Comparing Random K-Fold and Spatial Block Cross-Validation for Predicting Post-Fire Vegetation Recovery

Spatial autocorrelation (SAC) can make random cross-validation optimistic for ecological and remote-sensing data, so spatial block cross-validation (SBCV) is widely recommended. How much SBCV changes model assessment depends on how far SAC extends relative to training–test separa...

Season-dependent phenological responses and implications for co-occurring plants and butterflies under climate anomalies and extreme weather events

Abstract Despite extensive work on climate-driven phenological shifts, research has focused primarily on early-season events, single metrics and gradual shifts in mean climate, limiting insights into phenological responses across the full annual cycle. Using a 17-year dataset (20...

LiDAR-Based Thinning Simulation for Changes in Competition Index and Predicted Growth in a Pinus koraiensis Plantation

Thinning effects vary depending on thinning type, intensity, and timing, making it important to compare alternative scenarios before field implementation. We aimed to provide a fundamental basis for selecting appropriate thinning operations by analyzing changes in stand structure...

Monitoring Plant Diversity and Water Resource Recovery Following the Restoration of Degraded Mountain Areas

This study examined long-term changes in floristic composition and hydrological conditions following reforestation in the Yangju Forest Watershed Experimental Catchment, Republic of Korea. The analysis integrated repeated floristic surveys spanning approximately 50 years’ hydrolo...

Characterizing TVOC Increases and Terpene-Derived BVOC Contributions in Wood-Finished Public Facilities

Total volatile organic compounds (TVOCs) are widely used to assess indoor air quality (IAQ). However, because TVOCs combine diverse compounds into a single metric, they cannot distinguish individual emission sources or chemical characteristics. Indoor environments with natural ma...

An Implementation Framework for Integrating Forest Welfare Services Within the Social Services: A Qualitative Study

Population aging is increasing demand for social services, and natural environments are increasingly recognized as health-promoting resources. Korea has institutionalized forest welfare as a national service system delivered through public facilities and a certified professional...

Morphological and Metabolic Changes During Callus-Based Shoot Regeneration in Chamaecyparis obtusa

Chamaecyparis obtusa is a valuable conifer species, prized for its high-quality timber and bioactive essential oils. However, commercial micropropagation is challenging due to its resistance to vegetative propagation. This study aimed to develop an efficient in vitro plant regene...
