A replicated experiment was done in plots in a stand of reed (Phragmites australis) which were cut, burnt or left unmanaged. Invertebrates in the soil were sampled by heat extraction and hand-sorting, and those above ground by water traps, dissection of reed stems and in situ counting. Only a few families showed differences between treatments, and this number declined with time after treatment. After 1 year, no soil invertebrates and only a few families of above-ground invertebrates showed any significant treatment effects. Most treatment effects were between the unmanaged control and both cut and burnt plots. A significant difference between cut and burnt treatments was recorded for only one family, with numbers lower in the cut plots. Total number of invertebrates, species-richness, species diversity and evenness showed no relationship with treatment. Many soil invertebrates were more abundant in drier parts of the reed bed, but there was no similar effect on above-ground invertebrates. [ABSTRACT FROM AUTHOR] |
