Effect of Altitudinal Gradation on Regeneration Status of NTFP Species in Central Western Ghats of Karnataka
Abstract
The regeneration is the important criteria for the growth and survivability of forests and he current study was conducted to observed the regeneration status of NTFP species along altitudinal gradation in central Western ghats. Quadrate sample plot method was adopted for collection of data. the regeneration diversity of Psychotria flavida with an Important Value Index (IVI) value 22.8, Knema attenuate 23.52 and Murraya paniculata 8.81 was dominated in coastal, midghat and plane zone respectively, followed by Hopea ponga in Coastal and midghat zone and Caryota urens in Plane zone. In Family Importance Value (FIV) of Rubiaceae (33.60) recorded highest in coastal, Myristicaceae (19.50) in midghat zone and Rutaceae (16.57) in plane zone. Among the size class distribution for all the species in different altitudinal ranges, the decreasing trend of stems of lower size to higher size class exhibiting a reverse J-shape curve graph indicating promising growth of regenerating species.
