Conservation Management of Hay Meadows in the Elan Valley
The Elan Valley, in mid-Powys, includes some of the most important and richest examples of unimproved mesotrophic grasslands in Wales. The majority of these are highly species-rich upland-fringe meadows that are now mostly designated as Sites of Special Scientific Interest (SSSIs) due to their national significance. In order to help safeguard the future of these important sites the Elan Valley Meadow Project was initially set up in 2004 to address both the management of the existing species-rich grasslands and their potential expansion. The project was managed and implemented by a partnership between the Elan Valley Trust, Natural Resources Wales (Natural Resources Wales) (formerly Countryside Council for Wales; CCW) and independent ecological consultants. The primary objective of the project was to provide site-specific and ecologically sustainable management advice to help conserve these important and regionally distinct upland-fringe meadows. Specifically there was a need to determine what levels of nutrient inputs are required to enable reinstatement of traditional hay making practices while still conserving existing high levels of floristic diversity. To this end a long-term replicated field trial was undertaken to determine how a representative group of the Elan Valley meadows respond to different inputs of farmyard manure (FYM) and/or lime in terms of soil chemistry, herbage productivity and changes in species diversity.

The experimental plots for investigating the application of varying levels of farmyard manure and lime were initially established during autumn 2004. The experiment consisted of a randomised block design of 6 nutrient application treatments in five replicate blocks (sites). The five sites were established in separate meadow enclosures at three different holdings: two at Hirnant, two at Penglaneinon and one at Rhos yr Hafod. Four of the sites were located within homogeneous stands of species-rich MG5a grassland, while one of the Hirnant sites was sited within an area of less species-rich MG6 grassland undergoing meadow restoration management.
