  • This dataset includes ecological information recorded from within 18 birch woodlands surveyed in the Spey Valley, Scotland between 1971 and 1974. Data collected includes plant species composition in the canopy and ground flora, soil pH, habitat management and a wide range of other descriptors at a site level and in more detail from 16 - 40 200m2 sample plots located at random within the 18 woods. The survey was undertaken by the Nature Conservancy/Institute of Terrestrial Ecology. Full details about this dataset can be found at

  • Terrestrial habitat, vegetation and soil data from a survey of Shetland, carried out in the summer of 1974 by the Institute of Terrestrial Ecology. Nearly 1000 x 200m2 plots were surveyed from across the islands, selected on the basis of a stratified sampling strategy. Details about plant species, soils, habitat types and major biota present were collected using standardized survey methods. This survey was part of a larger project to assess the status and value of Shetland's plant and animal species and communities. Full details about this dataset can be found at

  • The Land Classification of Shetland is a classification of the Shetland Isles into a set of 16 environmental strata, termed land classes, to be used as a basis for ecological survey, originally developed by the Institute of Terrestrial Ecology (ITE) in 1974. The strata were created from the multivariate analysis of 150 environmental variables, including topographic data, geographical features and geology data. The Land Classification can be used to stratify a wide range of ecological and biogeographical surveys to improve the efficiency of collection, analysis and presentation of information derived from a sample.

  • This is a web map service for the Land Classification of the Shetland Isles. The classification was originally developed by the Institute of Terrestrial Ecology (ITE) in 1974 as a framework for ecological sampling and is a stratification of the land into a set of sixteen environmental strata at a 1km resolution. Each strata is an area sharing similar environmental characteristics (such as altitude, geology, distance from sea). The web map service contains two layers: 1) EnvironmentalStrata - all sixteen land classes; 2) OverviewOfStrata - land classes arranged into four related groups. The strata may briefly be described thus: Classes 1-4 - Coastal strata with few rivers running into the sea, gentle terrain; Classes 5-8 - Coastal strata with more sea and steeper slopes; Classes 9-12 - High altitude inland group, with few small water bodies; Classes 13-16 - Lower altitude zones with much peat and freshwater lochans. The four strata within each of these groups contain subtly different variations.
