Permanent Quadrat Plant Survey Data, Buxton Climate Change Experiment, UK, 1994 and 2003

The Buxton Climate Change Impacts study was established in 1992 on a steep daleside of calcareous grassland outside Buxton, Derbyshire, UK. In five replicate blocks of 3 x 3 m plots, the vegetation has been subjected to climate treatments of winter heating (3C above ambient, Nov-April), summer drought (no rain, July-Aug), summer augmented rainfaill (20% above the long-term average, June-Sept), and two interaction treatments (heating-drought, heating-watered) in addition to replicated controls. The grassland is maintained in a short turf to simulate sheep and cattle grazing each autumn (Oct). In addition to annual point quadrat touches, the vegetation was surveyed in center-plot m2 permanent quadrats in 1994 and 2003.
