Land cover by forests is directly influenced by human activity. How the forest looked like, and how much forest there was, when the European settlers arrived is difficult to ascertain as the technology only went so far as people drawing amateur maps and pictures. One could say that the amount of forests at that time and during the present are almost the same. The reasoning behind this is because we believe European settlers destroyed about 50% of the forests and we know now that 58% of forest cover has grown back. So if we are going by precise values, which these values are not, then there would be a little more forest now than there was in the time of European settlers.
