Tree growth characteristics, soil parameters, and soil organic carbon of highland <i>Juniper</i> and <i>Acacia</i> forests in Southwestern Saudi Arabia.

ABSTRACT: Variation in SOC affects the global carbon cycle and climate change and it also determines differences in soil fertility and consequently the plant communities growing in different habitats. The overall goal of this study is to determine variation in SOC in the soils associated with two trees that dominate forests in the highlands of southwestern Saudi Arabia. Juniperus procera dominates forests at higher elevation sites and Acacia gerrardi dominate forests at lower elevations in these highlands. Soils of the J. procera study site had significantly higher mean values for SOC content and SOC density, compared to the mean values of the A. gerrardii study site. The mean value of SOC stock at the J. procera study site was higher than that of the
