Glad you liked the book.
You are making a habit of "asking before reading", I see? On p. 10, we explain how we dealt with mapping of alien species/populations. If you map every single alien population, you end up with a map that clouds the representation of the natural range of a species. You could solve that by using colours or shading to distinguish between natural and alien range parts, but then we would have to have accurate data on all alien populations. This data is lacking. Collecting it and presenting it in a fieldguide falls imho outside of the scope of such a book.
I liked the book! I read first pages here https://books.google.pl/books?id=OnicDA ... es&f=false before buying that book. I already surmised that introduced populations are not mapped because of difficulty in establishing bonduaries of distribution of these populations. My stepsister thought that the drawings were actual photos. She would like Ilian to draw her cat.
