Gunung Palung National Park had lost 35% of its primary forests over the past 30 years. A forest restoration program is thus vital to restore the damaged forest ecosystems. This study aims to analyze the presence of orangutan food supply and Shannon-Wiener index at Alam Sehat Lestari (ASRI) restoration site in Gunung Palung National Park. The method applies a species data collection of orangutan food (in 91 sample plots) and calculation of Shannon-Wiener index (in six 2009's plots). The result depicted approximately 65 species from 25 families found in ASRI restoration site. Eighty percent of those species indicated orangutan food.  In addition, the restoration site is believed to prevent the orangutan conflict with a human due to food availability in restoration areas for orangutans. Analysis of the Shannon-Wiener index (H') demonstrated a value of H' = 2.789, which indicated that the reforestation forest was in stable condition. The effect of increasing biodiversity as characterized by orangutan nests at restoration sites escalates the presence of wildlife.Keywords: Forest Restoration, Gunung Palung National Park, OrangutanTaman Nasional (TN) Gunung Palung telah kehilangan 35% hutan primer selama 30 tahun terakhir. Program reboisasi diperlukan untuk mengembalikan ekosistem hutan yang telah rusak. Tujuan penelitian ini adalah untuk menganalisis keberadaan pakan orangutan dan indeks Shannon-Wiener di area reboisasi yang dilakukan oleh Yayasan Alam Sehat Lestari (ASRI) di kawasan TN Gunung Palung. Metode yang digunakan adalah monitoring terhadap 91 plot untuk identifikasi pakan orangutan dan 6 plot penanaman tahun 2009 untuk perhitungan indeks Shanon-Wiener. Hasilnya terdapat 65 spesies dari 25 suku yang ditemukan di lokasi reboisasi ASRI. Sebanyak 85% dari spesies tersebut adalah pakan orangutan. Selain itu, keberadaan area reboisasi membantu mencegah konflik ini karena orangutan dapat mencari makanan di area reboisasi. Analisis indeks Shannon-Wiener (H’) didapatkan nilai H’ = 2,789, yang menunjukkan hutan hasil reboisasi berada dalam kondisi menengah atau stabil. Efek peningkatan biodiversitas ditandai dengan sarang-sarang orangutan ditemukan di lokasi reboisasi dan keberadaan satwa liar telah meningkat. Kata kunci: Gunung Palung, Orangutan, Restorasi hutan

Abstract: Direct seeding is a technology that reduces the costs of forest restoration projects and favors species which are difficult to establish for seedlings. The seeds osmotic treatment to accelerate and standardize germination and induce tolerance to environmental stresses may favor seedling establishment in field through direct sowing and contribute to the greater efficiency of this technique. With the purpose of favor seed germination and seedling establishment under direct seeding conditions in the field, Tabebuia roseoalba osmoprimed seeds in polyethylene glycol (PEG) solution and unconditioned seeds were treated with isolated and/or combined solutions of plant growth regulators (PGR) and rooting (RTG). These seeds were submitted to germination test and evaluated for percentage germination rate, germination speed index and normal seedlings, and to seedling emergence test by direct field seeding. RTG had a toxic effect on T. roseoalba seeds. Osmoconditioning induced stress tolerance by RTG during germination and on seedling establishment. PGR treatment favors seedling emergence in field conditions and alleviates the toxicity effect caused by RTG. These treatments have great potential for use in direct sowing of T. roseoalba seeds.

Plant recruitment in tropical forests reflects the chance that seeds arrive at a site resulting in seedling establishment. To inform tropical forest restoration, we ask how seed and seedling densities differentially affect dispersal and establishment limitation in successional habitats in a tropical agricultural landscape. Methods: In Los Tuxtlas Biosphere Reserve, we calculated indices of dispersal and establishment limitation using data on seed rain and seedling establishment in old-growth forest, secondary forest, and fenced pasture. We present an index that considers variations in dispersal- and establishment-limitation including density-weighted calculations. Results: There were greater dispersal and establishment limitations in pasture than in forests. Substantial differences in both dispersal and establishment limitation occurred among the 33 species for which seed and seedling data were available. Only 5% of all species had mid to low limitation in both dispersal and establishment. In contrast, 60% of all species showed high dispersal and establishment limitation. Plant recruitment in pastures is impeded by low seed arrival, given that 77% of the recorded species showed extremely high dispersal limitation (>90%). Conclusions: The low capacity of most species to arrive, seeds to germinate and seedlings to establish in pastures slow down succession back to forest.
