    abstract = {The study of various periodic behaviours of
plant species or the phenology has great significance
because it not only provides knowledge about the plant
growth pattern but also provides the inferences on the
effect of environment and selective pressure on flowering
and fruiting behaviour. In this study,an attempt has
been made to record such data regarding periods of
leaf fall, leaf flushing, flowering, fruiting and all. This
was done for a period of two years for two species viz.
<i>Picrorhiza kurroa</i> and <i>Saussurea costus</i> of course
which were somehow having medicinal properties and
it was carried out in the VCGS UUHF Bharsar
district of Pauri, Uttarakhand. In the study the leaf fall
peak period was found in last part of December, leaf
flushing peak period in the month of march where as
flowering and fruiting activity peak period was found
during the month of May-June and July-August,
respectively. So, this type of study will be helpful to give
inferences in future whether the of climate change are
giving pressure on the periodic behaviour of plant species.
Changed phenological behaviour of plant species
indicates the losing of plant diversity of the district in a
critical level.}
