Dinamika Suksesi Vegetasi pada Areal Pasca Perladangan Berpindah di Kalimantan Tengah

Abstract

Indonesia's forests is the third largest tropical forest after Brazil and Africa. However, the high rate of forest degradation in Indonesia led this country become one of the most largest contributor of greenhouse gas emissions in the world. One of the causes of the degradation of tropical forest in Indonesia is the shifting cultivation practice. The succession of vegetation after shifting cultivation practice can provide ecological services such as increasing vegetation cover and improving soil properties but takes too long to recover. This study aims to understand the dynamics of vegetation succession in the post-shifting cultivation advanced stage. This study was conducted using systematical nested sampling method to take sample of shurb and herbs, and trees, including, seedling and, sapling growth stage form three different stage of post-shifting cultivation land areas, ie young fallow (1 -10 years), intermediate fallow (11 -20 years), old fallow (> 20 years), and natural forest. The vegetation data were then analyzed using Important Value, Species Richness, Diversity and Evenness Indices. Analysis of variance with post-hoc test of DMRT assays was used if the results each vegetation indices differed significantly between stage of post-shifting cultivation land. The Species Richness and Diversity Index of shurb and herb, seedling, sapling, and tree have significantly increased (P < 0,05) except the herb and shrub communities. The Species richness and Diversity Index of tree stage of old fallow were not significantly different from natural forest but it was composed with different species.

Vegetation composition and structure across land use types in a rotational cultivation system in Meratus Mountain, South Kalimantan, Indonesia

“…In balukar anum and jurungan, the vegetation was mostly dominated by several types of pioneer species such as sungkai (P. canescens), lua (Ficus variegata), and several species of Artocarpus such as tarap (Artocarpus elasticus) and tiwadak (A. champeden). This finding is in accordance with the research by Maulana (2019) which found that young fallow lands with an age of 9 years old are dominated by pioneer plants such as Ficus spp. and Artocarpus spp.…”

Vegetation diversity and its interspecies association with merbau (Intsia bijuga) at three habitats of tropical rain forest in West Papua, Indonesia

“…Several analyses on biodiversity indicators were conducted including Margalef species richness index (Magurran 1988;Odum 1996;Maulana et al 2019), Sorensen similarity index based on Sorenson formula (1948) as in Odum (1996), Shannon-Wiener diversity index (H') (Krebs 1994;Pamoengkas et al 2018;Maulana et al 2019), and Pielou evenness index (Odum 1996;Maulana et al 2019). Analysis on interspecies relationship between merbau and other species was determined using contingency tables (Greig-Smith 1983;Maulana et al 2019) with Chi-square formula at confident interval of 5 % (Ludwig and Reynolds 1988;Sirami et al 2019). Soil analysis was conducted at the Agricultural Technology Assessment Center (BPTP) Yogyakarta to analyze soil chemistry (pH (H2O), C-organic and CEC), essential macronutrients (P and K available, Ca and Mg,) and essential micronutrients (Fe, Mn, and Zn) with total 45 samples.…”

“…The evenness index on the three sites ranged from 0.86-0.94 for seedling stage, 0.91-0.96 for sapling stage, 0.87-0.93 for pole stage, and 0.89-0.93 for trees. This indicates that the vegetation diversity in all three locations was evenly distributed since the E value > 0.6 (Maggurran 1988;Brower et al 1998;Maulana et al 2019;Fitri et al 2020).…”

Penerapan Mesin Purus Kayu Terintegrasi Sebagai Upaya Peningkatan Produktivitas Usaha Mebel

“…Sumber daya hutan di Indonesia merupakan salah satu yang terkaya di dunia. Keragaman hayati yang sangat tinggi berupa fauna dan flora merupakan uraian kebermanfaatan atas konsekuensi Indonesia sebagai negara dengan hutan tropis terbesar ketiga setelah Brazil dan Zaire (Maulana et al, 2019). Peranan sumber daya hutan ini dapat termanifestasikan dari produk yang dihasilkan.…”
