Managing Woody Debris - FreshwaterLife

Benefits
Why is it
Important?
The rôle of woody
debris in the healthy
functioning of
freshwater
ecosystems has
become increasingly
recognised in
research carried out
in different parts of
the world since the
1980s. LWD is
beneficial in some of
the following ways…
Steep wooded Steep banks wooded provide banks the best provide conditions the for best the

of woody debris.
The backbone of the watercourse
Stabilises river
banks and beds
LWD can be seen as the
‘backbone’ of the
watercourse; its presence
can help protect a stream
from the erosion of beds
and banks by resisting and
deflecting flows. It also
assists with the trapping
and retention of sediments,
organic matter and CWD.
Increases floodwater storage
Woody debris helps regulate the energy of running water by decreasing the velocity.
Thus the ‘travel time’ of water across the catchment is increased.
