The present paper deals with phenology of selected tree species like Phyllanthus emblica, Dalbergia paniculata, Hardwickia binata, Anogeissus latifolia, Albizia thompsonii, Chloroxylon swietenia, Diospyros melanoxylon, Givotia moluccana, Buchanania axillaris, Terminalia alata, Sterculia urens, Strychnos nux-vomica, Bombox ceiba, Butea monosperma, Madhuca indica, Eriolaena lushingtonii, Albizia odoratissima, Terminalia bellirica, Pterocarpus marsupium, Firmiana colorata, Careya arborea in Amrabad Tiger Reserve, Telangana, India. The phenological observations include leaf flush, leaf mature, leaf fall, leaf less periods, flowering, fruiting, fruit fall, among the selected tree species. A total of ten individuals (鈮?0 cm gbh), for each of the selected 21 tree species were observed at fifteen days interval during 2018-2020 . It was observed that there were species specific phenophases relationship with deciduous period and initiation of seasonal rainfall and warm periods. In addition, intra species asynchrony in phenological activities was also recorded Leaf flush activity was initiated in March and . reached peak in the month of April and completed before the initiation of South-West monsoon. Leaf maturity started in the month of May and peak was recorded in June and completed in September. Leaf fall activity was initiated in the month of November and reached peak in January before the arrival of intense dry period. Deciduous period was recorded in December to April and the peak period was recorded in February. The reproductive phenophases like Flowering, Fruiting and Fruit fall have significantly varied across the different seasons among the observed tree species. Majority of tree species (43%) revealed synchronous flowering with Leaf flush activity. The results indicate that Leafing (48%) and flowering phenophases (70%) occur during the dry period before the onset of first rains and fruiting, fruit fall timing was in consequence to utilize the growing season. Thus, species specificity was recorded with respect to Phenophases were found to be in relation with the seasonal rainfall distribution and in turn soil moisture availability in the study area.
