A variety of stream habitats is also essential
to satisfy needs of an individual species during
different stages of its life cycle. The
illustration of a typical smallmouth bass life
cycle (shown on the left) demonstrates how habitat
needs shift from spawning to adult life stages.
Management decisions that prescribe river
conditions to favor only one life stage, such as
adult smallmouth bass, do not sustain the resource.
If we do not adequately consider the diverse
habitat needs of a species throughout its entire
life cycle, we may contribute to, if not cause, a
population to crash.
