Root mortality									
remarks:	data H. Persson (2000); method: Stober et al (2000)								
 	Beachstand 120B.  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 beach stand LFH-layer was measured and calculated as a mean for 2 core samples.								
 	In May97 LFH-layer was 5.98cm with standard deviation 2.40.
