Environmental River Enhancement Programme 2008 – 2012

Final Report

EREP 2012 Annual Report
As part of the 2012 programme approximately 105km of channel were identified for works through either enhanced maintenance or capital works programmes and 80km were completed. All channels were walked and a written enhancement report provided to OPW. Monitoring of the physical habitat and biological elements pre and post works at a number of these channels, across all OPW regions, is on-going with a number of experimental works also being undertaken. These scientific studies aim to assess the effectiveness of such works on the river corridor biodiversity and hydromorphology. While data is collected annually on fish communities, riparian and instream vegetation, aquatic macroinvertebrates, birds, crayfish and lamprey, it is often more appropriate to have several years data available before a full account of impacts is presented.
