Should add there are known cases where specific trees have been EXCLUDED
from mapping.

The one which comes to mind is the national database of native Black
Poplars<http://sppaccounts.bsbi.org.uk/content/populus-nigra-1>(*Populus
nigra betulifolia*) maintained by the BSBI recorder for the taxon, Fiona
Cooper. In her book on the tree (available at remaindered book
specialist Postscript
Books<http://www.psbooks.co.uk/BookDetailsBySubj.asp?ver=Fts&prm=Natural+History&sel=False&selG=False&subG=True&Code=40345&pg=Natural+History&ur=Science_Nature_Natural_History_Fts.asp?pgn%3D17&pgSz=15%23Nav40345>at
the moment) she kept many the details of many records secret.
Apparently
Black Poplar enthusiasts were a bit casual about walking on private land in
their quest with the result that landowners were destroying the trees.
