Here we report on a 25-year long-term sequence of measures to return a deteriorated recreational urban lake, Alte Donau in Vienna to acceptable water quality. Metropolitan waters require focused ecosystem management plans and intensive in-lake efforts. We explored physico-chemical conditions, food web from viruses to fish and water birds, the sediments, the littoral zone and the catchment, management and urban planning, and global warming. Several restoration techniques were tested and critically evaluated. The final management plan was based on bi-stable theory. During the recovery phase, numerous surplus adjustments had to be implemented to secure sustainable achievement.
Rezensionen / Stimmen
"This book provides an instructive overview about the restoration and monitoring of a vulnerable aquatic ecosystem. Photographs and diagrams illustrate the investigated organisms and landscape and the results of measurements helping the understanding. This book can be recommended to everyone interested in either restoration techniques or shallow urban lakes." (M. Duleba, Acta Botanica Hungarica, Vol. 61 (3-4), 2019)
"The book will be of interest to many freshwater specialists as well as to those concerned with the management of lakes. It should prove of particular value to limnologists working in emerging economies where the pressures connected with urban development continue to grow." (D. Glen George, SILnews, Vol. 74, June, 2019)
