About this event

The way people interact with their immediate environment varies greatly. Influenced by climate, topography, soils and vegetation, local communities may thrive or struggle. Water, the substance of life, its supply and quality are central to individual and community welfare.

Three main functional ecosystems emerged after the end of the last glacial period in Ireland: upland pine forest, lowland broadleaf forest, and helophyte (plant species whose buds overwinter under water) vegetated marshes. With the demise of the upland pine forests and the gradual removal of broadleaf forests water flow increased to streams, rivers, and lakes and influenced receiving shallow waters and stimulated peatland formation. Understanding of these processes and the role of vegetation provide the basis for understanding how the reanimation of helophyte communities may be ecologically engineered to provide sustainable water management.

The presentation will provide examples from Ireland and other countries, as to how these helophyte communities may be established and configured through the establishment of ‘Integrated Constructed Wetlands’. These examples will include their use in the sustained treatment of municipal sewage - ranging from that needed for a single house septic tank to a large conurbation exceeding 1,000 inhabitants, industrial and farmyard effluents (e.g., mining, food production, landfills and farmyard runoff), quarry drainage, and for recreational use. The diverse benefits gained from these applications will be presented. They include their capacities for the sustained prevention of water pollution and flow attenuation, habitat enhancement, environmental appreciation and recreation. Economic considerations are also presented.
