Buxton Climate Change Impacts Study

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). Vegetation response data are available in three forms:

1. The vegetation has been surveyed annually since 1994 with nondestructive point quadrat touches (with gaps in 2005, 2007, and 2008) in early summer that correlate with total plot biomass (see Grime et al. 2008 for details). Point quadrat data (1994-2009) are available here: http://knb.ecoinformatics.org/knb/metacat/fridley.3.2/knb

2. In 1994 a 1 m2 permanent quadrat was established in each plot and vacular plant cover was surveyed in 1994 and 2003, along with soil depth. The permanent quadrat cover data are available here: http://knb.ecoinformatics.org/knb/metacat/fridley.7.1/knb

3. Permanent microsite quadrats were established within each 3x3 m plot in 2008 at the 100 cm2 scale (8 per plot; see Fridley et al. 2011 for details). Species cover and environmental parameters have been monitored in microsites annually (2009-2011 controls only). Microsite vegetation data are available here:http://knb.ecoinformatics.org/knb/metacat/fridley.9.1/knb
Environmental data including soil depth and pH for each microsite are available here:http://knb.ecoinformatics.org/knb/metacat/fridley.11.1/knb

Great Smoky Mountains National Park Temperature Network data

Summary temperature maps for 2005-06 for Great Smoky Mountains National Park are available as Google Earth files here; see Fridley 2009 for details. Daily ground-level temperature data for particular park regions (2005-2006) are available through GSMNP or via email to Jason Fridley (data up to 2009).

Alien Plants of the Eastern U.S. database

Native floristic and habitat characteristics of the alien (naturalized) and invasive floras of the Eastern U.S. are available as a supplementary spreadsheet at PLoS ONE, found here:
