Root data									
remarks:	data H. Persson (2000); method: Stober et al (2000)								
 	Sprucestand 142S. 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 spruce stand LFH-layer was measured and calculated as a mean for 2 core samples.								
 	In May97 LFH-layer was 5.19cm with standard deviation 0.64.

Roots > 2mm									
remarks:	data from Kummetz (1996)								
	data calculated from biomass per tree multiplicated with number of trees per hectar 								
	that means: the error of these values is quite big because the distribution of the tree sizes is not taken into account
