Structure, composition and distribution pattern of agroforestry flora along altitudinal gradient in Kirtinagar block of district Tehri Garhwal, Uttarakhand, India

In this study, we investigated phytosociological attributes of traditional agroforestry systems in Kirtinagar Block of Tehri Garhwal, Uttarakhand, India. The objective of this study was to explore and compare phytosociological attributes along the altitudinal gradient of traditional agroforestry components species. Three different indigenous agroforestry systems i.e. agri-silviculture, silvi-pasture and homegarden were selected for documentation of agrobiodiversity through quadrat method. Further, density, frequency, IVI, and abundancefrequency ratio was calculated for each component of agroforestry system. The study reported that Grewia optiva, celtis australis, Mallotus phillipensis, Citrus sinensis and Morus alba were the most dominant tree species in the area.
