Abstract
Knowledge of site-specific ecological factors affecting a species’ resource selection is essential to assist in habitat management for a species’ conservation, particularly for species with narrow resource width. This study aimed to assess whether microhabitat variables affect the selection of Eucalyptus resinifera sap feed trees by yellow-bellied gliders (Petaurus australis) in north-eastern Australia. Microhabitat variables were measured in a simplified way around glider-selected and -non-selected Eucalyptus resinifera trees. Canopy cover and percentage of burnt trunk below breast height were identified as influential on feed tree selection, with feed trees showing a higher percentage of burnt trunk and a lower surrounding canopy cover. While the direct effect of fire on a potential feed tree remains to be clarified, fire may affect the structural composition of vegetation leading to lower surrounding canopy cover around potential feed trees. Thus, any forest management, such as logging and grazing should be practiced with great caution since they affect structural features of the vegetation that may contribute to the selection of feed trees by this species and may also affect its alternative food resources.
