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

摘要: Abstract Timber harvesting in native Eucalyptus forests was used as an experimental treatment to study its effect on the space use and density of swamp wallaby ( Wallabia bicolor ), impact herbivorous mammals postharvest tree regeneration. The studies a Multiple Before–After Control-Impact (MBACI) design compare changes before after (and some cases during) between unharvested control harvested locations. quantified separately at two sites terms home range size, core size overlap (95 50% fixed kernels), shift geographic centre location (GCL). most obvious response substantial position and, cases, large (>100%) increase size. Relative controls, GCLs shifted substantially farther one site but not other. Home tended be similar indicating that had minimal overall space. One year harvesting, about five times greater than sites. This characterised by almost complete abandonment areas for first 8–10 months then rapid influx animals this time. Browsing 12-month-old seedlings (% biomass removed) ranged from 1.0 11.2% insubstantial coppice (0.4–0.9%). percentage severely damaged 0 12.9%. reduction stocking attributable severe browsing 3% little regeneration success. results are discussed with reference effective monitoring commercially forests.
