Abstract

This study analyzed the vegetation structure, composition, and dynamics of the beach forest in Kamarian Village, Western Seram Regency, Maluku Province. The research employed a systematic sampling method with continuous measurement plots across three distinct forest blocks, measuring vegetation parameters at four growth stages: trees, poles, saplings, and seedlings. Results revealed a well-developed four-strata forest structure (Strata A:20-29m, Strata B:4-20m, Strata C:1-4m, Strata D:0-1m) with dominant species including Pterocarpus indicus, Terminalia catappa, Cerbera manghas, and Hibiscus tiliaceus. A total of 31 plant species from multiple families were identified, with Anacardiaceae, Moraceae, Myrtaceae, and Fabaceae being well-represented. Importance Value Index analysis indicated varying ecological significance of species across growth stages and blocks. Block III demonstrated characteristics of a more mature forest segment with higher tree density (920 ind/ha) and diversity (H' = 1.06) compared to Blocks I and II. The forest exhibited active natural regeneration processes, particularly evident in Block III with 80,750 seedlings/ha, though significant regeneration bottlenecks were observed between growth stages. Shannon-Wiener diversity indices were predominantly low (H' < 1), except at the tree stage in Blocks I and III (1.02 & 1.06), indicating moderate ecological stress
