A CHECKLIST OF THE FLORA OF STAFFORDSHIRE
The previous checklist for the county was prepared by Ian Hopkins:
Hopkins, I.J. (1985) Staffordshire Flowering Plants and Ferns . Stoke-on-Trent City Museumand Art Gallery.
He used information from E.S. Edees' Flora of Staffordshire (1972 David & Charles) as a
basis for frequency assessment with some changes where additional/more recent data suggestedit was necessary. 800 tetrads were involved.
Work on a new Flora commenced in 1998, with contributions from many botanists.
Species accounts and distribution maps were completed in December 2010. The number of tetrads in which each taxon occurred within the period post-1994 wasascertained and its frequency assessed.
The earlier checklist employed six frequency categories and this method is adopted
here. However, the more recent Flora covers a larger geographical area than the earlierone. It includes all areas that have, at any stage, been included in administrative Staffordshire as well as the botanical vice-county (VC 39): all or part of 885 tetrads. Consequently, the upper limit of each category boundary has been raised by 10%:
Very Common 649 - 885 tetradsCommon 275 - 648 tetradsFrequent 110 - 274 tetradsUncommon 39 - 109 tetradsRare 9 - 38 tetradsVery Rare 1 - 8 tetrads
Some sub-specific taxa have been under-recorded by some botanists and the same is
certainly true within critical groups. Where the compiler is convinced in his own mind that the true frequency of occurrence would almost certainly move the frequency into the categoryabove that corresponding to the actually recorded figure, a * is added. Thus:"Dryopteris affinis ssp. affinis….Rare*" indicates that many of the records for Scaly MaleFern were not determined to subspecific level and that, if they had, the frequencylevel of this ssp. would almost certainly be raised to "Uncommon".
Although D.P. Earl has kindly provided many Rubus records, these were only from the
north of the county. Those species which are extremely likely to be frequent enough furthersouth to raise the frequency category are marked "‡"
The frequency of Salix x sepulcralis is given as "Rare†". It is almost certainly
"Uncommon", having often been incorrectly recorded as "S. babylonica ", which has not recently been confirmed for the county.
Very recent work on Hieracium acuminatum indicates that it was previously largely
misidentified. It may well be very rare, or even absent from Staffordshire, rather thanfrequent. It is designated "Frequent¥"
The list follows the taxonomic order of the Second Edition of New Flora Of The British Isles . Clive Stace (1991). Cambridge
The new Staffordshire Flora contains full acknowledgements of those organisations
(including Staffordshire Ecological Record, Staffordshire Wildlife Trust and EcoRecord) andthe many individual botanists on whose records this list is based.
