The study was conducted over a period of one month concentrated Dhanmondi Lake, Dhanmondi, Dhaka.The study also focused on impact on development works and edge effect to the floral diversity & micro climate in Dhanmondi Lake. The duration of the sunlight almost 14 hours daylight during the study period and there was little variation in temperature near and 10meter distance from path ways.  Only 0.7 (º C) differences were observed at 10cm below the ground inside the lake. Quadrats that were away from the path had a higher DS value demonstrating lower floral diversity compared to that of the quadrats near the path. Results revealed that the Ds value near to pathway was 0.2608 and 0.7481 for 10 meter distance for all species from the pathway.
