Plant species from coal mine overburden dumping site in Satui, South Kalimantan, Indonesia

Abstract

Coal mine overburden (OB) materials were nutrient-poor, loosely adhered particles of shale, stones, boulders, and cobbles, also contained elevated concentration of trace metals. This condition cause OB substrate did not support plants growth. However, there were certain species that able to grow on overburden dumping site. This investigation sought to identify plants species that presence on coal mine overburden. The research was conducted on opencast coal mine OB dumping site in Satui, South Kalimantan. Vegetation sampling was carried out on six different ages of coal mine OB dumps (7, 10, 11, 42, 59 and 64 month) using line transect. Species identification used information from local people, AMDAL report of PT Arutmin Indonesia-Satui mine project, and website. There were 123 plant species, consisted of 79 herbs (Cyperaceae, Poaceae and Asteraceae), 10 lianes, bryophyte, 9 ferns, 10 shrubs, and 14 trees. A number of Poaceae, i.e., Paspalum conjugatum, Paspalum dilatatum, and Echinochloa colona generally present among the stones, boulders, and cobbles. While Cyperaceae such as Fimbristylis miliaceae, Cyperus javanicus, Rhyncospora corymbosa and Scleria sumatrensis most often found in and around the basin/pond with its smooth and humid substrate characteristics. Certain species of shrubs and trees have been present on the 7 month OB dumping site. They were Chromolaena odorata, Clibadium surinamense, Melastoma malabathricum, Trema micrantha, and Solanum torvum (Shrubs), Ochroma pyramidale and Homalanthus populifolius (trees). This plant species could be used for accelerating primary succession purpose on coal mine overburden dumping site. Nevertheless, species selection was needed to avoid planting invasive species.

“…On the other hand, A. conyzoides, P. maximum, C. mucunoides and C. odorata were the most commonly found species in the study area. In line with previous studies, these species have been reported in various coal mining sites (Sánchez-Pinzón et al, 2010;Komara et al, 2016;Novianti et al, 2017;Yusuf and Arisoesilaningsih, 2017;Igwenagu et al, 2019;Hapsari et al, 2020). The frequent occurrence of these species in polluted sites might be due to their invasive nature (Borokini, 2011).…”

“…Perhaps, these activities may have influenced the concurrent colonization of the coal dumpsites by different invasive plant species, which resulted in the continuous disruption of vegetation. Previous studies have recorded several invasive plant species present in the coal mine dumpsites undergoing rehabilitation in different parts of the world, e.g., Columbia, India, and Indonesia (Sarma, 2005;Hazarika et al, 2006;Sánchez-Pinzón et al, 2010;Ekka and Behera, 2011;Singh, 2011;Komara et al, 2016;Novianti et al, 2017;Yusuf and Arisoesilaningsih, 2017;Hapsari et al, 2020). Together, those studies identified associated plant species such as Adiantum sp., Ageratum conyzoides (Mill.)…”

Managing and Reforesting Degraded Post-Mining Landscape in Indonesia: A Review

“…OB materials are structureless with high bulk density due to the movement of heavy machinery and often contain an elevated concentration of traced metals. Their characteristics hamper water circulation, limiting their capability to support the growth of plant roots [53,54]. Therefore, sowing topsoil over the arranged OB materials will serve as a growing medium for revegetation plants [55,56].…”

“…The adaptability of an individual tree species to the habitat conditions in reclaimed land and its ability to change the soil substrate characteristics is important to determine the optimal restoration strategies [54,[109][110][111][112][113][114]. Considering the differences in their adaptability to a reclaimed site characteristic, tree species are classified as pioneering, target, climax, or late-successional species [111,115].…”

“…Meanwhile, in grassland dominated by Imperata cylindrica in Katingan District, Central Kalimantan Province, S.ciliaris was also the second dominant species (Usmadi et al 2020). S. bancana (synonym of S. ciliaris) was also found in coalmine overburden dumping site in Satui, South Kalimantan Province (Novianti et al 2017). Another sedge, Actinoscirpus grossus or Scirpus grossus, was also found abundant in some open space in the swamp with an importance value of 10.58, ranked 5 th among the ground cover species (Table 2; Figure 5).…”
