![]() ![]() When koalas in urban areas are moving around their home range, or travelling through new areas during dispersal and breeding season, backyards can pose a serious threat. Even friendly and curious dogs can unintentionally harm a koala through play or stressing the koala. It's also common in areas with a higher density of dog ownership and the risk to koalas increases if there is more than one dog in a yard.ĭog attacks occur with healthy koalas as much as sick ones. These deaths are usually caused by domestic dogs, generally in suburban backyards.Īttacks are more likely to happen during July to September, at the peak of breeding season when koalas are moving around more. It’s also more common during breeding and dispersal season (July to December) when koalas are moving around more.ĭog attacks have historically been the third most significant impact on koalas. This movement usually happens at night, but koalas can be active at any time. Although koalas spend most of their time in trees, they need to move between trees within their home range. Vehiclesĭeath or injury from being hit by a moving vehicle is the second most significant threat to koalas. bushland degradation from poor management, fire, or pest and weed infestations.įragmentation happens when development creates barriers to movement, including the loss of stepping stone trees in the urban landscape. Habitat loss and fragmentation affect the genetics of koala populations by reducing genetic variation and gene flow.broad-scale clearing in rural and peri-urban areas.This can lead to population decline.įor more information on sick or injured koalas download the fact sheet - how to spot an sick or injured koala. High levels of infertility have been found in many koala populations, with levels of more than 50% previously recorded in Queensland. koala retrovirus (KoRV) – an immunodeficiency that can be genetically transmitted between koalas and from parent to offspring.chlamydiosis – symptoms include reduced fertility rates, blindness and ultimately death.Several diseases are a threat to the resilience of koala populations. The main threats to koalas include habitat loss and fragmentation, road mortality, dog attacks, disease, backyards and climate change. The largest declines occurred in bushland areas, as a flow-on effect from habitat loss and mortality in urban areas. A survey in 2008 showed an estimated 64 per cent decline in koala populations throughout this coastal region.Ī follow-up study in 2015 showed an estimated 80 per cent decline in koala populations between 19. The Queensland Government first began monitoring Koala Coast koala populations in 1996. Redlands Coast is part of the wider South East Queensland Koala Coast. ![]()
