Abstract: The phenological studies of two tree species Shorea robusta Gaertn. f. and Ficus hispida L.f. occurring in Katerniaghat Wildlife Sanctuary (KWS), a tropical moist deciduous forest in Northern India along Indo-Nepal border has been carried out to gather information about the different phenophases of the plants. Both the candidate species are the co-dominant constituents of the sanctuary area. For each species ten trees were selected and a total of 160 twigs were tagged to collect phenological data. The initiation and completion of different phenophases such as leaf bud initiation, leaf emergence, young leaf formation, leaf fall, flower bud development, formation of flowers and fruits were recorded at monthly basis. In addition, the number of leaf buds, young leaves, matured leaves and total leaves has also been recorded. The individual leaf area was measured by using graph paper once they became stable in their growth and ultimately average leaf area was obtained. In both the species leaf bud busting and flowering/figing initiate in post winter (March to April) and maximum leaf fall was recorded in the post monsoon season (November to February). In Shorea robusta the young fruits start to appear in dry season (May) and get matured before the arrival of the monsoon (June) so that the seeds get proper moist condition to germinate.
