Abstract
The Hay Time project was set up in 2006 by the Yorkshire Dales Millennium Trust (YDMT) and the Yorkshire Dales National Park Authority to make a significant contribution towards the UK Biodiversity Action Plan (BAP) targets for expansion/restoration of upland hay meadows (UHM). Over the last seventy years, there has been a dramatic decline in the extent and quality of UHM. This paper reviews methods for the restoration and management of UHMs.
