Murree (Pakistan) çevresindeki oldukça bozulmuş iğne yapraklı ormanların vejetasyonu

Öz

Bu fitososyolojik araştırma, Murree tepeleri çevresindeki çeşitli bozulmuş ormanlarda yapılmıştır. Çalışmanın temel amacı topluluk türlerini, ilişkili zemin florasını ve toprak özellikleri ile ilişkilerini araştırmaktır. Sekiz bitki topluluğu ve iki monospesifik meşcere tanımlanmıştır: Pinus wallichiana (saf), Pinus roxburghii (saf), Pinus wallichiana-Quercus baloot, Pinus wallichiana-Cedrus deodara, Pinus wallichiana-Abies pindrow, Pinus wallichiana-Quercus dilatata, Quercus dilatat-Cedrus deodara, Pinus roxburghii-Pinus wallichiana, Pinus roxburghii-Cedrus deodara, Pinus roxburghii-Quercus dilatata. Pinus wallichiana 8 standda monospesifik olarak baskınken, 5 yerde bulunan Pinus roxburghii-Pinus wallichiana topluluk türleri. Pinus wallichiana, Cedrus deodara ve Abies ile 4 yerde ayrı ayrı topluluk oluşturmuştur. Pinus wallichiana-Cedrus deodara ve Pinus roxburghii-Quercus dilatata topluluğunda, yani 128 ağaç/saatte elde edilen en yüksek meşcere yoğunluğu olarak gözlenmiştir. Pinus wallichiana (saf) meşcerelerinden kaydedilen en yüksek bazal alan (48.06 (m²/ha) olarak kaydedilmiştir. Pusus wallichiana-Pinus roxburghii toplulukları ağaç yoğunluğu ile anlamlı bir şekilde korelasyon göstermiştir (p <0.05). DO. PH, Sıcaklık, İletkenlik, Tuzluluk, ORP her topluluk türündeki kimyasal parametreler de gösterilmiş ve tartışılmıştır.

Vegetation of highly disturbed conifer forests around Murree, Pakistan

Öz

This phytosociological investigation is conducted in various disturbed forests around Murree hills. The main purpose of study is to explore community types, associated ground flora and their relation to soil characteristics. Eight community types and two monospecific tree stands have been recognized as follows: Pinus wallichiana (pure), Pinus roxburghii (pure), Pinus wallichiana-Quercus baloot, Pinus wallichiana-Cedrus deodara, Pinus wallichiana-Abies pindrow, Pinus wallichiana-Quercus dilatata, Quercus dilatata-Cedrus deodara, Pinus roxburghii-Pinus wallichiana, Pinus roxburghii-Cedrus deodara, Pinus roxburghii-Quercus dilatata. Pinus wallichiana dominates monospecifically in 8 stands while Pinus roxburghii -Pinus wallichiana community types found at 5 locations. Pinus wallichiana formed community type with Cedrus deodara and Abies pindrow at 4 locations separately. Highest stand density achieved in Pinus wallichiana-Cedrus deodara and Pinus roxburghii-Quercus dilatata community i.e. 128 trees/h. Highest basal area (48.06 (m²/ha) recorded from Pinus wallichiana (pure) stands. Pinus wallichiana-Pinus roxburghii communities correlated significantly (p < 0.05) with tree density. Range of DO. pH, Temperature, Conductivity, Salinity, ORP and chemical parameters in each community type has also shown and discussed.
