“…If the forest physiognomy of the same age class is greater than the number of potential cutting areas within the size of the potential cutting area determined for each scenario, the forest growing stock volume is cut in order of highest to lowest. Crown thinning was implemented twice a year [ 46 – 48 ]. where is the potential cutting area for year is the stand, is the year, is the stand age for the tree species, is the legal final cutting age of tree species , and MA is the area where forest management is possible.…”

Background Forests are atmospheric carbon sinks, whose natural growth can contribute to climate change mitigation. However, they are also affected by climate change and various other phenomena, for example, the low growth of coniferous forests currently reported globally, including in the Republic of Korea. In response to the implementation of the Paris Agreement, the Korean government has proposed 2030 greenhouse gas roadmap to achieve a Nationally Determined Contribution (NDC), and the forest sector set a sequestration target of 26 million tons by 2030. In this study, the Korean forest growth model (KO-G-Dynamic model) was used to analyze various climate change and forest management scenarios and their capacity to address the NDC targets. A 2050 climate change adaptation strategy is suggested based on forest growth and CO2 sequestration. Results Forest growth was predicted to gradually decline, and CO2 sequestration was predicted to reach 23 million tons per year in 2050 if current climate and conditions are maintained. According to the model, sequestrations of 33 million tCO2 year−1 in 2030 and 27 million tCO2 year−1 in 2050 can be achieved if ideal forest management is implemented. It was also estimated that the current forest management budget of 317 billion KRW (264 million USD) should be twice as large at 722 billion KRW (602 million USD) in the 2030s and 618 billion KRW (516 million USD) in the 2050s to achieve NDC targets. Conclusions The growth trend in Korea's forests transitions from young-matured stands to over-mature forests. The presented model-based forest management plans are an appropriate response and can increase the capacity of Korea to achieve its NDC targets. Such a modeling can help the forestry sector develop plans and policies for climate change adaptation.

“…This results in asymmetric competition [80,81], that is, the share of resources used by larger trees is disproportionally larger than those used by smaller trees, resulting in the growth suppression of the latter [35,80]. Thus the increase in growth at tree level is maintained or enhanced by the methods where release occurs in the upper layers and/or favours future trees (from above, Schädelin, free, compensation, crown release or variable density thinnings) [7,20,23,30,31,39,59,60,82,83]. This is especially true if the thinning is carried out before canopy closure and crown recession [47].…”

“…After thinning, the trees increase their growth, frequently 1-3 years after thinning [50,82] due to the availability of growing space. The growth increase derives in the increase of crown volume (width and length), crown cover [90,97] and foliar mass enhancing photosynthetic capacity, as the lower parts of the crowns receive more light than unthinned stands [98].…”

Thinning is one of the primordial silvicultural practices. It has been analysed by its methods and intensities, associated to the tree selection criteria. Yet, while some methods are of generalised use, others were developed for specific purposes. The goal of this review is to compile the existing information regarding tree selection, thinning methods and intensity as well as their effects on trees and stands. The effects of thinning indicate a reduction of density and a trend towards an increase of growth rates at tree level for a short time after thinning. Biomass and volume show similar or smaller values when compared to unthinned stands. Mortality and growth stagnation, especially in stands with low stability or vigour, can also occur. The modifications in stand structure can enhance its role as an adaptive measure.

La dendroecología es una subdisciplina de la dendrocronología, que se refiere al estudio de los procesos ecológicos en un bosque por medio del análisis de anillos de crecimiento de los árboles de un rodal. Esta subdisciplina es útil para comprender la dinámica de crecimiento en condiciones naturales y de manejo. El objetivo del presente estudio fue hacer una revisión sobre la aplicación de la dendroecología como herramienta en manejo forestal. Se identificaron 78 trabajos que involucraron 118 especies. Los países donde se ha realizado un mayor número de estudios dendroecológicos son Estados Unidos de América, España y Argentina. Las prácticas de manejo que fueron mayormente beneficiadas con el uso de métodos dendroecológicos son la estimación del tiempo de turno en la fase de planeación. el aclareo en la fase de ejecución. y las evaluaciones de crecimiento y rendimiento, así como los impactos de plagas y enfermedades sobre el crecimiento en la fase de monitoreo. La investigación en manejo forestal se sustenta principalmente en el seguimiento de parcelas permanentes de medición y puede ser fortalecida por el análisis de anillos de crecimiento. Los métodos dendrocronológicos proporcionan información relevante sobre la estructura del bosque, el estado fitosanitario, las tasas de crecimiento de especies arbóreas y su variación temporal. Las experiencias de la investigación dendroecológica llevada a cabo en otros países pueden aplicarse también en México, incluyendo el estudio de especies latifoliadas. El uso de la dendroecología como herramienta para el manejo forestal contribuiría a optimizar la producción maderable y favorecería la conservación de los ecosistemas forestales en el país.
