Abstract

A restoration program is needed by West Lampung District, because 80% of the protected forests in this district have been damaged. Bina Wana (BW) Community Forest Group (CFG) has been successful in carrying out restoration program of 465 ha of Bukit Rigis protected forest. It resulted in an 80% increase in its members' income and an increase by 2.58% of the forest cover. To maintain the success of a sustainable restoration program, high commitment from the community is needed. This research has been conducted in June-July 2019 at West Lampung District, Lampung Province, Indonesia. The objective of this research is to analyse the social variables that affect restoration in the protection forest. The dependent variable is income and independent variables consist of respondents’ characteristics as individuals and social characteristics of the community. Based on the multiple regression linear analysis from 75 respondents, it was found that the significant variables for the sustainability of the restoration of Bukit Rigis protected forest are as follow: age, sex, education, status in CFG, distance from home to CF areas, social aids and social capital. Existence of the youth groups namely Himpunan Pemuda Peduli Hutan dan Lingkungan and Melati Women Forest Farmer Group (WFFG) plays an important role in implementing the restoration program. Establishment of HPPHL will ensure regeneration in maintaining the sustainability of restoration achievements. The role of WFFG is also important because their households’ income is supported by WFFG and enables the BW CFG members to be more concentrated in maintaining forest sustainability.

Abstract

Bird migration is a natural phenomenon that plays a crucial role in maintaining global ecosystem balance. One of the most notable groups involved in this phenomenon is migratory waterbirds, which depend on wetlands as resting, feeding, and breeding sites during their migration period. This study aims to analyze the ecological indices of migratory birds, including species diversity, richness, evenness, abundance, and dominance, across various wetland types in Sumbernadi Village, South Lampung Regency. Data were collected from November to December 2024 using the point count method at six observation points representing four wetland types: mangrove, mudflat, fishpond, and rice field. The results recorded nine migratory bird species from three families, with the highest diversity observed in mudflats (H' = 1.958) and the lowest in mangroves (H' = 0.637). The Scolopacidae family dominated in terms of both abundance and distribution. Environmental factors, including food availability, vegetation structure, and human disturbance, influenced differences in diversity among habitats. These findings suggest that the wetlands in Sumbernadi Village provide vital ecological habitats for migratory birds. Therefore, sustainable management and conservation efforts are crucial for preserving the environmental functions of these wetlands and supporting the continuity of migratory bird populations in the region.

Abstract

Protected forests are forest areas protected by law to maintain the balance of their ecosystems. The reciprocal relationship between birds and their environment can serve as an indicator of habitat condition, as birds are highly sensitive to environmental changes. The Way Rilau Research Station, situated in Lampung Province, is a protected forest that serves as a habitat for a diverse range of bird species. Therefore, the purpose of this research is to obtain data on species diversity, species richness, species evenness, and bird species dominance. Data collection in this study was conducted using a combination of point-count and line-transect methods. Observations were conducted in the morning (6–9 am) and the afternoon (3–6 pm). The results showed that 76 bird species from 37 families were recorded, totaling 382 individuals. The diversity index (H') value is 3,836, with a high category, and the species richness index (R) value is 13,370, which is categorized as high. The bird species evenness index (E) value is 0.886, which is classified as stable, while the species dominance index (C) value is 0.034, which indicates no species dominates. Based on the bird food guild type, the insectivore group dominates with 55 species (71.05%). The frugivore group with 12 species (17.11%), the carnivore group with four species (5.26%), the next dominance is the omnivore group with four species (5.26%), and the piscivore group with one species (1.32%)

Abstract

Hornbills are birds capable of flying over long distances, ranging approximately from 39 to 55 km. However, habitat loss caused by widespread forest encroachment poses a serious threat to their survival. Modeling to visualize the canopy structure of potential trees can help visualize the stand profile at the Way Rilau Research Station. The aim is to analyze the characteristics of potential hornbill nests in habitats identified as suitable for these birds. The research was conducted from December 2024 to January 2025 at the Way Rilau Research Station (SRWR), FMU Batutegi, Tanggamus Regency. Data collection uses vegetation analysis, including observations, to identify trees within a 20 m x 20 m plot. The data is analyzed using the Spatially Explicit Individual-based Forest Simulator (SExI-FS) software to model and project canopy profiles digitally and analyze dominance across all plots using the Important Value Index (IVI). The vegetation analysis identified 14 families and 24 tree species, including potential nesting trees such as Kepak, Lengsar, Pasang Merah, and Sempur. The highest Importance Value Index in this analysis was Quercus sundaicus (40.96%), followed by Dipterocarpus korthalsii (32.74%) and Corypha utan (25.03%). These results were projected as a stand profile using SExI-FS software to visualize the conditions around potential nest trees and the criteria. Based on these projections, the potential nest trees have larger crowns than the surrounding supporting trees

Abstract

Bird habitat use is closely linked to survival, reflecting reciprocal interactions between avifauna and vegetation structure within managed landscapes. Coffee monoculture, coffee-based agroforestry, and community-managed forests represent land-use systems with varying capacities to support bird communities in the Utilization Block of the Batutegi Forest Management Unit (KPH Batutegi), Lampung, Indonesia. This study aimed to assess bird species diversity, species similarity, feeding guild composition, and the influence of vegetation and environmental variables across these habitat types. Bird surveys were conducted using the point count method, complemented by quantitative analyses of vegetation structure and environmental factors. Results indicate that the highest bird species diversity occurred in forest habitats (H′ = 2.490), while the greatest species similarity was observed between forest and coffee monoculture habitats (J = 0.464). Across all land-cover types, bird communities were dominated by insectivorous feeding guilds, accounting for 55% in coffee-based agroforestry, 44% in forest habitats, and 42% in coffee monoculture systems. Multivariate regression analyses revealed that vegetation attributes (diversity and density) and environmental variables (altitude, slope, temperature, and humidity) did not exert a significant influence on bird diversity. This pattern is attributed to pervasive anthropogenic pressures, including land-use homogenization, forest modification, and ongoing human disturbance. These findings underscore the need for systematic monitoring and improved land-management practices to mitigate anthropogenic impacts and enhance the ecological function of coffee-based landscapes and forest habitats in supporting avian biodiversity.

Abstract

Desa Pematang Kuala merupakan salah satu desa di Kecamatan Teluk Mengkudu yang memiliki luas wilayah hampir 80% berupa hutan mangrove. Hutan mangrove di desa ini merupakan hutan mangrove yang dikelola secara bersama oleh masyarakat untuk memenuhi kebutuhan sehari-hari. Penelitian ini bertujuan untuk menganalisis vegetasi mangrove guna mengetahui kelestarian hutan mangrove di Desa Pematang Kuala, Kecamatan Teluk Mengkudu, Kabupaten Serdang Berdagai, Sumatera Utara. Metode penelitian menggunakan petak contoh berukuran 10x10 m² secara systematic sampling with random start, jalur transek yang diterapkan sepanjang 141,42 m. Pengumpulan data dilakukan pada 3 blok (perlindungan, pemanfaatan 1 dan pemanfaatan 2) dengan jumlah total 15 petak contoh. Hasil penelitian menunjukkan bahwa jenis mangrove yang mendominasi pada setiap blok penelitian adalah Avicennia marina, dengan nilai Indeks Nilai Penting (INP) yang tinggi di semua fase pertumbuhan (semai, pancang, dan pohon) dengan rata rata nilai INP 136,13%. Keanekaragaman jenis mangrove pada blok perlindungan lebih tinggi dengan nilai (H’) 0,80 dibandingkan blok pemanfaatan dengan nilai (H’) 0,30 akibat dipengaruhi oleh tekanan aktivitas manusia seperti perikanan, tambak, dan pembuangan limbah. Nilai indeks keanekaragaman, kekayaan, dan kemerataan menunjukkan bahwa ekosistem mangrove di lokasi penelitian masih tergolong rendah.
