Phenology is the study of periodically recurring patterns of growth and development of plants and animal behavior during the year. Vegetation phenology is the study of recurring patterns of plant growth and development, for example, the time of (a) budburst, (b) plant flowering, (c) leaf green up, and (d) senescence. The present study employed a Moderate Resolution Imaging Spectroradiometer (MODIS) based Enhanced Vegetation Index (EVI) dataset to track vegetation phenological trends in response to climate change activity over the Eastern Himalayan in India during 2000–2024. The vegetation phenological parameters such as Start of Season (SOS), End of Season (EOS), and Length of Season (LOS) will be calculated from the vegetation Enhanced Vegetation Index (EVI). The overall study will be conducted on the cloud-based Google Earth engine platform. The present study investigates the effect of temperature, and precipitation on the start of the season (SOS) and end of the season (EOS), in major vegetation of the study area and their long-term trends. The study can provide definite evidence for global climate change and the natural environment. Phenology is an aspect of biodiversity conservation, and studying patterns and their influencing factors can help achieve the goals of SDG 15. It will report on adaptation strategies and best practices for mitigating the impact of climate change on Himalayan vegetation.
