As urban areas continue to expand and replace tural and agricultural landscapes, the ability to mage and conserve tive wildlife within urban environments is becoming increasingly important. To do so we first need to understand species' responses to local-level habitat attributes in order to inform the decision-making process and on-ground conservation actions. Patterns in the occurrence of tive terrestrial reptile and small mammal species in 59 sites located in remnt urban habitat fragments of Brisbane City were assessed against local-level environmental characteristics of each site. Cluster alysis, multidimensiol scaling ordition, and principal axis correlation were used to investigate relationships between species' occurrences and environmental characteristics. tive reptiles were most strongly associated with the presence of termite mounds, a high amount of fallen woody material, and a moderate amount of weed cover. tive small mammals were most strongly associated with the presence of grass trees (Xanthorrhoea spp.), and both reptiles and small mammals were negatively influenced by increased soil compaction. Significant floristic characteristics were considered to be important as structural, rather than compositiol, habitat elements. Therefore, habitat structure, rather than vegetation composition, appears to be most important for determining tive, terrestrial reptile and small mammal species assemblages in urban forest fragments. We discuss the magement implications in relation to human disturbances and local-level magement of urban remnts.
