Abstract

Leaf phenology tree species of dry deciduous and evergreen forests of Bhadra Wildlife Sanctuary (13°25’ and 13°50’ N, 75°15’ and 75°50’ E) was studied during June 2004 to May 2006. Leaf fall starts in September and with a peak in December and January. Leaf initiation starts in February and with a peak in April before monsoon, while leaf expansion starts in February with a peak in May and July during monsoon in dry deciduous forest. In evergreen forest, leaf falling and leaf initiation was observed in one or the other species with a peak in January to February, leaf expansion too observed throughout the year with a peak in January and April before monsoon. Varying leaf phenology of these forest types is dependent on a regional rainfall pattern.

Key words: Bhadra Wildlife Sanctuary, dry deciduous forest, evergreen forest, leaf phenology, seasonality.
