[THIS DATASET HAS BEEN WITHDRAWN].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

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes measurements of photosynthesis for the dominant higher plant species in the experimental plots at the Climoor field site in Clocaenog Forest. Plant species included are Calluna vulgaris, Vaccinium myrtillus and Empetrum nigrum. Ambient light measurements are included as well as light response curve measurements. Data was collected infrequently between 2001-2003 for Calluna and Vaccinium, and just in 2001 for Empetrum.

This dataset contains vegetation survey data from an upland heath site in the Clocaenog Forest. This was done by pin point methodology, and data includes both pin hits as well as measurements converted into plant biomass (grammes per square metre). 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. Individual species can be examined, as well as the different components of the higher plants (i.e. leaf, stem, flower). 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.

These spatial layers contain risk factors and overall risk scores, representing relative risk of Phytophthora infection (Phytophthora ramorum and P. kernoviae), for Core Native Woodland and known larch fragments across Scotland. Risk factors include climate suitability, proximity to road and river networks and suitability of habitat for key hosts of Phytophthora and were broadly concurrent with the period between 2007 and 2013. This research was funded by the Scottish Government under research contract CR/2008/55, 'Study of the epidemiology of Phytophthora ramorum and Phytophthora kernoviae in managed gardens and heathlands in Scotland' and involved collaborators from St Andrews University, Science and Advice for Scottish Agriculture (SASA), Scottish Natural Heritage (SNH), Forestry Commission, the Food and Environment Research Agency (FERA) and the Centre for Ecology & Hydrology (CEH).

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes vegetation chemistry data from the experimental plots at the Climoor field site in the Clocaenog Forest, NE Wales. It also includes data from material collected from outside, but nearby, the experimental plots. Both green and naturally senesced material was analysed between 1998 and 2010 (although not every year was included within this period). Where green material was analysed, only the current years growth was included in the sample. The dataset also includes analysis of different parts of the plants at the site, for example, Calluna vulgaris stems, Calluna vulgaris leaves. Plant species include Calluna vulgaris, Vaccinium myrtillus, Empetrum nigrum, Deschampsia flexuosa, Pleurozium schreberi. Determinants include carbon, nitrogen, phosphorus, potassium, calcium, magnesium, lignin, tannin, alpha-cellulose and carbohydrates.

These spatial layers contain the predicted occurrence and abundance of three heathland shrubs, Arctostaphylos uva-ursi, Vaccinium myrtillus and Vaccinium vitis-idaea identified as susceptible host species for Phytophthora ramorum and Phytophthora kernoviae in Scotland. The distribution models were developed from quadrat vegetation data kindly provided by Scottish Natural Heritage combined with data on climate and soil conditions as well as deer abundance and were fitted using a Bayesian Generalised Mixed Modelling approach adapted for input data on the DOMIN scale. This research was funded by the Scottish Government under research contract CR/2008/55, 'Study of the epidemiology of Phytophthora ramorum and Phytophthora kernoviae in managed gardens and heathlands in Scotland' and involved collaborators from St Andrews University, Science and Advice for Scottish Agriculture (SASA), Scottish Natural Heritage (SNH), Forestry Commission, the Food and Environment Research Agency (FERA) and the Centre for Ecology & Hydrology (CEH).

This dataset provides photosynthesis data for the plant species Calluna vulgaris, Vaccinium myrtillus and Empetrum nigrum. Photosynthesis response curves were measured for Calluna vulgaris and Vaccinium myrtillus only. Photosynthesis was measured at the climate change field site Climoor which is located in Clocaenog forest, North East Wales. Photosynthesis measurements have been carried out in 2001, 2002, 2003, 2005 and 2007; photosynthesis light response curves and Net Carbon Dioxide (CO2) assimilation rate (A), versus calculated substomatal CO2 concentration (Ci), (A/Ci), responses have been measured in 2002 and 2003. In 2005, the effects of drought on photosynthesis of all three species has been measured. In 2007, the effect climate change (warming and drought) has been measured on healthy, fungal affected and herbivory affected Vaccinium myrtillus leaves. The experimental field site consists of three untreated control plots, three plots where the plant canopy air is artificially warmed during night time hours and three plots where rainfall is excluded from the plots at least during the plants growing season (March to September). Photosynthesis measurements were carried out by trained members of CEH Bangor staff. The Climoor field experiment intends to answer questions regarding the effects of warming and drought on ecosystem processes. Plot level photosynthesis measurements are important to investigate ecosystem carbon dynamics and changes in the soil carbon under the imposed climatic treatments.

This dataset contains RGB photographs acquired from drone surveys. There are 741 harvest plots from 38 surveys at 36 sites around the world. Each site was approximately 1 ha in area. Included with the photographic images are the coordinates of ground control markers, biomass, taxonomic and location data for harvest plots and ancillary metadata. The observations can be used to obtain allometric size-biomass models. This work was supported by the Natural Environment Research Council award number NE/R00062X/1 as part of the project 'Do dryland ecosystems control variability and recent trends in the land CO2 sink?'

The dataset consists of long-term vegetation monitoring data from the Hard Hill burning plots sited in the Moor House - Upper Teesdale National Nature Reserve, Cumbria. An experiment to investigate the effects of rotational burning and grazing was initiated in 1954, consisting of a replicated block layout. Initial vegetation recording was carried out in 1961 and 1965 using a quadrat method and DOMIN scale. In 1972 onwards, vegetation was recorded using a pin frame. Data were recorded by staff from the Centre for Ecology & Hydrology and its predecessors. Full details about this dataset can be found at https://doi.org/10.5285/0b931b16-796e-4ce4-8c64-d112f09293f7
