Assessing the Impact of Domestic Cattle Influx on Grassland Habitat Using Remote Sensing and Soil Physical Parameters: A Study in Manas National Park

A significant increase in domestic cattle influx within Manas National Park has been linked to substantial soil compaction and degradation of its unique grassland habitat, threatening endangered species dependent on this ecosystem. The study, spanning 21 years (1999–2020), used remote sensing—specifically pixel-based classification of satellite imagery—to track changes in land cover, revealing alarming shifts toward woodland and mosaic habitats due to overgrazing, ecological succession, and human encroachment. Physical soil parameters like bulk density, water content, and porosity were analyzed to assess their impact on vegetation composition. Ground truth data and land-cover definitions enhanced the accuracy of these findings. The research highlights the exponential growth of certain land cover types, underscoring the urgent need for conservation efforts to mitigate threats from climate change, human activities, and ecological processes.
