ABSTRACT Mammalian communities living in tropical forests, particularly those ecological transition zones, are under constant threat from human activities. In many regions, baseline data on mammal richness, occupancy, detection probability and the environmental factors that influence these metrics lacking. As a key metric for guiding conservation decisions, species richness can be underestimated due to varying probabilities, leading being overlooked. Advances technology methodology have revolutionised wildlife monitoring, fostering increase of multi‐species occupancy models (MSOMs) efficient studies community, shifting focus single entire communities. MSOMs, hierarchical share information across via random effects, address imperfect provide accurate unbiased estimates. To fill this gap, we used cameras trap Mpem Djim National Park, Central Cameroun. We generalised linear model selection approach evaluate affecting events. Similarly, MSOMs within Bayesian framework our initial estimate at each camera location understand covariates 19 vertebrates recorded area inform management decisions species. From 915 independent photographic events obtained over 1700 days capture, study results highlight importance habitat, distance river, normalised difference vegetation index topographic position (TPI) explaining patterns found forest (GLM: B 0.31, IRR 1.36, CI 0.14–0.48, p < 0.001), NDVI 0.21–0.41, 0.001) TPI 0.17, 1.19, 0.08–0.26, were positively associated with events, whereas river −0,19, 0.83, 0.0.27 (−0.11), was negatively However, mean community 0.33 ± 0.10 [2.5%–97.5% CI: 0.54], while 0.07 0.02 [2.5%–95% 0.04, 0.12], indicating that, average, approximately 33% sites likely occupied by interest, 7% sites.
