Key growth parameters—including biomass, maximum height, number of leaves, and culms—were recorded, along with tissue nutrient content (C, N, P, K, Mg, Ca, S, B, Cu, Fe, Mn, Zn) and analyzed using inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). <em>Juncus effusus</em> in single-species cultures produced a higher average aboveground biomass and culm production than in paired cultures, where this species increased its own Ca, Mg, Cu, and Mn uptake.

We recorded weather data (precipitation and air temperature), water temperature inside the woodchip filter and flow rates at 15-min time intervals. Additionally, water samples were taken from the influent and effluent several times a week and analyzed for nitrate, dissolved reactive phosphorus (DRP), total phosphorus (TP) and total organic carbon concentration (TOC). After seven monitoring seasons (November to April), the main results can be summarized as follows. Nitrate removal efficiency and nitrate removal rate were on average 59 % and 5.5 g N m⁻³ d⁻¹, respectively, indicating that microbial denitrification takes place in winter at water temperatures &lt;8 °C. After initial flushing, the bioreactor acted also as a sink for phosphorus (ca. 61 % TP load reduction). However, as a negative side effect, the bioreactor released organic carbon and the TOC load increased by ca. 59 % at the outlet as compared to the inflow. The results indicate further that the hydraulic retention time is crucial for an optimal management of denitrifying bioreactors. Increasing the hydraulic retention time leads to greater nitrate removal efficiencies and vice versa. In contrast, water temperature fluctuations throughout the drainage season did not influence the performance of the bioreactor.

In this study, we use historical data to evaluate how the channelization of the river and its restoration 40 years later affected the aquatic biodiversity. Generally, and as expected, we observed a significant reduction in the taxon richness of aquatic plants and EPT taxa (Ephemeroptera, Plecoptera, and Trichoptera) in response to the channelization, especially taxa associated with backwaters. As hoped, the restoration mediated an increase in taxon richness for both aquatic plants and EPT taxa. This positive response took place immediately after the restoration (1 year) and persisted throughout the study period (10 years). However, taxon richness did not reach the pre-channelization levels. Especially, we observed that the recovery of backwater-associated taxa was limited. The main reason for this is likely that only 5.8 % of the original backwater area was recreated and, additionally, that natural regeneration of these areas relies on natural hydromorphological processes that might take several decades. Furthermore, the possibility of several taxa to recolonize from other and distant areas is poor, reflecting today's rarity of backwater habitats in Danish rivers. Full recovery of the river's former biodiversity might therefore take decades or more without implementing active measures.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"218 ","pages":"Article 107664"},"PeriodicalIF":3.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, our understanding of how various past land uses affect natural restoration remains incomplete, particularly across restoration types. This study conducted a meta-analysis of 2112 experimental datasets from 212 published studies in China to examine the effects of five past land uses (farming, mining, burning, logging, and grazing) on vegetation and soil properties during natural restoration. The analysis also explored the influence of environmental factors and restoration duration on these responses. The results revealed significant differences in vegetation and soil properties depending on the past land use. Among land uses, natural restoration was the least effective after mining (vegetation properties: −164.33 %, soil properties: −153.44 %) and the most effective after logging (vegetation properties: 63.08 %, soil properties: −27.86 %). Furthermore, as natural succession progressed to different restoration types, vegetation and soil properties responded differently to past land uses. For example, when restoration led to grasslands, logging yielded the best outcomes, with vegetation coverage, diversity, soil moisture (SM), and total phosphorus (TP) exceeding reference levels by 39.06 %, 39.25 %, 32.08 %, and 13.70 %, respectively. When restored to shrubland, burning produced better outcomes, with plant diversity, bulk density (BD), pH, and TP exceeding reference levels by 23.16 %, 12.69 %, 2.85 %, and 7.15 %, respectively. For forest restoration, the vegetation and soil properties following farming, burning, and logging were similar to the reference levels, and the evenness index (17.15 %) significantly improved after logging (<em>p</em> &lt; 0.05). Climate factors, specifically mean annual precipitation and temperature, were secondary only to past land use in influencing vegetation and soil properties during natural restoration. Although most vegetation and soil properties performed better in areas with high temperatures and precipitation, those following mining showed no significant spatial variations. The restoration outcomes were generally favorable for gentle slopes and moderately textured soils. However, when the slope gradient exceeded 25°, plant diversity improved by 18.33 % and 17.57 % after burning and logging, respectively. After burning and logging, vegetation and soil properties can reach or surpass pre-disturbance levels within a few years (&lt; 5 years) and remain stable over the long term (&gt; 30 years). Overall, natural restoration is most suitable for land recovery after logging and burning and is recommended for farming and grazing under favorable hydrothermal conditions and extended durations.

Recently, nature-based solutions have gained increasing interest, particularly those focusing on forest restoration for long-term carbon sequestration and additional societal benefits for human well-being. Thus, forest restoration, especially with native species, offers a viable pathway to address environmental and social challenges while supporting local communities. However, both technical and scientific knowledge about many native species' performance in large-scale plantations, which could serve the current and future needs of central African countries, is currently lacking. To address these knowledge gaps, we established an experimental plantation in Yangambi, Democratic Republic of the Congo, to evaluate the potential of native tree species in comparison with the fast-growing exotic species <em>Acacia auriculiformis,</em> which is often planted in monoculture at a large-scale in the central Congo Basin. From 37 promising native species initially selected, the seeds of 19 were successfully harvested from the natural forest. Among these, 16 species yielded sufficient seedlings in the nursery and were planted in the field. After five years, five native species (<em>Pachyelasma tessmannii, Piptadeniastrum africanum, Irvingia smithii, Ongokea gore,</em> and <em>Canarium schweinfurthii</em>) demonstrated growth, survival, and carbon sequestration performance comparable to <em>Acacia auriculiformis</em>. This illustrates that local tree species are promising alternatives for exotic species. Nevertheless, further research is necessary to optimize the large-scale production of native seedlings, including improving seed conservation and nursery techniques. Drawing on the ongoing forest restoration initiatives in Yangambi, we emphasize the importance of integrating local knowledge and actively involving local communities to ensure the successful implementation and long-term sustainability of tree-planting efforts, benefiting both nature and human well-being.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"217 ","pages":"Article 107662"},"PeriodicalIF":3.9,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
