The objectives of the Database and Atlas of Aquatic Vascular Plants project are to update or, where necessary, create computer files of records (with locality data) of 209 submerged, floating and emergent aquatic vascular plant taxa, and to summarise the known distribution of these taxa as maps. The project is planned in two stages. In Phase I (1989-1991) data were acquired on the 124 submerged and floating species (Preston, Croft and Forrest 1991). Work was also begun on capturing data from site-based datasets, i.e. those datasets which consist of lists of species at particular sites rather than lists of sites for particular species. This interim report covers the first year of Phase II (19911992), in which work on 36 site-based datasets has been completed. In the final year of the project (1992-1993). at least three further site-based datasets are expected in machine-readable form, data will be acquired on 85 emergent species and an Atlas of Aquatic Plants prepared for publication.
