Environmental River Enhancement Programme (EREP)
Topic of the practice
The project wished to ‘enhance’ river corridors along arterially drained channels, managed by the Office of Public Works (OPW), through either a Capital Works programme or through use of Enhanced Maintenance strategies. In both cases, it was envisaged that ‘enhancement’ or increased diversity of the physical and flow regimes would facilitate increases in biodiversity.
Good Practice Information
PROBLEM: The creation of Arterial Drainage Schemes brought many negative impacts on the river corridor habitat
OBJECTIVES: Enhance river corridors along arterially drained channels. Increases in biodiversity.
• Capital enhancement- importation of rock and spawning gravels to help restore or enhance OPW drained channels
• Enhanced maintenance- available on-site materials are used
The EREP, which commenced in 2008, is an OPW funded project, coordinated and managed jointly with Inland Fisheries Ireland (IFI). The EREP has been set up to strategically align with the OPW's obligations under EU Water Framework Directive and the National Biodiversity Plan, and is a proactive approach to improve the ecology of drained rivers in Ireland.
Evidence of success
RESULTS: It is envisaged that the enhancement or increased diversity of the physical and flow regimes would facilitate increases in biodiversity.
TRANSFERABILITY: It could be transferred as a significant step in addressing the issue of fisheries protection, the enhancement of river corridor aquatic environments and an increase in the level of biodiversity.
