The aim of the thesis is determination of basic density of Norway Spruce (Picea abies (L.) Karst.) growing on slope with different tilt. The other matter to find out is the avarage width of the ring according to studied area. Forest in Soběnovská vrchovina is at an altitude of 775 m a. s. It was taken segments from 45 trees divided into tree studied areas according to tilt of slope by Pressler auger. For determination of basic denstity was used method by Olsen. The results offer the notion of influence of slope on basic density of Norway spruce. The detected avarage width of rings help this thesis. |
