This dataset includes litterfall data from the experimental plots at the Climoor field site in the Clocaenog forest, NE Wales. Litterfall (natural senesced plant material) was collected in litterfall traps (12 x 7.5cm pots standing slightly proud of the soil/litter surface, emptied monthly). Litterfall was calculated by drying the contents of the traps and weighing the samples; values were calculated for each quadrat (total weight (g) only) and for each plot (total weight (g) and weight per metre squared (g/m2)). Data spans the periods Oct 1999 to Jan 2004 and July 2008 to June 2011. Data was collected by CEH staff and PhD students trained in the use of the methods. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes measurements of annual growth of the higher plant species in the experimental plots at the Climoor field site in the Clocaenog Forest, NE Wales. Years include 1999, 2000, 2001, 2003, 2004, 2006, 2007, 2008 and 2009, and in each the measurements were taken in August (at a time of maximum veteative growth at the site). Data include maximum shoot elongation, leading shoot length, and number of flowers, leaves and branches.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset contains vegetation survey data from an upland heath site in the Clocaenog Forest. Vegetation was surveyed in the experimental plots at the Climoor site in 1998, 1999, 2000, 2002, 2003, 2007, 2008, 2009, 2010, 2011 and 2012. The vegetation at the site is a typical UK upland heathland, dominated by Calluna vulgaris, with Vaccinium myrtillus and Empetrum nigrum also being present in the vegetation understory. In each year, measurements were taken at a time period of maximum growth, which was late August/early September. This was done by pin point methodology, and data includes both pin hits as well as measurements converted into plant biomass. Individual species can be examined, as well as the different components of the higher plants (i.e. leaf, stem, flower).

This CD-ROM set contains the Volume 1 vegetation data collection. The data covers a 24 month period, 1987-1988, and all but one are mapped to a common spatial resolution and grid (1 degree x 1 degree). Temporal resolution for most datasets is monthly; however, a few are at a finer resolution (e.g., 6-hourly). This dataset contains data covering: * Background (soil/litter layer) reflectances * Fraction of Photosynthetically Active radiation absorbed by the green vegetation canopy (FPAR) * Fourier-Adjustment, Solar zenith angle corrected, Interpolated Reconstructed (FASIR) normalized difference vegetation index (NDVI) * Percentage green leaf area of total leaf area * Total Leaf Area Index (LAI) * Normalized Difference Vegetation index (NDVI) * Roughness length (Zo) * Calculated snow-free albedo * Global land cover classification from satellite data

This dataset consists of plant species presence and abundance in different sizes and types of plots from 569 1km x 1km square sites surveyed across Great Britain in 1998 and 1999 (under a project named Countryside Survey 2000). Many of the plots are repeated from surveys in 1978 and 1990 and were surveyed again in 2007. General information about the plot was recorded including plot number and type as well as species presence and (usually) cover. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes all measurements of roots from the Climoor fieldsite in the Clocaenog Forest. The data spans three periods: 2003-2004, 2008 and 2011. In 2003 and 2004, 5cm x 15cm plastic root cores were measured, and roots manually picked out the soil. In 2008, root biomass was determined by sieving and washing. In 2011, root biomass, density and length was also determined using sieving and washing. However, the methods used in each of the periods differs so significantly the data should not be directly compared, only differences between experimental plots should be considered.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes data on the degree of herbivory and infection of the fungal pathogen, Valdensia heterodoxa, on the deciduous shrub Vaccinium myrtillus in the experiment plots at the Climoor field site in the Clocaenog Forest, NE Wales. Herbivory was measured in the summer of 2000, 2005 (control and drought plots only) and 2006. Fungal infection was measured in 2000, 2005 (control and drought plots only) 2006, 2007, 2008 and 2009. Measurements were taken at the same time as annual vegetative growth and flowering assessment at a time of maximal growth (late August- early September).

The Principal Investigator in this project was Prof Ian Woodward from University of Sheffield, with 11 co-investigators at the Centre for Ecology and Hydrology (CEH), the Forestry Commission’s Forest Research, the Agriculture and the Environment Division at Rothamsted Research, and the Universities of Aberdeen, Edinburgh, Leeds, York, Oxford and Southampton. This dataset collection contains soil model output data. QUERCC addressed land surface processes over timescales from days to centuries, with particular emphasis on the carbon cycle. Some processes are already well represented and validated in Dynamic Global Vegetation Models (DGVMs), while others that are known to impact on the carbon cycle are not. Independent carbon and vegetation data sets were compared against DVGMs to assess their current state, and further key modules were developed for nutrient cycling, which exerts a major feedback on carbon exchange, and for a greater resolution of plant processes. A global map of plant functional types that exert significant impacts on the carbon cycle was also developed.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes phenology (spring emergence) data from two of the dominant higher plant species in the experimental plots at the Climoor field site in Clocaenog Forest, NE Wales. Data includes shoot length extension and growth form for Calluna vulgaris, and shoot length, phenophase and location for Vaccinium myrtillus (please refer to supporting documentation for definitions). The data were recorded in 2000, 2002 and 2004. Full details about this dataset can be found at https://doi.org/10.5285/ef0bf96f-357b-4c7e-80e4-1a33903eecdf
