In the northern hemisphere, the north face of the mountains has a high diversity of species which is attributed to the moist and shady conditions at the north face. Other environmental variables may also influence the species diversity on the northern faces of the mountain and therefore needs to be studied in detail. The northern slopes represent three different sub-slopes—north, north east, and north west. During the current investigation of Pir-Panjal and Dauladhar ranges in Bhadarwah valley, fine-scale studies on the relationship between vegetation and four variables (soil pH, moisture content, electrical conductivity, and steepness) were conducted. The study determined the role of these variables on the vegetation of three different sub-slopes. The sampling was done at the confluence of two communities (forest and grassland) at three sites on the northern sub-slopes of the lesser stratum in western Himalayan. The result revealed that rich herbaceous diversity prevails on the lesser Himalayan stratum (Bhadarwah valley). As many as 65.8% species differ from site to site, whereas species commonality among the sites is minimum. The role of environmental variables on the species composition at different sub-slopes of the north mountain face is deduced through canonical correspondence analysis (CCA). The availability of solar light increases air and soil temperature on the north east–facing slope. All the environmental variables (soil pH, moisture, electrical conductivity, and mountain steepness) are insignificant at pure north face for the species composition. Therefore, it can be concluded that some other environmental variables may influence the species composition which are needed to be further investigated.

喜马拉雅西部交错带北亚坡草本气管植物分布的环境变量

在北半球，山脉的北面具有高度多样性的物种，这归因于北面的潮湿和阴暗条件。其他环境变量也可能影响山脉北面的物种多样性，因此需要详细研究。北坡代表三个不同的子坡-北，东北和西北。在目前对Bhadarwah谷的Pir-Panjal和Dauladhar山脉的调查中，进行了关于植被与四个变量（土壤pH，水分，电导率和陡度）之间关系的精细研究。研究确定了这些变量对三个不同亚坡植被的作用。采样是在喜马拉雅西部小地层北亚坡的三个地点的两个社区（森林和草地）的汇合处进行的。结果表明，在较小的喜马拉雅地层（Bhadarwah谷地）普遍存在丰富的草本多样性。站点之间多达65.8％的物种不同，而站点之间的物种共性最小。通过典型对应分析（CCA）推论了环境变量对北山区不同亚坡物种组成的作用。太阳光的可利用性使朝东北的山坡上的空气和土壤温度升高。对于纯净的物种组成，所有环境变量（土壤的pH值，湿度，电导率和山坡度）都不重要。因此，
