| Spatial Presentation of Diameter Class Series from the First Measurement of the Permanent Plot in “Čorkova Uvala” Virgin Forest in 1957 pdf HR EN | 363 | |
| Summary: Vertical profiles and a picture of a sample plot situated in a stand in the virgin forest of Čorkova Uvala in the Plitvice Lakes National Park were presented in “Forestry Journal” No 7–8/2007. The graphic construction was presented from a bird´s eye perspective. The goal of the published graphic presentations was to give a clear picture of the stand in the permanent plot, but we took a step further. Since tree diameter is the main factor for calculating the basal area and wood volume, we decided to distribute the trees in the stand according to diameter classes and present them from a bird’s eye perspective. The stand structure was taken from a work by Prpić (1979). The following five diameter classes were identified: – 1st diameter class up to 10 cm at breast height – 2nd diameter class from 11 cm to 30 cm at breast height – 3rd diameter class from 31 cm to 50 cm at breast height – 4th diameter class from 51 cm to 80 cm at breast height – 5h diameter class over 81 cm at breast height The picture projection of the stand structure was made separately for each diameter class (see Figures from 1 to 5). Tree distribution by diameter class is correlated with space. This includes tree structure, soil category with reference to rockiness and karst phenomena (cracks, sinkholes, rocks), terrain configuration, exposition, inclination, tree series grown in rows on rotten lying trees and others. The presented stand interpretation allows complex elaboration of its structural relationships and the life span of the tree species forming the virgin forest. | ||
