Study on the Habitat of Lizards on the Small Scale Green Space in Urban Area

Abstract

We discussed the status of the lizards (Plestiodon japonicas and Takydromus tachydromoides) as an indicator of the habitat of small animals in urban areas. The lizards were recorded by visual encounter surveys at 13 investigation sites of green spaces in Fujisawa, Kanagawa Prefecture from May to October in 2007, and there qualities of habitat were evaluated. The encounter frequency was calculated, it was very high at the home gardens. The analysis of the regulation factor for population density, it showed the significance that P. japonicus was correlated to the area rates of the porosity structure on the surface and the percentage of green spaces in surrounding on the each investigation sites.
