Changes in species occurrence and phytomass after clearfelling, prescribed burning and slash removal in two Swedish spruce forests
In two old Norway spruce stands, the one at Garpenberg in middle Sweden, the other at Flakaträsk in northern Sweden, the phytomass of the field- and ground-layer was measured before clearfelling and one and four years later. The phytomass of the field-layer was also measured 10 and 16 years after cl...
