Recording all plants growing wild in Somerset, not just the rarities!

Recording in Somerset

Somerset comprises two vice-counties: South Somerset (VC5) and North Somerset (VC6).map showing county and vice county boundaries

Members of Somerset Rare Plants Group record at a scale of monad (1km square) level, or finer. Displays of records/species per monad will be available soon.

Six, eight or ten figure grid references are routinely recorded for rarer species.


VC5 consists of 1838 complete monads and 421 partial ones

VC6 consists of 2085 complete monads and 314 partial ones


The mapping programme MapMate is used by the Somerset VCRs to store, analyse and share data, all records being passed on to the Botanical Society of the British Isles.  MapMate has only been routinely used for Somerset plant records since the late 1990s.  Many historical records have yet to be added; however the records collected for the Atlas Flora of Somerset (by P.R. Green, I.P. Green and G.A. Crouch, 1997) have been added to MapMate as “skeleton” tetrad spots (with no precise date or recorder details).


Using MapMate, the density of both species and records can be mapped at tetrad level.

Since the Atlas Flora of Somerset covered only modern administrative Somerset, coverage of the north part of VC6 appears sparse on maps of all records.  Maps of species and records per tetrad since 2000 (which do not include the Atlas Flora of Somerset records) have also been generated.  These will be helpful in directing recording effort for the BSBI’s planned Atlas 2020.

In Somerset, all recording is at monad scale or better, so to help target recording for Atlas 2020 species density per monad has also been mapped using MapMate.
