (Bauer et al., 2005), the ocelot (Trolle and Kéry, 2013), the tapir (Tobler et al., 2013), mammals, (Griffiths and van Schaik, 1993), birds and mammals (Campo et al., 2012), rodents (Nyiramana, 2011). The space which these animals use is also difficult to evaluate as they generally range widely. Consequently, it is hard to estimate population density. Accurate and precise estimates of density are of paramount importance for the identification of wildlife reservoirs on which conservation efforts must focus, as well as the long-term monitoring of these populations to assess conservation action efficiency. This study assesses the current camera-trapping methodology employed by conservationists to estimate density of these populations by studying the impact of study period and choice of statistical method.
