One hundred and eight species of macrohymenopterans belonging to fifteen families and fifty six genera were recorded from the Silent Valley
National Park. The families Sphecidae, Formicidae, Pompilidae and Apidae contained maximum number of species. The insects were collected from five habitats, viz., tropical evergreen forest, subtropical broad leaved hill forest, montane wet temperate forest, low altitude grasslands and high altitude grasslands. Of the various species recorded in this study, seven genera and eleven species are new reportsfor Kerala and seven species are new reports for India.
Bambusa bambos has been successfully planted in India to increase the productivity of bamboos. To prepare the biomass models for this species, equations were selected to estimate the green weight of tire whole bamboo culm, weights of the branches, leaves, and rhizomes. Diameter and height (DH) were found to be closely correlated with total above ground biomass and therefore selected for tire prediction of total biomass.
