Abundance of plant taxa on Norwood Farm, Somerset during 2007 and 2008

Estimates of plant abundance (for leaf area, floral units and seed abundance, mass and energy) obtained from field-based sampling as part of a study of ecological interactions (food webs and plant-pollinator networks) on a single farm (Norwood Farm, Somerset, UK: 51.3128N 2.3206W) during 2007 and 2008. During the study, Norwood Farm was managed as an organic farm at relatively low intensity. The work was was supported by the Biotechnology and Biological Sciences Research Council [grant number BBD0156341].,Field surveys were conducted according to established protocols. Records made in the field for plant cover, height and counts of floral units, or samples containing seeds were collected for laboratory sorting and analysis. Data were entered into a purpose-designed database, via bespoke forms to support accuracy of data entry. Manipulations on the raw data (e.g. scaling up from sample size to total habitat area) were conducted in the database and data were checked for consistency of species names and data entry errors throughout the analysis undertaken as a contribution for peer-reviewed papers.,
