“…These findings (e.g., ASPT/BMWP scores, BOD, ammonium) are consistent with other studies on the effects of livestock farming on water quality in the U.K. (e.g., Schofield et al, 1990;McCahon et al, 1991;Rutt et al, 1993). In arable and livestock farms with no point-sourced inputs of organic effluents/waste, the ASPT scores are generally above 5, indicating good water quality in terms of a healthy and diverse community of invertebrates (Yorke, 1994), as seen in the Killoch stream.…”

Runoff from intensive dairy farming systems can impair the quality of catchment waters, with potential ecological and human health implications. A water quality study was carried out in three streams in a predominantly dairy farming region, with the aim of assessing the effects of diffused-and point-sourced inputs on a number of water quality parameters and benthic macroinvertebrates. The results showed significant increases in streamwater biochemical oxygen demand (BOD), ammonium-nitrogen (m-N) and molybdate reactive phosphorus (MRP) concentrations between the farm reaches. These changes in water quality appeared to be due largely to the point-sourced inputs from farmyards, and had a significant effect on the ability of the water to support a healthy and diverse community of invertebrates. The results also showed that concentrations of dissolved oxygen (DO) and ammonium in streamwater were the two most important parameters studied that were inversely related to the invertebrate scores.

“…Species-level identification is therefore difficult for low-cost, rapid assessment of Australian rivers. Some authors have questioned whether the environmental requirements of particular groups of freshwater invertebrates can be generalized at taxonomic levels above species (Resh & Unzicker 1975;Campbell 1981;Cranston 1990), However, when whole communities are considered, discrimination between sites using classification and ordination can be as effective, or nearly as effective, at the family level as at the species level (Furse et al 1984;Marchant 1990;Rutt et al 1993), Family-level studies of river macroinvertebrates have been used successfully for such purposes as describing biogeographical pattems across large areas (Corkum 1989) and assessing responses to regulation (Armitage et al 1987),…”

This paper describes a simple and inexpensive procedure for the rapid biological assessment of water quality in rivers and streams in eastern Australia. The procedure involves the standardized collection of samples of 100 macroinvertebrates from defined habitat types within a water body. Specimens are identified to family level only and a biotic index is calculated. Proposed future testing and evaluation are described, and the limitations of the rapid approach are discussed.

“…to Stream macroinvertebrate communities have shown that the differences between samples are not as clear at the family level as at the species level (Edward et al, 1987;Marchant 1990), although the differences between the two levels may be small (Furse et al, 1984;Rutt et al, 1993). In the marine environment, several studies have established that species-level identification is not essential for biological assessment (Warwick 1993).…”

Benthic macroinvertebrates were sampled from four sites on upland streams in the Wentworth Ealls area of the Blue Mountains, NSW. One site received effluent from a sewage treatment plant and the others were reference sites. Eive replicate collections were taken from each site on four occasions at intervals of 3 months. Macroinvertebrate community data were analysed using univariate (ANOVA) and multivariate (NMDS) techniques and comparisons were made between analyses at different levels of taxonomic aggregation and using different methods of data transformation. Similar pattems were observed at both species and family levels, and even the order level showed a clear community response to effluent input. Binary (presence/ absence) data provided similar results to quantitative data for the species and family levels. However, when binary data were used at the order level, the distinctions between the reference sites became blurred. We discuss the implications of these findings for environmental monitoring.
