Wildfires are prevalent across Australian landscapes and their effects on plants are highly variable. Climate change has already caused an extensive fire season in 2019-20 in eastern Australia and frequency and intensity of fires is predicted to further increase into the future. These dynamic changes in the fire regime places plant species, even those with fire-adapted traits, at risk of population decline or extinction. A fundamental aspect of fire-plant relationships is understanding the plant-responses and processes that cause change when related to fire. This hinges on the species, size and age specifics of individual plants. Plants can be broadly categorised as resprouters or seeders. Resprouters are able to survive fire through resprouting new shoots, while seeder species are typically more sensitive to fire and persist through recruitment. However, time between fire events must be sufficient to allow these species to reach reproductive maturity. Thus, it is critical to highlight
Context: Fire severity and frequency is predicted to increase over the remainder of the 21st century in Australia's temperate forests; therefore, the effects of fire severity on forest-dependant species is of major conservation concern. Aims: Determining the short-term (<1 >year) effect of fire severity on a forest-dependant species, the greater glider, Petauroides volans, in Monga National Park, south-eastern New South Wales. Methods: Three fire-severity classes were investigated, namely, low (canopy unburnt), moderate (partial canopy burn) and high (complete canopy consumption). Fifteen randomly allocated sites were visited in total, with five sites in each fire-severity class being visited on three separate occasions. Spotlighting of two off-track transects per site was completed over a 4-week period by using multi-covariate distance sampling (MCDS) to estimate greater glider densities at each fire-severity class. Key results: An overall mean greater glider density estima
Ground dwelling mammal communities are documented six months before and after the Clyde Mountain Wildfire of 2019/2020 in Monga National Park. Across eight sites before fire, approximately 12 ground dwelling mammal species were recorded. Survey effort post-fire increased to 40 sites, spanning three fire severity classes (low, moderate and extreme), revealed 16 ground dwelling mammal species. Species consist of small, medium and large native (one threatened species) and introduced mammals, though consistent with previous findings of ground dwelling mammal diversity in the area. Overall a greater number of species were found in low, compared to moderate and severe fire severity classes. Recovery and detection of mammals occurred in a shorter time period, again, in sites that experienced low, followed by moderate and extreme fire severity.
