The BLS Spreadsheet (v7.11 2023) can be used for all habitats, including churchyards. It uses the taxon dictionary as it was in October 2023 so some of the names displayed back in the green columns may be unfamiliar, but you don't need to know these and can still enter the old names or the BLS numbers to the white columns as before. The spreadsheet will do the rest, so please do not type anything in to the green columns.
This spreadsheet is designed to be used in modern versions of Excel and so is in .xlsx format, but it should also work in OpenOffice or under windows emulation. If you have an older or non-windows computer that won't run it please ask email@example.com for a cut-down version.
The Guidelines document includes help on using the spreadsheet and our substrate and scale habitat codes, and the handout from the training session run at Cober Hill in March 2019 may also be useful.
