Testo completoAbstract (sommario):
Rocket and spinach baby leaves are valuable commodities since they are basic components of popular ready-made salads. Two methods may follow after harvesting: establishment of new cultivations or successive revegetations and harvests. This study aimed to investigate the yield and nutritional value of rocket and spinach baby leaves after individual cultivations or successive revegetations in a floating system to improve their production strategy. The crops were cultivated in a greenhouse for seven weeks using a floating system with an adjusted nutrient solution. The leaves were either harvested and immediately replaced with a new set of plants (control) or harvested and placed again in the same tank in order to revegetate (revegetation). Revegetated rocket baby leaves in five cuts produced similar yield, with greater antioxidant capacity (DPPH scavenging activity) and total phenolic content, and greater nitrate content (eight times below the maximum allowed by EU) compared to control. Revegetated spinach produced more yield with enhanced antioxidant activity and total phenolic content and the same nitrate content compared to the control. Colour was not affected in either crop, thus eliminating the possibility for market rejection. Production efficiency was increased, as shown by the yields and the reduced resources provided in the revegetation tank. Thus, successive harvesting and revegetation are suggested for increased production efficiency and quality of rocket and spinach baby leaves.

AbstractProducers facing infestations of invasive annual grasses regularly voice the need for practical revegetation strategies that can be applied across broad landscapes. Our objective was to determine the potential for scaling up the single-entry approach for revegetating medusahead-infested rangeland to broader, more heterogeneous landscape-scale revegetation of winter annual grass–infested rangeland. We hypothesized, when applied on a highly variable landscape scale, the combination of imazapic and seeding would provide highest abundance of perennial grasses and lowest amount of annual grasses. Treatments included a control, seeding of crested wheatgrass (‘Hycrest’) and Sandberg's bluegrass, spraying (60 g ai ha−1 imazapic), and a simultaneously applied combination of spraying and seeding. The HyCrest and Sandberg's bluegrass seeding rates were 19 and 3.4 kg ha−1, respectively. The treatments were applied to large plots (1.4 to 8 ha) and replicated five times, with each replication located in different watersheds throughout southeastern Oregon. This study shows that the single-entry approach can be scaled up to larger landscapes, but variation within establishment areas will likely be high. This procedure should reduce the costs over multientry treatment applications and make revegetating annual grass–infested rangeland across landscapes more affordable.

The use of grasses native to New Mexico are preferred for revegetating Albuquerque's sewage sludge disposal site. A greenhouse study was conducted to determine the most appropriate grass species that could be used in revegetation. Nine grasses grown in soil collected at Albuquerque's sludge disposal site were compared based on germination measurements, including plant height and density. Final shoot and root weights also were taken for comparison. Plant tissue was analyzed for the accumulation of metals and salts. With 200 ml of water applied weekly, plant height was greatest in spike dropseed (Sporobolus contractus A. S. Hitchc.) at 33.86 cm; plant density was greatest in alkali sacaton (Sporobolus airoides Torr.). Results indicate the grasses that have the best potential for use in revegetation are blue grama [Bouteloua gracilis (H.B.K.) Lag. ex Griffiths], sideoats grama [Bouteloua curtipendula (Michx.) Torr.], and alkali sacaton.

Testo completoAbstract (sommario):
Revegetation plantings are a key management tool for ecological restoration. Revegetation success is usually measured using ecological traits, however, genetic diversity should also be considered as it can influence fitness, adaptive capacity and long-term viability of revegetation plantings and ecosystem functioning. Here we review the global literature comparing genetic diversity in revegetation plantings to natural stands. Findings from 48 studies suggest variable genetic outcomes of revegetation, with 46% demonstrating higher genetic diversity in revegetation than natural stands and 52% demonstrating lower diversity. Levels of genetic diversity were most strongly associated with the number of source sites used—where information was available, 69% of studies showing higher genetic diversity in revegetation reported using multiple provenances, compared with only 33% for those with lower diversity. However, with a few exceptions, it was unclear whether differences in genetic diversity between revegetation and natural stands were statistically significant. This reflected insufficient reporting of statistical error and metadata within the published studies, which limited conclusions about factors contributing to patterns. Nonetheless, our findings indicate that mixed seed sourcing can contribute to higher genetic diversity in revegetation. Finally, we emphasize the type of metadata needed to determine factors influencing genetic diversity in revegetation and inform restoration efforts.

Testo completoAbstract (sommario):
It has been suggested that revegetation in agricultural areas to tackle land degradation problems can also aid in the conservation of biodiversity in these regions. Native biota is restricted to remnant areas, which are mostly small, often unconnected, and subject to a variety of impacts from the surrounding altered landscape. The current remnant network is not sufficient to ensure the long-term persistence of the biota, and requires enhancement. Revegetation provides an opportunity to protect and add to the existing remnant network. However, there are few data available with which to assess the likely impact of revegetation on conservation values, and few guidelines as to how revegetation should be designed for conservation purposes. This paper presents an initial framework for developing revegetation strategies which tie into the existing conservation network. Revegetation can either provide buffer strips around existing remnants to protect them from external impacts, corridors between them to increase connectivity, or additional habitat to increase the area of vegetation available, or can enhance degraded remnant areas. Precise design principles and specifications for these types of revegetation are lacking, and may not be appropriate since they will depend on vegetation types and the requirements of target species. In addition, revegetation will help retain biodiversity indirectly if it helps stabilize an otherwise degrading agricultural landscape. Revegetation in agricultural areas is compared with minesite rehabilitation, where the redevelopment of functioning ecosystems and faunal habitat appears to be possible. The task is harder in the agricultural situation because the scale of modification is greater, soil changes are more difficult to redress, and recolonization by native species is less likely. Increased research effort is needed on the implementation and effects of differing types of revegetation, strategies for increasing rates of adoption of revegetation and methods of integrating conservation considerations into revegetation programmes.

Reclamation for aspen revegetation in the Athabasca oil sands: Understanding soil water dynamics through unsaturated flow modelling. Can. J. Soil Sci. 92: 103–116. Reclamation of mined areas in the Athabasca oil sands region is required by law, with the ultimate goal of revegetating to species characteristic of predisturbance native plant communities. To develop adequate reclamation strategies, an analysis of soil water dynamics is of utmost importance, as is understanding the impact of the thickness of the reclamation cover. In this work, soil water dynamics and fluxes at the water table were simulated for three reclamation scenarios and compared with the fluxes obtained for natural conditions assuming that aspen is the target reclamation species. According to the simulations, a reclamation thickness between 0.5 and 1.0 m can be used to provide water for revegetation. The numerical simulations show that the reclaimed landscapes have fluxes at the water table that exhibit less fluctuation than natural conditions. To limit the interaction between the water table and atmospheric fluxes, and to limit upward flux, the water table should be deeper than 2.0 m on reclaimed landscapes that use aspen for revegetation, particularly when reclamation takes place during a dry climatological cycle.

Testo completoAbstract (sommario):
Here, we review the literature to evaluate seagrass revegetation projects focussed on Posidonia australis and Amphibolis antarctica, the main affected species in Shark Bay in the World Heritage Area in Western Australia, together with projects from Florida Bay, an analogous system with a long history of seagrass revegetation. We assessed the effectiveness of anchoring planting units, plant-unit density and size on planting-unit survival. We found no positive trends in our assessment, suggesting that there is no discrete technique, approach or technology that could be used with confidence to deliver cost-effective, scalable revegetation. Of concern was that revegetation success was evaluated over comparatively short time frames (1–3 years), driven by the strict time frames or deadlines of governing grant funding and commercial activities, leading to concerns that long-term revegetation outcomes may be difficult to assess with confidence. Several factors influenced revegetation outcomes which were grouped into three ‘filter’ categories; abiotic, biotic and socioeconomic. We recommend that future revegetation programs involving seagrass have greater emphasis on understanding how these filters act independently or collectively to drive successful revegetation as well as developing cost-effective, proven and scalable technology supported by longer-term monitoring to ensure revegetation programs do achieve the desired ecological outcomes.

Peat revegetation is an effort to reduce the rate of areas reduction and the decreasing of storing capability of carbon and to restore the ecological function of peatlands. The purpose of this study was to analyze the cost components of peatland revegetation activities and to analyze the cost of each peat revegetation activity component. The research location taked place in 2 (two) villages, Haur Gading District, HSU Regency, South Kalimantan. The components of revegetation costs were grouped into: transportation costs, tools and mateials, payment and other costs. Data obtained from surveys and field observations and interviews. The data analysis used were a tabulation matrix and a comparison of each cost component for revegetation activities from the 2 compared villages. The total cost of Village A peatland revegetation activities is 10,851,018/ha. The characteristics of the community in Village A are very participatory and willing to cooperate with outside parties so that revegetation activities in this Village run well. The very high value of mutual cooperation and the desire to put common interests first became the basis for their actions. Village B revegetation activity costs Rp.12,117,883.00/ha. The very large costs involved in the procurement of seedlings due to the addition of 3,500 seedlings/21ha as replacements for dead, damaged or lost seedlings. The difference in the cost of revegetation activities is IDR 1,266,865/ha. This shows that a high level of participation and cooperation is able to reduce the cost of revegetation of peatlands.

Summary In mountain regions, the likelihood of mudflows might increase due to climate change. Although mudflows are common worldwide and devastate agricultural land, virtually nothing is known about the revegetation of mudflow deposits for agricultural purposes. To provide recommendations for rapid revegetation of mountain pastures, 52 permanent plots (4 m × 4 m) on 20 revegetated mudflow deposits in the Nature Park Sölktäler were established. We evaluated different revegetation measures (seed addition alone or combined with application of straw, lime or cattle manure) two years after sowing using commercial clover-grass seed mixtures. Furthermore, 27 permanent plots on 15 unsown mudflow deposits were surveyed. Sowing seeds can considerably accelerate revegetation on siliceous mudflow deposits. Festuca rubra, Agrostis capillaris, Lolium perenne, Trifolium repens and Lotus corniculatus are particularly suitable for rapid grassland reestablishment, whereas Poa pratensis is not recommendable. A pure straw application should be avoided because it delays the revegetation success. Lime addition is not recommended because it can lead to an undesirable legume dominance if clover-grass seed mixtures are used for revegetation. The most effective measure for large-scale revegetation seems to be seed addition without additives. To facilitate revegetation on coarse-grained deposits, large rocks should be crushed using a stone mill.

Abstract Many revegetation activities have been carried out on post-mining land in Indonesia and have produced various positive impacts on the land. This raises a question that what changes have occurred in various post-mining areas that have been revegetated in Indonesia. The method used a literature review from 37 sources (Journals and research report) related to the impact of revegetation activities in various post-mining lands in Indonesia. The results of this literature review conclude that revegetation in Indonesia greatly affects and has changed 3 main aspects of a land, namely (1) soil conditions both chemically, physically and biologically, (2) improvement of nutrient cycles in revegetation areas and (3) improvement of hydrological cycles and microbial and animal habitats. Suggestions that revegetation activities continue to be carried out and their success monitored and revegetation cooperation with the community will be more profitable.

The purpose of the study was to analyze the development of vegetation succession in the post-coal mining revegetation area of PT Amanah Anugerah Adi Mulia. The method used to collect data in the revegetation area is the Nested Sampling. The data collected in the form of individuals number, types of vegetation, and diameters of poles and trees. Data were analyzed by tabulating matrix and Indeks Nilai Penting (INP). There are 8 main types of revegetation plants, 16 types of natural growth and 40 types of undergrowth plants. There is a trend of increasing the number of plants that grow naturally at the level of seedlings, saplings, poles and trees in the revegetation area. Revegetation plants aged 7 years had the highest number of species. The dominant species at 1 year revegetation age for seedlings was sengon buto (Enterolobium cyclocarpum) with INP= 86,01%, sapling was E. cyclocarpum with INP= 106,15%. The dominant species at 3 years of revegetation age for seedlings was calliandra (Calliandra calothyrsus) with INP value = 75,57 %, sapling was sengon laut (Paraserianthes falcataria) with INP = 56,73%, pole level was P. falcataria species with INP = 162,85%. The dominant species at 5 years of revegetation age for seedlings was sisir liar (Cudrania cochinchinensis) with INP value = 108,38 %, sapling was C. cochinchinensis with INP = 103,59 %, pole level was mangium (Acacia mangium) with INP = 229,58 %, the tree level is mangium with INP = 211,74%. The dominant species at 7 years of revegetation age for seedlings was mahang (Macaranga gigantea) with INP value = 53,32%, sapling was M. gigantea with INP = 44,31 %, pole level was A. mangium with INP = 98,29 % , the tree level is P. falcataria with INP = 163,15%. Revegetation can facilitate the succession process in post-mining land.

Revegetation can trigger a succession process in post-mining land. The success of revegetation can be assessed by increasing the natural species in the revegetation area. The research objective was to analyze the natural regeneration of mines from several revegetated areas with different planting ages (2 years, 4 years, 6 years, and 8 years). The research was conducted in the post-coal mining revegetation area of PD. Baramarta, Sungai Pinang District, Banjar Regency, South Kalimantan. Data collection was carried out using the nested plot method by making 6 plots measuring 20m x 20m. The data collected were the number of species, the number of individuals and the diameter of poles and trees. Data analysis used tabulated matrices and Importance Value Index. The results showed there were 11 plant species in the revegetation area, 7 natural plant species, 3 main plant species and 1 secondary plant species. Natural vegetation regeneration is only found at the seedling and sapling level. L.indica and C. longifoliium, based on Importance Value Index, are natural vegetation types that dominate the vegetation structure of revegetation areas. Main plant types A.mangium and P. falcataria are able to regenerate naturally. Limited habitat in post-coal mining areas has limited natural regeneration in revegetation areas. Increasing the diversity of revegetation plant vegetation can be done through enrichment planting

Abstract Understanding the effects of vegetation on soil moisture is vital to the ecosystem restoration in water-restricted areas. For this study, the effects of introduced revegetation and natural revegetation on soil water (0–1.8 m) were investigated in the Chinese Loess Plateau, which was based on an in situ vegetation removal experiment and two years of soil moisture monitoring. The results indicated that under introduced revegetation, pasture grassland had lower soil moisture but higher temporal variations over the growing season. Compared with abandoned farmlands and native grasslands under natural revegetation, pasture grasslands revealed greater negative effects on deep soil moisture (1–1.8 m), which was difficult to recover following soil desiccation. In contrast, for abandoned farmlands and native grasslands, the surface soil moisture (0–0.4 m) was mainly impacted, which was easily replenished through rainfall events. These outcomes implied that natural revegetation, rather than introduced revegetation, should be the first choice in water-limited regions toward the rehabilitation of degraded ecosystems.

Testo completoAbstract (sommario):
Context Provision of key habitat resources is essential for effectively managing species that have specific ecological requirements and occur in production landscapes. Threatened black cockatoos in the jarrah (Eucalyptus marginata) forest of Western Australia have a wide range, so their conservation requires support from all land tenures, not just reserves. Mining in the jarrah forest temporarily removes cockatoo feeding habitat, so it is important to understand how cockatoos exploit revegetated areas for food resources. Aims We aimed to determine whether there were successional patterns in cockatoo feeding activity in revegetation aged from 4 to 23 years at three mine sites in the jarrah forest in south-western Australia. Methods We surveyed 232 plots in revegetation to document (1) structural and floristic variation in vegetation across mine sites and revegetation ages, (2) differences in cockatoo feeding activity across mine sites and revegetation ages on the basis of feeding residues and (3) any edge effect reflecting preferential use of vegetation at the interior or exterior of mine pits. We also documented the frequency of occurrence of cockatoo food plants and feeding residues in 480 plots in unmined forest to compare with revegetated areas. Key results Marri (Corymbia calophylla) and jarrah were commonly consumed in unmined forest and Banksia and Hakea species were also fed on to a lesser extent. Revegetated mine pits provided food within 4 years and continued to do so up until the oldest plots studied (23 years). The relative importance of food plants shifted from proteaceous species in young revegetation to myrtaceous species in intermediate to older revegetation. However, extent of feeding on myrtaceous species in older revegetation did not equate to feeding rates in unmined forest, with lower frequencies recorded in revegetation. Conclusions Black cockatoos fed in revegetation at all three mine sites, despite variations in vegetation age, structure and floristics. Feeding on proteaceous and myrtaceous food plants occurred within 4 and 7 years of revegetation being established, respectively, indicating that some food resources are restored quickly after mining disturbance of the jarrah forest. Implications Our results emphasise the importance of monitoring fauna recolonisation over appropriate time scales, to understand how successional processes in revegetation influence fauna population persistence in production landscapes.

Testo completoAbstract (sommario):
Much of Australia has extremely impoverished soil. Phosphate is particularly deficient. The major difficulty in revegetating these soils after severe disturbance is that plant survival and growth is unpredictable. Mycorrhizas are associations between soilborne fungi and the roots of plants. Of particular interest are the arbuscular mycorrhiza (AM) whose fungi form an internal colony in the roots of some 70% of all plant species. In AM, the fungi function as extensions of the root system, enabling the plant to increase uptake of non-labile minerals, especially phosphorus (P), from soil. The fungus gains its organic energy from the plant, and can only be maintained in the presence of living roots.

The research location was in the revegetation area of PT. Adaro Site Tanjung, South Kalimantan. A total of 6 measurement plots (40mx25m) were made using purposive sampling method in determining the selected measurement plots. Each measurement plot was divided into 4 measurement sub plots to measure the number of species, number of individuals, diameter and height of revegetation plants. The indicator criteria used as an analytical tool contain 6 criteria and 8 indicators. The eight indicators are the contribution of the species diversity index, growth percent, number of individuals/ha, dominance, species authenticity, canopy cover, natural introduction of new plants, and the rate of weathering of litter. The revegetation plant species assessed were Akasia (Acacia mangium), Johar (Cassia siamea), and Sengon (Paraserianthes falcataria). Data were analyzed quantitatively through scoring against the total value of the indicators or categories made. The order of priority for revegetation plants is P.falcataria (score 24 = high score), Johar (score: 23 = high score), and Akacia (score: 19 = low score).

Testo completoAbstract (sommario):
The choice of revegetating via direct seeding or planting nursery-grown seedlings influences the potential stresses suffered by seedlings such as herbivory and drought. The outcome of the balance between both revegetation methods may ultimately depend on how species identity and traits such as seed and seedling size interact with environmental conditions. To test this, we will conduct a continental-scale experiment consisting of one mini-experiment replicated by multiple participants across Europe. Each participant will establish a site with seeded and planted individuals of one or more native, locally growing oak (Quercus) species; the selection of this genus aims to favour continental-scale participation and to allow testing the response of a widely distributed genus of broad ecological and economic relevance. At each site, participants will follow the present protocol for seed collection, seeding in the field, nursery cultivation, outplanting, protection against herbivores, site maintenance, and measurement of seedling performance and environmental variables. Each measurement on each species at each site will produce one effect size; the data will be analysed through mixed-effects meta-analysis. With this approach we will assess the main effect of revegetation method, species, plant functional traits, and the potential effect of site-specific effect moderators. Overall, we will provide a continental-scale estimate on the seeding vs. planting dilemma and analyse to what extent the differences in environmental conditions across sites, seed size, functional traits, and the phylogenetic relatedness of species can account for the differences in the effect of revegetation method on seedling performance across study sites and species.

One of the biggest challenges in coal mining activities is the successful management of degraded land through post-mining revegetation activities in accordance with applicable regulations. An easy way to assess the success of revegetation can be done with the approach of the physical properties of the soil. This study aims to evaluate post-mining revegetation land management by analyzing soil physical properties in the form of permeability and bulk density associated with plant growth. The research method was carried out by taking a predetermined sample in the plot area with a size of 20 x 20 m in each revegetation land planted with three depths are 0-20 cm, 20-40 cm, and 40-60 cm. The results showed that the success of revegetation land showed a positive increase where the growth of Acacia mangium plant height had reached 56.5% and the growth of the stem diameter of the plants had reached 53.8% when compared with the same plant type on the original revegetation land (HTI) according with the physical properties of the soil in the form of permeability which shows an increase and bulk density which shows a decrease approaching the value of the HTI land conditions. Thus, the success of post-mining land revegetation can be determined by the physical properties of the soil that affect the growth of the plant.

The revegetation of steep slopes after mining and infrastructure projects is not an easy task. To enhance the effectiveness of revegetation projects, the present study aimed to review (i) specific challenges of steep slope revegetation, (ii) ecological succession patterns in similar environments, (iii) soil conditioning and revegetation strategies to enhance vegetation cover, (iv) the importance of microorganisms to enhance steep slope revegetation, and (v) the functional plant traits necessary to establish on steep slopes. In general, steep slopes are characterized by high bulk densities, potentially toxic elements, and low water and nutrient availability. Additionally, high temperature and elevated radiation constrain the soil conditioning and vegetation cover establishment. Lessons from ecological succession in natural steep slope habitats show that steep slope revegetation is a long-term process. Planting strategies, including hydroseeding and geotextiles, may enhance the implementation of vegetation cover. Different plant functional groups show adaptations necessary for establishment in steep slope environments, and mixtures of species containing different functional groups can promote diverse and resilient plant communities. Promising species may be retrieved from local rupestrian ecosystems, as these floras are adapted to shallow, oligotrophic soils. Further research on combining methods of soil conditioning with individual planting and/or seeding strategies of carefully selected species is necessary to enhance steep slope revegetation and rehabilitation, contributing to slope stability, erosion reduction, and carbon fixation in the long term.

Abstract Land reclamation and revegetation of post-mines need to be monitored regularly to ensure their progress. The drone is potential due to its high resolution and simplicity in operation and image processing. This study aimed to use the drone as an alternative in identifying and mapping land after the revegetation of coal post-mines in Tanjung Enim, South Sumatra, Indonesia. The research was conducted at the IUP Banko Barat of PT. Bukit Asam Co. Ltd, Indonesia. This research was conducted from September to December 2021. The method used in this study was a manual interpretation by making a delineation of the boundaries between types of revegetation plants in 2014, 2015, 2016, 2017, 2018, 2019, and 2020 planting years. The use of drones in this study was able to determine the distribution of revegetation plants used and produce the revegetation plant distribution map with 5 land cover classes, including Eucalyptus as the dominant species while Angsana (Pterocarpus indicus), Merbau (Intsia sp), Mahogany (Swietenia macrophylla), and Johar (Senna siamea) species with their patchy patterns, covering a total area of 22.52 ha or 66.44%. Eucalyptus is the most dominantly used as revegetation species in the coal post-mine in Tanjung Enim, with an area of 22.39 ha or 66.04% of the land. The drone is reliable for monitoring revegetation progress and may be used as a supplemental tool for evaluating post-mine conditions.

Coal mining activities in Indonesia have a negative impact on the environment. Some vegetations are disturbed even be lost especially in mining with open mine operation. Revegetation is one of activities that can improve the quality of post mining land, which are also included in post mining land reclamation activities. The purpose of this study is to analyze the biodiversity of flora in post-coal mining revegetation area and to compare the condition of vegetation in various revegetation age classes with the condition of vegetation in natural forest. Vegetation data were collected using the plotted line method in natural forest and plot method with the systematic sampling method with random start (revegetation area). The analysis found that overall conditions of revegetation area have more diverse number of species, namely 52 species woody plant species, and 23 herbaceous plant species, compared to the natural forest, which only has 46 woody plant species and 2 herbaceous plant species. Generally, diversity index and species increment in vegetation area at age more than 4 years is higher and approaching the state of natural forest than revegetation area age 0 - 2 years.

At Glen Canyon National Recreation Area (GCNRA) a number of disturbed sites require revegetation for aesthetic reasons and to maintain their natural appearace as part of the setting expected of a National Park or Recreation Area. Old road ways, decommissioned service areas, construction sites and bare areas characterize such sites. The purpose of thie project is (1) to conduct a literature review of revegetation reports pertinent to the climate and conditions of GCNRA and, (2) to extabllish two revegetation study areas at sites selected in consultation with NPS. Revegetation is necessary for functional reasons: 1) to prevent soil erosion and maintain or support the ecological balance of functioning ecosystems adjacent to the disturbed areas, and 2) to restore natural functions such as nutrient cycling, hydrology, soil stability and plant growth of the sites. Two of these sites were chosen as the location for revegetation tests.

Revegetation is the most sustainable method of soil stabilization at ski runs. In order to establish a stable plant community, it is recommended to use native species. However, non-native species are most often used. In this paper the revegetation of ski runs at two ski resorts is investigated: Divcibare and Stara Planina. Seven species were used for the revegetation of the ski run at the Divcibare ski resort of which six species were native. Six species were used for the revegetation of the Stara Planina ski resort, of which two species were native. It was established that the plant species used in the seed mixtures were suitable for erosion control at the investigated ski resorts.

Reclamation activities should be carried out after mining operation for restoring and improving the function of the land to be in better condition and productive (P.60/Menhut-II/2009). This research aims to analyze the status of the success of revegetation, based on growth ability and performance of A. mangium plants at PT Jorong Barutama Greston Block M1W; to recommend improvements for the land and plants; and to identify the cause of revegetation failure. The results of this research indicated that status of the revegetation success at Block M1W have not been categorized as successful category. The success rate were considered from the average growth percentage and health level of plants which were less than 60% (score 1, bad performance), namely 59.38% and 50.01% respectively. The improvement that could be done were soil amendment and the use of plants which are resistant to poor environment. The plants have to be resistant to acid soil and high content of heavy metal. The main causes of revegetation failure were site condition which were not conducive for A. mangium plant growth and lack of plant maintenance. This was the cause of bad plant growth performance. Besides that, Standard Operational Procedure (SOP) on revegetation activities need to be improved and plant maintenance should be enhanced, particularly those related with pest and disease control.Key words: A. mangium, evaluation, post coal mining, revegetation

Selecting optimal revegetation patterns and filtering priority areas can improve the effectiveness and efficiency of revegetation planning, particularly in areas with severe vegetation damage. However, few people include optimal revegetation patterns and priority restoration areas into revegetation plans. The Near-Nature restoration pays attention to “based on nature” ideas, guiding the degraded ecosystems to reorganize and achieving sustainable restoration through self-regulation. In this study, we conducted a field survey of the native vegetation communities in the Yanhe River catchment, and the data obtained were used to construct the potential distribution suitability of the habitat and screen the priority areas through the combination of MaxEnt and prioritizr models. We drew a heat map of species richness by simulating the potential distribution of 60 native species. The results showed that the potentially suitable habitats for forest cover were distributed in the southern part of the Yanhe River catchment; the potentially suitable habitats for herbaceous plant species were located in the center and the northwest parts of the study area; the potentially suitable habitats for shrub plant species in this area were larger than that of the forest, and herbaceous plants species were distributed in many zones of the study area. This study demonstrated that shrubs and herbaceous plant species in parts of the Loess Plateau should be considered as the pioneer plants of revegetation in future revegetation plans. Moreover, we also mapped the priority area of the Near-Nature restoration based on the richness of the potential native species. The procedure followed in this study could provide guidance for revegetation planning and manual management in the regions where vegetation damage occurs.

PT. Pertamina Hulu Rokan (PHR) is conducting activities to restore unproductive lands by revegetating in 3 types of areas. They are (1) areas of ex-well pad facilities where well plug & abandon (P&A) activities have been carried out, including the dismantling of related surface facilities, (2) areas of ex-production facilities that have been dismantled and (3) areas of ex-borrow pits. This research was conducted in PHR’s post-operation land area in 5 revegetation sites representing three types of post-operation areas, in Riau Province. The purpose of this study is to identify the types of vegetation found on post-operation land of oil and gas mining and to determine the types of vegetation that grow well on post-operation land based on the revegetation achievement target in each post-operation location in the document of Environmental Impact Analysis. Field research was conducted through the observation method. Observations were made by observing the type of plant, plant height, and plant mortality rate. The results showed that there were ten species of plants found in the 3 types of post-operation land in PHR, namely Cempedak (Artocarpus integer), Durian (Durio zibethinus), Jelutung (Dyera lowii), Jengkol (Pithecellobium jiringa), Mahoni (Swietenia macrophylla), Mangga (Mangifera indica), Matoa (Pometia pinnata), Medang (Litsea sp), Petai (Parkia speciosa), and Pulai (Alstonia scholaris). In total, the percentage of living plants was 88.2%. Furthermore, the average plant height in the five post-operation land areas was 169.8 cm. These values also indicate that the percentage of living plants and the height average of each type of plant in location is categorized as good, according to the achievement of the revegetation target in the document of Environmental Impact Analysis

Testo completoAbstract (sommario):
The effects of vegetation restoration on soil erosion resistance of gully head, along a revegetation age gradient, remain poorly understood. Hence, we collected undisturbed soil samples from a slope farmland and four grasslands with different revegetation ages (3, 10, 18, 25 years) along gully heads. Then, these samples were used to obtain soil detachment rate of gully heads by the hydraulic flume experiment under five unit width flow discharges (2–6 m3 h). The results revealed that soil properties were significantly ameliorated and root density obviously increased in response to restoration age. Compared with farmland, soil detachment rate of revegetated gully heads decreased 35.5% to 66.5%, and the sensitivity of soil erosion of the gully heads to concentrated flow decreased with revegetation age. The soil detachment rate of gully heads was significantly related to the soil bulk density, soil disintegration rate, capillary porosity, saturated soil hydraulic conductivity, organic matter content and water stable aggregate. The roots of 0–0.5 and 0.5–1.0 mm had the highest benefit in reducing soil loss of gully head. After revegetation, soil erodibility of gully heads decreased 31.0% to 78.6%, and critical shear stress was improved by 1.2 to 4.0 times. The soil erodibility and critical shear stress would reach a stable state after an 18-years revegetation age. These results allow us to better evaluate soil vulnerability of gully heads to concentrated flow erosion and the efficiency of revegetation.

This study investigated soil development resulting from revegetation in a coal mining area in northern Henan, China. The effectiveness of six distinct revegetation methods for reclaiming mine-degraded lands was assessed. These methods employed various species such as Ulmus pumila, Amorpha fruticosa, Robinia pseudoacacia, Jerusalem artichoke, and Sea buckthorn. Over a three-year reclamation period, soil development was analyzed to identify the most suitable plant species. Soil samples were collected from different depths, encompassing the topsoil (0–20 cm) and subsoil (20–40 cm) for each method and a control group. Principal component analysis was employed to evaluate the impacts of the revegetation methods on soil development. The findings show that revegetation significantly impacted soil properties, lowering pH, electric conductivity, and density while increasing moisture, organic carbon, nitrogen, phosphorus, and potassium. The effects were more pronounced in the topsoil. Among the six revegetation methods, a mixed plantation of Sea buckthorn and Amorpha fruticosa was the most effective, delivering the highest organic carbon in the topsoil at 3.23% and the subsoil at 1.32%. This study offers insights into successful mine reclamation and the advancement of green and climate-smart mining practices.

In addition to providing benefits, mining activities can result in physical, chemical, biological and marginal changes for plant growth. Criteria of plants used for revegetation of land mines are rapidly growing in the neighborhood marginal, allowing other types of grow on the land, producing fruits that are easily spread by birds, and producing a litter easier undergoing decomposition. This research aims to know the biodiversity and natural vegetation types of suitability identification for revegetation land post-mining tin. Observation of post-mining land was carried out to identify the physical and chemical properties of the soil and the type, density, and distribution of vegetation in the observation plots. Analysis of the suitability of vegetation types with rehabilitation land refers to the criteria in Permenhut No P.4/Menhut-II/2011 with modifications. Soil texture on former tin mining land was dominated by sand, is acidic, and has low nutrients. There were 35 types of plants found, ten species of trees and three types of shrubs among them, which have the potential to be used in revegetating post-tin mining land, namely. i.e., the Acacia mangium, Syzygium buxifolium, Syzygium racemosum Blume, Schima wallichii, Trema orientalis, Eugenia sp., Alstonia angustifolia, Ficus padana, Alstonia scholaris, Vitex pinnata L, Syzygium sp, Melastoma malabthricum dan Melastoma polyanthum.

Testo completoAbstract (sommario):
The need for practical revegetation strategies for managing medusahead-infested rangeland is substantial and unmet. Our objective was to test the potential for using the single-entry approach (simultaneous application of herbicide and seed with one entry) developed for other invasive-weed infested systems for revegetating medusahead-infested rangeland. Since areas infested with medusahead are frequently burned and burning may help control medusahead and provide a more suitable seedbed for desired species, we also tested the single-entry approach in conjunction with burning. Our primary hypotheses were that (1) the combination of imazapic and seeding would provide best establishment of desired species and (2) burning would enhance the efficacy of imazapic on medusahead and enhance seedling establishment. Treatments included three seeding rates (none, 13.2, or 25.0 kg ha−1 of an even mixture of all species), two herbicides (0 and 52 g a.i. ha−1 imazapic; with and without), and two burning regimes (burned, not burned) applied mid-October 2006 on two sites. In late July, 2008 through 2010, plant density and biomass were sampled. We found that the simultaneous application of imazapic and seeding resulted in establishment of desired species where they were absent. Imazapic application without seeding increased perennial bunchgrass density where enough residual plants existed before treatment. Burning tended to improve the control of medusahead with imazapic and promoted desired species. Even though follow-up treatments may be necessary, applying imazapic and seeding in a single-entry approach may provide a more practical initial revegetation strategy than multi-entry approaches on rangeland devoid of desired residual species. This procedure should reduce the costs of treatment application and make revegetating annual grass-infested rangeland more affordable.

Testo completoAbstract (sommario):
Afforestation in the Three North Region (TNR) of China has received wide concern due to the low survival rate and threats to water security associated with the lack of available precipitation for vegetation. It is crucial to provide a spatial layout for revegetation according to the available precipitation to achieve the vegetation cover target. This study investigated the spatial pattern of precipitation, determined the suitable vegetation distribution based on the ecological water requirements and precipitation, and proposed an optimized revegetation scheme by comparing the actual and suitable vegetation patterns. The results indicated that the actual vegetation that matched the pixel-level precipitation accounted for 67.24% of the total vegetation area in the TNR. However, 18.50% of the actual forest, 21.82% of the actual shrublands, and 19.95% of the actual grasslands were overloaded with respect to precipitation. The total suitable vegetation area was reduced slightly compared to the actual vegetation area. There is still some potential for the revegetation of forest and shrublands, mainly those in the eastern and south-eastern parts of the TNR. The optimized revegetation area in the TNR was 3.04 × 106 km2, including a maintenance management type of 2.19 × 106 km2, an upgrade type of 0.49 × 106 km2, and a degradation type of 0.37 × 106 km2. Maintenance management (natural restoration) and transformation to vegetation types with lower ecological water requirements were recognized as important revegetation practices in the TNR. This study provides guidelines to adjust the Three North Shelterbelt Project policies based on precipitation data to reduce the negative impact of revegetation on the hydrological cycle.

The aim of this study was to identify the spatial pattern of biomass distribution in the revegetation of the post-mining area in PTVI. The nearest neighbour analysis method by comparing the distance of an individual was used to determine the spatial biomass distribution pattern in the post nickel mining revegetation area of PTVI. The nearest neighbour analysis was used to explain the distribution pattern of locations using a calculation that considers the distance, number of locations and acreage. This analysis produced a final result in the form of an index ranging from 0 until more than 1. It can be explained as NNI <1, clustered spatial pattern, NNI = 1, random spatial pattern and NNI> 1 dispersed spatial pattern. This research was found that there are clustered (K1, K2, K3) and dispersed patterns (K4) of biomass spatial distribution patterns in PTVI’s post nickel mining revegetation area.Keywords: post-mining, revegetation, biomass, spatial distribution pattern

Testo completoAbstract (sommario):
Russian-olive is a nitrogen-fixing tree invading riparian corridors in western North America. The premise of revegetation after weed removal is that revegetation is required to return native species to a removal site and that revegetation improves site resistance to invasion or reinvasion via competitive exclusion. Therefore, we expected that revegetation would reduce invasive species cover and increase native species cover compared with non-revegetated controls. Native understory species diversity increased with time since removal. We recorded 18.2 native species in 2012, and 28.2 native species in 2016. Out of 22 planted species, 2 did not establish. Diversity in revegetated plots did not differ from unplanted controls, likely because species spread quickly across plot boundaries. Native perennial grass, seeded species, and annual bromes increased over time, while nonnative forbs and native forbs decreased over time. Only invasive perennial grass cover responded to the revegetation treatment with cover much higher in controls compared with revegetated plots (25.7% vs. 7.7%); this was likely a response to a preplanting herbicide treatment. All categories of species diversity except invasive species diversity increased over time. Only 4% of Russian-olive stumps resprouted in the first year of removal, less than 1% resprouted 2 yr after removal. There was no Russian-olive emergence from seed in the removal year, and seed emergence varied exponentially among following years. Seeded native species did not have trouble establishing once adequate spring moisture occurred in the second growing season after Russian-olive removal, indicating that removal did not present substantial obstacles to successful revegetation. Follow-up control of Russian-olive is critical after initial treatment.

Open-pit mining has affected landscapes and ecosystem balances immensely. The effects are including altered soil surface, decreased soil productivity, soil compaction, erosion and sedimentation, declined biodiversity, as well as deteriorated hydrological, hydrogeological, and atmospheric function of the surrounding area. Reclamation is one of the environmental restoration efforts that could be taken to improve these conditions. Physical and chemical properties of soil are the indicators of soil damage level as well as the success indicator of the reclamation program. This study aims to analyze the changes in post-mining soil characteristics after 5 years and 10 years of revegetation. The sample was selected by the purposive sampling method based on the age of plants and the vegetation density. The physical properties of post-coal soil after 5 years of revegetation are characterized by high soil acidity, low in organic matter (OM)/soil organic carbon (SOC), very low total N (nitrogen), moderate P availability, extremely high K2O, and moderate CEC. Whilst, the post-coal mining soil after 10 years of revegetation is found to be acidic (low pH), with moderate SOC, low total N, low P, very high K2O, and moderate CEC. Heavy metal (Fe, Mn, Al) contents in ex-coal mining reclamation area after 5 years and 10 years revegetation found to be in the high category.

Deforestation and forest degradation are one of the most crucial issues in the forestry sector. The impact of deforestation and forest degradation due to the opening of forest areas for mining activities that causes damage to sustainable forest ecology. This condition requires companies as miners to carry out revegetation activities in post-mining areas to restore forest existence. PT. Vale of Indonesia (PTVI) is a nickel mining company located in Sorowako, South Sulawesi Province, which has carried out revegetation activities and is considered quite successful. This assessment has not included biomass as an indicator of forest productivity.

Abstract Peatland plays an important role as the storage of carbon stocks both in the soil layer and biomass. The value of carbon stocks in peatlands is strongly influenced by the peatland’s quality and potential to produce carbon emissions if the natural conditions are disturbed. Revegetation can improve the quality and land cover compared to natural succession. The success of revegetation can be seen from the survival rate and growth performance of planted species. The purpose of this preliminary study was to see the survival rate and growth of four species of revegetation plants in the burnt peatland area located in Pedamaran, Ogan Komering Ilir, South Sumatra in 2017 and 2021. This study was carried out using quantitative descriptive methods. Results show that the growth performance of four endemic revegetation species was different, reflected by the diameter of breast height (dbh), height, and survival rate. Based on data, pulai (Alstonia pneumatophore) show the best growth performance compared to tembesu (Fragraea fragrans), jelutung (Dyera polyphylla), and balangeran (Shorea balangeran). Pulai showed the highest survival rate (98.61%), with an average dbh growth of 8.31 mm and 75.60 cm in height. Furthermore, all data obtained in this study can be used as basic data for revegetation development to increase growth and survival rate, enhance carbon stocks, and other efforts in climate change mitigation and adaptation.

PT Timah Tbk is a mining industry company which produces the tin metal. A mining former area which is chosen as the research location is Lahan Air Jelitik 3. This research aims to analyze the success of Lahan Air Jelitik 3’s reclamation based on Matrik 16 and Matrik 17 of Keputusan Menteri Energi Sumber Daya Mineral Nomor 1827 Tahun 2018. The research starts with collecting the primary data which consists of 43 and 29 coordinate points of Lahan Air Jelitik 3’s adjustment and revegetation, the length and width of 22 erosion in Blok 1, 24 erosion in Blok 2 and 4 landslide in both blocks, the height and diameter of 35 primary plants and the length of 5 cover crops. Those primary data and secondary data are processed by calculating the broad realization of Lahan Air Jelitik 3’s adjustment and revegetation, the amount of plants, the average of plant’s height and diameter, the stability of area and valuating the success of adjustment area, the success of revegetation, the success of last completion based on Matrik 16, also calculating the success reclamation value based on Matrik 17. The result of data processing shows the success value of adjustment and hoard area is 0.5, top soil’s spreading is 0.91, erosion and sedimentation’s control is 0, cover crop’s revegetation is 0.86, fast growing plant’s revegetation is 0.1765, local plant’s revegetation is 0.726, acid mine drainage’s management is 0, plant’s closure is 0.1059 and plant’s maintenance is 0.333. The reclamation’s success percentage 50.65% in Lahan Air Jelitik 3 PT Timah Tbk shows that the reclamation in that area is not good enough and the area needs improvement especially in plant’s maintenance, erosion and sedimentation’s control and acid mine drainage’s management.

IInformation on land cover change is very important for various purposes, including the monitoring of changes for environmental sustainability. The objective of this study is to create a monitoring model of land cover change for the indication of devegetation and revegetation usingdata fromSentinel-2 from 2017 to 2018 of the Brantas watershed.This is one of the priority watersheds in Indonesia, so it is necessary to observe changes in its environment, including land cover change. Such change can be detected using remote sensing data. The method used is a hybrid between Normalized Difference Vegetation Index(NDVI) and Normalized Burn Ratio (NBR) which aims to detect land changes with a focus on devegetationand revegetation by determining the threshold value for vegetation index (ΔNDVI) and open land index (ΔNBR).The study found that the best thresholds to detect revegetation were ΔNDVI > 0.0309 and ΔNBR < 0.0176 and to detect devegetation ΔNDVI < -0.0206 and ΔNBR > 0.0314.It is concluded that Sentinel-2 data can be used to monitor land changes indicating devegetation and revegetation with established NDVI and NBR threshold conditions.

Revegetation effectiveness requires long-term monitoring. We analysed 50 road slopes 5–8 years and 22–25 years after revegetation. Plant cover and diversity increased over time, with differences between slope types; herbaceous cover increased greatly between revegetation works and 2002 and was similar in 2002 and 2019, while woody cover decreased from revegetation to 2002 but increased greatly between 2002 and 2019. Plant colonisation was more intense on embankments, but could also be achieved on roadcuts (2.4 points on average over a maximum of 5). The presence of sown species decreased over time, but the presence of planted species remained stable. Hydroseeding had poor results in terms of the resulting plant cover, but nevertheless succeeded in slowing erosion at least sufficiently to allow early plant establishment and thus the start of colonisation. The similarity between surrounding vegetation and the slopes was greater in roadcuts. Roads are a gateway for invasive plants. Native species can improve the results, but many are missing from the market. Slopes’ plant cover changed over time; long-term studies are required.

The flood season is the main period for runoff and sediment yield, and understanding the variations of runoff and sediment of flood events is of great significance for distinguishing the runoff-sediment processes in the Loess Plateau. In this study, we analyzed the variations of runoff and sediment at the flood event scale in the Qiaogou catchment and investigated the influencing factors. The results showed that runoff and sediment of flood events were mainly produced by rainfall with short rainfall duration and heavy rainfall intensity in the study area. Based on the 28 flood events and corresponding precipitation data from the reference period (P-I, 1986–1989) and the revegetation period (P-II, 2001–2009), we analyzed the variations of runoff-sediment processes at the flood event scale in the Qiaogou catchment, a typical catchment of the Loess Plateau. The results showed that the flood variables were lower in the revegetation period than those in the reference period, except for the flood peak discharge time and the flood duration. The sediment transport capacity per unit runoff depth in the revegetation period was weaker than that in the reference period. The hysteresis analysis indicated that the patterns of the hysteretic loop were dominated by the figure-of-eight pattern and the compound pattern, respectively, in the reference period and revegetation period. Compared to the reference period, runoff and sediment-related variables for flood events of counter-clockwise, figure-of-eight, and compound patterns were less in the revegetation period. With similar rainfall conditions, the main reason for the noticeable difference in runoff and sediment of flood events for the two periods was the variations in vegetation cover. The mentioned results indicated that revegetation performed a critical function in the variations of runoff and sediment at the flood event scale. This study revealed the variations of runoff-sediment processes of flood events and their responses to rainfall and revegetation in a typical catchment of the Loess Plateau, which can provide a basis for decision-making on soil erosion management and sustainable development of the ecological environment in the Loess Plateau.

Mining results in infertile soil, acidic pH and lack of nutrients. Reclamation activities are one way to restore the benefits of land to be better and more productive in solving this problem. Assessment of reclamation success has been carried out on 8 (eight) IUPs, one of which is PT. Amanah Anugerah Adi Mulia (PT. A3M) in Tanah Laut Regency, South Kalimantan Province. Status PT. A3M has entered the post-mining stage and has rehabilitated mining-affected areas through reclamation and revegetation on the inpit dump land which is divided into three areas, namely the AR-05 area of 3.26 ha of the 2011 Planting Year, the AR-07 area of 3.61 ha of the 2014 Planting Year and the AR-07 area of 3.27 ha of the 2017 Planting Year. Therefore, the purpose of this study is to analyze the status of revegetation success related to the growth and health of revegetated plants in PT. Amanah Anugerah Adi Mulia and identified the factors causing the non-success of revegetation related to the characteristics of post-mining revegetation land. The results of the revegetation analysis regarding the percentage of plant growth and health: the percentage of growth was 96% (2011), 100% (2014) and 100% (2017), with a success value of > 90% (successful category) and a percentage of plant health of 91.14% (2011), 99.2% (2014) and 89% (2017), with a plant health value of > 89% categorized as healthy (normal height, fresh leaves and not yellow).
