  • Topographic and Edaphic Factors Shaping Floral Diversity Patterns and Vegetation Structure of Treeline Ecotones in Kumaun Himalaya
    Vandana Bisht, Subrat Sharma, Surendra Singh Bargali, Archana Fartyal
    Land Degradation and Development, 2025
    Treeline ecotones are ecologically sensitive ecosystems that are increasingly vulnerable to recent global warming and land degradation processes such as soil erosion, nutrient depletion, and organic matter loss. However, little is known about how floral diversity in treeline ecotones responds to changing environmental factors, particularly in the high Himalayan treeline ecotones. The present study examined the potential effects of topographic and edaphic factors on the vegetation structure of treeline ecotones of two mountain summits in Kumaun Himalaya. Using line transects, plots, and quadrats, we recorded 96 plant species from 72 genera and 36 families. Jaccard similarity coefficients revealed varying degrees of similarity in species composition between different aspects and elevations. Beta diversity analysis indicated nestedness as a dominant driver of community composition. Vegetation assessments showed shifts in tree density (ranging from 12.50 to 227.50 individuals per hectare), basal area (ranging from 0.138 to 9.855 square meters per hectare), and dispersion patterns along the elevational gradient. The dominant tree species across all treeline ecotone plots was Rhododendron arboreum. Regeneration was evident, with 69% of trees in smaller girth classes, indicating active recruitment. In addition to vegetation distribution, this study analysed soil characteristics across the treeline ecotones to assess potential land degradation trends. Soil temperature, pH, moisture, and water holding capacity decreased with elevation. South and east aspects had higher temperatures, pH, and phosphorus, while north and west aspects had higher moisture, organic carbon, and nitrogen. Results indicate that decreasing soil moisture, increasing bulk density, and declining total organic carbon at higher elevations and exposed aspects are indicative of degradation processes that may impact long‐term vegetation stability. The significant relationships between soil parameters and species distribution highlight the importance of understanding degradation dynamics in shaping floristic patterns. Non‐metric multidimensional scaling (NMDS) showed distinct clusters of treeline plots based on environmental variables (stress value: 0.17), while canonical correspondence analysis (CCA) demonstrated strong species‐environment correlations, explaining 83.08% of the total inertia. Given the observed soil degradation trends, conservation strategies should prioritize soil stabilization, erosion control, and nutrient depletion to mitigate the risks of ecosystem degradation. This research provides key insights into ecosystem resilience and serves as a foundation for monitoring treeline ecotones under changing environmental conditions.

    Journal of Applied Remote Sensing, 2023
    Advanced remote sensing technologies, such as light detection and ranging (LiDAR), offer significant potential to mapping the alpine treeline ecotone (ATE) based on its actual definition (tree height ≥ 3 m) and contribute to the generation of baseline data for future change detection investigations. We propose an approach for combining LiDAR-derived absolute tree height data with elevation data to delineate the ATE in Uttarakhand, India. The approach was implemented using observations from the recently launched Global Ecosystem Dynamics Investigation system and validated with field measurements. The LiDAR-derived treeline was compared with the traditional normalized difference vegetation index (NDVI) treeline. The treeline derived from LiDAR was found to have root mean square error of ∼60 m with respect to the ground verified treeline location. The NDVI treeline was overestimated in comparison to the LiDAR treeline by an average surface distance of 290, 232, 257, and 237 m in the south, north, west, and east aspects, respectively. It is observed that the overestimation was higher at the lowest and highest elevation zones. We prove that LiDAR-based treeline mapping is an efficient method to delineate alpine treelines at a landscape scale.

  • Functioning and sustainability of mid-elevation mixed agroecosystem depends on supply of energy from forest-ecosystem of the Indian Central Himalaya
    Bhawana Soragi, Subrat Sharma
    Handbook of Himalayan Ecosystems and Sustainability Volume 1 Spatio Temporal Monitoring of Forests and Climate, 2022
    Cropland is the nucleus of human settlements in the rural Himalayas where the flow of energy and ecosystem services from surrounding areas are vital for the functioning of the agroecosystem and agricultural production. The majority of the human population (~75% of the total) in the Himalaya is dependent on agriculture (largely rainfed cultivation on terraced hill slopes) while irrigated cultivation remains in valleys. Himalayan forests provide multiple benefits at various scales, ranging from local to global. Human and bullock labor and farmyard manure are significant energy inputs to sustain agricultural productivity in the Himalayan region. This study aims to estimate flow of forest goods to support agroecosystem. The annual energy input in agriculture is evaluated in terms of seed, labour (human and animal), and organic manure (~90% of total energy input). Among the crops, manure and seed input were found maximum for wheat. Among the different inputs, human labour input ranged from 0.05 to 2.60 Gkcal and bullock labour from 0.02 to 1.28 Gkcal. The total energy output ranged between 1.39 and 39.74 Gkcal for the different crops. The agronomic yield was highest for wheat and lowest for lentils. To maintain 1 unit of agronomic production from cropland and orchard, about 28 units of energy are required from nearby forests. No export of product or energy from agroecosystem is done to the forested landscape; however, for each energy unit imported from market to the agroecosystem, 2.7 energy units were exported. It was also observed that crop by-product values were more than agronomic yield values, which signifies the importance of traditional crops to maintaining livestock required for farmyard manure and draught power.
  • Extending winter cultivation in trans-Himalaya for agricultural sustainability The Potential of Geothermal Energy
    Rigzin Wangmo, Subrat Sharma
    Handbook of Himalayan Ecosystems and Sustainability Volume 1 Spatio Temporal Monitoring of Forests and Climate, 2022
    The majority of Indian cultivation is rainfed where food security is a critical issue due to various threats, including climate change. Therefore, mitigation measures play a significant role in reducing the risks imposed by climate change. Ladakh, one of the highest-altitude inhabited places on earth, is known for the existence of enormous sources of renewable energy, including geothermal. This Trans-Himalayan region is also known for limited seasonal agriculture due to prolonged sub-zero winters. Geothermal sites (Puga and Chumathang, altitude 3950m asl) are known for high enthalpy thermal manifestations. The scientific grasp of geothermal energy remains untapped in these high mountains. We performed a comprehensive review to discuss the potential use of geothermal energy for winter cultivation in the area, which remains landlocked from the rest of world throughout winters. The study sites lying north of the Indus Tsangpo Surture Zone are tectonically active, so the place is manifested with hot springs, mudpools and mild geysers. Local communities have seen direct benefits (cooking, bathing, and washing) from hot springs, but other uses have not been explored. A solution for winter cultivation at an altitude of ~4000m asl is possible through a simple and cost-effective alternative production system rather than traditional agriculture. Using thermal energy in greenhouses may produce leafy or other vegetables during sub-zero temperatures in the Trans-Himalayan region, where otherwise, cultivation is not possible. Cultivation in summer is unlikely to be considered a possibility, let alone in winter, but the combination of geothermal energy and new techniques could be realized. Further, prospects include entrepreneurship among the local youths and food and nutritional security. The challenges of food insecurity, mainly during winters, could be met using this free energy, reducing the carbon footprint of transportation (air cargo during winters). Thus, the present study addresses SDG 2 (achieve food security, improve nutrition, and promote sustainable agriculture), 5 (gender equality), 8 (sustainable economic growth), 13 (climate action).
  • Geospatial attributes of Western Himalayan timberline over Himachal Pradesh
    Priyanka Sah, Subrat Sharma
    Handbook of Himalayan Ecosystems and Sustainability Volume 1 Spatio Temporal Monitoring of Forests and Climate, 2022
    The Himalayan region presents the highest timberline in the Northern Hemisphere, which is sensitive to climatological and anthropogenic changes. The mountains of Himalaya rise abruptly, resulting in diversity of landscapes and ecosystems. The present study analyses timberline and topographical influences of mountainous terrain along altitudinal gradient in the Indian Western Himalayan region. Timberline mapping covering the entire state of Himachal Pradesh was done by using satellite image of 30m spatial resolution. Based on their locations, two types of timberline, continuous timberline (CT) and summit enclosing/island-type timberline (SET or ITL) are described. The total length of the timberline in Himachal Pradesh was about 3,257km, of which CT type accounted for 91%, and the remaining was ITL type. The 3,200-3,800m elevation range accounted for 81% of the total timberline length of CT type. In CT type, the mean elevation of timberline segments ranged from 2,491m to 4,081m above mean sea level (asl). The peak distribution of the ITL-type timberline was at a bit lower elevation band than the CT type. Of the total length of the ITL type, about 90% occurred between 3,000 and 3,600m. ITL covered with alpine meadows are a common feature in this part of the Himalayas. However, at a regional scale, climate is an important determinant of timberline, but at a local scale, topography is an obvious way to size up the landscape and influence distribution of tree species. It can be deducted that those complexities of topographic features in the mountains positively influence the distribution of timberline, which may react sensitively to climate warming and anthropogenic changes in different behaviours.

  • Indicator-based vulnerability assessment of forest ecosystem in the Indian Western Himalayas: An analytical hierarchy process integrated approach
    Manoj Kumar, Naveen Kalra, Hukum Singh, Subrat Sharma, Praveen Singh Rawat, Ram Kumar Singh, Ajay Kumar Gupta, Pavan Kumar, N.H. Ravindranath
    Ecological Indicators, 2021
    Understanding the vulnerability of forests and its associated factors is crucial for the sustainable management of forested landscapes. The assessment of vulnerability of forests in the Indian Western Himalayan (IWH) region comprising the states of Jammu & Kashmir (J&K), Himachal Pradesh (HP) and Uttarakhand (UK) was done using six indicators of vulnerability in the form of biological richness index, disturbance index, forest canopy density, fire point intensity and forest extraction intensity of fringe forests. We express this assessment as the “indicator-based vulnerability”. The indicators were allocated weights by multi criteria analysis using analytical hierarchy process. The spatial extent of all of the selected indicators was mapped for the IWH region at a pixel resolution of 24 m and was integrated to find out the vulnerability for each pixel in a GIS environment. The study area was divided into 172 grids of size 0.5°, equivalent to the grid size of available climatic projections, out of which 67 grids were identified as the forest grids. The grids that have at least 5% forest cover were designated as the forest grids and the vulnerability assessment was done only for these grids. The final representation of vulnerability across forested grids of the IWH was done at a spatial resolution of 5' and 0.5° to categorise as low, medium, high and very high class. It was observed that the highest concentration of “very high” and “high” vulnerable grids of 5' size lies in the state of UK, comprising 32 and 31%, respectively. The aggregated values at 0.5° indicate that most of the grids of UK fall under very high vulnerability except for the few uppermost and lowermost grids falling under other categories. In J&K, most of the 5' grids fall under low vulnerability (41%), while medium, high and very high categories are 27, 25 and 7%, respectively. Similarly, out of total 28 grids of size 0.5°, only one grid is categorized as very high vulnerable, while 11 grids fall under high vulnerability. In HP, none of the grids of either size is categorized as very high vulnerable. It was observed that most of the high and very high vulnerable grids in the IWH are in the lower altitudes while higher altitudes have lesser magnitude of vulnerability. Forests occurring at a higher elevation such as the Alpine forests (dry, moist and sub-alpine) is the least vulnerable forests compared to other forest type groups of the IWH.
