Floristic Diversity, Community Composition and Structure in Nanda Devi National Park After Prohibition of Human Activities, Western Himalaya, India

A ban on human activities in Nanda Devi National Park since 1983 has led to significant positive changes in plant diversity, forest composition, and ecological conditions. The study documented 409 plant taxa across 71 families, with dominant forests comprising Betula utilis along the timberline and mixed Abies spectabilis-B. utilis communities. Alpine meadows like Dibrugheta exhibited the highest species richness (128 taxa). Population structure analysis revealed variations in seedling, sapling, and tree layers across different communities. Comparison with earlier studies from 1993 and 2003 highlights the ecological recovery post-prohibition, providing a baseline for future assessments and informing conservation strategies within UNESCO World Heritage Sites.
