River Habitat Survey (RHS) data 2007 [Countryside Survey]

River Habitat Survey (RHS) data from rivers and streams surveyed in 2007 as part of the Countryside Survey project. River Habitat Survey (RHS) is an assessment of the physical structure of freshwater streams and rivers based on a standard 500m length sample unit. It does not require specialist geomorphological or botanical expertise but consistent recognition of features included on the form is essential. To ensure consistency of recording all surveyors must be accredited, and recording follows standard protocols. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology. 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. Headwater stream surveys have been carried out in 1990, 1998 and 2007 with repeated visits to the majority of sites. 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 headwater stream data, soil data, habitat areas, vegetation species data and linear habitat data are also gathered by Countryside Survey.
