“…Habitat and environmental factors not quantified in this study may have influenced greater glider occupancy both prior to and following the 2009 wildfires. Models of habitat suitability for the greater glider demonstrate a dependence on a range of factors including tree species composition, foliar chemistry, temperature and aridity (Wagner et al 2020;Wagner et al 2021). In our study, the composition of dominant canopy species (DBH ≥40 cm) was relatively consistent, with E. obliqua and E. radiata comprising >80% of the basal area across all sites (Appendix S10).…”

Fire severity has lasting effects on the distribution of arboreal mammals in a resprouting forest

Wildfire severity is assumed to be an important driver of habitat availability and species' distributions in forest ecosystems. Many studies have focused on the immediate or short‐term effects of fire severity in fire‐prone ecosystems, with much less focus on how long the effect of fire severity may persist. We examined the effect of fire severity on the distribution of arboreal mammals at 3 and 10 years post‐fire, in a temperate forest ecosystem dominated by eucalypts that have strong resistance and resilience to low and high severity fire, respectively. The study took place within areas affected by the 2009 Kilmore East‐Murrindindi wildfires in south‐eastern Australia. Sites were established across a gradient of fire severity (unburnt through to canopy consumption) and surveyed at 3 and 10 years following fire. Owing to low detection rates for many species, analyses were limited to greater glider (Petauroides volans) occurrence and arboreal species richness. At both 3 and 10 years post‐fire, the greater glider was restricted to unburnt forest or sites affected only by understorey fire, which acted as fire refugia. Greater gliders were absent from sites affected by high severity, canopy‐consuming fires at both points in time. Greater glider occurrence was associated with high levels of canopy cover (>50%), which were typically those areas that were unburnt or burnt at low severity. The richness of arboreal mammals increased over time and was greater in unburnt or minimally affected forest. Our findings emphasize: (i) that fire severity is an important driver of the distribution of arboreal mammals; and (ii) the importance of recognizing longer‐term effects of fire severity in assessing species distributions, even in highly resilient forest communities. Recent advances in mapping fire severity provide new opportunities to assess the effects of fire severity on the distributional patterns of fauna in eucalypt forests.

“…While an increase in home range size due to forage quality has to date not been studied and represents a critical knowledge gap, greater gliders have been observed to increase their home range size due to sparse nesting resources (Pope et al, 2004 ; Smith et al, 2007 ; Wagner et al, 2021 ). We would expect a lower likelihood of detection when using a standardized survey method for a range of forest structures and configurations of feeding habitat or nesting resources.…”

“…The SGG is listed as 'Endangered' federally under the EPBC Act and the Victorian Advisory List of Threatened Vertebrate Fauna (see Department of Environment, Land, Water and Planning 2019). Clearing, intense fire, logging and fragmentation are the major threats to the SGG (Tyndale-Biscoe and Smith 1969; Kavanagh and Webb 1998;Kavanagh 2000;McCarthy and Lindenmayer 2006;McLean et al 2018;Wagner et al 2021;Lefoe et al 2022).

“…Lindenmayer and Burnett 2021) exacerbates these problems. Recently, extreme droughts and higher temperatures (including overnight temperatures) associated with global warming have been demonstrated as emerging threats (Youngentob et al 2011;Smith and Smith 2018;Wagner et al 2021). This may result in reduction in quality or availability of food and increased morbidity or mortality due to heat stress.…”

Context. The tall forests of Victoria, Australia, which are available for logging, are foreshadowed to be converted from mature forest to hostile environments for mature-forest dependent species by 2030. This has occurred within a 60-year time-frame since the advent of industrial-scale logging in the region. In this light, Protection Areas (PAs) of approximately 100 ha have been implemented to protect habitat with high density populations of Yellow-bellied Gliders (Petaurus australis) and Southern Greater Gliders (Petauroides volans). Aims and methods. Ten considerations are provided to guide location and design of PAs, and to provide set asides and other forms of protection for mature-forest dependent species in the context of the temporal and spatial scale of logging activity. Key results. Considerations are grouped into Overall approach (precautionary), Survey records and habitat attributes (occurrence, habitat, vegetation types), Size and shape considerations (edge and fragmentation effects); Management history (logging and fire), and Boundary considerations (context and conditions). In addition, set asides encompassing home ranges; and high levels of basal area retention, are also required in the remainder of planned logging coupes. Conclusions. Addressing these considerations in PAs, in set asides and in retention will provide some protection for mature-forest dependent species, but will be insufficient without ecologically sustainable forest management at the coupe level, for the sustained yield of all habitat components of these forests. Implications. The conservation of mature-forest dependent species in the context of an ongoing timber industry requires logging return times well beyond current expectations, resulting in a substantial reduction in resource commitment to industry.
