Struktur Dan Komposisi Tegakan Pada Kawasan Hutan Adat Imbo Putui
ABSTRACT
Biodiversity plays a crucial role in fulfilling the diverse requirements of living organisms. The increasing human population has led to escalating demands on forest resources, potentially resulting in extensive exploitation if not managed effectively. This necessitates implementation of management strategies and stand structure determination to prevent forest exploitation. This study aimed to analyze the stand structure and composition within the Imbo Putui Customary Forest area, Kampar Regency. The research employed Systematic Sampling with Random Start methodology, documenting individuals at four vegetation levels: seedlings, saplings, poles, and trees within designated research plots. Data analysis utilized multiple indices including Important Value Index (IVI), Species Diversity Index, Evenness Index, Species Richness Index, and Variance to Mean Ratio Index. The results identified 72 species distributed across 29 families. Lalan (Santiria laevigata) exhibited predominant dominance with IVI values of 34.91%, 44.74%, 26.49%, and 47.59% at tree, pole, sapling, and seedling levels, respectively. The forest stand structure demonstrated normal distribution characteristics, with an inverse relationship between stem diameter and frequency of occurrence.
Keywords: Stand Structure, Species Composition, Imbo Putui Customary Forest, Important Value Index (IVI), Lalan.
