The article describes a study conducted by naturalists from Pune, India, in collaboration with an NGO called RANWA. The study aims to assess the biodiversity and environmental changes in the Pune urban area. The researchers standardized the methodology and focused on living organisms as indicators of ecosystem health. They classified habitat types into wilderness zones (forests, scrub, grasslands) and impacted zones (plantations, agriculture, habitations). The study area extends approximately 30 km from the City Post office and includes Pune and Pimpri-Chinchwad Municipal Corporations. The results show varying diversity levels across organismic groups and habitat types, with some species being sensitive to human impact while others are more tolerant. The study also highlights ongoing changes in the landscape, including habitat destruction due to urban expansion and infrastructure development. The researchers emphasize the importance of ecological monitoring and restoration efforts and hope that their study will contribute to generating scientific data for environmental protection.
