“…Pingshuo is one of the largest opencast coalmines in China, with a history of more than 30 years since the mine was built in 1985. Past research focused on the physical and chemical properties of reclaimed soil in mining areas (Guan et al 2021;Zhang et al 2015), vegetation restoration (Yuan et al 2018;Zhao et al 2017), land use changes (Zhang et al 2020;Zhou et al 2017), and land expropriation compensation (Cao et al 2018). However, relevant research on carbon emissions and sinks in large-scale opencast coalmine areas is currently insufficient, especially considering carbon peak and carbon neutrality.…”

Remote sensing image data of typical mining areas in the Loess Plateau from 1986 to 2018 were used to analyze the evolution of land use, explore the division of carbon sink functional areas, and propose carbon neutrality paths to provide a reference for the coal industry carbon peak, carbon-neutral action plan. Results show that (1) land use has changed significantly in the Pingshuo mining area over the past 30 years. Damaged land in industrial, opencast, stripping, and dumping areas comprises 4482.5 ha of cultivated land, 1648.13 ha of grassland, and 963.49 ha of forestland. (2) The carbon sink functional areas of the Pingshuo mining land is divided into invariant, enhancement, low carbon optimization, and carbon emission control areas. The proportion of carbon sinks in the invariant area is decreasing, whereas the proportion in enhancement, low carbon optimization, and carbon emission control areas is gradually increasing. (3) The carbon neutrality of the mining area must be reduced from the entire process of stripping–mining–transport–disposal–reclamation, and carbon emissions and carbon sink accounting must start from the life cycle of coal resources. Therefore, carbon neutrality in mining areas must follow the 5R principles of reduction, reuse, recycling, redevelopment, and restoration, and attention must be paid to the potential of carbon sinks in ecological protection and restoration projects in the future.

“…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].…”

“…The success of reforestation in post-mining land is determined by some factors, one of which is planting activities and the availability of planting stock [131]. The preparation of quality seedlings through plant propagation is important in post-mining land revegetation activities, especially with the use of local species, whose silvicultural techniques are usually little known [111]. For local species, generative propagation is generally chosen because it is provided in the mining area [132].…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

“…De hecho, Ayerde y López (2006) observaron que las plántulas de J. flaccida que se establecen de julio a octubre, durante el periodo de secas (febrero a marzo), presentaron un alto porcentaje de mortalidad. Por lo que ante la alta tasa de mortalidad y la escasez de individuos adultos es probable que los menos maduros, eventualmente, también desaparezcan (Zhao et al 2017). Al respecto, en un bosque de Pakistán, Moinuddin et al (1990) consignan que el disturbio antrópico repercute en las brechas de clase de tamaño y en la baja densidad de plántulas de J. excelsa, y que sin un manejo adecuado, a la larga la población de este taxón estará amenazada.…”

Juniperus deppeana es una especie tolerante a la sequía y al fuego, capaz de desarrollarse en suelos con condiciones adversas, razón por la cual se le considera una especie con potencial para la conservación de suelos. Sin embargo, en México ha sido poco estudiada, ya que no tiene un valor relevante en la industria forestal. En el estado de Tlaxcala existen poblaciones abundantes de este género, por lo que se seleccionaron las localidades El Pardo (EP) y Acopinalco del Peñón (RAP) para analizar las características estructurales y demográficas de los individuos presentes de J. deppeana; así como determinar la influencia de algunos factores abióticos. Los análisis de t de Student indicaron valores promedio significativos en la altura, diámetro mayor, diámetro menor y en la cobertura. No se obtuvo relación significativa entre las variables dasométricas con la pendiente y la orientación de las parcelas de muestreo. La relación del DAP con la cobertura fue significativa. La curva de supervivencia para ambas localidades presentó un patrón tipo III. Los análisis estadísticos confirmaron que la estructura de tamaños difiere entre los sitios de muestreo. Se deduce que el comportamiento poblacional de J. deppeana acusa una pérdida alta de individuos jóvenes, lo que supone un riesgo para su regeneración natural. Por otro lado, aunque los ejemplares en el predio sujeto a manejo forestal reúnen características dasométricas más favorables, se requiere de estudios a largo plazo bajo un enfoque más integral, a fin de determinar las posibilidades de conservación de esta especie.
