Root mortality									
remarks:	data H. Persson (2000); method: Stober et al (2000)								
 	Beech stand 150B. Coring was made close to five observation-windows representing 5 different trees.								
	At 4 distances from the tree 2 cores were taken and put together.								
	In the beech site there was no LFH-layer developed								
	Roots >1mm were too skattered in their distribution to give reliable results.
