The Fine Art of Restoring Aquatic Ecosystems
Lakes and wetlands, ecologically impaired to different degrees by pollution and exploitation are a sad
reality not only in Europe, but around the globe.
But wait: Ecological restoration of these ecosystems is possible!
Sven Björk,
the pioneer and long-time
practitioner of ecological lake restoration describes well-illustrated, practical examples (before and
after) of the restoration of different types of damaged aquatic ecosystems and discusses tailor-made
approaches to rehabilitate their individual ecological structure and functions. The crucial importance
of the relationship between catchment area and the associated
lake/wetfond
in
selecting the "right" ap¬
proach and thus successful restoration is pointed out and discussed.
Reference cases of restoration projects on waters and wetlands at different latitudes and altitudes all
over the globe are described and discussed, including cases where ecological restoration was carried
out by contractors, with more and sometimes less success. All experience indicates the need of skilled
limnologists and other ecologists to guide such procedures from inception to conclusion, to reach the
final aim of restoring a sustainably functioning ecosystem.Experience and knowledge gained in resto¬
ration projects, on the processes and approaches that transform turbid green, cyanobacteria-infested
lakes into blue waters or how drained, subsiding marshes are converted into wetlands of high biodi¬
versity turn experienced ecologists into specialists in demand in research and administration.
The feeling of exultation that follows the observation that an aquatic ecosystem
—
degraded by man
—
finally has been restored to "normal" life, definitely motivates the classification of this kind of applied
ecology as an activity of the Fine Arts.
Björks
instructive book is aimed both at administrators seeking approaches and help to fix ailing aquatic
water systems and also at aquatic ecologists interested in designing taihr-made methods for restoring, moni¬
toring and documenting the results of eco-medical operations on lakes and
