Methods of enhancing botanical diversity in lowland swards undergoing extensification - BD0309

Although there has been much research on the impoverishment of botanical composition in lowland swards following intensification, few studies have focussed upon the rate and magnitude of successional changes associated with extensification of such swards, particularly on acidic soils which experience high rainfall. This study will examine methods of enhancing botanical diversity in a lowland sward undergoing extensification, with emphasis on treatments designed to speed up successional change and enhance botanical diversity following reduction or elimination of fertiliser inputs. Effects of fertiliser withdrawal on herbage yield will also be assessed, while wildflower establishment will be compared across treatments used. Results will be used to develop cost effective options for enhancing biological diversity in grasslands undergoing extensification.
