Abstract Accurate ground‐based estimation of the carbon stored in terrestrial ecosystems is critical to quantifying global budget. Allometric models provide cost‐effective methods for biomass prediction. But do such vary with ecoregion or plant functional type? We compiled 15 054 measurements individual tree shrub from across Australia examine generality allometric above‐ground This provided a robust case study because includes ecoregions ranging arid shrublands tropical rainforests, and has...
Abstract Question Frequent severe wildfires have the potential to alter structure and composition of forests in temperate biomes. While dominated by resprouting trees are thought be largely invulnerable more frequent wildfires, empirical data support this assumption lacking. Does fire erode tree persistence increasing mortality reducing regeneration, what broader impacts on forest understorey composition? Location Sub‐alpine open Eucalyptus pauciflora forests, Australian Alps, Victoria,...
Spectral indices derived from optical remote sensing data have been widely used for fire-severity classification in forests local to global scales. However, comparative analyses of multiple across diverse forest types are few. This represents an information gap fire management agencies areas like temperate south-eastern Australia, which is characterised by a diversity natural that vary structure, and the fire-regeneration strategies dominant trees. We evaluate 10 spectral eight burnt...
Abstract Aim Forest carbon storage is the result of a multitude interactions among biotic and abiotic factors. Our aim was to use an integrative approach elucidate mechanistic relationships with factors in natural forests temperate Australia, region that has been overlooked global analyses carbon‐biodiversity relations. Location South‐eastern Australia. Time period 2010–2015. Major taxa studied trees 732 plots. Methods We used most comprehensive forest inventory database available for...
Above‐ground biomass in forests is critical to the global carbon cycle as it stores and sequesters from atmosphere. Climate change will disrupt hence understanding how climate other abiotic variables determine forest at broad spatial scales important for validating constraining Earth System models predicting impacts of on stores. We examined importance soil explaining above‐ground distribution across Australian continent using publicly available data 3130 mature sites, 6 ecoregions,...
Wildfires have increased in size and frequency recent decades many biomes, but they also become more severe? This question remains under-examined despite fire severity being a critical aspect of regimes that indicates impacts on ecosystem attributes associated post-fire recovery. We conducted retrospective analysis wildfires larger than 1000 ha south-eastern Australia to examine the extent spatial pattern high-severity burned areas between 1987 2017. High-severity maps were generated from...
Fire regimes are changing across the globe in response to complex interactions between climate, fuel, and fire space time. Despite these interactions, research into predicting regime change is often unidimensional, typically focusing on direct relationships activity increasing chances of erroneous predictions that have ignored feedbacks with, for example, fuel loads availability. Here, we quantify indirect role climate eucalypt dominated landscapes using a novel simulation approach uses...
Previous studies have found negligible effects of single prescribed fires on coarse woody debris (CWD), but the cumulative repeated low‐intensity are unknown. This represents a knowledge gap for environmental management because key tool mitigating wildfire risk, and CWD is recognized as critical to forest biodiversity functioning. We examined attributes stocks (fallen) in mixed‐species eucalypt temperate Australia. Prescribed fire treatments were factorial combination two seasons (Autumn,...
Understanding spatial variation in wildland fuel is central to predicting wildfire behaviour as well current and future fire regimes. Vegetation (plant material) – both live (biomass) dead (necromass) constitutes most aspects of (hereafter ‘fuel’). It therefore likely that factors influencing vegetation structure composition climate, soils, disturbance also will influence associated hazard. Nonetheless, these relationships are poorly understood temperate environments. In this study, we used...
Non-structural carbohydrates (NSCs) form a fundamental yet poorly quantified carbon pool in trees. Studies of NSC seasonality forest trees have seldom measured whole-tree stocks and allocation among organs, are not representative all tree functional types. carbohydrate research has primarily focussed on broadleaf deciduous coniferous evergreen with distinct growing seasons, while remain under-studied despite their different growth phenology. We temporal variation Eucalyptus obliqua L'Hér.,...
Non-structural carbohydrates (NSCs) are crucial to support tree resprouting after disturbances that damage the crown or stem. Epicormic (from stem) could demand more from NSC reserves than basal (following top-kill), since epicormically trees need maintain a greater living biomass. Yet, little is known about use during epicormic resprouting, particularly relative importance of stem and below-ground reserves. We compared distribution magnitude decreases by experimentally removing crowns stems...
Extreme weather can have significant impacts on plant species demography; however, most studies focused responses to a single or small number of extreme events. Long‐term patterns in climate extremes, and how they shaped contemporary distributions, rarely been considered tested. BIOCLIM variables that are commonly used correlative distribution modelling cannot be quantify as generated using long‐term averages therefore do not describe year‐to‐year, temporal variability. We evaluated the...
Abstract The soil in terrestrial and coastal blue carbon ecosystems is an important sink. National inventories require accurate assessments of these to aid conservation, preservation, nature-based climate change mitigation strategies. Here we harmonise measurements from Australia’s apply multi-scale machine learning derive spatially explicit estimates stocks the environmental drivers variation. We find that vegetation are primary variation at continental scale, while ecosystem type, terrain,...
Active management is often mentioned but rarely defined in current policies and strategies for native forests of temperate Australia. Lack clarity about active could mean that to support forest health human involvement with are not fit purpose. In this paper, we summarise the policy context Victoria (as a case study Australia) review representations broader temperate-forest literature, including its place relation associated concepts like adaptive management. Based on review, provide...
