Climate Action
reports a Yale University global survey of trees.

This says that there are just over three trillion trees on Earth which is eight times more than previous estimates.

Yale combined ground survey data with satellite imagery giving the new total that is equivalent to about 420 trees for every person.  About 43% (1.39 trillion trees), are in the tropics and sub-tropics, with 0.61 trillion in temperate regions, and 0.74 trillion in the boreal forests that circle the globe just below the Arctic.

The highest tree densities, calculated in stems per hectare, were found in the boreal forests of North America, Scandinavia and Russia.  The research estimates that 15 billion trees are being removed per year with only five billion being planted.
