Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 12
Abstract
The forest structure is the horizontal and vertical composition of a stand. There are many factors take part in the formation of forest structure that most important of them is genetically and environmental factors. The influence of these factors is various in different areas. For Evaluation of management, regeneration and destruction factors in forest stands, some stands with similar characteristics should be used to compare the structure of utilized and natural stands. This compare will be helpful to first save destroyed stands, second Resuscitate destroy stand and third they will be restored to the normal structure. To investigate the structure of natural stands in Baneh, two natural stand in villages Nejo and Balva selected and then plot with dimensions of 100 × 100 meter so that plots indicate the stand situation selected and implemented, then required data for study inventoried and recorded into plots. Next stage horizontal, vertical and perspective structures have been drowning. To draw the stand structure specialized software SVS (Standard Visualization System) be used, then by statistical software (Excel, SPSS), related statistics for diameter and height were also measured. The mean basal area per hectare stand of Balva and Nejo was 25.96 and 31.85 square meters corresponding, the average height was 6.1 and 5.9 meters consecutive, the ratio of crown height divided to total tree height was 0.6 and 0.5 respectively and the mean crown radius was 2 and 1.9 meter corresponding..
