While there is nothing inherently wrong with storing more carbon in forest ecosystems, the scale of what can be achieved through improved forest management is dwarfed by current fossil fuel emissions and may be a distraction from the fundamental cause of climate change. It is important to first recognize that the burning of fossil fuels represents, by far, the single largest source of anthropogenic greenhouse gas emissions. Fossil fuel carbon would not mix with the global atmosphere if humans did not mine it, refine it, and burn it, making fossil fuel carbon a novel and semi-permanent addition to globally cycled carbon. In contrast, carbon stored in forests and soils is a product of photosynthetic capture of carbon and incorporation into live and ultimately detrital biomass. These forms of biogenic carbon represent cycled carbon that is only stored on short-term or potentially centennial timescales making the trade for fossil fuel-based emissions a poor one. Increased carbon storage from ‘improved forest management’ (e.g., increased rotation length or partial harvests) requires that a verifiable net increase in carbon storage is achieved with shifts in forest management strategies. Yet, to date, this verified additionality has proven elusive. Finally, increasing forest carbon storage via conservation or preservation strategies in one region, without reducing global forest product demand, may simply increase net carbon emissions in the parts of the world where a static or increasing product demand is met, otherwise known as “leakage.” Even if the leakage and additionality challenges in forest carbon storage can be met, terrestrial carbon storage can still only be viewed as a tool for temporary drawdown of atmospheric carbon, and thus will only prove effective if it is coupled with significant reductions in fossil fuel emissions, which to date have only been increasing on a global scale. In the absence of significant reductions in fossil fuel emissions, forest carbon storage as a nature-based solution will merely serve as a feel-good action and a distraction from meaningful efforts to reduce fossil based carbon loading of the atmosphere.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"586 ","pages":"Article 122691"},"PeriodicalIF":3.7,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We designed a Before-After Control-Impact experiment in 11 40–80 year old mixed forests on abandoned agricultural land in the boreonemoral zone of Sweden and Norway and performed restoration cutting by the removal of ca 22 % of the total volume timber (mainly spruce <em>Picea abies</em> but also some birch <em>Betula</em> spp) from 1 ha thinned plots. Our results show a significant increase in the total number of individuals and species of insects following the experimental treatment. Species richness of flower-visiting insects and Syrphidae increased significantly as a result of restoration cutting, while abundance increased for all insect groups. The treatment also had a significant positive effect on species richness of vascular plants, including number of flowering species. There was a positive relationship between the increase in plant species richness and the richness and abundance of insects.

We harmonized National Forest Soil Inventory (NFSI) data from Sweden, Denmark, Finland, Norway and Canada to examine soil C stocks up to 53 years following clear-cut harvest using a space-for-time approach. We analyzed forest floor and mineral soil C stocks in coniferous and deciduous/mixed forests.

No C stock changes were detected in the 0–10 cm or 10–20 cm mineral soil layers, while a small increase in 55–65 cm mineral soil was detected in Podzol soils.

However, for forest management it remains unclear whether current CNF strategies sufficiently reduce forests’ predisposition to climate-change-induced shifts in disturbance regimes. To address this increasing complexity, we introduce the integration of a climate-sensitive forest gap model with assessments of predisposition to fire, bark beetle, and windthrow disturbances, as well as BES provision. We conducted simulations for a forest enterprise in the Central Swiss Alps, covering a large elevation gradient, under three climate scenarios (historical, SSP2–4.5, and SSP5–8.5). The simulations additionally considered six management strategies, including CNF variants with different management intensities and climate-adapted approaches. Our results indicate that climate change will dynamically alter disturbance predisposition across elevation gradients. Site-related predisposition to fire and bark beetle infestation generally increased under climate change, while stand-related predisposition to all disturbances varied with climate scenario and elevation. Under moderate warming (SSP2–4.5), stand-related predisposition to fire and windthrow increased across all elevations. In contrast, under severe warming (SSP5–8.5), long-term reductions in stand-related predisposition to fire, bark beetle infestation, and windthrow occurred at lower elevations due to climate-change-induced shifts in forest dynamics, while predisposition increased at higher elevations with improved growing conditions. Our results further show that increasing management intensity generally reduces stand-related disturbance predisposition but focusing purely on disturbance mitigation can also lead to trade-offs, such as reduced BES provision. We conclude that climate-adapted forest management must account for both stand-related and site-related predisposition to prioritize disturbance-prone ‘hotspots’, especially in areas of high BES value. Proactively reducing disturbance predisposition may involve trade-offs regarding BES provision but may be crucial to avoid potential BES losses from severe disturbances. As climate change may alter trade-offs between BES and disturbance mitigation, we underscore the need for decision support systems in long-term forest planning to account for conflicting management objectives.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"586 ","pages":"Article 122690"},"PeriodicalIF":3.7,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mistletoe abundance enhanced crown defoliation at all scales. At continental scale, the percentage of infested trees has been increasing reaching values close to 15 % in 2019. At regional scale, mistletoe infestation was severe in 19 % of sampled trees. At local scale, mistletoe infestation contributed to forest decline through growth loss and decreased cone production. Silver fir stands with more trees heavily infested by mistletoe showed abundant winter fleshy-fruited species such as <em>Sorbus aria</em>. Mistletoe led to lasting (12 years prior to sampling) and irreversible growth reduction (−78 % in site VI, −44 % in site SN) in severely infested trees as compared to lightly infested coexisting trees. The acute defoliation of the upper crown in severely infested trees negatively impacted cone production, but this effect was significant only at local scale.
