“…However, BA and Vol increased in the genera Pinus and Quercus from FMP1 to FMP2 (Figure 3B,C), and, in the case of other broadleaf trees, it remained constant or did not differ noticeably. Intensive management such as the application of alternate strip clearcutting and thinning shows that, although NT decreases, Vol and BA tend to increase in the following cutting cycles due to greater spacing between individuals that reduces competition, to the litterfall that allows nutrients to be reincorporated into the forest floor, and to the capacity of the young stands to absorb these nutrients [39]. Forest growth is related to the level of forest site productivity and stand density.…”

“…This reveals the species diversity in each sub-stand, since the application of silvicultural treatments modifies the conditions of diversity and abundance of the tree species present [24,28,36]. This situation is not only present in intensive methods; Solís-Moreno et al [45] recorded that, in the forests of Durango, Mexico, the single-tree selection method also decreased tree diversity, since Intensive management such as the application of alternate strip clearcutting and thinning shows that, although NT decreases, Vol and BA tend to increase in the following cutting cycles due to greater spacing between individuals that reduces competition, to the litterfall that allows nutrients to be reincorporated into the forest floor, and to the capacity of the young stands to absorb these nutrients [39].

In the middle of the last century, the Mexican government applied a forest administration policy based on state control through concessions to parastatal enterprises. In the 1980s, communities began to regain control of their forests and promote community forestry, with Ixtlán playing a leading role. This study compared three forest management plans (FMPs) that have been implemented in the community of Ixtlán de Juárez, in southern Mexico, and their contributions to the productivity and conservation of forest resources. The information was obtained from three FMPs, considering the silvicultural regimes, the original stand or sub-stand structure, and the species that promoted cutting regeneration. These FMPs represent different management periods; the forest inventory of the first FMP indicates the condition of the forest originated under state control, while the two subsequent ones evaluate the condition of the forest under community forestry. Sub-stand variables of the three FMPs were compared using the nonparametric Kruskal–Wallis test. The results indicated that, in the first FMP, the sub-stands were of old growth, and intensive thinning was applied. In the two subsequent plans, alternate strip clearcutting and single-tree selection were implemented. It was shown that, with increased management intensity in the sub-stands, better characteristics were obtained in terms of increment in basal area and volume variables, promoting regeneration and establishment of Pinus and displacing dominance of Quercus genus, without affecting forest richness and diversity.

Bu çalışma Marmara Bölgesi’ndeki doğu kayını ormanlarında gelişim çağlarına göre dökülme miktarlarını ve bu yolla ölü örtüye giren karbon stoklarını ortaya koymak amacıyla yapılmıştır. Denemeler, b (d1,3=8,0-19,9 cm), c (d1,3=20,0-35,9 cm) ve d (d1,3=36,0-51,9 cm) gelişim çağında bulunan, bakı, yükselti, eğim, yamaç konumu ve meşcere gelişimi bakımından farklılık gösteren toplam 18 alanda tesis edilmiştir. Her deneme alanına beş adet 50×50 cm ebadında kapan kurulmuş ve üç yıl boyunca aylık olarak dökülme materyalleri toplanmıştır. Araziden alınan dökülme materyalleri laboratuvarda bileşenlerine (yaprak, dal, kabuk, diğer) ayrılarak 65 °C’de sabit ağırlığa ulaşıncaya kadar kurutulmuş ve tartılmıştır. Daha sonra öğütülen örneklerde karbon analizi yapılmıştır. Kapanlardan elde edilen dökülme bileşenlerine ait kütleler hektara çevirme katsayısı kullanılarak bir hektar alandaki dökülme miktarları elde edilmiş daha sonra bu değerler analizler sonucu elde edilen karbon yoğunlukları ile çarpılarak bir hektar alanda dökülme sonucu ölü örtüye katılan karbon stokları hesaplanmıştır. Elde edilen veriler varyans, korelasyon ve aşamalı çoklu regresyon analizleri ile değerlendirilmiştir. Araştırma sonuçlarına göre, gelişim çağının ilerlemesine bağlı olarak dökülme miktarı artmış ve toplam dökülme 3959 ile 5698 kg/ha/yıl arasında değişmiştir. Dökülmeye ait ağırlıklı karbon oranı %50,3 olarak belirlenmiştir. Toplam dökülme ile ölü örtüye giren C stoku gelişim çağlarına göre 1988-2857 kg/ha/yıl arasında değişmektedir. Kayın ormanlarındaki toplam dökülme meşcere özellikleri, iklim özellikleri ve fizyografik faktörler ile tahmin edilmiştir. Elde edilen modeller kullanılarak yöredeki ve benzer yetişme ortamlarındaki kayın meşcerelerinde yıllık dökülme miktarı tahmin edilebilir. Bu araştırma ile ortaya konulan bulgular arazi kullanımı, arazi kullanımı değişikliği ve ormancılık sektörünün uzun dönemli hedefleri arasında yer alan modelleme çalışmalarında kullanılabilir.
