Summary: This study used non-metric multidimensional scaling to investigate the impact of tundra microsite conditions and changes in plant community on the requirements of black spruce at different life stages. The results showed that the microsite associations of black spruce change throughout its life cycle, primarily driven by changes in plant community and soil moisture. These associations limit the establishment and reproduction of black spruce to a subset of microsites available within the heterogeneous landscape.

Summary: Revegetation is crucial for achieving the goals of the UN Decade on Ecosystem Restoration, with the success of selecting direct seeding or planting depending on the situation and plant species. However, there is currently no clear guidance on when to prefer one method over the other.

Summary: The timing of xylem formation in black spruce is determined by environmental conditions, with spring temperatures playing a crucial role in initiating cambial activity. However, the end of xylem phenology appears to be less influenced by temperature. Under warming conditions, the onset of xylogenesis is expected to advance, potentially leading to an extended growing season and increased cell production.

Summary: In this study, the impact of different mechanical site-preparation tools on the mycorrhizal fungal communities associated with natural-regeneration Scots pine seedlings after clearcutting was investigated. The results showed that any method of mechanical site preparation reduced the level of root mycorrhization and the biodiversity of mycorrhizal fungi, while the non-mechanical site preparation control had the highest diversity of mycorrhizal fungi.

Summary: Roughly 2 billion hectares of degraded land worldwide require ecological restoration. The choice between direct seeding and planting nursery-grown seedlings in the revegetation process can affect plant survival, performance, and economic implications for restoration. The systematic map database identifies research gaps and enables managers to find relevant literature on the appropriateness of seeding versus planting.

Summary: Our study aimed to assess the impacts of varying forest gap sizes on the density, growth, and spatial patterns of seedlings and saplings in spruce forests. The findings indicated that forest gap size did not significantly influence the density of seedlings or the ground diameter growth of saplings, but it did significantly influence the height growth of saplings. As the gap size increased, natural regeneration shifted from the edge areas to the gap centers. Large forest gaps exhibited the highest percentages of random distribution patterns.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.

Summary: This study compares the phenology of black spruce using PhenoCam and MODIS data, and finds that the EVI index is more suitable for evaluating the phenology of evergreen species in the northern boreal region.

Summary: The study assessed the effects of seed source and forest cover on the germination and survival of Cryptocarya alba established through direct seeding. Different forest cover types were identified within the natural park, with the dense forest cover showing the highest germination and survival rates. It is recommended to use local seeds on dense forest cover for the direct seeding of this species in Mediterranean-type climate zones prone to droughts.

Summary: This research evaluates a pioneering restoration program in the southern Brazilian Atlantic Forest and examines the interactions between ecological restoration and other conservation strategies. The study finds that the proportion of old-growth forests positively influences species diversity, biomass, and functional diversity in restoration areas. The choice of restoration strategy also affects forest structure and species composition, with reforestation showing more positive outcomes compared to natural regeneration.

Summary: The study found that in the third year, the soil respiration rates of the young forest established through assisted natural regeneration were similar to those of the secondary forest, but significantly higher than those of the young plantation. Soil respiration rates in all forests mostly increased exponentially with rising soil temperature, but lacked significant relationships with soil moisture.

Summary: The study evaluated the recovery of woody vegetation from 23 restored forests located on the southern edge of the Brazilian Amazon. After 12 years, the restored forests exhibited lower species richness, alpha diversity, aboveground biomass, basal area, and a dissimilar floristic composition compared to adjacent primary forests. Recovery rates for aboveground biomass, basal area, alpha diversity, and species richness in primary forests were higher than in restored forests, indicating ongoing recovery. The presence of non-seeded species in restored forests suggests that direct seeding fosters spontaneous regeneration from the regional species pool.

Summary: In this study, an efficient regeneration system for Picea mongolica was developed, with optimal plant growth regulators and donor trees identified for somatic embryo generation. The positive developmental window for somatic embryo initiation was determined, providing key insights for plantlet regeneration. These results may contribute to the establishment of a reliable protocol for vegetative propagation and urban greening applications in arid areas.

Summary: Sufficient soil scarification is important for the regeneration of Scots pine. Even light site preparation methods can provide satisfactory regeneration results. Reindeer grazing limits optimal regeneration. Further research is needed on the use of seed pellets, but they may have potential.

Summary: The study on the impacts of site preparation, seeding, and livestock grazing on plant communities after the construction of a buried natural gas pipeline corridor in the southwestern United States found that site preparation and topsoil treatment had ongoing positive effects on richness and cover, while seeding only increased cover and richness in the first year of monitoring. Grazing and trampling effects were not significant, and the effects of livestock may have been confounded with effects of small mammals due to the exclosure configuration. Thus, site preparation, topsoil treatment, and linear configuration of the disturbance corridor allowed for high levels of natural recruitment.

Summary: This study investigated public attitudes towards multi-storey wood buildings in seven European countries and found that the level of knowledge about wood buildings was lower in countries where brick, stone, and concrete were commonly used in construction, such as the United Kingdom, Germany, and Denmark. Finland and Sweden had the most positive attitudes towards wood buildings. The study also identified factors such as fire vulnerability, material solidity, indoor environment, and moisture vulnerability that influenced people's perception of wood buildings as a nice place to live.
