Predicting conifer establishment post wildfire in mixed conifer forests of the North American Mediterranean-climate zone

  
Ecosphere, Vol. 7, No. 12. (December 2016), e01609, https://doi.org/10.1002/ecs2.1609

Abstract

Due to fire suppression policies, timber harvest, and other management practices over the last century, many low‐ to mid‐elevation forests in semiarid parts of the western United States have accumulated high fuel loads and dense, multi‐layered canopies that are dominated by shade‐tolerant and fire‐sensitive conifers. To a great extent, the future status of western US forests will depend on tree species’ responses to patterns and trends in fire activity and fire behavior and postfire management decisions. This is especially the case ...

 

Extreme wildfire events are linked to global-change-type droughts in the northern Mediterranean

  
Natural Hazards and Earth System Sciences, Vol. 18, No. 3. (16 March 2018), pp. 847-856, https://doi.org/10.5194/nhess-18-847-2018

Abstract

Increasing drought conditions under global warming are expected to alter the frequency and distribution of large and high-intensity wildfires. However, our understanding of the impact of increasing drought on extreme wildfires events remains incomplete. Here, we analyzed the weather conditions associated with the extreme wildfires events that occurred in Mediterranean France during the exceptionally dry summers of 2003 and 2016. We identified that these fires were related to two distinct shifts in the fire weather space towards fire weather conditions that ...

 

Portugal wildfire management in a new era assessing fire risks, resources and reforms

  
(February 2018)

Abstract

[Executive summary] Portugal has one of the highest forest fire risk rankings in Europe. Fire researchers all point to the same combination of contributing factors: shifting demographics with population moving from rural to urban areas, changes in land use with more agricultural and forested areas left unattended and not being maintained, and fragmentation of land ownership patterns that discourage investment in forest management and fire planning. The trend of annual burned area for the last four decades confirms a new level in fire activity in Portugal, despite ...

Assessment and validation of wildfire susceptibility and hazard in Portugal

  
Natural Hazards and Earth System Science, Vol. 10, No. 3. (16 March 2010), pp. 485-497, https://doi.org/10.5194/nhess-10-485-2010

Abstract

A comprehensive methodology to assess forest fire susceptibility, that uses variables of strong spatial correlation, is presented and applied for the Portuguese mainland. Our study is based on a thirty-year chronological series of burnt areas. The first twenty years (1975–1994) are used for statistical modelling, and the last ten (1995–2004) are used for the independent validation of results. The wildfire affected areas are crossed with a set of independent layers that are assumed to be relevant wildfire conditioning factors: elevation, slope, ...

 

Long-term changes of the wildland–urban interface in the Polish Carpathians

  
ISPRS International Journal of Geo-Information, Vol. 7, No. 4. (01 April 2018), 137, https://doi.org/10.3390/ijgi7040137

Abstract

The Wildland–Urban Interface (WUI) is the area where houses and wildland vegetation meet or intermingle, which causes many environmental problems. The current WUI is widespread in many regions, but it is unclear how the WUI evolved, especially in regions where both houses and forest cover have increased. Here we compared WUI change in the Polish Carpathians for 1860 and 2013 in two study areas with different land use history. Our western study area experienced gradual forest increase and housing growth over ...

 

Climate-vegetation-fire interactions and feedbacks: trivial detail or major barrier to projecting the future of the Earth system?

  
Wiley Interdisciplinary Reviews: Climate Change, Vol. 7, No. 6. (1 November 2016), pp. 910-931, https://doi.org/10.1002/wcc.428

Abstract

Fire is a complex process involving interactions and feedbacks between biological, socioeconomic, and physical drivers across multiple spatial and temporal scales. This complexity limits our ability to incorporate fire into Earth system models and project future fire activity under climate change. Conceptual, empirical, and process models have identified the mechanisms and processes driving fire regimes, and provide a useful basis to consider future fire activity. However, these models generally deal with only one component of fire regimes, fire frequency, and do ...

 

Predicting climate change effects on wildfires requires linking processes across scales

  
Wiley Interdisciplinary Reviews: Climate Change, Vol. 2, No. 1. (January 2011), pp. 99-112, https://doi.org/10.1002/wcc.92

Abstract

Accurate process‐based prediction of climate change effects on wildfires requires coupling processes across orders of magnitude of time and space scales, because climate dynamic processes operate at relatively large scales (e.g., hemispherical and centennial), but fire behavior processes operate at relatively small scales (e.g., molecules and microseconds). In this review, we outline some of the current understanding of the processes by which climate/meteorology controls wildfire behavior by focusing on four critical stages of wildfire development: (1) fuel drying, (2) ignition, (3) ...

 

A data-driven approach to assess large fire size generation in Greece

  
Natural Hazards, Vol. 88, No. 3. (2017), pp. 1591-1607, https://doi.org/10.1007/s11069-017-2934-z

Abstract

Identifying factors and drivers which control large fire size generation is critical for planning fire management activities. This study attempts to determine the role of fire suppression tactics and behavior, weather, topography and landscape features on two different datasets of large fire size (500–1000 ha) and very large fire size (>1000 ha) compared to two datasets of small fire size (<50 ha) which occurred in Greece, during the period 1984–2009. In this context, we used a logistic regression (LR) analysis and ...

 

How wildfire risk is related to urban planning and Fire Weather Index in SE France (1990–2013)

  
Science of The Total Environment, Vol. 621 (April 2018), pp. 120-129, https://doi.org/10.1016/j.scitotenv.2017.11.174

Abstract

[Highlights] [::] Land use planning in SE France led to increased housing density in 1990-2012 and maintained WUI wildfire risk constant. [::] The number of buildings increased by 30% but WUI area increased by less than 5% as housing density increased. [::] Fire frequency and burned area increase substantially as Fire Weather Index surpasses a threshold value of 90. [Abstract] Wildfires burn > 450,000 ha of forest every year in Euro-Mediterranean countries. Many fires originate in the Wildland Urban Interface (WUI) where housing density and weather ...

Fire forbids fifty-fifty forest

  
PLOS ONE, Vol. 13, No. 1. (19 January 2018), e0191027, https://doi.org/10.1371/journal.pone.0191027

Abstract

Recent studies have interpreted patterns of remotely sensed tree cover as evidence that forest with intermediate tree cover might be unstable in the tropics, as it will tip into either a closed forest or a more open savanna state. Here we show that across all continents the frequency of wildfires rises sharply as tree cover falls below ~40%. Using a simple empirical model, we hypothesize that the steepness of this pattern causes intermediate tree cover (30‒60%) to be unstable for a ...

 

Rethinking wildfires and forest watersheds

  
Science, Vol. 359, No. 6379. (01 March 2018), pp. 1001.2-1002, https://doi.org/10.1126/science.aar8120

Abstract

[Excerpt] [...] The secondary threats of wildfires to water supply are particularly concerning, as almost two-thirds of municipalities in North America receive their drinking water from forested areas [...]. Key threats include increased potential for erosion, landslides, debris flows, floods, and introduction of contaminants to streams, with potentially catastrophic implications for community infrastructure, drinking water treatment, public health, and aquatic ecosystem health [...]. [\n] Given the rising threats and costs associated with the current wildfire trend, we must change the way we manage ...

 

Agricultural policy can reduce wildfires

  
Science, Vol. 359, No. 6379. (01 March 2018), pp. 1001.1-1001, https://doi.org/10.1126/science.aat1359

Abstract

[Excerpt] [...] Agriculture is an important driver of European wildfires. It is a major source of fire ignitions [...]. Additionally, farmland abandonment and policies promoting forestry increase fire hazard, as they lead to vegetation growth and fuel build-up in the landscape [...]. However, agriculture is also part of the solution. Agricultural areas, such as crops, orchards, and grasslands, are much less fire-prone, particularly if they include irrigated crops [...]. The European Union's Common Agricultural Policy (CAP) is a powerful financial instrument ...

Towards an understanding of the evolutionary role of fire in animals

  
Evolutionary Ecology (2018), pp. 1-13, https://doi.org/10.1007/s10682-018-9927-6

Abstract

Wildfires underpin the dynamics and diversity of many ecosystems worldwide, and plants show a plethora of adaptive traits for persisting recurrent fires. Many fire-prone ecosystems also harbor a rich fauna; however, knowledge about adaptive traits to fire in animals remains poorly explored. We review existing literature and suggest that fire is an important evolutionary driver for animal diversity because (1) many animals are present in fire-prone landscapes and may have structural and phenotypic characters that contribute to adaptation to these open ...

 

Droughts, floods, and wildfire

  
In Climate science special report: fourth national climate assessment, volume I (2017), pp. 231-253, https://doi.org/10.7930/J0CJ8BNN

Abstract

[Excerpt:Key findings] [::1] Recent droughts and associated heat waves have reached record intensity in some regions of the United States; however, by geographical scale and duration, the Dust Bowl era of the 1930s remains the benchmark drought and extreme heat event in the historical record (very high confidence). While by some measures drought has decreased over much of the continental United States in association with long-term increases in precipitation, neither the precipitation increases nor inferred drought decreases have been confidently attributed to ...

 

Adapt to more wildfire in western North American forests as climate changes

  
Proceedings of the National Academy of Sciences, Vol. 114, No. 18. (02 May 2017), pp. 4582-4590, https://doi.org/10.1073/pnas.1617464114

Abstract

Wildfires across western North America have increased in number and size over the past three decades, and this trend will continue in response to further warming. As a consequence, the wildland–urban interface is projected to experience substantially higher risk of climate-driven fires in the coming decades. Although many plants, animals, and ecosystem services benefit from fire, it is unknown how ecosystems will respond to increased burning and warming. Policy and management have focused primarily on specified resilience approaches aimed at resistance ...

 

The interaction of fire, fuels, and climate across Rocky Mountain forests

  
BioScience, Vol. 54, No. 7. (2004), pp. 661-676, https://doi.org/10.1641/0006-3568(2004)054[0661:tioffa]2.0.co;2

Abstract

Understanding the relative influence of fuels and climate on wildfires across the Rocky Mountains is necessary to predict how fires may respond to a changing climate and to define effective fuel management approaches to controlling wildfire in this increasingly populated region. The idea that decades of fire suppression have promoted unnatural fuel accumulation and subsequent unprecedentedly large, severe wildfires across western forests has been developed primarily from studies of dry ponderosa pine forests. However, this model is being applied uncritically across ...

 

Wildfires

  
In Present and future probability of meteorological and hydrological hazards in Europe (2016), pp. 112-118

Abstract

[Excerpt: Introduction] Uncontrolled forest fires impact both natural and built-up environments as well as humans. The occurrence of a forest fire requires the same basic elements as any fire: heat, oxygen and fuel. Preceding and prevailing weather conditions are crucial for setting conditions susceptible to fire in a forest. Drought, high temperatures and pronounced evaporation dry off organic material in forests, i.e. the fuel. Strong wind during/after ignition substantially intensifies spreading of the fire and raises the likelihood of the surface ...

Abstract

Forests cover over a third of the total land area of Europe. In recent years, large forest fires have repeatedly affected Europe, in particular the Mediterranean countries. Fire danger is influenced by weather in the short term, and by climate when considering longer time intervals. In this work, the emphasis is on the direct influence on fire danger of weather and climate. [\n] For climate analysis at the continental scale, a daily high-emission scenario (RCP 8.5) was considered up to the end ...

Unravelling the response of diurnal raptors to land use change in a highly dynamic landscape in northwestern Spain: an approach based on satellite earth observation data

  
European Journal of Wildlife Research, Vol. 63, No. 2. (2017), pp. 1-15, https://doi.org/10.1007/s10344-017-1097-2

Abstract

Land use and land cover change (LULCC) is one of the main components of current anthropogenic global change. Unravelling the ecological response of biodiversity to the combined effect of land use change and other stressors is essential for effective conservation. For this purpose, we used co-inertia analysis to combine LULCC analysis of earth observation satellite data-derived maps and raptor data obtained from road censuses conducted in 2001 and 2014 at sampling unit level (10 km2 spatial resolution), in northwestern Spain (province ...

 

Intentional fire-spreading by “firehawk” raptors in Northern Australia

  
Journal of Ethnobiology, Vol. 37, No. 4. (1 December 2017), pp. 700-718, https://doi.org/10.2993/0278-0771-37.4.700

Abstract

We document Indigenous Ecological Knowledge and non-Indigenous observations of intentional fire-spreading by the fire-foraging raptors Black Kite (Milvus migrans), Whistling Kite (Haliastur sphenurus), and Brown Falcon (Falco berigora) in tropical Australian savannas. Observers report both solo and cooperative attempts, often successful, to spread wildfires intentionally via single-occasion or repeated transport of burning sticks in talons or beaks. This behavior, often represented in sacred ceremonies, is widely known to local people in the Northern Territory, where we carried out ethno-ornithological research from ...

Abstract

Extreme vapor pressure deficits (VPD) have been associated with enhanced wildfire risk. Using one model, we found for 2015/16 that human influences quintupled the risk of extreme VPD for western North America and increased the risk for extratropical Australia. [Excerpt: Introduction] In 2016, about 3.6 million hectares of land burned in the United States and Canada (NIFC 2017; NFD 2017).

Evidence for declining forest resilience to wildfires under climate change

  
Ecology Letters (12 December 2017), https://doi.org/10.1111/ele.12889

Abstract

Forest resilience to climate change is a global concern given the potential effects of increased disturbance activity, warming temperatures and increased moisture stress on plants. We used a multi-regional dataset of 1485 sites across 52 wildfires from the US Rocky Mountains to ask if and how changing climate over the last several decades impacted post-fire tree regeneration, a key indicator of forest resilience. Results highlight significant decreases in tree regeneration in the 21st century. Annual moisture deficits were significantly greater from ...

 

Tamm Review - Shifting global fire regimes: lessons from reburns and research needs

  
Forest Ecology and Management, Vol. 396 (July 2017), pp. 217-233, https://doi.org/10.1016/j.foreco.2017.03.035

Abstract

[Highlights] [::] We reviewed published studies on reburns in fire-adapted ecosystems of the world. [::] Fire regimes often have shifted from frequent to infrequent fire return intervals. [::] Legacies of past burns constrain the spread and severity of future fires. [::] Periodic fire generally favors fire-adapted vegetation and limits closed forests. [::] Better understanding of reburns informs climate change adaptation methods. [Abstract] Across the globe, rising temperatures and altered precipitation patterns have caused persistent regional droughts, lengthened fire seasons, and increased the number of weather-driven extreme fire events. ...

 

Repeated wildfires alter forest recovery of mixed-conifer ecosystems

  
Ecological Applications, Vol. 26, No. 6. (September 2016), pp. 1842-1853, https://doi.org/10.1890/15-1521.1

Abstract

Most models project warmer and drier climates that will contribute to larger and more frequent wildfires. However, it remains unknown how repeated wildfires alter post-fire successional patterns and forest structure. Here, we test the hypothesis that the number of wildfires, as well as the order and severity of wildfire events interact to alter forest structure and vegetation recovery and implications for vegetation management. In 2014, we examined forest structure, composition, and tree regeneration in stands that burned 1–18 yr before a ...

 

US natural resources and climate change: concepts and approaches for management adaptation

  
Environmental Management, Vol. 44, No. 6. (2009), pp. 1001-1021, https://doi.org/10.1007/s00267-009-9345-1

Abstract

Public lands and waters in the United States traditionally have been managed using frameworks and objectives that were established under an implicit assumption of stable climatic conditions. However, projected climatic changes render this assumption invalid. Here, we summarize general principles for management adaptations that have emerged from a major literature review. These general principles cover many topics including: (1) how to assess climate impacts to ecosystem processes that are key to management goals; (2) using management practices to support ecosystem resilience; ...

 

A wildfire risk management concept based on a social-ecological approach in the European Union: Fire Smart Territory

  
International Journal of Disaster Risk Reduction, Vol. 18 (September 2016), pp. 138-153, https://doi.org/10.1016/j.ijdrr.2016.06.005

Abstract

The current wildfire policies in European Union countries have not solved the wildfire problem and probably will not be effective in the future, as all the initiatives focus on suppression and minimize the use of fire embedded in the Traditional Ecologic Knowledge of European communities. The traditional fire use as a tool for land management has been handled and almost criminalized by an urban-centric perspective and anti-fire bias. These policies are poorly adapted to, and cannot cope with, the complex nature ...

 

The role of community policies in defensible space compliance

  
Forest Policy and Economics, Vol. 11, No. 8. (02 December 2009), pp. 570-578, https://doi.org/10.1016/j.forpol.2009.07.004

Abstract

Recently enacted federal and state policies provide incentives, including financial assistance, for local jurisdictions to manage risks associated with wildland fire. This has led to an array of local-level policies designed to encourage homeowners to create fire-safe landscapes. This qualitative study collected data from focus group interviews with homeowners in three diverse communities and used the theory of reasoned action to interpret dimensions of local-level wildland fire policies that are associated with homeowner acceptance of or compliance with defensible space guidelines ...

 

Risk externalities and the problem of wildfire risk

  
Journal of Urban Economics, Vol. 64, No. 2. (September 2008), pp. 488-495, https://doi.org/10.1016/j.jue.2008.05.001

Abstract

Homeowners living in the wildland–urban interface must decide whether or not to create a defensible space around their house in order to mitigate the risk of a wildfire destroying their home. Risk externalities complicate this decision; the risk that one homeowner faces depends on the risk mitigation decisions of neighboring homeowners. This paper models the problem as a game played between neighbors in a wildland–urban interface. The model explains why sub-optimal investment in defensible space is likely and provides insights into ...

 

Thinking of wildfire as a natural hazard

  
Society & Natural Resources, Vol. 17, No. 6. (1 July 2004), pp. 509-516, https://doi.org/10.1080/08941920490452445

Abstract

Natural hazards theory with its emphasis on understanding the human–hazard interaction has much to offer in better understanding how individuals respond to the wildfire hazard. Ironically, very few natural hazards studies have actually looked at wildfires, despite the insights the field might offer. This report is structured around four interrelated questions that are often heard from individuals involved with wildfire management. Examining these four items through the natural hazards lens can demonstrate just a few of the ways the field can ...

The 2017 wildfire season has seen unusually high fire levels in many parts of the world, with extensive and severe fires occurring in Chile, the Mediterranean, Russia, the US, Canada and even Greenland. Is this a sign of things to come? [Excerpt] During January and February, Chile experienced what their president Michelle Bachelet called “The greatest forest disaster in our history”. The nation was not adequately equipped to tackle these fires, leading the government to enact a state of emergency and accept ...

 

Early postfire vegetation recovery of Pinus brutia forests: effects offire severity, prefire stand age, and aspect

  
Turkish Journal of Agriculture and Forestry, Vol. 40 (2016), pp. 723-736, https://doi.org/10.3906/tar-1601-21

Abstract

Forests dominated by serotinous tree species are usually generalized to follow an autosuccessional model of postfire recovery. However, recent studies have suggested that prefire conditions, topography, and idiosyncrasies of the fire disturbance can have notable effects on how such forests respond to fire. We investigated the effects of fire severity, prefire stand age, and aspect (slope orientation) on the early postfire recovery of Pinus brutia forest. The study site was the area of 2008 Serik-Tasağıl Fire, one of the largest forest ...

 

Sun in parts of UK and France blocked out the smoke from wildfires in Spain and Portugal

  
Severe Weather Europe, Vol. 2017 (2017), 111799

Abstract

[Excerpt] [...] Parts of Spain and Portugal are experiencing extreme fires, caused by a combination of a dry spring and summer and likely arson. The thick smoke was advected by southerly winds into the Bay of Biscay, northwestern France (Brittany) and across the United Kingdom. Residents of this area awoke to a dark orange and brown sky, with the Sun either completely blocked or strongly subdued. While smoke from fires being blown large distances is not rare, it is rare for ...

 

How much does weather control fire size and intensity in the Mediterranean region?

  
Annales Geophysicae, Vol. 33, No. 7. (30 July 2015), pp. 931-939, https://doi.org/10.5194/angeo-33-931-2015

Abstract

This study investigates the synoptic conditions favorable to wildfires in the Mediterranean region, in terms of fire intensity and burnt area. As reported in the literature, Mediterranean large wildfires are associated with a blocking situation. However, this study shows the existence of two types of wildfires controlled by the blocking high intensity: (1) fast build-up of a weak blocking produces intense wildfires associated with strong winds which allow propagation over long distances; (2) longer build-up of strong blocking situation produces less ...

 

Size of wildfires in the Euro-Mediterranean region: observations and theoretical analysis

  
Natural Hazards and Earth System Science, Vol. 15, No. 6. (23 June 2015), pp. 1331-1341, https://doi.org/10.5194/nhess-15-1331-2015

Abstract

MODIS (Moderate Resolution Imaging Spectroradiometer) satellite observations of fire size and ERA-Interim meteorological reanalysis are used to derive a relationship between burnt area and wind speed over the Mediterranean region and Eastern Europe. The largest wildfire size does not show a strong response with respect to wind speed in Eastern Europe. In the Mediterranean, as intuitively expected, the burnt area associated with the largest wildfires is an increasing function of wind speed for moderate temperature anomalies. In situations of severe heatwaves, ...

 

Daily synoptic conditions associated with large fire occurrence in Mediterranean France: evidence for a wind-driven fire regime

  
International Journal of Climatology, Vol. 37, No. 1. (January 2017), pp. 524-533, https://doi.org/10.1002/joc.4680

Abstract

Changes in wildfire activity in the Mediterranean area over recent decades increase the need for a better understanding of the fire–weather relationships and for the development of reliable models to improve fire danger prediction. This study analyses daily synoptic and local weather conditions associated with the occurrence of summer large fires (LFs) in Mediterranean France during recent decades (1973–2013). The links between large fire occurrence and synoptic conditions are analysed with composites of sea level pressure and winds at 925 hPa ...

 

Prepare for larger, longer wildfires

  

Abstract

Climate change makes land management more urgent than ever, says Kathie Dello. [Excerpt] [...] Scientists must walk a careful line when attributing specific events to climate change. Wildfires are part of a healthy ecosystem and a fact of life in the western United States. Many aspects of a landscape affect them, including past fire suppression, land use and human carelessness. [\n] But climate change increases the threat: fires that do start are larger and last longer. Warmer summer temperatures mean more evaporation. Overall, ...

 

Polar wildfires and conifer serotiny during the Cretaceous global hothouse

  
Geology (11 October 2017), https://doi.org/10.1130/g39453.1

Abstract

Several highly effective fire-adaptive traits first evolved among modern plants during the mid-Cretaceous, in response to the widespread wildfires promoted by anomalously high atmospheric oxygen (O2) and extreme temperatures. Serotiny, or long-term canopy seed storage, is a fire-adaptive strategy common among plants living in fire-prone areas today, but evidence of this strategy has been lacking from the fossil record. Deposits of abundant fossil charcoal from sedimentary successions of the Chatham Islands, New Zealand, record wildfires in the south polar regions (75°–80°S) ...

 

Assessing risk and adaptation options to fires and windstorms in European forestry

  
Mitigation and Adaptation Strategies for Global Change In Mitigation and Adaptation Strategies for Global Change, Vol. 15, No. 7. (10 July 2010), pp. 681-701, https://doi.org/10.1007/s11027-010-9243-0

Abstract

Risks can generally be described as the combination of hazard, exposure and vulnerability. Using this framework, we evaluated the historical and future development of risk of fire and wind damage in European forestry at the national level. Fire risk is expected to increase, mainly as a consequence of an increase in fire hazard, defined as the Fire Weather Index in summer. Exposure, defined as forest area, is expected to increase slightly as a consequence of active afforestation and abandonment of marginal ...

 

Forest fires in Europe, Middle East and North Africa 2016

  

Abstract

[Excerpt: Foreword] Forests, agricultural land and natural areas continue to burn, both within and outside Europe. Lives of European citizens are lost and endangered. By early September 2017, wildfires have already burnt nearly 700 000 ha of land in the EU; hence this season will most likely be remembered as one of the most devastating wildfire seasons in Europe since records began. Moreover, sadly this year’s fires have taken a huge toll of lives in Southern Europe. Extreme weather conditions such ...

 

Large wildland fires and extreme temperatures in Sardinia (Italy)

  
iForest - Biogeosciences and Forestry, Vol. 7, No. 3. (02 June 2014), pp. 162-169, https://doi.org/10.3832/ifor1090-007

Abstract

Heat-wave events are commonly recognized as adverse impacts on agriculture, forests, and economic activities. Several studies showed that future climate changes in the western Mediterranean Basin will lead to an increase in extreme weather events, mainly in the summer season. For this reason, it is crucial to improve our knowledge and investigate the effects of extreme temperature events on wildland fire activity. This work analyses the relation between high temperature days (air temperature higher than 25°C at 850hPa) and large wildland ...

 

Forest fires

  
In EMEP/EEA air pollutant emission inventory guidebook 2016 - Technical guidance to prepare national emission inventories, Vol. 21/2016 (2016), 11.B, https://doi.org/10.2800/247535

Abstract

[Excerpt: Overview] This chapter describes emissions from (naturally or man-induced) burning of non-managed and managed forests and other vegetation, excluding agricultural burning of stubble, etc. This includes domestic fires (fuel wood-, crop residue-, dung and charcoal burning) as well as open vegetation fires (forest, shrub- , grass- and cropland burning). According to Barbosa (2006, personal communication), 95 % of the forest fires in the Mediterranean region are related to human impact (negligence, arson, etc.). For the boreal area, Molicone et al. (2006) estimate 87 % of forest ...

 

How have past fire disturbances contributed to the current carbon balance of boreal ecosystems?

  
Biogeosciences, Vol. 13, No. 3. (04 February 2016), pp. 675-690, https://doi.org/10.5194/bg-13-675-2016

Abstract

Boreal fires have immediate effects on regional carbon budgets by emitting CO2 into the atmosphere at the time of burning, but they also have legacy effects by initiating a long-term carbon sink during post-fire vegetation recovery. Quantifying these different effects on the current-day pan-boreal (44–84° N) carbon balance and quantifying relative contributions of legacy sinks by past fires is important for understanding and predicting the carbon dynamics in this region. Here we used the global dynamic vegetation model ORCHIDEE–SPITFIRE (Organising Carbon and ...

 

Describing wildland surface fuel loading for fire management: a review of approaches, methods and systems

  
International Journal of Wildland Fire, Vol. 22, No. 1. (2013), 51, https://doi.org/10.1071/wf11139

Abstract

Wildland fuelbeds are exceptionally complex, consisting of diverse particles of many sizes, types and shapes with abundances and properties that are highly variable in time and space. This complexity makes it difficult to accurately describe, classify, sample and map fuels for wildland fire research and management. As a result, many fire behaviour and effects software prediction systems use a generalised description of fuels to simplify data collection and entry into various computer programs. There are several major fuel description systems currently ...
