et al 1999b), although in some situations it may reflect a real difference in the response of the
diatom and macrophyte communities to the prevailing trophic conditions, such as a difference
in the time taken to respond to nutrient reduction measures (Box 1). The use of both methods
has the advantage that a broader spectrum of the flora can be examined for the impact of nutrient
inputs in sensitive areas, allowing judgements to be made on more comprehensive environmental
information. However, the information gained from either method should not be used in isolation
and should be put into context in the light of all information gathered at a site. It is likely that
chemical data and physical habitat description will add valuable information to assist
interpretation. The points listed in Box 1 should also be borne in mind.
