| description | Quantitative ecological research is needed as a baseline in the future construction and development of botanic gardens. This study aims to acquired the vegetation data in the forest area where a botanic garden will be established and analyse it quantitatively. The study was conducted using the quadrat plot (PU) method, with a plot measuring 20 m x 20 m for observation and tagging of all trees and saplings, as well as 2 mx2 m for observation of the understorey level. Data analysis was performed by utilising the importance value index, Shannon-Wiener diversity index, similarity index, cluster analysis, and principal component analysis (PCA). Plant communities in Pilan Forest were dominated by Magnolia montana(Blume) Figlar and Arenga pinnata(Wurmb) Merr. at the canopy level and Daemonorops sp. in the understorey level. The diversity index was moderate and low respectively, while the similarity index was mostly low. The clustering results showed the formation of two subsets in both growth rate as the PU VI was outside the cluster and the PCA indicated that each plot supports different plant species. The study results concluded that the composition of vegetation at Pilan forest is approaching the maximum diversity, and is relatively undisturbed due to its status as a sacred forest. Factors thought to affect the different composition of plants in each plot was the pH of the soil, the intensity of sunlight, dominant tree species, edge effects and distribution of seeds by animals. |
