Abstract

Tumbuhan pionir merupakan tumbuhan yang menginvasi dan tumbuh pada awal suksesi suatu ekosistem yang mengalami gangguan, seperti kebakaran atau tumbangnya pohon besar. Tumbuhan ini berperan penting dalam memulihkan ekosistem, menyediakan naungan bagi spesies lain, serta melindungi tanah dari erosi akibat curah hujan. Penelitian ini bertujuan untuk menginventarisasi jenis-jenis pohon pionir di Taman Wisata Alam (TWA) Batuputih, Kota Bitung, yang dilakukan pada Desember 2023 – Mei 2024. Metode yang digunakan adalah survei eksploratif dengan penjelajahan di area terganggu untuk mencatat spesies pionir yang ditemukan. Hasil penelitian mengidentifikasi lima jenis pohon pionir utama, yaitu anggrung (Trema orientalis), kiacret (Spathodea campanulata), sosoro (Dendrocnide microstigma), sirih hutan (Piper aduncum), dan mahang (Macaranga tanarius). Anggrung, kiacret, dan mahang memiliki peran penting dalam menyediakan lingkungan yang sesuai bagi suksesi ekosistem hutan. Sosoro sering ditemukan di area dengan gangguan alami, seperti pohon tumbang, sementara sirih hutan lebih banyak dijumpai pada fase awal hutan sekunder. Selain itu, sirih hutan dimanfaatkan oleh monyet yaki (Macaca nigra) sebagai sumber pakan. Hasil penelitian ini dapat menjadi referensi dalam pengelolaan kawasan konservasi serta strategi restorasi ekosistem berbasis spesies pionir.

Abstract

The Sulawesi Palm Civet (Macrogalidia musschenbroekii) is the only endemic carnivore on Sulawesi and a key mesopredator within Wallacean forest ecosystems. Despite its conservation significance, empirical information on its population dynamics and habitat associations remains limited. This study analyzes four consecutive years of camera‑trap monitoring (2021–2024) in Bogani Nani Wartabone National Park to evaluate occupancy patterns, environmental drivers, and temporal activity. Using a Bayesian dynamic occupancy framework, we estimated annual occupancy (ψ), detection probability (p), colonization (γ), and local extinction (ε), while examining the influence of elevation, slope, and additional landscape covariates. A consistent sampling effort of 49–50 cameras per year yielded 3,446–4,047 trap nights annually, with low but stable detection rates. Occupancy declined markedly from 0.86 in 2021 to 0.51 in 2024. Elevation and slope emerged as the strongest predictors of occupancy, indicating a preference for mid‑elevation forest habitats. Colonization (0.364–0.654) and extinction probabilities (0.286–0.587) exhibited high interannual variability, suggesting a metapopulation‑like dynamic influenced by habitat fragmentation and environmental instability. Temporal activity analysis revealed predominantly nocturnal and crepuscular behavior, consistent across years. These findings provide the most comprehensive ecological assessment of sulawesi palm civet to date and highlight the species’ sensitivity to habitat degradation. Long‑term monitoring, protection of montane forest corridors, and community‑based conservation programs are recommended to ensure long‑term persistence.
