This aggregation consists of datasets collected as part of the Isle of May long-term study (IMLOTS) on the ecology of six seabird species breeding on the Isle of May National Nature Reserve, off the East coast of Scotland: black-legged kittiwake (Rissa tridactyla),...

This dataset contains data from the National Plant Monitoring Scheme in 2015. These consist of plant species occurrences, with abundance values, in plots. Plots are nested with 1 km squares, and are georeferenced according to the British/Irish/Channel Islands grid systems,...

This series of datasets consists 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 data are derived from...

This dataset consists of weekly mean sizes of Perch (Perca fluviatilis) from trapping at Green Tuft, Windermere, Cumbria, sampled between 1946 and 2012. Perch have been monitored in the north and south basins of Windermere by trapping with variations in sampling sites...

This datset contains operational taxonomic units for epilithon eukaryotes (water samples): Approximate location of sampling sites was determined from maps to provide good spatial coverage of the Wold River through to the Tamar River. Exact sites were determined in the...

This dataset provides the details of all sites which have been monitored as part of the UK Butterfly Monitoring Scheme (UKBMS). Data includes the location within the UK, the length and width of the line transect on each site, and how long the transect has been monitored....

This dataset consists of growth (length) data on Pike (Esox lucius) from net sampling in Windermere. Data collection began in 1944. The data were initially collected by the Freshwater Biological Association (FBA) but have been collected by CEH and its predecessor Institute...

This is a series of datasets available from the UK Butterfly Monitoring Scheme (UKBMS). The UKBMS comprises a suite of surveys carried out each year across the UK that generate data on butterfly abundance. The UKBMS started in 1976 (few sites from 1973) with thirty-six...

The data consists of plant physiological measurements from 15 sites located in the Conwy catchment (North Wales) and from 2 sites in North West England. Plant photosynthetic parameters for the maximum rate of carboxylation (Vcmax), the maximum rate of electron transport...

This dataset consists of vegetation abundance data from four experiments investigating the management of arable field options for rare plants. These experiments consisted of a margin management experiment, a herbicide screening experiment, a cereal headland experiment...

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...

Site indices, as a relative measure of the actual population size, for UK butterfly species calculated from data from the UK Butterfly Monitoring Scheme (UKBMS). Site indices are a relative rather than an absolute measure of the size of a population, and have been shown...

Site indices, as a relative measure of the actual population size, for UK butterfly species calculated from data from the UK Butterfly Monitoring Scheme (UKBMS). Site indices are a relative rather than an absolute measure of the size of a population, and have been shown...

This dataset contains operational taxonomic units for soil eukaryotes from the Wolf and Tamar catchments . A range of soils were targeted from the Tamar region comprising a range of land uses. Approximate location of sampling sites was determined from maps to provide...

This dataset consists of information regarding the abundance of fish species from Windermere, and includes long-term data on Arctic Charr (Salvelinus alpinus), Pike (Esox lucius), Perch (Perca fluviatilis) and some recent data on Roach (Rutilus rutilus) from net and...

This dataset provides linear trends, over varying time periods, for the UK Butterfly Monitoring Scheme (UKBMS) Collated Indices of individual butterfly species across the UK. The main statistical values derived from a linear regression (slope, standard error, P-value)...

Data on genetic variation in Acacia senegal across its natural range, based on two chloroplast marker types - RFLP (restriction fragment length polymorphism) and microsatellites.

The data consist of species level descriptions of macroinvertebrate communities from two abstracted streams in the Lowther catchment, UK, upstream and downstream of abstraction points. Supporting habitat and geographical data are included.

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...

The dataset contains information on the species identity and frequency of all insect-flower interactions recorded in 10 birch (Betula spp.) woodland fragments surveyed in 2009 (May-August). The data were collected in two transects (50 × 2m; 15m apart and at least 50m...
