摘要：Long term monitoring of an entire biological community is rarely undertaken as identifying
all species in a community is time consuming, expensive and requires specialised expertise.
For this reason the use of indicator species is often suggested as a means to monitor the
health of an ecosystem and to act as surrogates for the entire community. The identification of
appropriate indicator species can be difficult and frequently requires some prior knowledge of
the system to be monitored and some background information on the species that occur there.
Before suitable indicator species can be identified the particular attribute of the environment
to be monitored needs to be defined as this will determine what species or suite of species are
chosen as indicators. For example, indicator species can be used to monitor long-term change
in habitat composition or water quality.
