Skogstillståndet och dess förändring i naturreservatet Lindbergska ytan i Mariestads kommun
The aim of the study is to describe the state of the forest and changes in the Lindberg nature reserve. The study area is a nature reserve with an old coniferous forest, which has not been touched since 1950. The pines in the area have a very big diameter and are 150 ? 200 years old. The spruces are up to 150 years old. 1943 became ?Lindbergska ytan? a reserve by the state forest owner and 1992 it became a nature reserve.
All trees with a diameter at breast height of 6 cm and thicker were calipered. Smaller trees are only counted. On sample trees in all diameter classes (tree number 1, 5, 10, 20, 50 and 100), age, height and the height to the first living twig have been measured.
The total volume 2004 is 2313 m3sk and there are 4616 trees in the reserve. The area is 4.27 ha, the average volume is 542 m3sk/ha, but in some small areas it is over 800 m3sk/ha.
