Characterizing fish responses to a river restoration over 21 years based on species traits
Understanding restoration effectiveness is often impaired by a lack of quality, long term monitoring data and, to date, few studies have used species trait information to gain insight into the processes that drive reaction of fish communities to restoration. Authors examined fish community reponses using a highly resolved dataset with 21 consecutive years of data (four years pre- and 17 years post restoration) at multiple restored and unrestored sampling reaches from a river restoration project at the Lippe River, Germany.
The restoration led to a doubling of both species richness and abundance. Abundance exhibited an overshooting reponse immediately following restoration and both richness and abundance stabilized approximately seven years after restoration. However interannual variability remaining high, illustrating the challenge to reliable assess restoration outcomes based on data from individual sampling, especially in the first years follwong restoration.
