“…In these studies, forest areas are generally located in areas with very low and moderate soil erosion risk (Beyramin et al, 2003;Oruk et al, 2012;Luo et al, 2014;Esmaeili Gholzom et al, 2022). This contrary situation in the study area can be attributed to both low vegetation density and very high erodibility in forest areas (del Campo et al, 2022). In this context, when the forest management plan was examined, it was determined that 58.4% of the forest areas have crown closure with 0 and 1, while 24.97% of them have crown closure with 2.…”

Barajlar birçok ülke için ekonomik kalkınmanın kritik bir bileşeni haline geldiğinden, baraj havzalarındaki toprak erozyonu çok önemli bir olgudur. Dolayısıyla, Akdeniz bölgesinde gerek orman yangınlarında gerekse şiddetli yağışlarda beklenen artış baraj havzaları için tehdit oluşturmaktadır. Bu iki olgudaki artış baraj havzalarında orman yangınları sonrası toprak erozyonunda ciddi bir artışa neden olacaktır. Bu nedenle orman yangınlarının toprak erozyonu riski üzerindeki olası etkilerinin ortaya konulması, baraj havzalarının yönetiminde proaktif önlemlerin alınması açısından son derece faydalı olacaktır. Bu bağlamda bu çalışma Ayvalı baraj havzasında toprak erozyonu riskini ortaya koymayı ve olası orman yangınlarının toprak erozyon riski üzerindeki etkisini belirlemeyi amaçlamaktadır. Çalışma alanındaki toprak erozyonu riskini belirlemek için ICONA modeli kullanılmıştır. Orman yangınlarının etkisi senaryo analizi ile belirlenmiştir. Orman yangını senaryosunda, çalışma alanındaki tüm ormanların yandığı varsayılmıştır. Bu senaryo dikkate alınarak ICONA modeli ile yeni bir toprak erozyonu risk haritası oluşturulmuştur. Daha sonra bu iki harita karşılaştırılmıştır. Sonuçlar, çalışma alanının %70,33'ünün çok yüksek erozyon riskine maruz kalırken, %21,65, %7,19, %0,77 ve %0,05'inin sırasıyla yüksek, orta, düşük ve çok düşük erozyon riskine maruz kaldığını göstermiştir. Çalışma alanındaki bu çok yüksek erozyon riski yüksek eğim, yüksek toprak aşınabilirliği ve seyrek bitki örtüsü yoğunluğundan kaynaklanmaktadır. Yangın senaryosu sonucunda çok yüksek riskli alanlar %18,11 artarken, yüksek, orta, düşük ve çok düşük riskli alanların sırasıyla %48,55, %26,36, %35,43 ve %100 azaldığı tespit edilmiştir. Elde edilen bulgular, orman yangınları öncesi ve sonrasında toprak erozyonu potansiyeline bağlı olarak gerekli önlemlerin önceliklendirilmesi konusunda karar vericilere yol gösterici olabilir.

“…In a review paper, Del Campo et al [35] synthesized the results of several works analyzing the impact of thinning on key hydrological dynamics, particularly focusing on rainfall distribution, soil moisture levels, and evapotranspiration processes. As a result, a thinning intensity of about 50% (between 40% and 60% for a confidence interval equal to 95%) of the stand density has been identified as the threshold at, or over, which the hydrological processes are affected.…”

The concept of integrated forest management offers a framework for understanding how forest ecosystem services interact with efforts to conserve natural resources. Forests face various disturbances stemming from human activities, management approaches, and shifts in climate patterns. This study aims to explore how forested watersheds respond to diverse silvicultural practices amidst changing climate conditions. The research is centered in the Bonis catchment, situated in the mountainous region of Sila Greca (latitude 39°25′15″ N, longitude 16°12′38″ W) within Southern Italy’s Calabria region. Nearly 93% of the catchment area is cloaked in a forest dominated by approximately 50-year-old Pinus laricio Poiret stands. To model the catchment’s response to various climate and management scenarios, the FEST-FOREST eco-hydrological model, which is distributed and based on physical principles, has been employed. This model accounts for the dynamic interactions between vegetation and the watershed’s hydrological processes. The monitoring of the basin has been ongoing since 1986, with runoff measurements collected at the catchment outlet using dedicated gauging structures. These data have been utilized to calibrate and validate the model, ensuring its accuracy in simulating future scenarios. These simulation results offer stakeholders some qualitative and scientifically based recommendations for the sustainable management of the catchment. In fact, thinning intensity affects hydrological processes, with a 50% stand density reduction identified as a threshold for significant impact on processes like rainfall partitioning and evapotranspiration. Under heavy thinning scenarios, runoff can change by over 60%, and the impact decreases with larger thinning intervals. Furthermore, different climate scenarios influence stem yield levels, with higher production under RCP 4.5 and RCP 8.5 compared to the base climate scenario. In particular, the RCP 8.5 scenario produces the highest yield due to better forest growth under different climate scenarios. This implies the idea that in regions with a Mediterranean climate and coniferous forests, amidst climate change, meticulous forest management involving precisely calibrated thinning schedules and intensities, tailored to unique biotic and abiotic factors, could potentially enhance carbon sequestration while positively influencing runoff rates.

“…Nevertheless, the resistance of a coppice stand can be also affected by silvicultural practices. For example, forest thinning can increase throughfall, reduce competition between individual trees, and promote the growth and water use of remaining trees ( Rodríguez-Calcerrada et al 2011 ; del Campo et al 2022 ).…”

Recent changes in water availability can be crucial for the development, growth, and carbon budget of forests. Therefore, our aim was to determine the effect of reduced throughfall and severe summer drought on stem CO2 efflux as a function of temperature and stem increment. Stem CO2 efflux was measured using the chamber method on oak and hornbeam under four treatments: coppice, thinned-coppice, and both coppice and thinned-coppice with 30%-reduced throughfall. The first year of the experiment had favourable soil water availability and the second year was characterized by a dry summer. While reduced throughfall had no effect on stem CO2 efflux, the summer drought decreased efflux by 43-81% during July and August. The stem CO2 efflux was reduced less severely (by 13-40%) in September when the drought persisted but the stem increment was already negligible. The stem increment was also strongly affected by the drought, which was reflected in its paired relationship with stem CO2 efflux over the two experimental years. The study showed that summer dry periods significantly and rapidly reduce stem CO2 efflux, whereas a constant 30% rainfall reduction needs probably a longer time to affect stem properties, and indirectly stem CO2 efflux.
