| Popis: | Forest vegetation analysis and structure is necessary to understand in order to set up the basis of forest governance and management of the forest plan. This study aims to determine the potential, structure, species composition, and inventory of plant species of the forest stand in the educational forest, namely KHDTK Gunung Bromo. Analysis of vegetation methods on sampling plots 20 × 20 m was made in the forest area to collect trees data. The systematic sampling with the random start was used, with the plot distance 100 m. In total, there are 100 plots were measured. The results showed that total volume and tree densities were 261.66 m3/ha and 291 trees/ha. The stand was dominated by the trees with a diameter range of 20 – 30 cm. Species composition is dominated by Pinus merkusii with Species Importance Value (SIV), average volume, and density were 163.23%, 156.67 m3/ha, and 202 trees/ha, respectively. However, the sapling stage was dominated by Dalbergia latifolia that showed by SIV 119%, indicating that D. latifolia was able to regenerate itself until the sampling stage. In addition, in the seedling stage, Swietenia macrophylla was the dominant species with density 400 seedling/ha, indicating that seed was adaptive and easily spread. |
