Flying fox species vary in body weight, ranging from 120–1,600 g (0.26–3.53 lb). Pam Tully’s bat hospital ( left ) has become the center of all spectacled flying fox rescue efforts during the tick season. Spectacled flying foxes (SFF) were originally listed as vulnerable in 2002 and up-listed to endangered in 2019 with population data supplied by CSIRO. Population modelling suggests that the decrease in the spectacled flying-fox population was driven by the long-term effects of severe cyclones. Spectacled flying foxes are the main species we care for at the Bat Hospital. But habitat destruction and harassment largely caused the species' population to drop from 250,000 in … Up to 8,000 spectacled flying-foxes, around 12% of the species' population, will be forced to leave their home in central Cairns. Proc. The spectacled flying fox (Pteropus conspicillatus) is listed as vulnerable to extinction in Australia. Spectacled flying fox Conservation (more information at Conservation of Australian Flying Foxes) Bat conservation is a key aspect of our work at Tolga Bat Hospital. A survey of all known Spectacled Flying Fox camps in the wet tropics was undertaken in March 1998 with the assistance of volunteers. Also, the health of roost trees at the library site, and therefore the viability of the site as a spectacled flying fox roost, is diminishing. The species' restricted population is in decline, putatively attributed to decreasing habitat, climatic extremes, anthropogenic activities, and more recently, mass mortality events associated with tick paralysis and neonatal cleft palate syndrome. Data collection . al. Heat stress events, urban development and increased construction in close proximity to the Cairns City Library colony will only continue to stress and adversely affect the flying fox population.

The large flying fox has the longest forearm length and reported wingspan of any species, but some species exceed it in weight. In 2014, Cairns Council was found guilty, under the Queensland Nature Conservation Act, of driving away spectacled flying-foxes and illegally pruning the habitat trees they roosted in. Also, the health of roost trees at the library site, and therefore the viability of the site as a spectacled flying fox … 1849:109-112. c. to present an inclusive understanding of Spectacled Flying-fox population dynamics. The Grey headed is listed as Vulnerable to extinction, while the Spectacled is listed as Endangered under the Environmental Protection and Biodiversity Conservation Act 1999. Here, I present a review of current knowledge on the Spectacled flying-fox, and a description of my PhD project and a summary of the results (Fox 2006). Its wingspan is up to 1.5 m (4 ft 11 in), and it can weigh up to 1.1 kg (2 1 ⁄ 2 lb). The spectacled flying-fox has shown a decline from a population of 214,750 in November of 2005 to 92,880 in November of 2014. Camps were assigned to three categories (urban, peri-urban and non-urban) depending on their distance from urban areas – defined as human habitation. Flying-fox population counts During the study period SFF population counts were conducted by several different groups using two different monitoring methodologies: camp fly-out counts and day counts of roosting SFF. Further struggles for the spectacled flying-fox. A survey of all known Spectacled Flying Fox camps in the wet tropics was undertaken in March 1998 with the assistance of volunteers. Statistics from Richards and Hall (2000, p2) indicate that the genus Pteropus to which the spectacled flying fox belong form a population of 65 species worldwide. Spectacled flying foxes live in colonies in rainforests, mangroves, paper bark and eucalyptus forests. Most come in as as result of tick paralysis, some from entanglement on barbed wire fences, and a few from entanglement in netting over backyard fruit trees. Review of Current Knowledge The Spectacled Flying-fox is a large fruit bat so named for The spectacled flying fox (Pteropus conspicillatus) is a difficult species to manage due to its dual status as an agricultural pest and a native species under threat. Heat stress events, urban development and increased construction in close proximity to the Cairns City Library colony will only continue to stress and adversely affect the flying fox population. Lond. 2018) which represents a … Also, the health of roost trees at the library site, and therefore the viability of the site as a spectacled flying fox roost, is diminishing. A recent spectacled flying-fox monitoring report was published by the National Environmental Research Program which illustrates that the population has decreased 4-6% annually over the past decade. disperse and permanently relocate a nationally important population of Spectacled Flying-fox (Pteropus conspicillatus) located at 151 Abbott Street, Cairns, Queensland (see EPBC Act referral 2019/8424).
