About this book
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 can be used to assess the prevailing chemistry of a water body. This book describes the method that can be used for this analysis, especially for forest streams in upland areas. Forestry Commission Field Book No.13.
