Summary: Extreme fire events have increased in south-eastern Australia due to human-induced climate change. Fuel reduction burning is commonly used to reduce wildfires, but its effectiveness under extreme climatic conditions is limited. This study examines the extent of fuel treatment in planned burns across different fire management zones and the impact of fuel reduction burning on wildfire severity. The results show that fuel reduction burn coverage is often lower than desired targets in zones focused on asset protection, but within the desired range in zones targeting ecological objectives. At the point scale, fuel reduction burning moderates wildfire severity for several years in shrubland and forests. Fuel availability plays a significant role in limiting fire occurrence and severity in the first 18 months after fuel reduction burning, while fire weather becomes the dominant driver of high severity fires after 3-5 years. At a local landscape scale, the extent of high canopy scorch decreases as the extent of recently treated fuels increases. However, there is a high level of uncertainty regarding the effect of recent fuel treatment. Overall, recent fuel reduction burning can aid in wildfire suppression near assets, but its impact at larger scales is highly variable.

Summary: The aim of this study was to identify the environmental drivers of interannual variation in wildfire extent and severity in south-eastern Australia. The results showed that climatic potential for large and severe forest fires has increased since the 1950s, likely due to anthropogenic climate change. The magnitude and severity of the 2019-2020 fires reflected extreme climatic conditions, indicating the increasing size and severity of wildfires.

Summary: Wildfires are creating large high-severity patches far from undisturbed habitats, impacting bird communities. Community richness decreases with distance and patch size, while increasing with years since fire. Large high-severity patch interiors contain subsets, rather than complements, of edge communities, leading to shifts in avian diversity and community composition.

Summary: The use of genetic information for conservation biology has become more widespread, including for invasive species management. Despite the threat posed by red foxes to Australian fauna and agriculture, few studies have investigated the population genetics of foxes in Australia. A recent study in New South Wales found moderate genetic diversity with low to moderate levels of inbreeding and limited evidence of population genetic structure among foxes sampled.

Summary: Live tree basal area and mean annual precipitation were found to be influential predictors of dead standing trees (DST) and coarse woody debris (CWD) biomass, with fire history also playing a significant role in predicting changes in dead wood abundance over time. The study suggests that forest productivity, fire history, drought, and wood density are important determinants of dead wood dynamics, and could potentially be influenced by altered fire regimes and changing climate.

Summary: Protected areas and wildlife reintroductions are effective conservation measures, but they can lead to unexpected species-specific responses. A study in South Africa found species-specific responses to reserve expansion, with generally positive but unsustained responses in occupancy and intensity of use. Managed herbivores and the apex predator exhibited sustained or delayed positive responses, while subordinate predators and unmanaged herbivores had short-lived or neutral responses. The interactive effects of top-down suppression, competitive pressure, and increased resources contributed to the variable responses. Monitoring the entire wildlife community is crucial for implementing successful conservation actions.

Summary: The unprecedented bushfires in southeastern Australia in the summer of 2019/20 drew attention to the role of forest management in influencing fire risks and impacts. Despite arguments that timber harvesting worsened the severity of the fires, the evidence does not support this claim. Analysis of the fires revealed that factors such as below-average rainfall, extreme fire weather conditions, and local topography were the primary contributors to the extent and severity of the fires, not past timber harvesting practices. Policy proposals to mitigate fire risks should be evidence-based and incorporate various perspectives, including Indigenous knowledge and experiences from local fire managers, to enhance forest resilience and community safety.

Summary: Deer are critical components of many ecosystems, and accurately estimating deer abundance and density is crucial for understanding their roles. This study systematically reviewed journal articles published from 2004 to 2018 to evaluate trends in study objectives, methodologies, and abundance and density estimates, as well as their variations with biophysical and anthropogenic attributes. The findings highlight the need for reporting methodological details, robustly assessing bias, reporting precision, using methods that increase detection probability, and staying up to date on new methods to improve the usefulness of deer abundance and density estimates.

Summary: The aim of this study was to investigate the population structure of rusa deer in the Illawarra region of New South Wales and determine the effects of landscape features on gene flow. The results showed that genetic diversity was highest near the original introduction site, and a railway line restricted gene flow. Surprisingly, the Illawarra escarpment did not limit gene flow, and there was no evidence of sex-biased dispersal.
