Distribution maps of species records held at BIS

At the recent BIS Recorders Forum we displayed a range of distribution maps, produced from ArcView, which show the number of records held by BIS on a 1km square basis in November 2008. These were also broken down into some of the major taxon groups for Vascular plants,lower plants, birds. They can now be viewed in the attatched pdf files.

These maps can be used to target further recorder effort and also to highlight data sets that are not yet available to BIS. The analysis can be further extended to look at individual species or genera, and by date classes.
