Fans of Danish bacon won't be surprised to learn that there are a lot of pigs in Denmark. Although they might not be aware that pigs in Europe are also heavily concentrated in northern Belgium and the Netherlands. Fans of pizza and buffalo mozzarella might be interested to learn that European buffaloes live almost exclusively in southern Italy.
I learnt all this from Maarten Lambrechts Herds of Europe. The Herds of Europe is a series of fascinating population bubble grid maps showing the geographical distribution of farm animals in Europe. His series of static maps shows the European distribution of cows, pigs, sheep, goats and buffaloes.
Each of the maps was created in R (the R Project for Statistical Computing) and the R code for the maps is listed below the maps on Maarten's blog post.
