Keanekaragaman dan Pola Persebaran Jenis Pohon pada Plot yang Terganggu di Hutan Muara Talam Pulau Mursala

Abstract

Human activities such as illegal logging and forest encroachment threaten the sustainability of the forest ecosystem on Mursala Island. This study aims to identify the species composition, distribution patterns, and regeneration status in the Muara Talam forest on Mursala Island. This study uses a purposive sampling method, which involves creating plots at locations based on traces of human activity. 14 observation plots were obtained in the Muara Talam forest. The highest Importance Value Index (IVI) at the seedling and sapling levels was Syzygium acuminatissimum and Shorea atrinervosa with values of 20.33% and 26.35%. At the pole and tree levels, the highest IVI was Dipterocarpus kunstleri and Shorea acuminata with values of 72.05% and 30.75%. The biodiversity index in the Muara Talam forest for all growth stages is categorized as high. The distribution pattern shows a balance between clustered and uniform/even vegetation. The regeneration status shows that the 67 species found have different statuses. There are 19 species with a “new regeneration” status, 7 species with a “fair” regeneration status, 21 species with a ‘poor’ regeneration status, and 20 species with a “no regeneration” status. This study is expected to provide information and references on plant species, tree population distribution, regeneration status, and evaluate the impact of human activities on the Muara Talam forest, Mursala Island.
