Distribution Pattern and Phytosociological Attributes of Understory Vegetation in Different Agroforestry Systems of Kashmir, India

The investigation was carried out in seven different silvipastoral systems viz Cedrus deodara, Robinia pseudoacacia, Cupressus torulosa, Prunus arminiaca, Ailanthus altissima, mixed plantations and grassland (control).There were 12 shrub and 43 herb species in all the systems.Among shrubs, and among herbs, were observed in all the systems.Maximum height (23.91 m) Berberis lycium, Cyanodon dactylon and maximum dbh (91.72 cm) was for the trees in and system, respectively.The highest density Robinia pseudoacacia Cupressus torulosa (8133 shrubs/ha) was in grassland (control) followed by mixed plantations> Prunus arminiaca>Robinia pseudoacacia> Cupressus torulosa.The highest density for (86666 tillers/ha) and lowest (10000 tillers/ha) was recorded for .The basal area Cyanodon dactylon Stipa sibirica (m ha ) of herbage in different treatments showed the precedence grassland (control) followed by 2 -1 Prunus arminiaca>Robinia pseudoacacia> Ailanthus altissima.Cyanodon dactylon Importance value index of different herbage species in different silvipastoral systems revealed that was the dominating species under grassland (control), and mixed plantations system.was dominating Ailanthus altissima Oxalis acetosella under .was dominating species under mixed plantations, and Cedrus deodara Lolium perenne Robinia pseudoacacia Prunus arminiaca agroforestry systems.
