In the recent decades, regeneration patterns of forest species have played an important role in mitigating future climate impacts. This study analysed impact of disturbances due to grazing on the regeneration status of temperate reserve forest species in Churdhar Wildlife Sanctuary, Himachal Pradesh, located in Western Himalaya of India spanning a wide range of altitudes. For analysis of vegetation, quadrat method was used to assess regeneration status and level of disturbance (grazing intensity). We found that seedling and sapling density and species richness decreased with increasing altitude. Overall, a fairly good regeneration potential was observed for tree species, and few of them reported poor regeneration exclusively due to grazing disturbances at higher altitudes. The forest growing at lower altitudes showed better regeneration than the forests growing at higher altitudes. Majority of dominant and co-dominant tree species showed a reverse j-shaped curve, but Quercus semecarpifolia and Rhododendron arboreum showed an inverse j-shaped curve. The study concluded that poor regeneration of species at higher altitude could be attributed to grazing and harsh environmental factors and, therefore, recommends adoption of suitable management measures at different phases of forest reproduction for successful forest establishment.

近几十年来，森林物种的更新模式在减轻未来气候影响方面发挥了重要作用。本研究分析了放牧干扰对位于喜马偕尔邦喜马偕尔邦丘尔德哈尔野生动物保护区温带保护区森林物种再生状态的影响，该保护区位于印度喜马拉雅西部范围广泛的海拔高度。对于植被分析，使用样方法评估更新状态和干扰程度（放牧强度）。我们发现苗木密度和物种丰富度随着海拔的升高而降低。总体而言，对树种观察到了相当好的再生潜力，很少有人报告说由于高海拔地区的放牧干扰而导致再生不良。生长在低海拔的森林比生长在高海拔的森林表现出更好的更新。大多数优势树种和共优势树种呈倒 j 形曲线，但Quercus semecarpifolia和Rhododendron arboreum呈倒j形曲线。该研究得出的结论是，高海拔地区物种更新不良可归因于放牧和恶劣的环境因素，因此建议在森林繁殖的不同阶段采取适当的管理措施，以成功建立森林。
