Abstract:
Parks and gardens, particularly botanical gard-ens with a high diversity of species, provide a storehouse of genetic resources from within the region and they also provide food and pharmacological resources for a range of species such as birds, mammals, reptiles and insects the higher the diversity of species in parks the higher the potential to perform these functions. In the present study Quick Bird imagery of 2005 is used for comparative assessment of NDVI and TNDVI indices with superwised classified imagery of LalBagh, one of the largest and oldest botanical Garden in the Bengaluru. Lalbagh started in 1760 was given the status of a Government Botanical Garden in 1856 and since then it has been an internationally renowned centre for scientific study of plants and botanical artwork and also conservation of plants. The NDVI and TNDVI transformed imagery of Lalbagh showed variation in their values. The different land use classes of supervised classified imagery showed more resemblances to the NDVI than TNDVI. It was observed that 33% of lalbagh’s 240 acres is covered with thick canopy comprising mainly large mature trees. Small statured ornamental specimens and many small trees growings in thickets like groupings constituting Thin canopy covered 20% area. Water Constitute about 13%. Rocky area is present on the North West comprises about 12% and Grass area about 16.6%. This study gives various land uses of the entire lalbagh in a broader picture and more supplementary study is needed to give tree wise distribution in the entire lalbagh.
