Distribution Maps
Posted: Tue Jun 17, 2008 1:20 pm
What are peoples' views on the accuracy of distribution maps in eg Collin's new guide?
I have just received my copy, and very good it is too, but I was struck by the differences that always appear between books for the distribution maps. A good example is for a species I see quite often in France (S. White Admiral) where I know full well that it is quite common in areas outside those shown.
Is there a "definitive" set of distribution maps I can refer too?
