The Millennium Seed Bank project aims to collect and conserve seeds from up to 25 thousand species over ten years. In so doing, Kew's Seed Conservation Department (SCD) has a unique opportunity to capture and store large amounts of taxon-based information on a range of seed biological characteristics, both from the collections and published sources. While the primary intention is to analyse these data for predictive patterns that support seed conservation operations, it is likely that a wide variety of users outside the project will find the data valuable for many purposes. To aid both in-house analysis and dissemination to outside users, SCD is developing a Seed Information Database (SID) and populating it with data. SID is one of Kew's strategic databases and now forms part of the institute's electronic Plant Information Centre (ePIC) project, in which species name is a common field linking a number of other taxon databases.
