Abstract

The study was carried out on the growth, distribution, classification and correlation of herbaceous vegetation edaphic factors in Margalla Hills National Park, Islamabad. Sampling of vegetation and soil was performed using random sampling method. A total of 52 herbaceous plant species from 26 families were recorded in 30 quadrats. The study aimed to classify and identify plant species and to understand the soil factors playing role in community composition. TWINSPAN was used to identify distinct plant communities, which resultedin the recognition of four vegetation groups. Malvastrum coromandelianum and Cicer arietinum community was present along the agricultural crop fields, Cynodon dactylon and Cerastium fontanum community occupied the humid stands, Micromeria biflora and Grewia tenax community was present in a majority of areas. Lepidium pinnatifidum and Coronopus didymus community was grown along the road in the study area. DCA was used to determinethe dominant communities in the study area. Understanding vegetation distribution in this area can help for management, reclamation, and development of Margalla Hills National park ecosystems

Pakistan İslamabad Margalla Hills Milli Parkı’ndaki otsu vejetasyonun ordinasyonu ve sınıflandırılması

Abstract

İslamabad Margalla Hills Milli Parkı otsu vejetasyonunun toprak faktörlerine göre gelişmesi, dağılışı, sınıflandırılması ve karşılaştırılması yapıldı. Vejetasyon ve toprak örneklemeleri rastgele örnekleme metoduna göre yapıldı. Alınan 30 örnek parselden toplam olarak 26 familyaya ait 52 otsu bitki türü kaydedildi. Çalışmanın amacı vejetasyondaki bitki türlerini tespit etmek ve bitki topluluklarının kompozisyonlarında toprak faktörlerinin rölünü anlamak. Açıkca görülebilen dört vejetasyon grubuna ait bitki topluluklarının belirlenmesi TWINSPAN kullanılarak yapıldı. Malvastrum coromandelianum ve Cicer arietinum topluluğu ekin tarlaları boyunca yer almakta, Cynodon dactylon ve Cerastium fontanum topluluğu nemli alanlarda bulunmakta, Micromeria biflora ve Grewia tenax topluluğu alanın büyük bir kısmını kaplamakta. Lepidium pinnatifidum ve Coronopus didymus topluluğu çalışma alanındaki yol kenarlarında gelişmekte. Çalışma alanındaki baskın topluluğu tespit edebilmek için DCA kullanıldı. Vejetasyonun alandaki dağılışının anlaşılması Margalla Hills Milli Parkı ekosistemlerinin yönetimine, gelişimine ve daha iyi değerlendirilmesine yardımcı olabilir
