Abstract

The AA. compare 2 commonly used methods in small Danish streams to improve the physical condition : re-meandering and passive restoration through cease of maintenance. The investigation included measurement of the physical conditions in 29 stream reaches covering 4 different groups : 1) re-meandered streams, 2) LDC streams (the least disturbed streams available), 3) passively restored streams (>10 years stop of maintenance) and 4) channelized and non-restored streams. The in-stream habitats were compared through analysis of the measured physical parameters and by applying a habitat model. The AA. found that re-meandering is a more effective way of re-creating near-natural physical conditions in small streams compared to passive restoration. However, based on habitat suitability modelling, the change to the physical condition did not translate into improved habitat suitability for young of the year brown trout highlighting the value of using several methods when evaluating restoration success
