As usual, I've added a previous map as it shows better where the additional records have been added, simply by flicking between the two maps. Note there's a nine-month difference between the two maps. I should add that it's a little bit of a cheat, as there are also 3766 records added from the BBS database, though it was surprising how little difference these records made to the maps overall. There are of course some very valuable records in that dataset.
Glamorgan has 614 tetrads. 257 now have totals that exceed the nominal target of 60 taxa, but clearly there's a bit of an east west split, with a large proportion of the 411 East Glamorgan tetrads still in need of recording effort. It's worth noting that 23 are shared tetrads with West Glamorgan and 66 other EG tetrads are already completed, leaving a paltry 300+ EG tetrads to look at - or to put it another way ... a paltry 300+ EG tetrads left to explore!
