Countryside Survey 1978 mapped estimates of Broad Habitat areas in Great Britain

This dataset consists of stock data for Broad Habitats across Great Britain in 1978. The data are national estimates generated by analysing the sample data from 256 1km squares surveyed for the Countryside Survey and scaling up to a national level. The data are presented as percent habitat per 1km square. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 with repeated visits to the majority of squares. 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. In addition to habitat areas, species plot, soil plot, linear habitat, freshwater habitat and satellite map data are also produced by Countryside Survey.

本数据集汇集了1978年英国广域栖息地的股票数据。数据为国家估算值，通过对乡村调查中256个1平方公里方格的样本数据进行分析并扩展至全国范围而生成。数据以每平方公里栖息地百分比的形式呈现。乡村调查是对英国乡村自然资源的独特研究或‘审计’。样本点基于GB的15x15公里网格进行分层随机选取。调查于1978年、1984年、1990年、1998年和2007年进行，并对大多数方格进行了重复访问。乡村调查采用严格的科学方法进行采样和调查，使我们能够将新结果与先前调查的结果进行比较。通过这种方式，我们可以检测到英国乡村随着时间的推移所发生的逐渐而微妙的变化。此外，乡村调查还产生了物种样地、土壤样地、线性栖息地、淡水栖息地和卫星地图数据。关于本数据集的详细信息，请参阅https://doi.org/10.5285/df180b2e-36ea-410e-8487-5a09942afa9e。
