Abstract

The conservation of biodiversity and carbon sequestration in forests has global significance. In this study, we aimed to investigate strategies to enhance biodiversity and forest carbon pools in temperate forests. We analyzed soil sample data from 725 plots (400 m² each) collected from the National Forest Inventory of South Korea, categorizing them into three forest stand types: conifer, broadleaved, and mixed stands. Abiotic drivers (topographic and climatic factors, and soil properties), biotic drivers (taxonomic and functional trait diversity, functional trait identity, and stand structural diversity), and forest development stage-related factor (stand age) served as independent variables. We applied a multimodel averaging approach and piecewise structural equation modeling to identify the main drivers and linkages controlling forest carbon pools, including tree biomass, coarse woody debris, and soil organic carbon (SOC) for each stand type. Our findings revealed that stand age–driven tree size variation (i.e., standard deviation of diameter at breast height) influenced each forest carbon pool across all stand types, with different biotic drivers affecting the linkages among carbon pools depending on forest type. Additionally, environmental conditions, especially soil chemical properties, were the main drivers controlling SOC among forest carbon pools. In this study, we suggest that different forest management plans should be implemented to enhance the carbon sequestration capacity and biodiversity of each forest stand type.

期刊介绍： Forest Ecology and Management publishes scientific articles linking forest ecology with forest management, focusing on the application of biological, ecological and social knowledge to the management and conservation of plantations and natural forests. The scope of the journal includes all forest ecosystems of the world. A peer-review process ensures the quality and international interest of the manuscripts accepted for publication. The journal encourages communication between scientists in disparate fields who share a common interest in ecology and forest management, bridging the gap between research workers and forest managers. We encourage submission of papers that will have the strongest interest and value to the Journal''s international readership. Some key features of papers with strong interest include: 1. Clear connections between the ecology and management of forests; 2. Novel ideas or approaches to important challenges in forest ecology and management; 3. Studies that address a population of interest beyond the scale of single research sites, Three key points in the design of forest experiments, Forest Ecology and Management 255 (2008) 2022-2023); 4. Review Articles on timely, important topics. Authors are welcome to contact one of the editors to discuss the suitability of a potential review manuscript. The Journal encourages proposals for special issues examining important areas of forest ecology and management. Potential guest editors should contact any of the Editors to begin discussions about topics, potential papers, and other details.
