Established invasive tree species (EITS) may take over the vacant space potentially preventing the regeneration of the preferred native tree species. This paper aims to investigate how expansion of these invasive non-native tree species can be addressed in a context of climate-smart forest management, considering alternatives to costly and often ineffective EITS control measures.</p><h3 data-test=\"abstract-sub-heading\">Recent findings</h3><p>We found that forest ecologists increasingly recognize that climate-smart forest management, in particular tree species diversification and close-to-nature forest management, can strengthen the resilience of forests against negative impacts by EITS. In the resulting resilient forest ecosystems, a more closed canopy may deprive EITS of their invasive nature, and EITS may contribute to climate change adaptation.</p><h3 data-test=\"abstract-sub-heading\">Summary</h3><p>This review proposes new pathways for forest management transcending the apparent incompatibility between the dominance of EITS and the adaptation capacity of forests and forest management to climate change. Adaptive measures to increase the resilience of forests to climate change may prevent the dominance of EITS. Under such conditions, useful functional traits of these tree species may even contribute to maintenance or enhancement of biodiversity, provisioning of ecosystem services and adaptation to climate change.</p>","PeriodicalId":48653,"journal":{"name":"Current Forestry Reports","volume":null,"pages":null},"PeriodicalIF":9.5,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some forests provide higher quality habitat for these organisms than others. The primary objectives of this article are to 1) review how pollinator communities are influenced by changes in forest structure, composition, and age, 2) explore how these patterns differ between conifer and broadleaf forests, and 3) provide recommendations for managers interested in optimizing forest conditions for pollinating insects.</p><h3 data-test=\"abstract-sub-heading\">Recent Findings</h3><p>Although biodiversity generally increases as forests mature and become more structurally and compositionally complex, patterns exhibited by pollinating insects vary depending on forest type and prevailing disturbance regimes. For example, conifer forests can either sustain pollinator diversity comparable to open habitats or experience reduced pollinator diversity depending on the openness of the canopy. In broadleaf forests, pollinator diversity often increases with age (following the stem exclusion stage) and increasing tree diversity, and diversity in these areas can exceed what is observed in open habitats even under closed-canopy conditions. Such patterns likely reflect the importance of flowering broadleaf trees to pollinators, including many forest-dependent species, and suggest that optimal management practices for conserving pollinators differ between conifer and broadleaf forests.</p><h3 data-test=\"abstract-sub-heading\">Summary</h3><p>We conclude that: 1) the quality of forests to pollinating insects is a function of forest structure and composition as mediated by forest age and disturbance history and 2) best management practices need to be developed separately for conserving pollinators in conifer and broadleaf forests.
