Well, as you can see, obviously yes.
But whether there are a lot of trees or not, very many trees here depends on whether you're comparing to ancient times or more recent.
When the first Viking settlers arrived here more than a thousand years ago, vast birch forests blanketed the landscape from the mountains down to the sea.
In fact, as much as 25% to even 40% of the land was covered in trees.
But these early Iron Age settlers clear cut them, using the trees for fuel, for building ships and homes and clearing them to graze animals.
Within about 300 years, nearly all the trees were gone.
Iceland will probably never again see 40% of its landscape covered in trees.
But even reaching a 5% goal will help the country prevent erosion and increase the health of its soil.
