- Abstract
Botanical gardens dedicate their resources to the research and preservation of plants as well as educating the public about the diversity of plant species found across the world. As a result, this study was conducted to determine the tree composition and diversity of the Mahatma Gandhi Botanical Garden, GKVK, Bengaluru. The garden was divided into ten parts with an area of 26 hectares. The trees with girth size of at least thirty centimetres were considered for enumeration, after enumeration it was observed that there were 2140 trees from 186 different species; twelve of these are naturalized forest tree species, while the remaining 174 are planted species. The tree diversity was found to be highest in block 1 and lowest in block 2, where the number of tree species was found to be 83 and 34, respectively in block 1 and 2. Importance Value Index (IVI) was found highest for Millettia pinnata (25.71), Azadirachta indica (25.17) and Albizia lebbeck (16.59), where these three tree species comprise around 27.73 per cent of the total tree population. The highest tree population was found in the girth class 30-60 cm, followed by 60-90 cm, where combinedly they account for sixty per cent of total tree population. The majority of the trees fall under height classes 6-9 m, 9-12 m and 12-15 m, where they account for 61.5 per cent of total tree population. It was found that trees in botanical gardens belong to 49 families, where the highest tree population was found in the Fabaceae family, which was followed by Meliaceae and Myrtaceae. The overall results revealed that the botanical garden is rich in tree species composition and diversity.
