Growth categories of forestry land (metsätalouden maan kasvuluokat)

In Finland, forestry land is divided into three growth categories. On forest land, or productive forest, the average increment (tree growth) is over one cubic metre per year. On scrubland, or low-productive forest, this figure is 0.1–1 cubic metres and on waste land, or non-productive forest under 0.1 cubic metres per year. Forest and scrub land together are often called forest.
