Structure, composition and regeneration of riparian forest along an altitudinal gradient in northern Iran

摘要: In order to protect and understand the regeneration of riparian forests, it is important environmental conditions that lead their vegetation differentiation. We evaluated structure, composition, density woody species in forests along river Safaroud Ramsar forest northern Iran relation elevation, soil properties distance from river. Using 60 transects located perpendicularly 300 quadrats, we examined 0, 50, 100, 150 200 m stream an elevation gradient spanning 350 2,400 a.s.l. found total density, regeneration, diameter basal area trees were significantly higher interior whereas shrub was close The uneven-aged structure showed no significant differences among interior. Hydro-geomorphic processes, flooding, gradient, most factors influenced plant community distribution
