“…In addition, M. malabathricum was considered dominant species on both sides, although not included as IAS, this species is potential to be invasive (Hapsari et al 2014). M. cordata was also dominant species on the younger site, it exists as a native species of IAS Mikania micrantha (Su et al 2018); however, it was reported as serious threat like IAS in reclamation site in Kintap, Tanah Laut, South Kalimantan (Yusuf and Arisoesilaningsih 2017). Further, both M. malabathricum and M. cordata were included as noxious weeds, which determined to be injurious to public health, crops, livestock, agricultural lands and other properties (USDA-NRCS 2019).…”

“…Nowadays, invasive alien species (IAS) are considered as primary threat to global biodiversity, ecosystem functions, economies and human health (Early et al 2016). It has become increasingly significant management problems in parks and reserves and frequently complicates the restoration/reclamation projects (Kabrna et al 2013;Trimanto andHapsari 2016, Yusuf andArisoesilaningsih 2017). Previously and still to some extent today, alien plant species are used in reclamation, to stabilize land and quickly develop a vegetation community (Lemke et al 2012).…”

Abstract. Hapsari L, Trimanto, Budiharta S. 2020. Spontaneous plant recolonization on reclaimed post-coal mining sites in East Kalimantan, Indonesia: Native versus alien and succession progress. Biodiversitas 21: 2003-2017. Comparative vegetation analyses subjected to recolonization of spontaneous plants were carried out in two post-coal mining reclamation sites, with different ages of reclamation, specifically 9 years old and 17 years old, in Bontang, East Kalimantan. This study aims to determine the spontaneous plant diversity and composition, identify the spontaneous alien plant species invasion (IAS), analyze the underlying micro-climates and soil factors and their association to the spontaneous plant recolonization, also to evaluate the succession progress. Results showed that both reclamation sites have undergone some vegetation and environmental improvements. The plant succession stage of both sites was identified at the same stage, as establishment phase of early-succession stage in transition to mid-succession stage. The spontaneous plants were comprised of two layers, i.e. (i) understories include grasses, ferns, lianas, herbs, shrubs and tree seedlings; and (ii) saplings include some of trees and small trees. Plant diversity indices on both sites were in moderate category. At understory layer, the 9-y.o. site was mostly dominated by grass Polytrias indica, whereas the 17-y.o. site was dominated by shrub Asystasia gangetica. At sapling layer, the 9-y.o. site was mostly dominated by Glochidion obscurum, whereas the 17-y.o. site was dominated by Macaranga tanarius. Dominant pioneer tree and shrub species in two reclamation sites mostly from general species component of secondary tropical forests from the families Euphorbiaceae, Phyllantaceae, Melastomaceae, Leguminosae, and Lamiaceae. It was recorded seven IAS in the 9-y.o. site, which six out of seven species were dominant. Meanwhile, in the 17-y.o. site was recorded eight IAS but only four species were dominant. Two dominant noxious weed species were also identified. Each IAS and noxious weed species has invasiveness traits that make them well-grown, successfully recolonized and invaded the reclamation site. Environmental factors include air temperature, air moisture, and light intensity; and soil conditions include pH, C/N ratio and physicochemical properties affected the variation of spontaneous plant establishment on each reclamation site. These comparative study findings may become inputs for coal mining operations management to evaluate and improve their reclamation program; such as by soil reconditions, controlling the populations of IAS, and planting more intensively of native tree species.

“…In erosion by water, raindrops cause soil particles to be detached from the ground and transported along the slope. The change in soil structure and removal of topsoil resulting from the erosion may cause nutrient removal and environmental degradation, thereby inhibiting plant growth [1,2]. This issue has been frequently reported in Southeast Asian countries with tropical climates [3][4][5], where squalls with high rain intensity are a major contributor to the erosion caused by water [6].…”

Effects of pH-Induced Changes in Soil Physical Characteristics on the Development of Soil Water Erosion

et al. 2018

Soil water erosion is frequently reported as serious problem in soils in Southeast Asia with tropical climates, and the variations in pH affect the development of the erosion. This study investigated the effects of changes in pH on soil water erosion based on changes in the physical properties of the simulated soils with pH adjusted from 2.0 to 10.0 through artificial rainfall tests. The zeta potential was entirely shifted to positive direction at each pH condition due to Al, Ca, and Mg. In the pH range of 6.0 to 2.0, the aggregation of soil particles resulting from the release of Al 3+ from clay minerals and/or molecular attraction between soil particles caused the plastic index (I P) of the soil to decrease. The decrease in I P led to the development of soil water erosion at the pH range. When the pH exceeded 6.0, the repulsive force generated by the negative charges on soil particles decreased I P , resulting in accelerated erosion by water. The results suggest that changes in pH causes physical properties of the soil to change through changes of the zeta potential in the clayey soil rich in Al, Ca, and Mg, leading to the development of soil water erosion.

“…The presence of this species can strangle or kill other plants. Chromolaena odorata is a perennial herb that is not tolerant to shade and able to compete with other species as it has allelopathic compounds (Yusuf and Arisoesilaningsih 2017). M. cordata, C. pubescens and C. mucunoides are understorey plants species that needs special attention because they are highly invasive.…”

Growth evaluation of native tree species planted on post coal mining reclamation site in East Kalimantan, Indonesia

Lestari DA, Fiqa AP, Fauziah, Budiharta S. 2019. Growth evaluation of native tree species planted on post coal mining reclamation site in East Kalimantan, Indonesia. Biodiversitas 20: 134-143. Mining activities affect environmental qualities including the loss of vegetation cover and the damages of physical, chemical and biological properties of soil. As such, regulations enacted by the Indonesian Government state a legal obligation for mining companies to carry out reclamation on post coal mining site. Reclamation is an activity carried out to organize, restore and improve of environmental quality after mining operations to enhance the highly disturbed ecosystem of mined land into ecologically usable state. Yet, there is little body of knowledge on how to monitor the effectiveness of reclamation in improving environmental quality of ex-mining land. Aims of this study are to evaluate of the growth of native tree species planted on various types of reclamation sites in a mining concession in East Kalimantan, and to analyze the most influencing factor of their growth. Growth parameters measured in this research were plant height, stem diameter and branch-free stem height of the planted species. Micro-climatic factors and diversity of understorey plants were also measured as environmental parameters. PCA (Principal Component Analysis) analysis was conducted using PAST 4.0. statistical program. The results shows that reclamation area of post coal mining in the study site which is most suitable for local plant species, especially Shorea balangeran, has a sloping terrain. PCA shows that factor having maximum influence on growth of planted species on the reclamation site is pH of soil. The higher is the soil pH (i.e. less acid), the better is the species growth because the soil conditions in the post-coal mining area tend to be acidic. This research suggests that in post coal mining reclamation using native trees two key factors to enhance growth performance of planted species are sloping terrain so as water is not inundated and soil pH so as it is not too acid.
