Field Book
G.S Patterson, B.R.S. Morrison
Studies in the UK and elsewhere have shown that acid freshwater habitats have different floras and faunas and fewer species in most taxonomic groups, when compared with near-neutral waters. The presence or absence of certain common species that are sensitive to acid waters can be used to assess the prevailing chemistry of a water body. The method described in this Field Book enables managers to do this for forest streams in upland areas using a limited number of readily recognised invertebrate animals. It may also be used for streams outside woodland. The method is suitable for qualitative monitoring over a number of years to show trends in the ecological status of selected streams. This publication is still available in hard copy.
