River Blackwater historic river corridor surveys

Former National Rivers Authority paper records for river corridor surveys of the River Blackwater in Essex, held by the Environment Agency and digitised by Essex Wildlife Trust on their behalf using funding from the NBN data capture initiative. Data consists mainly of botanical records from old recording cards, although there are some records for other taxa.

Paper copies of these surveys are held by Essex Biodiversity Project, scanned copies of the site descriptions and sketch maps accompanying this data are held digitally by Essex Wildlife Trust Biological Records Centre.
