“…Based on the results of the vegetation analysis, especially at the tree level, it was shown that plant density in the BTNP averaged of 447.6 individuals/ha or between 350540 individuals/ha (Kuswanda et al 2015). Kuswanda and Sugiarti (2005) reported that vegetation density in orang utan natural habitats is about 350550 trees/ha, especially at the tree level (diameter >10 cm). For this reason, the natural habitat that will be used as a release site is a forest that has plant density at the pole and tree levels above 300 individuals/ha.…”

“…The abundance index on primary and secondary forests in BTNP, when compared to other natural habitats of orang utans was higher, especially at the tree and belta levels. Kuswanda and Sugiarti (2005) stated that the abundance of plants in primary forests of orang utan habitat, such as Sibual-buali Nature Reserve (South Tapanuli) valued only of 29.2632.45. A high value of abundance index means that each species was spread uniformly and this would support stabilization for orang utans.…”

<p>The population of Sumatran orang utan in natural habitat has been declined and threatened with extinction. The orang utanreintroduction program is expected to increase breeding and population in nature. This study aimed to analyze the important value index of vegetation as well as the diversity and abundance species of Bukit Tiga Puluh National Park (BTNP) as dietary sources for reintroduced Sumatran orang utan. The research was conducted during two years from 2015 to 2016. The data collection for flora characteristics is done through the vegetation analysis with strip transects method. Plots were selected by stratification method based on the resort management and the land cover, like primary and secondary forests. Total flora species on a plot of 2.8<br />ha were identified about 301 species. The highest variation found in Suo-Suo Resort (139 species) and the lowest in Talang Lakat Resort (82 species). The dominant species have been found were Eugenia grandiflora O. Berg, Macaranga lowii King ex Hook.f., Shore iliginosa Foxw., and Tarrietia rubiginosa Kostern. Vegetation chararacteristic to be identified were tree density of 350-552.5 individuals/ha, species diversity index of 2.86-4.19, and abundance index of 32.1087.35. It also identified that vegetation characteristic among resort and land cover were different (p <0.05). Moreover, there were about 110 species of tree plants including of 31 families that found as dietary sources for orang utan and leaves became the highest plant parts which consumed by orang utans (41.8%) compared to other parts. Based on area size, ecosystem types as well as vegetation composition and variation, BTNP may support the increasing population of orang utans. However, there needs to be considered that other<br />aspects such as high human activity within the conservation area, particularly by Talang Mamak tribe communities, may cause unsuccessful achievement on reintroduction program of orang utan.</p>

“…Kawasan CADS dan hutan penyangganya merupakan habitat orangutan (Pongo abelii Lesson) sehingga kualitas dan luasan hutan primernya harus dilestarikan (Kuswanda dan Sugiarti, 2005). Orangutan adalah satwa langka yang dalam Red List of Threatened Species (IUCN, 2004) dikategorikan sebagai satwa yang kritis terancam punah secara global (critically endangered) yang sebagian besar populasinya hanya mampu hidup pada hutan primer.…”

“…Adanya kawasan hutan yang terdegradasi di sekitar CADS akan semakin menyempitkan ruang jelajah orangutan yang dapat mempercepat laju kepunahan lokal bagi orangutan. Saat ini, populasi orangutan di dan sekitar CADS hanya tersisa sekitar 27 individu (Kuswanda dan Sugiarti, 2005).…”

This research was conducted to study the tree growth and species matching in purpose of enrichment of degraded land of orangutan (Pongo abeliiLesson ABSTRAKPenelitian ini bertujuan untuk memperoleh informasi tentang pertumbuhan dan jenis tanaman yang sesuai untuk pengayaan pada berbagai tipe lahan terdegradasi yang berfungsi sebagai habitat orangutan (Pongo abelii Lesson) di daerah penyangga Cagar Alam Dolok Sibual-buali, Tapanuli Selatan. Parameter pertumbuhan (pertumbuhan tinggi, persen hidup, dan persen kesehatan tanaman) diamati pada plot seluas 0,4 ha (10 plot dengan ukuran 20 m x 20 m setiap plot), lima plot untuk setiap perlakuan pola tanam (pola jalur dan pola acak). Hasil penelitian menunjukkan bahwa jenis yang memiliki pertumbuhan tertinggi pada pola jalur adalah rambutan (Cryptocarya nitens (Blume) Koord.&Val.) sebesar 0,88cm/bulan dan pada pola acak adalah meranti (Shorea leprosula Miq) sebesar 0,93 cm/bulan. Begitu pula, berdasarkan klasifikasi tipe lahan adalah rambutan sebesar 1,2 cm/bulan (lahan kosong dan budidaya) dan durian (Durio zibethinus Murr) sebesar 0,93 cm/bulan (hutan sekunder). Jenis yang memiliki persen hidup tertinggi pada pola tanam jalur adalah durian sebesar 96% dan pada pola acak adalah medang (Litsea odorifera Valeton) sebesar 84%. Ratarata persen kesehatan tanaman pada pola tanam jalur sebesar 65% dan pada pola acak 64,9%. Hasil analisis uji t diperoleh bahwa pola tanam tidak berpengaruh terhadap persen hidup dan persen kesehatan tanaman. Jenis tanaman yang sesuai untuk pengayaan habitat pada tipe hutan rakyat sebagai jalur hijau adalah meranti (S. leprosula) dan medang (L. odorifera), pada lahan kosong atau semak belukar sebagai daerah interaksi adalah kombinasi antara tanaman penghasil kayu dengan MPTs (multipurpose tree species); dan pada lahan budidaya adalah tanaman MPTs, seperti durian (D. zibethinus), nangka (Artocarpus integra Merr), dan rambutan (C. nitens).
