This web map service displays existing and potential areas of habitats associated with calcareous, coastal, upland and lowland heath landscapes. The dataset was initially created to provide a sampling framework for a field survey carried out in 1992 and 1993 by the Institute of Terrestrial Ecology (later part of the Centre for Ecology & Hydrology). It was derived from a range of geology, soils, altitude and land cover data.

This dataset includes data collected from the hillslope with tree shelterbelt study site located within the Pontbren study catchment in mid-Wales, UK. The hillslope is an area of improved grassland that has had a strip of trees contour planted across it that was instrumented between 2005-2009 as part of the Pontbren Catchment Study Land Use and Management Multi-Scale Experimental Programme. Within the Pontbren hillslope dataset folder are overland flow runoff collected from overland flow traps within the tree shelterbelt (Hillslope tree shelterbelt overland flow sub-folder), overland and drain flow occurring above the hillslope (Hillslope runoff weir box sub-folder), and soil water pressure data measured using tensiometers installed above, within and below the tree shelterbelt (Hillslope tensiometers sub-folder). Details of the monitoring system locations are provided in the Pontbren Catchment Study Data Catalogue. Overland flow and drain flow from the hillslope immediately above the tree shelterbelt was monitored using weir box systems between 2006-2009. Pressure transducers installed in the weir boxes were sampled every minute and averaged and logged every five minutes to provide estimates of flow (ls-1). Three transects of tensiometers installed above, within and below the tree shelterbelt provide soil water tension data (cm H2O) for the period 2005-2009. Overland flow data are also provided from 2 overland flow traps installed within the tree shelterbelt for the period 2005-2009. Traps were installed to collect data from two 5 m x 5 m isolated plots. Initially plots were set up so that the cumulative overland flow volume (mm) occurring between site visits could be measured. This setup was then replaced by tipping bucket systems connected to data loggers (logged every 10 minutes) to provide continuous overland flow (ls-1) data from these plots. Data are provided in the form of .txt files and generally split into 6 month blocks. Note that within the Hillslope tree shelterbelt overland flow subdirectory files with T1 and T2 in the name refer to overland flow traps 1 and 2 respectively. Associated with each data point in the .txt file is a quality assurance code, QA code, in the adjacent column. Details of the dataset and the quality assurance coding system are provided in the supporting documentation. Other measurements taken at the hillslope study site include soil volumetric moisture content and groundwater height. Datasets of these other parameters are provided by the EIDC.

This web map service shows bee nectar plant richness across Great Britain . The source data uses counts of bee nectar plants in Countryside Survey area vegetation plots in 2007 and extrapolates to 1km squares across GB using a generalised additive mixed model. Co-variables used in the model are Broad Habitat (the dominant broad habitat of the 1km square), air temperature, nitrogen deposition, precipitation and altitude. The map has the following layers: plantCount = a modelled estimate of the count of all bee nectar plants within a 1km by 1km square, SEM = a measure of the variance of the plantCount attribute Understanding the distribution of bee nectar plants does provide valuable information on the potential distribution of pollinators and hence pollination.

This web map shows positive plant habitat condition indicators across Great Britain (GB). This data provides a metric of plant diversity weighted by the species that you would expect and desire to have in a particular habitat type so indicates habitat condition. In each Countryside Survey 2007 area vegetation plot the number of positive plant habitat indicators (taken from a list created from Common Standards Monitoring Guidance and consultation with the Botanical society of the British Isles (BSBI)) for the habitat type in which the plot is located are counted. This count is then divided by the possible indicators for that habitat type (and multiplied by 100) to get a percentage value. This is extrapolated to 1km squares across GB using a generalised additive mixed model. Co-variables used in the model are Broad Habitat (the dominant broad habitat of the 1km square), air temperature, nitrogen deposition, sulphur deposition, precipitation and whether the plot is located in a Site of Special Scientific Interest (SSSI) (presence or absence data).

This web map service presents modelled estimates of soil pH, carbon concentration (g kg-1), nitrogen concentration (% dry weight soil) and invertebrate density (individuals m-2) at 1km2 resolution across Great Britain. A Generalized Additive Model approach was used with Countryside Survey soil data from 2007 and including climate, atmospheric deposition, habitat, soil and spatial predictors. The models are based on data from Countryside Survey sample locations across Great Britain and are representative of 0-8cm soil depth for invertebrates and 0-15 cm soil depth for other variables. The Countryside Survey looks at a range of physical, chemical and biological properties of the topsoil from a representative sample of habitats across the UK. Loss-on-ignition (LOI) was determined by combustion of 10g dry soil at 375 degrees Celsius for 16 hours; carbon concentration was estimated by multiplying LOI by a factor of 0.55. Soil N concentration was determined using a total elemental analyser. Soil pH was measured using 10g of field moist soil with 25ml de-ionised water giving a ratio of soil to water of 1:2.5 by weight. Soil invertebrates were extracted from cores using a dry Tullgren extraction method and enumerated by microscope

The WATCH Forcing data is a twentieth century meteorological forcing dataset for land surface and hydrological models. It consists of three/six-hourly states of the weather for global half-degree land grid points. It was generated as part of the EU FP 6 project "WATCH" (WATer and global CHange") which ran from 2007-2011. The data was generated in 2 tranches with slightly different methodology: 1901-1957 and 1958-2001, but generally the dataset can be considered as continuous. More details regarding the generation process can be found in the associated WATCH technical report and paper in J. Hydrometeorology. To understand how the data grid is formed it is necessary to read the attached WFD-land-long-lat-z files either in NetCDF or DAT formats. The data covers land points only and excludes the Antarctica. Snowf or snowfall is the snowfall rate based on the GPCC bias corrected, undercatch corrected measured in kg/m2/s at 3 hourly resolution averaged over the next 3 hours and at 0.5 x 0.5 degrees spatial resolution. Please note that there is also a WFD Snowf CRU bias corrected dataset, but as the GPCC dataset is the preferred dataset only this snowfall dataset is available from the EIDC. These snowfall datasets contain snowfall data only and need to be combined with the respective WFD rainfall datasets to obtain precipitation data.

This dataset is from an array of tensiometers measuring soil water tension installed at the Llyn Hir monitoring site within the Pontbren study site in mid Wales, UK. Three tensiometers were installed at 10 cm, 30 cm, and 50 cm depth and sampled every 10 minutes between September 2008 to December 2009 as part of the Pontbren Catchment Study Land Use and Management Multi-Scale Experimental Programme. The Llyn Hir site is an area of unimproved grassland adjacent to the Llyn Hir rain gauge and Llyn Hir outflow stream gauging site (Site 8). Soil water tension data (cm H2O) are provided in the form of .txt files and generally split into 6 month blocks. Associated with each data point in the .txt file is a quality assurance code, QA code, in the adjacent column. Details of the dataset and the quality assurance coding system are provided in the supporting documentation. Datasets from the rain gauges and stream monitoring system at the Llyn Hir site are also provided by the EIDC.

LCM2007 is a parcel-based thematic classification of satellite image data covering the entire United Kingdom. The map updates and upgrades the Land Cover Map of Great Britain (LCMGB) 1990 and LCM2000. Like the earlier 1990 and 2000 products, LCM2007 is derived from a computer classification of satellite scenes obtained mainly from Landsat, IRS and SPOT sensors. It also covers Northern Ireland and incorporates information derived from other ancillary datasets. LCM2007 was classified using a nomenclature corresponding to Joint Nature Conservation Committee (JNCC) Broad Habitats, which encompasses the entire range of UK habitats. In addition, it records further detail where possible, incorporating land cover classes sought by other users. LCM2007 is produced in both vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions. Product consists of the dominant Target Class per 1km square, raster dataset (Northern Ireland only).

This web map service shows the suitability of climate conditions for infection of Phytophthora ramorum and Phytophthora kernoviae across the UK. Suitability is mapped for individual years 2007 to 2011; the average and standard deviations for the whole period are also provided. The model is based on laboratory data of environmental responses of these pathogens and hourly temperature and relative humidity regimes in the period, and describes how many times infection could have been completed within running 48 hour periods through the year. 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).
