Project summary:
Land snails, landhoppers, millipedes and carabid beetles were collected from surface litter on six plots in mature forest and six plots in ca. 25 year-old regrowth forest at each of two sites near Tahune Bridge on the Huon River. Of the 918 specimens systematically collected, 884 were referred to nine beetle, 13 snail and 19 millipede species. Four carabid and four snail species, represented by only 14 specimens in total, were found in mature forest but not in regrowth.
One millipede species was much less abundant in regrowth than in mature forest, but only at one of its two sites of occurrence. High plot-to-plot and site-to-site variability, coupled with low harvests of most species, make it difficult to conclude with confidence that any of the species collected was disadvantaged by logging and regeneration. For the more abundant species, it seems safe to conclude that populations in regrowth are comparable to those in nearby mature forest.
Methodology: Surface litter analysed at two sites (Tahune Bridge and Huon River) each of which had six plots in both mature forest and 25 year-old regrowth. Each plot was 5×15 m and was searched for about 125 minutes.
Datasets: None available.
