Changes in groundwater levels, temperature and quality in the UK over the 20th century: an assessment of evidence of impacts from climate change

[摘要] In 1971, 103 broadleaved woodlands were surveyed across Britain. Ecological information was recorded at the site level and in more detail from 16 200m2 sample plots located at random within each site. Data was collected on plant species composition in the canopy and ground flora, soil pH and Soil Organic Matter, habitat management and a wide range of other plot and site-level descriptors. All sites and, where possible, sample plots were revisited and recorded again over the growing seasons of 2000, 2002 and 2003 (referred to as ��2001 survey��), using exactly the same field methods. This document describes how the data are stored.
