“…In the first planting phase, pioneer plants (i.e., Melaleuca cajuputi, Cassia siamea, Acacia mangium, Acacia auriculiformis, Pterocarpus indicus, Enterolobium cyclocarpum, Adenanthera pavonina, Samanea saman, and Delonix regia) were planted with a spacing of 4x4m and 4x6m. Research by Pamoengkas et al (2020) found that 4x6m spacing resulted in better height and diameter for woody plants, S. leprosula. As for M. cajuputi (eucalyptus), a spacing of 3x3m is sufficient because it has a light canopy.…”

Abstract. Yuningsih L, Hearmansyah, Ibrahim E, Marsi. 2021. Diversity, structure and composition of vegetation in post-coal mining reclamation area in Sumatra, Indonesia. Biodiversitas 22: 3392-3400. The majority of coal mines are operated through an open-pit system which has a significant impact on the environment. Therefore, reclamation and revegetation activities are required to recover ecological sustainability. This study aimed to analyze the diversity, structure, and composition of vegetation resulting from the post-mining revegetation process in a mining concession in Sumatra, Indonesia at various intervals of post-reclamation periods, namely 11 years, 10 years, 8 years, and 5 years. Data collection was conducted by sampling with a 2.5 percent intensity. The study discovered 23 species of naturally grow understory plants and 25 species of woody plants. The stand structure at the eleventh, tenth, and eighth years of revegetation resembled an inverted J curve. The Species Richness Index (R) was determined to be low, the Shannon diversity index (H’) was is low to moderate, whereas the evenness index was moderate to high. We concluded that the structure of vegetation in the post-mining reclamation region resembled that of a natural forest ecosystem, yet the biodiversity indicators remain low and below those of natural forest. We expected the result of this study can enrich the limited knowledge of the ecology of post-mining reclamation in the tropics.

“…This competition would increase in the later developmental stages, with a denser population has higher competition and affected the availability of nutrients, light, and water [50]. Different growth performances were also observed within similar dipterocarps species affected by slopes and spacing distance [44]. Table 1 shows the performance of dipterocarps species planted at the reforested landscape with various initial conditions.…”

Gunung Dahu Research Forest (GDRF) is a 250 ha tropical degraded land reforested by native dipterocarps species. The reforestation success was valued by evaluating the planted trees’ growth performance, their potential timber stock, natural regeneration capacity, soil improvement, biological interdependence, and environmental services. This scientific report used a combination of literature review and also primary data processing to describe the reforestation success within the area. A hilly species of Shorea platyclados showed the best growth performance with its average diameter and height of 43 cm and 23 m, respectively, with its mean diameter annual increment of 2.1 cm/year and the predicted standing stock at 220 m3/ha. Six Shorea species were identified to show their natural regeneration capacity and the occurrence of ectomycorrhizal fruiting bodies, predominantly by the genus Rusula, determined the establishment of biological interdependency at the site. Reforestation improved soil organic matters as revealed by high soil porosity (51.06–52.32%) and infiltration rate (120–155.33 mm/h). The reforested landscape also ensures a continuous water supply and provides an economic benefit for the community. Thus, planting native trees for reforesting degraded tropical landscapes is prospective and may deliver multiple benefits in an ecological and economic view.

The benefits of revegetation provided by the successful growth of planted vegetations. This paper described a successful initiative on the revegetation of tropical degraded land using native trees. More than 250 hectares of intact landscape in Gunung Dahu, West Java—Indonesia have been successfully revegetated using 32 Dipterocarp species. The success of this 20-years-old revegetated landscape was revealed by timber volume, natural regeneration, soil characteristics, ectomycorrhiza occurrence, and ecotourism potential. The results showed that the average diameter and height were varied from 12–43 cm and 10–23 m; diameter mean annual increment were at 0.6–2.1 cm year−1; standing stock per hectares were at 10–220.84 m3 ha−1. The variations might be caused by different planted species, spacing distance, and planting technique. The natural regeneration success was observed by the offspring’s occurrence from six Shorea species and supported by mycorrhiza fruiting bodies predominantly by the genus Rusula. Planted trees also improved the availability of organic materials to the soils, as described by the good total soil porosity (51.06–52.32%) and infiltration rate (120–15,533 mm hour−1) at the site. The landscape also provided springs with continuous water supply and allowed tourists to experience the serenity of the tropical forest. Hence, revegetation using a native tree is prospective and proven to deliver a wider benefit in the ecological, economic, and social aspect.
