NAYANA (senior) AREKERE LAKE AREA 1 : AREKERE LAKE Arekere lake was originally spread over an area of approximately 37 acres, the lake is bounded on the west by Bannerghatta road, on the north by BDA Eighty Feet Road, on the east by Shantinikethan Layout and on the south by Hulimavu Main Road. According to the BBMP , the perimeter of the lake is about three kilometers. It was possibly a manmade water reservoir created approximately 100 years ago. The lake is under the jurisdiction of the BDA. As is the case with many other lakes in Bangalore, in the last two decades the Arekere Lake has been encroached upon by real estate developers, and the current extent of the lake according to our observation has been estimated to be only 23.2 acres .
AREA 2 : MINI FOREST Mini forest is in JP Nagar, 3rd phase, which is a forest in the middle of a concrete jungle. The park is well maintained and kept clean by the BBMP and also some of the locals who use the park as a nice get away from their daily activities. According to our recent observations, the park is being dumped with garbage at various places. MAPPING OF BOTH AREAS

•COMMON NAME : GULMOHAR •SCIENTIFIC NAME : Delonix regia •SPECIES: Flowering plant in the bean family Fabaceae •ENDEMIC TO: Madagascar’s dry deciduous forests but has been introduced into tropical and sub-tropical regions worldwide • HEIGHT OF THE TREE: 39.93 feet / 1217.3cms •GIRTH OF THE TREE: 5.83 feet / 178cm •DESCRIPTION : The leaves as well as the flowers are large. The leaves are fern like. The trunk is large and stems are woody throughout. 4 petals are orange-red, almost scarlet and 1 is whitish inside with red spots, longer and narrower than the others. Plant chosen to calculate the release of oxygen: area of 1 leaf = 42cm2 ml of O2 produced per hour = 42*1.2 = 50.4ml the plant has 120 leaves so, ml of oxygen produced by the plant in 1 hour= 6048ml so, in one day it produces = 6048*12= 72,576ml approx • COMMON NAME : SACRED TREE , FLAME OF THE FOREST • SCIENTIFIC NAME : Butea monosperma • SPECIES: Butea, Flowering plant. • ENDEMIC TO: Tropical and sub- tropical parts of Indian Subcontinent and Southeast Asia. • HEIGHT OF THE TREE: 79 feet / 2407.92 cm • GIRTH OF THE TREE: 8.8331 feet / 265 cm • DESCRIPTION : Medium-sized dry- deciduous tree. Slow growing trees, have a low growth rate of a few feet per year. Leaves are pinnate with a petiole and three leaflets. Flowers are long, bright orange-red. Fruit is a pod. Plant chosen to calculate the release of oxygen: area of 1 leaf = 20 cm2 ml of O2 produced per hour = 20*1.2 = 24 ml the plant has 61 leaves so, ml of oxygen produced by the plant in 1 hour= 1464 ml so, in one day it produces = 1464*12 = 17,568 ml approx

WATER CONSERVATION We have made provisions for rain water harvesting. GREEN LIFESTYLE We have a huge garden with lots of trees, plants and many birds and butterflies. We have Solar panels installed on the terraces of our buildings WASTE MANAGEMENT We segregate paper waste, kitchen(dry)waste, plastic waste and electronic waste We have a vermi compost pit in our garden so as to decompose the biodegradable waste. We have installed incinerator for sanitary wastes.
