Special Issue Information

Dear Colleagues,

Natural disturbances (such as wildfires, storms, and pests) and human-induced disturbances (such as logging, oil and gas extraction, agriculture and other land-use conversions, and pollution) are generally seen as destructive to forest ecosystems, but they can also reset ecological succession, triggering processes that promote recovery and biodiversity. Effective forest restoration must therefore account for the type, frequency, and intensity of disturbances. Restoration spans a continuum from passive approaches—such as removing ongoing stressors and allowing natural regeneration—to active interventions, including planting, enrichment, invasive species control, and soil or hydrological rehabilitation. Managed disturbances, such as controlled burns or selective thinning, can mimic natural processes and guide successional trajectories. In many contexts, hybrid strategies that combine protection with targeted active measures are used to support natural regeneration, improve restoration outcomes, and reduce uncertainty. In practice, a hybrid approach is often used to improve the success rate of forest restoration. In addition, functional restoration promotes recovery of ecosystem processes and dynamics, often benefitting targeted species of interest (e.g., threatened or endangered), as opposed to ecological restoration, which prioritizes the recovery of an ecosystem to its original state.

This Special Issue aims to synthesize recent advances in research on forest disturbance, management, and restoration worldwide, and to provide practical guidance for future restoration efforts, including those that support natural regeneration. We welcome studies based on field observations and experimental designs, as well as review articles. Research articles can focus on post-disturbance forest regeneration dynamics and management interventions, exploring stand-scale forest management practices and their impacts on restoration parameters such as vegetation composition, stand structure, tree growth, or wildlife populations or uses. Articles can also address fundamental questions, such as effects on water uptake or regeneration physiology. We also welcome applied research, such as how restoration or regeneration measures affect economic benefits and timber quality.

Natural forest regeneration offers economic, ecological, and environmental advantages over artificial regeneration; however, its application is often constrained by uncertainties in stand development and management outcomes. Pre-commercial thinning (PCT), a key assisted natural regeneration practice, is widely used to regulate stand density and improve early stand development. Nevertheless, empirical evidence remains limited regarding how post-thinning residual density influences both tree growth and operational performance in high-density naturally regenerated Pinus densiflora stands. This study evaluated three residual density treatments (RD2000, RD3000, and RD5000) following PCT in naturally regenerated pine stands with an initial density of approximately 30,000 stems ha−1. Diameter at breast height, tree height, and crown area were monitored annually over three years, while thinning productivity and operational costs were quantified during treatment implementation. Residual density significantly affected both biological and operational outcomes. The intermediate residual density (RD3000) showed the most consistent growth responses, whereas the lowest residual density (RD2000) resulted in suppressed growth. The highest residual density (RD5000) achieved the highest productivity and lowest operational costs despite moderate growth performance. These results indicate a trade-off between growth performance and operational efficiency and suggest that an intermediate residual density may provide a balanced strategy for managing naturally regenerated pine stands.

Seismic lines are among the most widespread anthropogenic disturbances in Alberta’s boreal peatlands, where repeated petroleum-exploration surveys can alter surface morphology, hydrology, and recovery potential. Although low-impact seismic (LIS) techniques are designed to minimize ground disturbance, the long-term consequences of re-using existing lines remain poorly understood. This study used remotely piloted aircraft system (RPAS)-based LiDAR and optical imagery to examine how peatland microtopography and hydrology evolve following repeated seismic surveys. We quantified four attributes—ground depression, hummock cover, depth to water, and surface water cover—across new seismic lines (cut in 2021), old seismic lines (cut in 1996), and re-disturbance (cut in 1996, re-cut in 2021) LIS lines, as well as adjacent undisturbed peatland, in a boreal fen of northern Alberta. New disturbances were depressed by approximately 10 cm relative to the surrounding peatland and exhibited reduced microtopographic variability. Hummock cover decreased from 21% in the matrix to 6% on new disturbances. Old disturbances showed greater heterogeneity than new disturbances, with hummock cover partially recovering to 14% and surface water increasing from 7% to 27%, reflecting greater spatial heterogeneity in surface conditions. Re-disturbances exhibited microtopographic conditions similar to or more degraded than old disturbances, with hummock cover reduced to 2% and persistently high surface water cover (27%). These patterns suggest that repeated seismic surveys may limit recovery and maintain altered hydrological and microtopographic conditions. Within the context of this case study, even narrow LIS corridors were associated with persistent alterations when re-used, highlighting the importance of considering re-use effects when developing management strategies for peatland ecosystems. RPAS data provide an effective means to quantify these fine-scale changes and inform peatland restoration and seismic line management. Full article
