Countryside Survey 1990 estimates of Broad Habitat areas in Great Britain

This dataset consists of stock (area) data for 16 Broad Habitats across Great Britain in 1990. The data are national estimates generated by analysing the sample data from 508 1km squares and scaling up to a national level. The data are summarized as habitat area per Land Class (areas of similar environmental characteristics). The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB and using the 'ITE Land Classification' as a method of stratification. The data were collected as part of Countryside Survey, a unique study or 'audit' of the natural resources of the UK's countryside. The Survey has been carried out at regular intervals since 1978. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 with repeated visits to the majority of squares. In addition to habitat areas, vegetation species, soil data, linear feature data and freshwater habitats are also gathered by Countryside Survey.
