Abstract

Phenology of tree layer species from the timber line of Kumaun in Central Himalaya was carried out during the years 1988-1989. The study indicates the prevalence (66%) of deciduous tree species at timber line vegetation. Growth initiation started in early summer with the rise of temperature. Different phenophases succeeded one another, culminating in leaf drop with the advent of winter. The various phenophases of the tree species at timber line have been discussed and compared with the lower Himalayan forests of Kumaun in India. The present study also supports the idea that the intense fluctuations in environmental conditions determine the onset of different growth activities within the short growing season.
