BWARS Maps and Species Concepts

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
