There have been quite a few developments in how BWARS deals with species - primarily moving to a species concept basis. Simply put, this relates the interpretation of a name to a publication, which in turn relates to the type specimen. A more complete illustration can be found in the downloads on this page.
All data received, verified and validated by BWARS up to 2020 has been mapped.
We would be very grateful for any comments regarding these maps. There are always errors which creep in, your vigilance in pointing these out is greatly valued.
Some modern papers which relate to some of the changes in species concepts are also available as downloads here.
All the species maps can now be found on the species concept pages
species name: iso. source : year of publication
iso: in the sense of
source: author of the species description and key
year: year of publication of species description and key (NB. This is NOT the date of the map. Most maps include records up to 2020)
map created on: date map was created
DATE CLASSES FOR MAPS:
Darkest green squares are 2015 to present;
Dark green squares are 2005 to 2014;
Light green squares are 1995 to 2004;
Palest green squares are for records earlier than 1995
