Abstract
Vegetation characteristics of Southern secondary moist mixed deciduous forest in the Agasthyamalai part of Kerala was assessed by random sampling through census quadrat method. Twelve localities were selected from Peppara W.L.S., Neyyar W.L.S. and Agasthyavanam Biological Park; 0.1 ha area were sampled from each locality totalling 1.2 ha. A total of 694 individuals (<15 cm GBH) belonging to 49 species and spreading over 29 families was recorded. Stand density, species density and basal area were 535 trees/ha, 12 species per 0.1 ha and 26.57/ha respectively. Plant diversity shows species richness of 2.81, concentration of dominance of 0.15, diversity 1.89 and evenness 0.73. The dominant association of this study area is Terminalia paniculata, Pterocarpus marsupium and Careya arborea. Among the three protected areas studied, Peppara W.L.S. shows comparatively higher stand density, basal area cover, species richness, diversity and evenness but compared to the other regions of the Western Ghats, the Agasthyamalai part shows lower values for basal area, species diversity and evenness.
