“The Ecological Database of the British Isles has been constructed from a wide variety of sources by Dr Helen Peat and Professor Alastair Fitter at the University of York, with financial support from the British Ecological Society and the Natural Environment Research Council. It consists of data on over 2200 species of higher plants that occur in the British Isles, together with the bibliography of sources. This version has been produced by Dr Henry Ford.
The data comprises information on taxonomy (family, genus, specific name, authority, and vernacular name, together with a synonomy), a suite of over 130 ecological and morphological characteristics, vice-county distribution in Britain, European distribution by country, mycorrhizal associations, phytophagous insects and fungal diseases. The data are obtained from the literature and therefore coverage varies greatly between species. Some data sets are incomplete at this stage.”
