Collated indices are a relative measure of butterfly abundance across monitored sites in the UK, calculated from data collected by the UK Butterfly Monitoring Scheme (UKBMS). Collated indices are calculated annually for each individual butterfly species that has been...
Data comprises abundance measures of mites, collembola and plant biomass collected from a field experiment based at Sourhope. Experimental plots varied in nitrogen addition treatment and level of ground disturbance. The data were collected as a component of the NERC...
The data consist of observations of cover of plant species in permanent quadrats in a nitrogen deposition experiment on a peat bog. The experiment was located at Whim Moss in central Scotland, between 2002 and 2016. Recording of cover was by visual assessment in 40...
Topsoil microbe data - Bacteria. Data is representative of 0 - 15 cm soil depth and includes bacterial community structure as assessed by ordination scores, Shannon diversity index and Simpson diversity index. Over 1000 samples from 233 1km x 1km squares across Great...
This service displays a series of datasets consisting of mean estimate distribution maps of ash trees (Fraxinus excelsior) across Great Britain. It includes ash trees in areas less than half a hectare, ash trees in woody linear features and individual ash trees. The...
This record links data outputs of the NERC Historic Droughts project. The datasets comprise reconstructed hydro-meteorological time series of potential evapotranspiration (PET), river flow and ground water levels from the 1890s to 2015 for the UK. It also includes a...
The data provide critical loads of acidity, and of nutrient nitrogen for the distributions of UK habitats sensitive to acidification and/or eutrophication. Critical loads have been calculated and applied to UK natural and semi-natural habitats sensitive to acidification...
The dataset comprises counts of four planktonic diatom taxa collected from Loch Leven from 1968-2007 by staff at the Centre for Ecology & Hydrology and its predecessor bodies, as part of their long-term monitoring programme of the lake. Count units are the density of...
Data from a field-based investigation into the spatio-temporal variability of abiotic and biotic controls on peatland carbon cycling. Data was collected between February 2011 and April 2013, across an area of blanket bog peatland at Black Law Wind Farm, Lanarkshire,...
This dataset consists of autotrophic and heterotrophic soil respiration fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada. Autotrophic and heterotrophic soil respiration fluxes (CO2) were...
This dataset consists of the vector version of the Land Cover Map 2000 for Northern Ireland, containing individual parcels of land cover (the highest available resolution). Level 2 & Level 3 attributes are available. Level 2, the standard level of detail, provides 26...
Spittle Bug data from the UK Environmental Change Network (ECN) terrestrial sites. These data are collected by quadrat sampling at all of ECN's terrestrial sites using a standard protocol . They represent continuous annual records from 1993 to 2015. Spittle Bug adults...
The dataset contains measurements of temperature (°C) and light availability (Lux) in rivers in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. The stream sites monitored were chosen to...
This dataset consists of farm management data which includes crop drilling dates and herbicide application dates. The data relate to arable fields in which a range of ecological measurements were collected, including species counts in the following areas: weed seedbank,...
The resource consists of genotype data (genetic constitution of an individual organism) for three freshwater macroinvertebrate species, Amphinemura sulcicollis, Isoperla grammatica and Baetis rhodani collected at sites in upland Wales during May 2012 and May 2013. New...
The data include biomass, visible leaf injury and senescence, and ACi (net CO2 assimilation rate, A, versus calculated substomatal CO2 concentration, Ci) curves to calculate the photosynthetic parameters Jmax (maximum rate of photosynthetic electron transport) and Vcmax...
This dataset consists of invertebrate abundance data and associated ecosystem measurements (Including leaf litter depth and mass, seedlings, soil moisture and nutrients, and rainfall) measured within an area of lowland, old growth dipterocarp rainforest in the Maliau...
The dataset details surface sediment chlorophyll concentrations across six intertidal sites in the winter and summer of 2013. Chlorophyll concentrations in surface sediments (<2mm) provide a quantitative measure of the microphytobenthos (MPB) community present. Three...
This set of data comprises substrate utilisation profiles for saprotrophic fungi (using the commercially available BIOLOG plate method) and moisture content data from soils sampled from experimental plots at Sourhope, Scotland. The data were collected in order to determine...
This dataset consists of stock (area) data for Broad Habitats across Great Britain in 1990 in a 1km grid format. The data are national estimates generated by analysing the sample data from 508 1km squares surveyed for the Countryside Survey long term monitoring project,...
