Structure and Regeneration Patterns of Pinus gerardiana (Wall. ex Lamb) Forest Zhob District, Balochistan, Pakistan

The aim of this study was to examine the Structure and Regeneration Patterns of Pinus gerardiana (Wall. ex Lamb) Forest Zhob District, Balochistan. The study was conducted during July and August 2018 in Zhob District, Balochistan. Different parameters included, basal area m² ha-1, density ha-1, physical condition, floristic composition, physio-chemical of soil and sex distribution, were determined through standard techniques. Results indicated that’s in field area herbs, shrubs and although grasses were found 50%, 37% and 13%). The average density was 321 ha-1 with a range from 15 to 717 of trees ha-1 and with an average 378 basal area m²ha-1. Basal area and trees density of Chilghoza were significantly correlated (r= 0.37) at 0.001 significant level. A complete seedling density (<6 cm) was found from 113 to 947 ha-1 with an average (448) ind/ha, varied considerably. Population of sex ratio displayed 44 % bisexual with a prevalence of denomination, followed by male 36% while female was 20%. Soil characteristics indicated that the soil was free from salinity, basic in reaction and calcareous in nature.
