"Kajian manfaat tumbuhan hutan pamah telah dilakukan berdasarkan data keanekaragaman dari penelitian Anas (2013), Rahmah (2013), Sehati (2013), pada bulan Februari hingga Mei 2014. Kajian tersebut bertujuan untuk mengetahui potensi pemanfaatan keanekaragaman tumbuhan hutan pamah di zona inti Taman Nasional Bukit Duabelas (TNBD). Kajian manfaat tersebut dilakukan melalui tahap pengecekan serta dokumentasi spesies terkait, dan penelusuran potensi pemanfaatannya melalui sumber rujukan ilmiah. Potensi pemanfaatan yang diperoleh sejumlah 161 spesies tumbuhan yang termasuk ke dalam 111 genus dan 48 famili. Potensi tersebut dikelompokkan ke dalam kategori bahan pangan (72 spesies), bahan obat (73 spesies), bahan bangunan (87 spesies), bahan bakar (33 spesies), kerajinan dan teknologi lokal (47 spesies), bahan pewarna dan ritual (15 spesies), dan sumber penghasilan nonkayu (20 spesies). Sepuluh famili dengan potensi pemanfaatan manfaat terbanyak adalah Euphorbiaceae (10 spesies), Moraceae (10 spesies), Lauraceae (9 spesies), Clusiaceae (8 spesies), Rubiaceae (8 spesies), Fabaceae (7 spesies), Malvaceae (7 spesies), Phyllanthaceae (7 spesies), Sapindaceae (6 spesies), Annonaceae (5 spesies).

Utilization assessment of low land rain forest vegetation was conducted based on previous research data by Anas (2013), Rahmah (2013), and Sehati (2013) on February to May 2014. Its aim was to acknowledge utilization potential of low land forest plant biodiversity at core zone of Bukit Duabelas National Park (BDNP). The assesment was conducted on checking and documentation of plant biodiversity, and economic potential assessment through scientific reference. Utilization assessment deliver 161 species in 111 genera and 48 families. Utility potential was distributed into seven utilizatition groups, food (72 species) medicinal subtances (73 species), construction (87 species), firewood (33 species), craft and local technology (47 species), natural dye and ritual (15 species), non-timber additional income (20 species). Ten highest families which mostly utilized are Euphorbiaceae (10 species), Moraceae (10 species), Lauraceae (9 species), Clusiaceae (8 species), Rubiaceae (8 species), Fabaceae (7 species), Malvaceae (7 species), Phyllanthaceae (7 species), Sapindaceae (6 species), Annonaceae (5 species)."

"Disturbances caused by the conversion of rain forests into agricultural systems provide an opportunity for the expansion of Invasive Plant Species (IPS). Bukit Duabelas National Park is one of the few remaining lowland forests in Jambi Province (Sumatera, Indonesia). The surrounding areas up to the national park borders have already been converted into jungle rubber agroforests as well as rubber and oil palm plantations which might lead to an increased spread of IPS into the forest. This study was aimed at compiling a list of IPS and determining their distribution and coverage of IPS in four land use systems (rain forest jungle rubber, rubber and oil palm plantations). Spatial distribution patterns were investigated by creating a horizontal vegetation profile diagram for the permanent plots of the EFForTS project (Ecological and Socioeconomic Functions of Tropical Lowland Rainforest Transformation Systems, http://www.uni-goettingen.de/crc990). The dominance of IPS was determined using Important Value Index. A total of forty IPS were identified across the four land-use systems. The numbers of IPS were the highest in oil palm (28 species) and rubber plantations (27 species), and the lowest in jungle rubber (10 species). IPS were absent in the lowland rain forest. The diversity of IPS was influenced by environmental factors, especially canopy openness. IPS with the highest ground coverage were Dicranopteris linearis and Clidemia hirta. Both of them were found in all three land-use systems outside the rain forest when the forest canopy opens due to illegal logging or other human disturbances. Therefore, reforestation of disturbed areas is recommended to prevent the spread of IPS."
