Therefore, it may safely be said that in the great majority of ECE countries, the area of forest and other wooded land has been stable or increasing for at least 15 years, and in most cases, since the 1950s. However this is due to a new inventory method introduced between 2000 and 2005, making 2000 data not comparable with later figures. Since 2005, the area of forest and other wooded land in Denmark is reported to have increased.
