Whilst having a high forest cover is great for absorbing Co2 and provides countries such as Finland and Sweden with a productive timber industry; the limited varieties of tree species that these two countries grow causes other issues.
Monoculture forests are those which are lacking in tree species. They prevent light getting to the ground cover and the limited food on offer results in a poor habitat for woodland ecology.
Future threats of tree diseases could have huge impacts on nations which priorities growing one or two types of tree.
