This research investigates the effects of land use and land cover (LULC) changes on the ecosystem services of wetlands surrounding Dandi Lake in Oromia, Ethiopia, over 30 years from 1995 to 2025. The study utilizes remote sensing (RS), geographic information systems (GIS), and cloud-based processing through Google Earth Engine (GEE). Landsat satellite images and machine learning techniques, particularly the Random Forest (RF) algorithm, were employed to classify LULC. Historical LULC trends were examined using RF within the GEE platform. To identify the underlying drivers of these changes, a comprehensive approach was adopted, incorporating field observations, focus group discussions, and interviews with local stakeholders. A modified benefit transfer method was applied to assess changes in ecosystem service values (ESVs) resulting from LULC shifts. The findings of the study indicated that population growth, urban expansion, agricultural development, and infrastructure projects are the primary drivers of LULC changes in the Dandi Lake area. Agricultural land has significantly increased, leading to a rise in cropland ESVs from $21.6 million to $24.4 million. However, this growth came at the expense of forests and wetlands, whose ESVs declined markedly from $58.9 million to $23.8 million for forests. Overall, the region experienced a 34 % reduction in total ESVs, decreasing from $123.3 million to $ 81.9 million. These results highlight significant biodiversity losses and reduced ecosystem functionality, underscoring the urgent need for sustainable land use strategies that balance economic development with ecological preservation to maintain environmental integrity and community well-being.

研究了1995 ~ 2025年30年间埃塞俄比亚奥罗米亚丹迪湖周边湿地土地利用和土地覆盖变化对生态系统服务的影响。该研究利用遥感（RS）、地理信息系统（GIS）和基于云的谷歌地球引擎（GEE）处理。Landsat卫星图像和机器学习技术，特别是随机森林（RF）算法，被用于对LULC进行分类。在GEE平台中使用RF检查历史LULC趋势。为了确定这些变化的潜在驱动因素，采用了一种综合方法，包括实地观察、焦点小组讨论和与当地利益相关者的访谈。采用改进的效益转移方法对生态系统服务价值（esv）的变化进行了评价。研究结果表明，人口增长、城市扩张、农业发展和基础设施建设是影响丹地湖区土地利用价值变化的主要因素。农业用地大幅增加，导致农田esv从2160万美元增加到2440万美元。然而，这一增长是以牺牲森林和湿地为代价的，森林的esv从5890万美元显著下降到2380万美元。总体而言，该地区的esv总额减少了34%，从1.233亿美元降至8190万美元。这些结果突出了生物多样性的严重丧失和生态系统功能的降低，强调了迫切需要可持续的土地利用战略，以平衡经济发展与生态保护，以保持环境完整性和社区福祉。

Gullies are series problem globally and accounts for up to 95 % of the sediment eroded from watersheds. Lake Hawassa Watershed (LHW) has been significantly suffering from gully erosion. Despite large number of studies related to gully erosion, the nexus between gully development, formation factors and community perception remains largely unexplored at regional scale. To address this issue, a study was conducted using the Assessment of Gully Erosion Rates through Interviews and Measurements (AGERTIM) method with Geomatica software, Google Earth Pro 10.7.6, ArcMap 10.7.1, and Landsat satellite imagery from Landsat 1.5 to 8. A descriptive and quantitative analysis system was used to conduct the Nexus analysis in terms of proportional and annual rate of change. The gully development timeframe is estimated at 50 years. The results show that an increase in rainfall by 10.12 % leads to an increase in the cultivated area, lineament line density, and top gully width by 20.2 %, 16 %, and 2.24 %, respectively within eight years. Thus, the community faces crop and agricultural land loss due to gully erosion, as 63 % of respondents confirmed. The results also demonstrate a strong nexus between formation factors and gully development, resulting in a long-term erosion rate of 4.01 tons/ha/year and a loss of 142,175.74 m³ of volume within the gully area. It can be concluded from the results that, integrating models with community perceptions plays a key role in investigating the nexus between human-nature interactions and their effects on gully formation and development studies. This research demonstrates the importance of integrating local community perceptions with models to reveal connections in practical decision-making processes and rehabilitation intervention practices for gullies and watersheds.

沟壑是全球性的一系列问题，占流域侵蚀泥沙的95%。哈瓦萨湖流域（LHW）一直受到沟壑侵蚀的严重影响。尽管有大量关于沟壑侵蚀的研究，但在区域尺度上，沟壑发育、形成因素和群落感知之间的关系仍未得到充分探讨。为了解决这一问题，利用Geomatica软件、b谷歌Earth Pro 10.7.6、ArcMap 10.7.1和Landsat 1.5至8的Landsat卫星图像，通过访谈和测量评估沟壑侵蚀率（AGERTIM）方法进行了研究。采用描述性定量分析系统，对比例变化率和年变化率进行Nexus分析。溪谷的开发时间估计为50年。结果表明：8年内，降雨量每增加10.12%，耕地面积、线密度和顶沟宽度分别增加20.2%、16%和2.24%；因此，63%的受访者确认，该社区面临着因沟壑侵蚀而造成的作物和农业用地损失。结果还表明，形成因素与沟壑区发育之间存在密切联系，导致长期侵蚀速率为4.01吨/公顷/年，沟壑区损失了142,175.74 m3的体积。研究结果表明，将模型与社区感知相结合，在研究人与自然相互作用之间的关系及其对沟壑形成和发展的影响方面发挥了关键作用。本研究证明了将当地社区的认知与模型相结合的重要性，以揭示沟渠和流域的实际决策过程和修复干预实践中的联系。

The spatial distribution of species is intricately linked to population dynamics, which influence species site use patterns over time. Environmental factors contribute to these dynamics, which can also be significantly affected by human impacts. Understanding the effects of environmental and human-impact variables on site use dynamics can inform effective conservation strategies. Here, we aimed to assess the relative importance of human-impacts variables (land use types, roads, human settlements) compared to environmental variables (elevation, native forest succession type, distance to water bodies) and their impact on site use dynamics of 15 medium and large-sized terrestrial mammals and four medium and large-sized terrestrial birds in total. We collected data over two years using camera-traps in two state parks of the Atlantic Forest, Brazil, under different degrees of human pressure. We modeled species detection and non-detection data using multi-season occupancy modelling and estimated site use dynamics. Human-impact variables played a greater role in extirpation than environmental variables. Moreover, in the park experiencing a higher degree of human pressures, human-impact variables exerted a greater influence on initial site use and colonization compared to environmental variables. Pastures decreased site use and colonization and increased extirpation, while primary and secondary forests increased site use and colonization of large frugivores. High traffic paved roads decreased site use and colonization and increased extirpation. Human impacts affect dynamics of site use even within restricted protected areas. Therefore, strategies that consider the surrounding landscape and involve collaboration with neighboring communities may improve conservation effectiveness.

物种的空间分布与种群动态有着错综复杂的联系，种群动态影响着物种对地点的长期利用模式。环境因素促成了这些动态，而这些动态也会受到人类影响的显著影响。了解环境和人类影响变量对场地使用动态的影响可以为有效的保护策略提供信息。在此，我们旨在评估人类影响变量（土地利用类型、道路、人类住区）与环境变量（海拔、原始森林演替类型、到水体的距离）的相对重要性，以及它们对15种大中型陆生哺乳动物和4种大中型陆生鸟类的场地利用动态的影响。我们在巴西大西洋森林的两个州立公园，在不同程度的人类压力下，用相机陷阱收集了两年多的数据。我们使用多季节占用模型和估算场地使用动态来模拟物种检测和非检测数据。与环境变量相比，人类影响变量在灭绝中发挥了更大的作用。此外，在人类压力程度较高的公园中，与环境变量相比，人类影响变量对初始场地使用和殖民化的影响更大。牧场减少了立地利用和定植，增加了灭绝，而原生林和次生林增加了大型食果动物的立地利用和定植。高流量的铺砌道路减少了场地的使用和殖民化，增加了灭绝。即使在受限制的保护区内，人类的影响也会影响场地使用的动态。因此，考虑周围景观并与邻近社区合作的策略可能会提高保护效果。

Regional ecological stability is threatened by the rapid land use/cover transition and the acceleration of industrialization. Establishing an ecological security pattern from a dynamic perspective can improve ecosystem service functions and maintain regional ecological stability. Our study focused on the Nansi Lake Basin, devised a comprehensive evaluation framework based on habitat importance, ecosystem function, and landscape connectivity to identify ecological source areas; constructed an ecological resistance surface based on the least cumulative resistance model and adopted the circuit theory to identify ecological corridors; constructed a gray multi-objective optimization-patch generation land use/cover simulation coupled model to optimize the land-use structure in 2035 under three different scenarios, and introduced the key nodes to optimize the ecological security pattern, delineated the regulating subareas, and put forward the planning proposal. The findings revealed that: (1) The urbanization process in the study area, at the cost of sharp reduction in ecological land, was still accelerating; (2) The three scenarios showed different shifting trends in land use/cover, with ecological protection scenario showing a proportion of ecological land had significantly increased, which was expected to better align with policy planning; (3) Ecological source areas and ecological corridors were influenced by the distribution of land use/cover types and were densely distributed in the eastern part of the study area. The findings could serve as corresponding references for establishment of similar regional ecological security patterns and the protection of regional ecological stability.

土地利用/覆被的快速转型和工业化进程的加速威胁着区域生态稳定。从动态角度构建生态安全格局，可以提高生态系统服务功能，维护区域生态稳定。以南四湖流域为研究对象，设计了基于生境重要性、生态系统功能和景观连通性的生态源区综合评价框架；基于最小累积阻力模型构建生态阻力面，并采用回路理论识别生态廊道；构建了三种不同情景下2035年土地利用结构优化的灰色多目标优化-斑块生成土地利用/覆被模拟耦合模型，引入了优化生态安全格局的关键节点，划定了调控分区，提出了规划建议。结果表明：①研究区城市化进程仍在加速，但代价是生态用地急剧减少；②3种情景的土地利用/覆被变化趋势不同，其中生态保护情景的生态用地比例显著增加，与政策规划更加吻合；(3)生态源区和生态廊道受土地利用/覆被类型分布的影响，集中分布在研究区东部。研究结果可为建立类似的区域生态安全格局和保护区域生态稳定提供参考。

Bird species, especially ground-nesting species, are experiencing sharp population declines. Nest predation is one of the main factors limiting the reproductive success of the capercaillie (Tetrao urogallus) in declining populations. This study represents the first trial assessing the use of Conditioned Food Aversion (CFA) as a non-lethal tool to reduce capercaillie nest predation, particularly by red foxes (Vulpes vulpes), within the framework of coexistence conservation strategies. The fungicide Thiram was used as an aversive compound in artificial eggs, and predation rates were compared between a treatment and a control area before and after conditioning (BACI design). In the treatment area, CFA produced a slight reduction in overall nest predation, whereas in the control area a marked increase was observed. At the species level, red fox predation in the treatment area was reduced by a factor of 2.35 compared to controls, demonstrating a significant effect of CFA. No significant effect was observed on predation by martens (Martes martes), suggesting lower conditioning effectiveness in mustelids. Furthermore, the presence of unconditioned juveniles and a slight delay in the post-conditioning phase may have influenced the results. Additionally, nest predation by wild boar (Sus scrofa) and brown bear (Ursus arctos) was detected at low to moderate levels. The study highlights the potential of behavior-based methodologies within coexistence conservation strategies, such as CFA, as viable alternative to lethal control. These tools are not only more socially and ethically accepted but also promote more effective and sustainable conservation of threatened species.

鸟类，尤其是地面筑巢的鸟类，正经历着数量的急剧下降。在种群数量下降的情况下，巢捕食是限制虎斑蝶繁殖成功的主要因素之一。本研究首次评估了在共存保护策略框架内，使用条件食物厌恶（CFA）作为一种非致命工具来减少capercaillie巢穴捕食，特别是红狐（Vulpes Vulpes）。用杀菌剂Thiram作为厌恶性化合物处理人工卵，比较处理区和对照区调节前后的捕食率（BACI设计）。在处理区，CFA略微减少了总体的巢捕食，而在对照区，观察到明显增加。在物种水平上，与对照组相比，处理区红狐的捕食量减少了2.35倍，表明CFA的效果显著。未观察到对鼬鼠捕食的显著影响，表明对鼬鼠的调节效果较低。此外，非条件幼体的存在和后条件阶段的轻微延迟可能影响了结果。此外，野猪（Sus scrofa）和棕熊（Ursus arctos）的巢穴捕食也处于中低水平。该研究强调了基于行为的方法在共存保护策略中的潜力，例如CFA，作为致命控制的可行替代方案。这些工具不仅在社会和道德上更被接受，而且还促进了对受威胁物种的更有效和可持续的保护。

Cariniana legalis Mart. O. Kuntze (Lecythidaceae) is an emergent and endangered rainforest tropical tree and efforts should be made to reintroduce them into the understory of secondary succession forests. We conducted a study aiming to develop allometric models for predictions of roots, leaves, stems and total biomass for young C. legalis plants growing in a wide range of mean daily light integral (DLI), the total daily photosynthetic photon flux density (PPFD). Based on three independent experiments (total N = 206) with a wide range of mean DLI (1 to 43 mol photons m⁻² day⁻¹) we tested two allometric models for prediction of plant biomass from stem diameter measurements. We obtained robust equations for predictions of stem and total plant biomass using a linearized form of a power function. Uncertainties in the predictions of leaves and roots biomass can be explained by the changes in carbon allocation in contrasting light availabilities. The total biomass of young C. legalis plants, with a diameter ranging between 1.6 and 16.5 mm, can be predicted with the equation ln(y) = -1.64636 + 2.25243ln(x), R² = 0.97. If the plants grow in contrasting light availabilities specific strategies are needed to develop allometric models for predictions of the biomass of roots and leaves.

大鲵。黄菖蒲是一种新兴的濒危雨林热带乔木，应努力将其重新引入次生林演替林下。本研究旨在建立在大范围平均日光积分（DLI）、总日光合光子通量密度（PPFD）条件下生长的豆豆幼苗根、叶、茎和总生物量的异速生长模型。基于三个独立的实验（总N = 206），在较宽的平均DLI范围内（1至43 mol光子m−2 day−1），我们测试了两种异速生长模型，用于通过茎直径测量预测植物生物量。我们使用幂函数的线性化形式获得了预测茎和总植物生物量的稳健方程。叶片和根系生物量预测的不确定性可以通过对比光有效性中碳分配的变化来解释。直径在1.6 ~ 16.5 mm范围内的豆豆幼树总生物量可通过ln(y) = -1.64636 + 2.25243ln(x), R2 = 0.97进行预测。如果植物生长在不同的光照条件下，则需要开发异速生长模型来预测根和叶的生物量。

Overabundant ungulate populations in predator-free protected areas always lead to vegetation loss, soil degradation, and disease outbreaks. This study evaluates alternative management strategies for Cabañeros National Park (Spain) following the 2020 hunting ban. Since then, the number of red deer (Cervus elaphus) and wild boar (Sus scrofa) has increased uncontrollably, causing rapid vegetation loss, soil erosion, and the emergence of density-dependent diseases. To conduct this study, a systems dynamics simulation model was developed that integrates ungulate demography, vegetation biomass, and soil quality over a 15-year period (2015–2030). Three scenarios were tested: (i) continued no intervention, (ii) introduction of 10 wolves (Canis lupus signatus) in 2025, and (iii) reinstatement of selective hunting with an annual culling of 15%. Model calibration used monitoring data and literature-based parameter estimates, with sensitivity analyses used to identify key drivers. As a result, ungulate biomass is projected to double by 2030, vegetation cover will decline below ecological thresholds, and soil organic matter will decline irreversibly. Wolf introduction slows population growth but does not allow vegetation recovery within five years. Selective hunting stabilizes ungulate numbers, restores vegetation above the threshold, and halves projected soil loss. Sensitivity analyses highlight ungulate birth rates and hunting rates as the most influential parameters. In conclusion, the model indicates that, under current conditions, regulated hunting is the only proven single-lever policy capable of achieving short-term ecological recovery. The findings provide an evidence-based framework for decision-makers, emphasizing the need for timely intervention to prevent irreversible ecosystem degradation in Mediterranean protected areas.

在没有捕食者的保护区内，数量过多的有蹄类动物总是会导致植被丧失、土壤退化和疾病爆发。本研究评估了2020年狩猎禁令后Cabañeros国家公园（西班牙）的替代管理策略。从那时起，马鹿（Cervus elaphus）和野猪（Sus scrofa）的数量不受控制地增加，导致植被迅速丧失、土壤侵蚀和密度依赖性疾病的出现。为了进行这项研究，开发了一个系统动力学模拟模型，该模型集成了15年（2015-2030年）期间有蹄类人口统计、植被生物量和土壤质量。测试了三种情景：(i)继续不干预，（ii）在2025年引入10只狼（Canis lupus signatus），以及（iii）恢复选择性狩猎，每年淘汰15%。模型校准使用监测数据和基于文献的参数估计，并使用敏感性分析来确定关键驱动因素。因此，预计到2030年有蹄类生物量将翻一番，植被覆盖将下降到生态阈值以下，土壤有机质将不可逆转地减少。狼的引入减缓了种群的增长，但不允许植被在五年内恢复。选择性狩猎稳定了有蹄类动物的数量，使植被恢复到阈值以上，并使预计的土壤损失减半。敏感性分析强调有蹄动物的出生率和狩猎率是最具影响力的参数。综上所述，该模型表明，在当前条件下，有管制的狩猎是唯一被证明能够实现短期生态恢复的单杠杆政策。这些发现为决策者提供了一个基于证据的框架，强调了及时干预以防止地中海保护区生态系统不可逆转退化的必要性。

Ecological restoration is a fundamental response to sudden environmental damage caused by oil spills. In addition to promptly repairing affected ecosystems and resources, restoration efforts should also reflect public environmental preferences to compensate for declines in environmental welfare. Identifying these preferences is essential for improving the social acceptability and implementation effectiveness of oil spill restoration policies. This study takes the 2021 A Symphony tanker collision in the Yellow Sea as a case study. A discrete choice experiment with 515 respondents was conducted to evaluate public preferences for key attributes of ecological restoration, and a latent class model was employed to investigate the sources of preference heterogeneity. Results from the random parameter logit model reveal a strong overall preference for ecological restoration. Among the evaluated attributes, improvements in seawater quality are most preferred, followed by the restoration of marine biological resources and sandy coastlines. Based on the results of the latent class model, respondents can be divided into two types: landscape-oriented and ecology-prioritizing. On average, each household is willing to pay 486.058 CNY (USD 68.250) per year to fully repair the environmental damage caused by the oil spill. The landscape-oriented group places greater emphasis on sandy coastline restoration and is more sensitive to associated costs. The ecology-prioritizing group attaches greater importance to the restoration of seawater quality and marine biological resources and is willing to pay a higher price for this. The latter group is characterized by higher education and income levels, prior experience in environmental volunteering, and relatively high trust in the government. These findings provide policymakers with insights into public preferences regarding oil spill restoration, aiding in the development of effective and sustainable oil spill restoration policies.

生态恢复是应对石油泄漏造成的突发性环境破坏的根本对策。除了迅速修复受影响的生态系统和资源外，恢复工作还应反映公众对环境的偏好，以补偿环境福利的下降。确定这些偏好对于提高溢油恢复政策的社会可接受性和执行效率至关重要。本研究以2021年发生在黄海的A Symphony油轮相撞事故为例进行研究。通过对515名受访者的离散选择实验，评估了公众对生态恢复关键属性的偏好，并采用潜在类别模型探讨了偏好异质性的来源。随机参数logit模型的结果显示，总体上对生态恢复有较强的偏好。在评价属性中，海水质量的改善最受青睐，其次是海洋生物资源的恢复和沙质海岸线的恢复。根据潜在分类模型的结果，被调查者可分为景观导向型和生态导向型两种类型。平均每个家庭每年愿意支付486.058元人民币（68.250美元）来全面修复漏油造成的环境破坏。以景观为导向的群体更重视沙滩海岸线的恢复，对相关成本更敏感。生态优先组更重视海水质量和海洋生物资源的恢复，并愿意为此付出更高的代价。后者的特点是受教育程度和收入水平较高，有环境志愿服务经验，对政府的信任度相对较高。这些发现为政策制定者提供了有关溢油修复的公众偏好的见解，有助于制定有效和可持续的溢油修复政策。

Wildlife Rehabilitation Centres are essential for the care, recovery and potential release of wild animals, while also providing valuable information on the impacts of human activities on biodiversity. In this study, we analyzed 12 years of data (2012 to 2023) from the Wildlife Rehabilitation Centre of Associação Mata Ciliar (CRAS-AMC), located in southeastern Brazil. We investigated the monthly variation in the admission of birds and mammals, identified the main causes of admission, and evaluated how these factors influence the outcomes for the animals, including death, permanent captivity or release. A total of 23,441 bird records representing 329 species and 12,395 mammal records from 73 species were analysed. Among birds, the most common causes of admission were illegal trade and removal requests usually made by members of the public in relation to animals in urban areas, with or without injuries, while mammals were most often admitted due to requested removal from urban areas, dog attacks or vehicle collisions. Mortality was the predominant outcome for both birds and mammals, though outcomes varied according to cause, with higher mortality among animals admitted due to collision with vehicle or trafficking, and higher chances of release among those with minor injuries or mistakenly removed from the wild. These findings demonstrate the importance of long-term data collected by Wildlife Rehabilitation Centres to assess threats to wildlife, guide awareness campaigns and support preventive actions. Additionally, such data can inform improvements in the design and operation of current and future facilities. Strengthening these centres is critical for effective wildlife recovery and biodiversity conservation in Brazil, one of the most biologically diverse countries in the world and increasingly affected by anthropogenic pressures.

野生动物康复中心对于野生动物的照料、恢复和可能的释放至关重要，同时也提供有关人类活动对生物多样性影响的宝贵信息。在这项研究中，我们分析了位于巴西东南部的associa o Mata Ciliar野生动物康复中心（CRAS-AMC） 12年（2012年至2023年）的数据。我们调查了鸟类和哺乳动物入库的月度变化，确定了入库的主要原因，并评估了这些因素如何影响动物的结果，包括死亡、永久圈养或释放。共分析了329个物种的23441个鸟类记录和73个物种的12395个哺乳动物记录。在鸟类中，最常见的入境原因是非法交易，以及通常由公众提出的有关城市地区动物的移走要求，无论是否受伤，而哺乳动物最常见的入境原因是要求从城市地区移走，狗袭击或车辆碰撞。死亡是鸟类和哺乳动物的主要结果，尽管结果因原因而异，由于车辆碰撞或贩运而入院的动物死亡率较高，而轻伤或被错误地从野外带走的动物的释放机会较高。这些发现表明，野生动物康复中心收集的长期数据对于评估野生动物面临的威胁、指导提高认识活动和支持预防行动具有重要意义。此外，这些数据可以为改进当前和未来设施的设计和操作提供信息。加强这些中心对于巴西有效的野生动物恢复和生物多样性保护至关重要，巴西是世界上生物多样性最丰富的国家之一，受到人为压力的影响越来越大。

The mining sector has been responsible for nearly half of Colombia’s exports over the past decade. As a tropical country with high biodiversity, Colombia still has half of its territory covered by forests. We have analyzed the rehabilitation or restoration techniques used in post-mining, gas and petroleum areas in Colombia’s natural region, which is the first systematic review of scientific articles published until 2024 in six academic databases (Scopus, Web of Science, Scielo, ScienceDirect, EBSCO, and DOAJ). The search recorded a total of 84 case studies, with a focus on metallic mining (∼ 61 %), followed by coal mining (∼ 35 %), non-metallic mining (∼ 2 %), and petroleum (∼ 2 %). No study on gas activity were found. Overall, the use of multiple rehabilitation or restoration techniques and ecological indicators is rare in these studies. The most common techniques in studies on metallic mining were natural regeneration (∼ 49 %) and bioremediation (∼ 37 %), whereas in coal mining studies, they were physical intervention (∼ 59 %) and planting of native species (∼ 48 %). Despite the recent boom in petroleum and gold exploitation in the Amazon and Orinoquía regions, studies in these areas are scarce. However, we found coal mining, where active intervention is predominant, appears to exhibit a more accelerated ecological recovery process, although a longer evaluation period is required. Ecosystem components such as soil, water, as well as organisms other than plants, should be included more frequently in assessments. Our findings provide support for evidence-informed decision-making related to improving the recovery of post-mining and petroleum areas in Colombia.

在过去十年中，采矿业占哥伦比亚出口的近一半。作为一个生物多样性很高的热带国家，哥伦比亚仍有一半的领土被森林覆盖。我们分析了哥伦比亚自然区域开采后、天然气和石油区域使用的恢复或恢复技术，这是对六个学术数据库（Scopus、Web of Science、Scielo、ScienceDirect、EBSCO和DOAJ）中发表的科学文章的首次系统综述。此次检索共记录了84个案例研究，其重点是金属开采（~ 61%），其次是煤炭开采（~ 35%）、非金属开采（~ 2%）、石油开采（~ 2%）。没有发现关于气体活性的研究。总体而言，在这些研究中，使用多种修复或恢复技术和生态指标是罕见的。在金属开采研究中最常见的技术是自然再生（~ 49%）和生物修复（~ 37%），而在煤矿开采研究中，它们是物理干预（~ 59%）和种植本地物种（~ 48%）。尽管最近亚马逊和Orinoquía地区的石油和黄金开采蓬勃发展，但对这些地区的研究却很少。然而，我们发现，在积极干预占主导地位的煤矿开采中，尽管需要更长的评估期，但似乎表现出更加速的生态恢复过程。生态系统组成部分，如土壤、水以及植物以外的生物，应更频繁地列入评估。我们的研究结果为改善哥伦比亚采油后采收率的循证决策提供了支持。
