Occurrence of log-dwelling invertebrates in regeneration and old-growth wet sclerophyll forest in southern Tasmania

A list of colcopteran, large collembolan, centipede, miilipede and molluscan specics associated with rotting logs was compiled for an old-growth Eucalyptus obliqua wet sclerophyll forest and adjacent 19- year-old regeneration in southern Tasmania. A total of 67 species were found, 40 occurring in both areas, 53 in old-growth forest and 54 in the regenerated area. Of the species found in only one of the areas, nearly all occured in one or two samples only, so no conclusion about their absence from the other area can be made. Two rarely collected species of beetles were recorded only in the old growth forest. Conservation of log-dwelling invertebrates in production forests is discussed.
