“…In the Kizildag forest management plan, a total of 2.18 Mt carbon is estimated to be stored with an average of 110 t ha −1 (GDF 2016). In another study conducted in the same enterprise, it was reported that the TCS was 1.97 Mt with an average of 120.8 t ha −1 (Dinç and Vatandaşlar 2019). Thus, our estimation fell between the values reported in the literature.…”

Forest ecosystems play a crucial role in mitigating global climate change by forming massive carbon sinks. Their carbon stocks and stock changes need to be quantified for carbon budget balancing and international reporting schemes. However, direct sampling and biomass weighing may not always be possible for quantification studies conducted in large forests. In these cases, indirect methods that use forest inventory information combined with remote sensing data can be beneficial. Synthetic aperture radar (SAR) images offer numerous opportunities to researchers as freely distributed remote sensing data. This study aims to estimate the amount of total carbon stock (TCS) in forested lands of the Kizildag Forest Enterprise. To this end, the actual storage capacities of five carbon pools, i.e. above- and below-ground, deadwood, litter, and soil, were calculated using the indirect method based on ground measurements of 264 forest inventory plots. They were then associated with the backscattered values from Sentinel-1 and ALOS-2 PALSAR-2 data in a Geographical Information System (GIS). Finally, TCS was separately modelled and mapped. The best regression model was developed using the HH polarization of ALOS-2 PALSAR-2 with an adjusted R2 of 0.78 (p < 0.05). According to the model, the estimated TCS was about 2 Mt for the entire forest, with an average carbon storage of 133 t ha−1. The map showed that the distribution of TCS was heterogenic across the study area. Carbon hotspots were mostly composed of pure stands of Anatolian black pine and mixed, over-mature stands of Lebanese cedar and Taurus fir. It was concluded that the total carbon stocks of forest ecosystems could be estimated using appropriate SAR images at acceptable accuracy levels for forestry purposes. The use of additional ancillary data may provide more delicate and reliable estimations in the future. Given the implications of this study, the spatiotemporal dynamics of carbon can be effectively controlled by forest management when coupled with easily accessible space-borne radar data.

“…Drought has a profound impact on most parts of Kizildag, particularly in the growing season. Thus, the region is classified as arid based on Erinç's aridity index (Erinç 1984;Dinç and Vatandaşlar 2019). According to Ozkan et al (2007), brown forest soils are ubiquitous in the forested lands of the basin where Kizildag is located.…”

Forest ecosystems play a crucial role in mitigating climate change as they are the largest carbon sinks. The objective of this study was to reveal the potential effects of forest dynamics on carbon sequestration and to contribute to planning studies. In this study, the changes in biomass and carbon storage areas in the 1999 and 2014 planning periods of the Çaltepe Forest Planning Unit. This calculation was carried out using widely accepted guidelines and coefficients, and the spatial distribution of biomass and C storage was mapped using GIS. As a result, the total biomass of the forested area increased by 53.42% in the period 1999-2014, from 781039.2 Mg to 1198263.51 Mg. On the other hand, the total amount of carbon storage increased from 1146019.35 Mg to 1448400.56 Mg in the period 1999-2014, an increase of about 26.39%. The contributions to the carbon (C) pool came from soil organic carbon with 60.12% and 53.28% of total C storage; from aboveground with 26.64% and 32.38%; from belowground with 7.66% and 9.27%; from litter with 5.33% and 4.77%; and from deadwood with 0.25% and 0.30% in 1999 and 2014, respectively. The average annual C sequestration was 1.95 Mg ha-1 yr-1, of which 1.06 Mg ha-1 yr-1 occurred in aboveground, 0.53 Mg ha-1 yr-1 in soil, 0.3 Mg ha-1 yr-1 in belowground, 0.05 Mg ha-1 yr-1 in litter and 0.01 Mg ha-1 yr-1 in deadwood. Results have shown that; to increase the amount of biomass and carbon sequestration capacity in forest areas, it is necessary to increase maintenance activities, select appropriate species in afforestation areas, and ensure sustainable carbon management by reducing social pressure on forests. As long as the sustainability of carbon pools on land is ensured, the effects of climate change will be mitigated.

Üst ölçekli planlama kapsamında orman ekosistemlerinde karbon tutumunun hesaplanması ve değerlendirilmesi, ormancılık faaliyetlerinin sürdürülmesi ve izlenmesi açısından önemlidir. Sürdürülebilir ve karbon odaklı ormancılık faaliyetleri karbon tutumunun düşük olduğu alanlarda, doğal ekosistem yapısına zarar vermeden karbon tutumunu artırmakta ve sera gazlarının azaltımına ilave katkı sağlamaktadır. Bu çalışmada Türkiye’nin Akdeniz Ekolojik Bölgesi’ndeki ormanlar için mevcut karbon tutumu, meşcere hacim değerleri ve uluslararası kabul görmüş katsayılar kullanılarak hesaplanmış ve haritalandırılmıştır. Çalışmada (1) orman idari sınırları için yapraklı ve ibreli ağaç türlerinin hektardaki ortalama karbon stok değerleri, (2) tüm bölgedeki yapraklı (saf ya da yapraklı ağaç türü ağırlıklı) ve ibreli (saf ya da ibreli ağaç türü ağırlıklı) meşcereler için hektardaki ortalama karbon stok değerleri, (3) kızılçam [Turkish red pine (Pinus brutia Ten.)] ve karaçam [black pine (P. nigra Arnold)] için çağ ve kapalılığa göre hektardaki ortalama biyokütle karbon stok değerleri hesaplanmıştır. Orman İşletme Şefliklerindeki orman meşcere türlerine göre ortalama toprak üstü biyokütle karbon stoku normal kapalı ibreli meşcereler için 36,12 ton C/ha ve normal kapalı yapraklı meşcereler için 20,13 ton C/ha’dır. Kızılçam için Çzde3 ve Çze3 meşcereleri ve karaçam için Çkde3 ve Çke3 meşcereleri en yüksek karbon tutumunu sağlamaktadır. Bu çalışmanın sonuçları, ekosistemlerin doğal yapısının da gözetilerek karbon stoku (depolaması) açısından ağaç türü seçiminde ve silvikültürel uygulamaların belirlenmesinde kullanılabilecektir. Bunun dışında meşcerede baskın olmayan türlerin karbon stok potansiyeli ilk kez bu çalışmada değerlendirilmiştir. Bu bilgi, bu türlerin karışımlarda korunmasını destekleyecektir. Son olarak, karbon yönetiminde yutak alanların ve karbon tutumunun artırılmasına yönelik çalışmaların artırılması ve önlemlerin alınması ya da sorunlara müdahale edilmesi gibi faaliyetlerde şeflikler arasındaki meşcere karbon stok farklarının gözetilmesini de sağlayacaktır.
