ABSTRACT
Experiments were conducted to study microclimate and
natural regeneration of Abies pindrow in the moist
temperate forests of Pakistan at Kund. It has been
concluded that tree and vegetative cover from Viburnm
and Tree plus viburnm greatly affects the PAR levels
reaching seedlings. Under these conditions, the quantity
of PAR reaching at seedlings height was reduced to 2-4%
of total PAR received in the open conditions. After
seeds germinate, mortality rates of 1 to 3 year old
seedlings are high. The mortality rate of 1, 2 and 3
year old seedlings are high. The mortality rate of 1, 2
and 3 year old seedlings observed after 3 years were 88,
60 and 70% in open while 79, 82 and 69% in shade
respectively. Survival rate of 4 to 7 years old
seedlings is less affected in the open. Height growth is
slow, only 4.7 cm observed over three years (1.6
cm/year) in 7 years old seedlings, is normal for many
species of Abies. This paper discusses the effects of
vegetation cover ground conditions and grazing on the
establishment and survival of the natural regeneration.
