Camera traps and activity signs to estimate wild boar density and derive abundance indices

Abstract

PAIs based on number of wild boar trails and on camera trap data appear to be more sensitive to changes in population size than PAIs based on signs of rooting. For wild boar densities similar to those recorded in this study, nine camera traps per km² are sufficient to estimate the mean density of wild boar. © 2017 Crown copyright.
