Based on the results of research on the vegetation around Padang Lawas Temples, Padang Lawas Regency, North Sumatera Province, can be known that Padang Lawas Temple sites are located in vegetation environment of lowland tropical rain forest with a high level diversity of plant families, one of those plant families is Euphorbiaceae with one of its species, Phylanthus emlica. L(Balaka). Phylanthus emlica is a type wild plant that grows open spaces in lowland tropical rain forests. Observing its life characteristic and its habitat, then Balaka plant (Phylanthus emlica) in Padang Lawas Temples’ yards was not planted in purpose planted but grows naturally. Balaka plant (Phylanthus emlica) has different name in every area. In Melayu, this plant is known as malaka. In Minangkabau known as balaka, in Sunda known as malaka and in Java, this plant is known as Kemloko, meanwhile in Madura and Bali this plant is called mlakah ,and karsinta in Flores (NTT)


A preliminary account is given of lowland tropical rain forest in which Agathis obtusa is dominant on basaltic soils. On the islands of Erromanga and Aneityum the shade tolerant Agathis seedlings often develop in close proximity to the parent trees, usually in small canopy gaps provided by the death or deterioration of Calophyllum and other associated broadleaved trees. There is no accumulation of litter or mor humus beneath Agathis obtusa and no evidence of podzolization was found. Agathis obtusa appears to be one of the most stable components of the lowland primary forest in the New Hebrides and no windthrown trees were found. It is suggested that the emergent Agathis could moderate the effect of hurricane-force winds on the broadleaved canopy but that the smaller canopy breaks allow the growth of previously established but stagnating Agathis seedlings; similar release of Agathis regeneration has resulted from small-scale selective logging on Aneityum.

Banyak Angkrem and Kedung Kopong are medium lowland tropical rain forest areas where many types of orchids can be found. This study aims to determine the types and diversity of orchids found in the area of ​​Banyak Angkrem and Kedung Kopong. Data was collected using the Visual Encounter Survey (VES) method with a radius to the right and to the left  5 m from the observation path with a research area ​​6.24 ha. The results showed that in the two areas found 15 species of orchids consisting of 10 species of epiphytic orchids (Acriopsis lilifolia, Agrostophyllum laxum, Bulbophyllum sp 1, Bulbophyllum sp 2, Dendrobium sagittatum, Dendrobium sp, Oberonia lotsyana, Pholidota sp, Polystaschya concreta, Vanila. planifolia) and 5 species of terrestrial orchids (Geodorum densivelorum, Malaxis ophrydis, Malaxis sp, Nervilia plicata, Perystilus goodyroides). The level of diversity (H ') of orchids in the two regions is classified as moderate with an H' value of 2.22

<p>A study has been conducted in the lowland of tropical rain forest, swamps and mangroves in the vicinity of Tapormay and Aindua villages in the Far-West Mimika District from Mimika Regency, Papua Province to examine the diversity of plant and animal species and the number of plant and animal species utilized by the Kamoro tribe in the villages in they everyday life. A descriptive method with survey technique and interview to the people in Tapormay and Aindua villages were used to carry out the study. The results of the study found 36 dominant plants species in lowland tropical rain forest, five dominant species in swamp forest and nine dominant plant species in mangrove forest.  While as many of 35 wildlife species were encountered in lowland tropical rain forest, marshes and mangroves consisting of nine species of mammals/marsupials, 24 species of birds and two species of reptiles. Non-timber forest products recorded by the Kamoro in both villages were 47 species divided into 10 groups: food and beverages, household necessities, sleeping equipment and rain hood, hunting tools, medicines, oil, sources of firewood, tribe ornaments, wooden boats, and musical instruments.  Based on the level of forest importance or the most important function of forest area for the Kamoro is as a place to find food, that is: sago and hunting. Interview with all respondents (100%) stated that the main function of the forest is where to take sago followed by hunting activities, picking up firewood, wooden boats, fruits and medicines, and taking building materials and bark.</p>

Hutan kampus Universitas Jambi Mendalo merupakan salah satu hutan alam sekunder tua yang merupakan perwakilan tipe ekosistem hutan hujan tropis dataran rendah (Lowland Tropical Rain Forest) yang memiliki keanekaragaman hayati cukup tinggi. Hingga saat ini data keanekaragaman jenis pohon di Hutan Kampus Universitas Jambi Mendalo masih belum tersedia secara lengkap. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis pohon yang tumbuh di Hutan Kampus Universitas Jambi Mendalo dengan tahapan suksesi berupa hutan alam sekunder tua pada tipe ekosistem Hutan Hujan Tropis Dataran Rendah. Penelitian ini dilaksanakan di Hutan Kampus Universitas Jambi Mendalo, Desa Mendalo Darat, kecamatan Jambi Luar Kota, Kabupaten Muaro Jambi. Inventarisasi menggunakan teknik eksplorasi dengan intensitas sampling 100% (sensus), dengan  mengambil sampel vegetatif (daun, dan ranting) dan bila ditemukan diambil pula sampel generatif (buah dan Biji) dari setiap jenis pohon yang dijumpai untuk selanjutnya dibuat menjadi sampel herbarium yang akan dikirim ke Herbarium Bogoriense Bogor. Hasil dari penelitian, didapat 105 spesies pohon berdiameter di atas 10 cm yang tergolong pada 56 genus dan 35 famili meliputi beberapa famili bernilai ekonomi dan konservasi tinggi yaitu : Dipterocarpaceae (Shorea sp., Hopea mengarawan), Lauraceae (Litsea sp., Alseodaphne sp.) ,dan Thymeleaceae (Aquillaria malaccensis).
