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.
