As in the terrestrial environment, most data collection from
freshwater habitats to date falls into the survey, surveillance or
research categories. The critical difference between these
exercises and a monitoring project is that a monitoring project
will clearly identify when we need to make a management response. A
Model for Conservation Management and Monitoring Monitoring (as
defined by Hellawell) is essentially a tool of practical
conservation management, and Fig. 1.1 shows a simple, but
effective, model for nature conser- tion management and monitoring.
The need for clear decision-making is implicit in this model. First
we must decide what would represent a favourable state for the key
habitat or species, and then we must decide when to intervene if
the state is (or becomes) unfavourable. A third, often overlooked,
but equally important, decision concerns when we would consider the
habitat or species to have recovered; this is unlikely to be the
same point that we became concerned about it. This decision not
only has resource imp- cations, it can also have major implications
for other habitats and species (prey species are an obvious
example). All of these decisions are essential to the devel- ment
of an efficient and effective monitoring project.
