Soil samples were collected by dividing each main plot area into five areas each 10 x 10 m.

Soil organic carbon stock was calculated using equation of Nelson and Sommers (1996), Soil Organic Carbon stock = ([Soil bulk density (g cm-3) x Soil depth (cm) x Carbon (%)] x100.
Bulk density of soil was estimated through specific gravity method (Singh, 1980).
Similar results have been reported earlier (Chisanga, 2012; Bhardwaj et al., 2013). Soil organic carbon stocks: The soil organic carbon was significantly influenced by land use system, altitudinal range and soil layer effect. Key Words: Endangered species, Medicinal plants, Rheum australe, Seed germination Oln y Current estimates by the Threatened Plants Species Committee of the Survival (TPSSC) of IUCN indicate that 1 in 10 species of vascular plants on earth is endangered or threatened due to commercial exploitation and increasing international trade.
Slower decomposition means less mineralization and hence losses of organic carbon through erosion will be lower at higher altitude and hence more carbon content conservation. Maximum germination percentage, early initiation and completion of germination, maximum mean daily germination and maximum peak value was under shade net house conditions and soil cocopeat vermicompost (1:1:1) media.
Low amounts of soil organic carbons stocks under the Bhalendra Singh Rajput, D. The increase or decrease in the soil organic carbon pool was associated with the bulk density and organic carbon content of the soil of a particular depth. Over 1748 species of medicinal and aromatic plants reported from IHR are used in different systems of medicines.
The abundant litter and/or pruned biomass returns to soil, combined with the decay of roots contribute to the improvement of organic matter under complex land use systems (Sharma et al., 2014). It may be due to sharp decline in the bulk density of the A2 and A4 soil layers The soil organic y carbon stock declines appreciably from 0-20 cm to 20-40 cm (Table 2). Labile carbon pools and soil organic carbon stocks in the foothill Himalayas under different land use systems. The Indian Himalayan Region (IHR) is a rich reservoir of biological diversity in the world. Indian Journal of Radiology and Imaging / February 2014 / Vol 24 / Issue 1. Lower organic carbon in agriculture land use system than grassland as recorded in our studies has also been reported by Pal et al. The organic carbon increased with increasing altitudinal range, which can be owed to continuous accumulation of leaf litter and slower decomposition rate at the higher altitude than at lower ones.

The increased organic carbon content in soils under tree based system may be ascribed to more leaf litter deposition and root turnover from trees (Dhillon et al., 2012). Estimation of soil organic carbon by chronic acid titration method. fo r M em be rs Sharma R, Chauhan SK and Tripathi AM 2015.

Composite samples from all sub area were obtained for each depth. The high value of bulk density in the soils can also be ascribed to lower soil organic carbon content. Soil samples for each sub area were obtained by digging five profiles of 20 x 50 cm (sub-surface area) by 50 cm deep. Dwivedi and Dileep Kumar 94 layer layers (Table 2) and under different land use system followed the decreasing trend i.e. It was observed that intensively managed land use system higher bulk density and it declined as the intensity of land management system declined. The current studies further revealed that agroforestry system types integrating fruit trees as woody perennial in place of forest/ fodder tree had higher bulk density value.
