How to restore headwater streams in a
eco-hydro-sociologically sustainable way?
Forest drainage
impairs stream
ecosystems via
excessive
sedimentation
degrading ecological
status and natural
functions.
Visible restoration
benefits help in
setting restoration
targets and creating
effective plans with
strong public and
stakeholder
support.
Aquatic mosses
are key to
recovery of boreal
stream
biodiversity.
Sedimentation
may cause trophic
cascade by
obscuring the
predation effects
on ecosystem
functions.
Restoration
structures enhance
stream biodiversity
but responses are
taxon-specific and
slow to emerge.
This poster highlights work from ReFFECT-project (Effectiveness of
restoration of sediment-stressed forest streams - Ecology meets
hydrology) funded by Academy of Finland in 2012–2016. The research is an
ongoing joint effort by ecologists, hydrologists and socioeconomists
establishing mechanistic linkages between anthropogenic impacts in streams
and their hydrological and biological responses in a societal context.
In-stream
restoration that
increases hydraulic
retention has
positive
biodiversity effects
extending beyond
stream channel.
