Biodiversity can benefit from fires tailored to suit particular ecosystems and species
Abstract Background ‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous. Approach We sought resolve ambiguity surrounding ‘megafire’ by conducting a structured review use and definition term several languages peer‐reviewed scientific literature. collated definitions descriptions megafire identified criteria frequently invoked define megafire. recorded size location megafires...
Summary 1. Managing fire to achieve hazard reduction while providing for biodiversity conservation is complex in fire‐prone regions. This challenge exacerbated by limited understanding of post‐fire changes habitat and fuel attributes over time‐scales commensurate with their development, a paucity empirical research integrating the effects on these attributes. 2. We used 110‐year chronosequence investigate temporal development resources fauna, fuels semi‐arid Mallee vegetation, south‐eastern...
Abstract Aim A common strategy for conserving biodiversity in fire‐prone environments is to maintain a diversity of post‐fire age classes at the landscape scale, under assumption that ‘pyrodiversity begets biodiversity’. Another extensive areas particular seral state regarded as vital persistence threatened species, this will also cater habitat needs other species. We investigated likely effects these strategies on bird assemblages tree mallee vegetation, characterized by multi‐stemmed...
Fire is used as a management tool for biodiversity conservation worldwide. A common objective to avoid population extinctions due inappropriate fire regimes. However, in many ecosystems, it unclear what mix of histories will achieve this goal. We determined the optimal history given area biological with method that links tools from 3 fields research: species distribution modeling, composite indices biodiversity, and decision science. based our case study on extensive field surveys birds,...
Fire is both a widespread natural disturbance that affects the distribution of species and tool can be used to manage habitats for species. Knowledge temporal changes in occurrence after fire essential conservation management fire-prone environments. Two key issues are: whether postfire responses are idiosyncratic or if multiple show limited number similar responses; such time since predict across broad spatial scales. We examined response bird semiarid shrubland southeastern Australia using...
Summary 1. Fire is a major driver of ecosystem structure and function worldwide. It also widely used as management tool to achieve conservation goals. A common objective the maintenance ‘fire mosaics’ comprising spatially heterogeneous patches differing fire history. However, it unclear what properties mosaics most enhance efforts. Here we focus on spatial temporal fire‐prone landscapes that influence distribution small mammals. 2. We surveyed mammals in 28 (each 12·6 km²) representing range...
ABSTRACT Biodiversity faces many threats and these can interact to produce outcomes that may not be predicted by considering their effects in isolation. Habitat loss fragmentation (hereafter ‘fragmentation’) altered fire regimes are important biodiversity, but interactions have been systematically evaluated across the globe. In this comprehensive synthesis, including 162 papers which provided 274 cases, we offer a framework for understanding how interacts with fragmentation. Fire three main...
Abstract Aim Fire affects the structure and dynamics of ecosystems world‐wide, over long time periods (decades centuries) at large spatial scales (landscapes regions). A pressing challenge for ecologists is to develop models that explain predict faunal responses fire broad temporal scales. We used a 105‐year post‐fire chronosequence investigate small mammal across an extensive area ‘tree mallee’ (i.e. vegetation characterized by multi‐stemmed eucalypts). Location The Murray Mallee region...
ABSTRACT Aim We examined the century‐long post‐fire responses of reptiles to (1) determine time‐scales over which fauna – fire relationships occur, (2) assess capacity a conceptual model predict faunal response fire, and (3) investigate degree models can species occurrence are transferable across space. Location A 104,000 km 2 area in semi‐arid Murray Mallee region south‐eastern Australia. Methods surveyed at 280 sites chronosequence. developed generalized additive mixed (GAMMs) relationship...
A capacity to predict the effects of fire on biota is critical for conservation in fire‐prone regions as it assists managers anticipate outcomes different approaches management. The task complicated because species’ responses can vary geographically. This poses challenges, both conceptual understanding post‐fire succession and We examine two hypotheses why species may display geographically varying fire. 1) Species’ are driven by vegetation structure, but – relationships spatially (the...
Fire influences the distribution of fauna in terrestrial biomes throughout world. Use fire to achieve a mosaic vegetation different stages succession after burning (i.e., patch-mosaic burning) is dominant conservation practice many regions. Despite this, knowledge how spatial attributes mosaics created by affect extremely scarce, and it unclear what kind land managers should aim achieve. We selected 28 landscapes (each 12.6 km(2) ) that varied extent diversity 104,000 area semiarid region...

Abstract Aim A common assumption in fire ecology and management is that landscapes with a greater diversity of fire‐ages will support animal species (i.e. ‘pyrodiversity begets biodiversity’). This based on the idea more diverse history provide array post‐fire habitats, leading to number within landscape. We assessed hypothesis pyrodiversity biodiversity by enhancing community differentiation (β diversity), resulting increased landscape‐scale richness (γ‐diversity). used reptiles as...
Abstract Fire can promote biodiversity, but changing patterns of fire threaten species worldwide. While scientific literature often describes ‘‘inappropriate regimes’’ as a significant threat to less attention has been paid the characteristics that make regime inappropriate. We go beyond this generic description and synthesize how inappropriate regimes contribute declines animal populations using threatened mammals case study. developed demographic framework for classifying mechanisms by...
Fire is an integral part of the Earth System and humans have skillfully used fire for millennia. Yet human activities are scaling up reinforcing each other in ways that reshaping patterns across planet. We review these changes using concept regime, which describes timing, location, type fires. then explore consequences regime on biological, chemical, physical processes sustain life Earth. Anthropogenic drivers such as climate change, land use, invasive species shifting regimes creating...
Fire influences plant survival, reproduction, and establishment. Consequently, plants exhibit fire-related traits. Grouping species with similar traits into Plant Functional Types (PFTs) enables predictions of fire–related change based on ecological mechanisms. However, if PFTs are to advance conservation decision-making, we must know robust. We developed a PFT approach predict how relative abundance changes as function time since fire, tested empirically. First, used trait databases...
A critical requirement in the ecological management of fire is knowledge age-class distribution vegetation. Such important because it underpins features to plants and animals including retreat sites, food sources foraging microhabitats. However, many regions, vegetation severely constrained by limited data available on history. Much fire-history mapping restricted post-1972 fires, following satellite imagery becoming widely available. To investigate history semi-arid Murray Mallee region...
Abstract Predicting the response of faunal communities to fire presents a challenge for land managers worldwide because post‐fire responses species may vary between locations and events. Post‐fire recovery can occur via nucleated from in situ surviving populations or by colonization ex populations. Fine‐scale spatial patterns patchiness fires proximity burnt sites source contribute both variability processes which recover. We examined avifauna at recently within extensive semi‐arid...
