Abstract : The natural profile of species diversity at habitat level & biodiversity at biospheric level always displays temporal & spatial variation in time and space, hence is a dynamic function. Therefore it is mandatory for researcher to undertake spatial (geographical) and temporal (time specific) mapping of the species diversity to investigate the degree of variation. The present article being the part of continuous mapping of lizard faunal diversity of Madhepura urban conglomerates done during the years 2014-2016 targets to unravel the spatial variation of garden lizards found in two different habitats – home garden and mangrove. Oriental garden lizards being an important member of lacertilian reptiles are subjected to population wise threat & endangerment due to multidimensional unmindful anthropogenic interference. The article brings on record different species of garden lizards present in specific terrestrial habitats such as home garden & mangroves of Madhepura. Six different species have been identified from these habitats & their cumulative species diversity index through Shannon-Weiner equation (S-W) have been statistically computed on the basis of species abundance & richness recorded numerically during the sampling without sacrificing any live individual (IBML) so that none of the species get harm during the research.
