Incorporating site suitability and carbon sequestration of tree species into China’s climate-adaptive forestation

Science Bulletin, Journal Year: 2025, Volume and Issue: unknown

Published: March 1, 2025

Strategic selection and precise matching of climate-resilient tree species are crucial for maximizing the mitigation adaptation potential Climate-Smart Forestry. However, current forestation plans often overlook species-specific environmental shifts, leading to suboptimal long-term carbon sequestration. Here we developed a climate-adaptive optimization framework guide planting in China, based on projected habitat suitability range shifts under future climate scenarios. Utilizing over 200,000 records from China's National Forest Inventory (1999-2018), quantified declines 12.1%-42.9% currently dominant plantation by 2060 due change. By optimizing species-site strategically harvesting timber at peak uptake, identified 43.2 million hectares suitable between 2025 2060, enabling approximately 46 billion climate-adapted trees with total sequestration 3822.6 Tg carbon-a 28.7% increase compared unmanaged Our study highlights importance adaptive strategies enhance conditions, providing technical guidance forest management support net-zero commitment.

Soil Organic Carbon Increases With Decreasing Microbial Carbon Use Efficiency During Vegetation Restoration

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(12)

Published: Dec. 1, 2024

ABSTRACT Microbial carbon (C) use efficiency (CUE) describes the proportion of organic C used by microorganisms for anabolic processes, which increases with soil (SOC) content on a global scale. However, it is unclear whether similar relationship exists during natural vegetation restoration in terrestrial ecosystems. Here, we investigated patterns CUE along 160‐year chronosequence (from farmland to climax forest) estimated stoichiometric modeling; additionally, examined between and SOC combined these results meta‐analysis. The combination indicated that decreased from 0.35 0.28. Surprisingly, increased decreasing because forest soils have low pH values high microbial phosphorus limitations compared early ecosystems, implying forests may not sequester as much expected. shift was most important predictor climate, plant, factors. changes were directly induced pH‐induced community. Alkaline acidification tended decrease CUE. This first large‐scale estimate highlights need strengthen sink management mature sustain their sequestration potential.

Variation in local communities of insect pollinators in different land-use types in Northeastern Thailand

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Variations in land-use types reflect different levels of human activity, which can affect local biodiversity. We examined how influenced the composition insect communities. analyzed spatial and temporal patterns four key pollinating groups: Coleoptera, Diptera, Hymenoptera, Lepidoptera (CDHL) across types: agricultural land, abandoned urban area, a forest patch Khon Kaen, northeastern Thailand, over three seasons. The supported highest diversity species richness CDHL, whereas land abundance. Species turnover was more pronounced between than seasons area had seasonal variation. were most abundant group both space time, contributing to 76% all CDHL records. Diptera comprised 15.75%, 5.74% 2.52% records, respectively. Apis florea bee, but A. cerana dorsata showed considerably low numbers. Diversity abundance ground flowers significantly correlated with Air temperature, humidity, trees appeared overall distribution at family level CDHL. Implications for conservation data provide comprehensive understanding dynamics pollinator communities human-dominated landscapes. results suggest negative effect urbanization on highlight importance conserving natural human-modified green mosaics that maintain ecological connectivity landscape matrices.

Systematic conservation planning for nature recovery

BioScience, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

Abstract Nature conservation is increasingly focused on recovering depleted populations and ecosystems. The United Nations General Assembly has proclaimed 2021–2030 the UN Decade Ecosystem Restoration, global commitments to ecosystem restoration in response biodiversity, climate, sustainable development targets are now considerable, with over 100 nations committed halting reversing forest loss land degradation by 2030. impacts of these resources nature recovery will depend how actions identified implemented. Systematic planning historically been used prioritize areas for protection but shown great potential guide that underpinned principles spatial planning. In present article, we advocate systematic target show well-established frameworks can be developed appropriately, particularly integrating models forecasting ecological, social, economic conditions prioritization methods designed resources.

Global trends in biodiversity with tree plantation age

Global Ecology and Conservation, Journal Year: 2023, Volume and Issue: 48, P. e02751 - e02751

Published: Nov. 29, 2023

Tree plantations are expanding globally to satisfy demands for wood, food, energy, oil and other ecosystem services, often replacing primary vegetation. Plantations generally less biodiverse than vegetation, yet the effects of plantation age on biodiversity not well understood. More accurate estimations within over time could improve predictions ecological tree planting, guiding more sustainable land use management decisions. Here, we assess abundance number species invertebrates, birds, plants, mammals, amphibians, reptiles lichens, compositional similarity minimally-used We find that usually support fewer both vegetation mature secondary individuals, some novel (i.e. also found in vegetation). that, a global scale, has positive richness, However, geographic realm, biome, intensity type influence trends. include case study palm, showing richness increases with palm age.

Balancing climate goals and biodiversity protection: legal implications of the 30x30 target for land-based carbon removal

Frontiers in Climate, Journal Year: 2023, Volume and Issue: 5

Published: Dec. 20, 2023

This article examines the legal conflicts between land-based carbon dioxide removal (CDR) strategies and establishment of protected areas through lens international environmental law. We argue that 2022 Global Biodiversity Framework's “30x30” target—which aims to protect 30% global terrestrial marine by 2030—constitutes a “subsequent agreement” under law thus clarifies scope content obligation establish Article 8 Convention on Biological Diversity (CBD). Since states have pledged 120 million square kilometers for CDR, these commitments potentially conflict with target, especially if cropland food production is be maintained. Consequently, some CDR may directly or indirectly impede achievement which could deemed inconsistent However, as all operates in continuum, this does not imply should categorically ruled out. Rather, focus emission reductions implementing options provide most co-benefits climate mitigation biodiversity protection efforts.
