Interactions between timber harvesting and swamp wallabies (Wallabia bicolor): Space use, density and browsing impact

Abstract

Timber harvesting in native Eucalyptus forests was used as an experimental treatment to study its effect on the space use and density of the swamp wallaby (Wallabia bicolor), and on the impact of herbivorous mammals on postharvest tree regeneration. The space use and density studies used a Multiple Before-After Control-Impact (MBACI) design to compare changes before and after (and in some cases before and during) harvesting between unharvested control and harvested impact locations. The impact of harvesting on wallaby space use was quantified separately at two harvested sites in terms of home range size, core range size and overlap (95 and 50% fixed kernels), and the shift in geographic cent..
