Pinus gerardiana is considered an important species
in dry temperate forests of North-Western Indian
Himalaya because of its influence on ecological processes
and economic dependence of local people in the region. But,
large numbers of biotic and abiotic factors have affected
P. gerardiana in these forests; hence, there is a crucial need
to understand the regeneration dynamics of this tree species.
The present investigation was conducted in P. gerardiana forests
to understand vegetation pattern and regeneration processes
on different sites in the region. Statistical analysis was
performed to know variability in growing stock and regeneration
on sample plots, while correlation coefficients and regression
models were developed to find the relationship between
regeneration and site factors. The vegetation study showed
dominance of P. gerardiana, which is followed by Cedrus
deodara, Pinus wallichiana and Quercus ilex in the region.
The growing stock of P. gerardiana showed steep increasing
and then steadily declining trend from lower to higher
diameter class. The distribution of seedling, sapling, pole and
trees was not uniform at different sites and less number of plots
in each site were observed to have effective conditions for continuous
regeneration, but mostly showed extremely limited
regeneration. Regeneration success ranging from 8.44 to
15.93 % was recorded in different sites of the region, which
suggests that in different sites regeneration success is influenced
by collection of cone for extracting seed, grazing/browsing and
physico-chemical properties of soil. Regeneration success
showed significant correlation and relationship with most of
abiotic and biotic factors. The regeneration success is
lower than the requirement of sustainable forest, but
varies widely among sites in dry temperate forests of
Himalaya. More forest surveys are required to understand
the conditions necessary for greater success of P. gerardiana
in the region.
