How many trees per person per country?

Did you know that Canadians have more trees to enjoy per person than Russians, or that Brazilians have half as many trees per person than Australians? I hope you enjoy my interactive global map below which shows the number of trees per person per country, right around the world. But first, here are a few headlines.

Canada 8,953 trees per person

Russia 4,461 trees per person

Australia 3,266 trees per person

Brazil 1,494 trees per person

United States 716 trees per person

France 182 trees per person

United Kingdom 47 trees per person

I’ve long been interested in a research paper published a few years ago in Nature, which estimated the total number of trees in the world to be 3,040,000,000,000 (3.04 trillion). What intrigued me more was how the researchers had then mapped the distribution of trees by country across the world, and then calculated the number of trees per capita. I provide a link to the paper below. Meanwhile, I thought it would be fun to create an interactive Google map using their data. So here it is – move your mouse over the map to reveal information:

Some small countries with outlying data have been excluded from the map to improve clarity.
