Unveiling the Ecological Tapestry: Alpha Diversity Patterns in the Banas River Corridor, Gujarat, India

Abstract

Alpha diversity, also known as α-diversity, refers to the diversity of species within a specific area, community, or ecosystem. In this study, an analysis of alpha diversity in the Banas River corridor of Gujarat was conducted using the quadrate sampling method. The flora of the Banas River corridor in Gujarat demonstrates moderate levels of species diversity, evenness, and richness, indicating a vibrant and diverse ecosystem. Total 133 tree and Shrub species were observed from area. The Shannon diversity index, which measures the variety of plant species present, yielded a value of 2.26. This indicates a reasonable level of species diversity within the area. The Simpson diversity index, which assesses the distribution of individuals among species, resulted in a value of 0.88, suggesting a balanced distribution and promoting a healthy ecosystem. Additionally, the evenness value of 0.92 indicates an equitable representation of species, ensuring that no single species dominates the flora and allowing for the coexistence of multiple species. The Menhinick index, which measures species richness, provided a value of 2.16, indicating a moderate level of species richness in the Banas River corridor. This suggests that the area is home to a diverse range of plant species. Overall, the data from the alpha diversity analysis highlights a diverse and stable ecosystem in the Banas River corridor, characterized by a vibrant mix of plant species. This diversity promotes ecological resilience and the coexistence of different species, contributing to the overall health and functioning of the ecosystem.
