Use selective or reduced impact logging instead of conventional logging
A review in 2014 of 41 logging studies in the Neotropics (Bicknell et al 2014) found that reduced impact logging had a smaller effect on bat abundance than conventional logging, even when conventional logging used similar harvesting intensities as reduced impact logging (≤30 m3/ha). The average effect sizes were lower for reduced impact logging than for conventional logging (data reported as statistical model results). Effect sizes were calculated from a meta-analysis of all available studies (n = 41) and included multiple species-level comparisons for each logging method (reduced impact logging: 88 comparisons, all conventional logging: 139 comparisons; conventional logging with harvesting intensity ≤30 m3/ha; 84 comparisons). All 41 studies used selective logging alongside other interventions typical of reduced-impact logging such as directional felling, winching of logs and careful planning of logging roads.
