The blue notebooks are more location-specific than the red ones. They are divided into separate sub-groups according to location, with an abbreviated key on the spine. Within each sub-group (for example the Hayley Wood books) pagination is continuous from notebook to notebook. They tend to contain more raw data than the red notebooks, for example tally charts showing frequency of particular plant species in particular areas of woodland, with photocopied maps of woodland areas often pasted in. Although sequence is roughly chronological, information is entered in a more content-led fashion than in the red notebooks.
