.... honeybees impact on indigenous species in two broad ways, firstly via competition for tree hollows, and secondly via competition for floral resources.
....
Threatened species which are likely to be affected by competition from honeybees for hollows include the Brush-tailed Phascogale, Phascogale tapoatafa; Squirrel Glider, Petaurus norfolcensis; Yellow-bellied Glider, Petaurus australis; Major Mitchell's ****atoo, Cacatua leadbeateri; Glossy Black ****atoo, Calyptorhynchus lathami; Superb Parrot, Polytelis swainsonii; and Regent Parrot, Polytelis anthopeplus. Populations of protected species that may become threatened include the Common Brushtail Possum, Trichosurus vulpecula; Greater Glider Petauroides volans; and Sugar Glider, Petaurus breviceps (Garnett 1992, Oldroyd et al. 1994, Paton 1996, Soderquist et al. 1996, Trainor 1995, Wood and Wallis 1998, Pyke 1999, Soderquist 1999).
I have seen feral honey bee's impact in bushland first hand. So don't feel bad about controlling feral animals. Endangered Australian native flora and fauna species will be thanking you. :hug:
