Habitat loss for black flying foxes and implications for Hendra virus.

Context: Environmental change impacts natural ecosystems and wildlife populations. In Australia, native forests have been heavily cleared and the local emergence of Hendra virus (HeV) has been linked to land-use change, winter habitat loss, and changing bat behavior. Objectives: We quantified changes in landscape factors for black flying foxes ( Methods: We measured the spatiotemporal change in human population size and native 'remnant' woody vegetation extent. We assessed changes in the observed Results: Human populations in these bioregions grew by 1.18 M people, mostly within 50 km foraging areas around roosts. Remnant forest extent decreased overall, but regrowth was observed when policy restricted vegetation clearing. Winter habitats were continuously lost across all spatial scales. Observed roost counts of Conclusion: Native remnant forest loss and winter habitat loss were not directly linked to spatial human population growth. Rather, most remnant vegetation was cleared for indirect human use. We observed forest loss and regrowth in response to state land clearing policies. Expanded flying fox population surveys will help better understand how land-use change has impacted Supplementary Information: The online version contains supplementary material available at 10.1007/s10980-023-01642-w.
