Endemic Plant Survey

A data set detailing the distribution and abundance of endemic vascular plants on St Helena. The data set comprises three parts: (1) a shapefile layer comprising polygons of the extent of each large population; (2) a point layer describing the locations of very small populations, generally where only one or two isolated plants are present, and also a selection of randomly-sampled vegetation relevees made within the polygons of Part 1; (3) a database containing information on the species present, the number of individuals and associated ecological data such as site descriptions, soil types, vegetation heights and relevees. The database in 3 will be made available separately and will probably be incorporated into the Biological Records Database. However, the data can be linked to both Shapefiles layers (1 and 2) via a unique identifier field.

Lineage	Data were compiled as part of Darwin Plus project 008 on behalf of the St Helena Nature Conservation Group. Spatial information was gathered by direct GPS plotting or via estimation where sites were inaccessible. Census data were obtained using a variety of techniques including direct counts, subsampled quadrats and transects, and photographic surveys.
