Carrying capacity and range condition of Hazargangi Chiltan National Park

ABSTRACT
This study was carried out during September, 1987 and
April 1988 in the Hazargangi-Chiltan National Park to
evaluate the effect of enclosure on carrying capacity,
rang trend and other vegetation characteristics. One
hundred twenty semi-permanent quadrats (plot) of 1
sq.m area both in fall 1987 and spring 1988 were laid
out at six representative sites along 400 meter long
transect line running across the contours. Out of these,
60 were clipped for estimation of forage production and
60 were studied for vegetation characteristics in two
seasons. The study reveled that enclosure had positive
effects on range vegetation. Vegetation recovery was
remarkably rapid. The decreasers (highly palatable)
species were reappearing. The estimated forage
production was 1234 Kg/per hectare, carrying capacity
was 1.1 ha / Markhor / annum and range condition (health) had
improved inside the enclosure. The study also suggested
detailed investigation on proper use-factor of different
forage/browse species, their palatability index and the
climax species in park.
