- Abstract
The microhabitat of sympatric Eastern Blue-tongued Lizard Tiliqua scincoides and Blotched Blue-tongued Lizard T. nigrolutea was recorded along the Yarra River in suburban Melbourne. The habitat within a one metre radius of 20 T. scincoides and more than 23 T. nigrolutea was compared to the habitat available at the study sites. The habitat within one metre of T. nigrolutea was almost all native tussock grasses, under or close to bushes and often under River Red Gums Eucalyptus camaldulensis. The habitat within one metre of T. scincoides was much more varied, including impervious surfaces, gardens and introduced grasses. Disproportionately few Tiliqua spp. were found in floodplain E. camaldulensis without tussock grasses. Individuals of each species were recorded within close proximity of each other. It is plausible that 0.5 ha of grassy woodland might be sufficient to sustain a population of T. nigrolutea. T. nigrolutea appeared to be more common where domestic dogs were prohibited.
