AbstractWhile habitat loss and hunting remain the major drivers of biodiversity declines, sublethal disturbances, such as human presence, recreation, and noise also impact wildlife. In response, wildlife often adjust their spatiotemporal behaviors. This study assesses how terrestrial wildlife responds to sublethal disturbances associated with sustainable logging activities. Using camera traps, we conducted a 2‐year continuous survey of two logging compartments within an active, sustainably logged forest reserve in central Sabah, Malaysian Borneo. The survey encompassed periods before, during, and after logging activities, and we obtained daily felling data. Using generalized linear mixed models, we assessed the impact of logging on the spatiotemporal activity of 10 terrestrial mammal and galliform species, considering spatial factors like logging intensity and distance from logging activity, and temporal factors such as days since logging. Four species had a significant and strong response to logging intensity, with varied directions of effect. Only for one species, the response to logging intensity was mediated by time since logging. Though only descriptive, we found no evidence of diel activity shifts, and, for all other species detected during our survey, general patterns in the number of records across each logging period were mixed. Our results highlight the variable and species‐specific responses to logging activity. At a local scale, many species exhibit resilience in their spatiotemporal activity patterns, but for affected species, the effects of logging appear to linger over time. The overall limited response could be due to the relatively low disturbance nature of reduced‐impact logging.
