The presence, condition, and numbers of the types of fish, insects, algae,
plants and other aquatic life can provide accurate information about the
health of a specific waterbody such as a river, stream, lake, wetland, estuary
or coral reef. <more>
For EPA's Report on the
Environment, an indicator is a numeric value derived from actual
measurements of apressure, state or ambient condition over a specified
geographic domain, whose trends over time represent or draw attention
to underlying trends in the condition of the environment. Key indicator
criteria are:
the indicator is useful
the indicator is objective
the indicator is transparent and reproducible
the underlying data is characterized by sound collection methodologies,
data management systems to protect its integrity, and quality
assurance procedures
data are available to describe changes or trends
the data are comparable across time and space, and representative
of the target population.
Therefore, biological indicators are defined here
as a numerical value(s) derived from actual measurements, has known
statistical properties, and conveys useful information for environmental
decision making. It can be a measure, an index of measures, or a
model that characterizes an ecosystem or one of its critical components.
The primary uses of an indicator are to characterize current status
and to track or predict significant change. With a foundation of
diagnostic research, an
ecological indicator may also be used to identify major ecosystem
stress.
