Hampshire 10km distribution maps

These maps show the distribution of the main bryophyte taxa recorded in Hampshire, plotted at 10km square (hectad) resolution. The maps are based on existing records in the BBS/BRC database up to March 2016, with some more recent additions (mostly to July 2018). Taxa have mostly been grouped at the species level, but some well defined subspecies and varieties have been mapped separately. It is hoped to bring the maps fully up to date later in 2021.

The coloured shading shows the date class in which the taxon was most recently recorded in each hectad. Although the maps therefore appear to indicate that many species have declined since 1960, this is mostly due to under-recording in recent decades.


Thanks to the British Bryological Society and to Oli Pescott at the Biological Records Centre for his assistance in supplying and managing the datasets. The BBS Atlas dataset is now on the NBN Gateway (but Hamsphire records are currently only included up to about March 2014). The maps were generated from QGIS using the Tom.bio Biological Recording plugin developed for the Field Studies Council.
