Forest fires are changing: let’s change the fire management strategy

  
Forest@ - Rivista di Selvicoltura ed Ecologia Forestale, Vol. 14, No. 4. (31 August 2017), pp. 202-205, https://doi.org/10.3832/efor2537-014

Abstract

Forest fires in Italy are changing. More frequent heatwaves and drought increase the flammability of the vegetation; the abandonment of rural land produces 30.000 ha of newly afforested areas each year; and the wildland-urban interface is expanding with the sprawl of urbanized areas. However, forest fires are rarely understood and managed in their complexity. The public opinion is often misinformed on the causes and consequences of fires in the forest. Moreover, fire management relies almost exclusively on extinction and emergency response, ...

 

Mechanisms of plant survival and mortality during drought: why do some plants survive while others succumb to drought?

  
New Phytologist, Vol. 178, No. 4. (1 June 2008), pp. 719-739, https://doi.org/10.1111/j.1469-8137.2008.02436.x

Abstract

Severe droughts have been associated with regional-scale forest mortality worldwide. Climate change is expected to exacerbate regional mortality events; however, prediction remains difficult because the physiological mechanisms underlying drought survival and mortality are poorly understood. We developed a hydraulically based theory considering carbon balance and insect resistance that allowed development and examination of hypotheses regarding survival and mortality. Multiple mechanisms may cause mortality during drought. A common mechanism for plants with isohydric regulation of water status results from avoidance of drought-induced ...

 

Post-fire spread of alien plant species in a mixed broad-leaved forest of the Insubric region

  
Flora - Morphology, Distribution, Functional Ecology of Plants, Vol. 207, No. 1. (January 2012), pp. 19-29, https://doi.org/10.1016/j.flora.2011.07.016

Abstract

How do tree species regenerate and which ecological conditions are required after forest fire in the Insubric region of the Alps? Are indigenous stand-forming tree species resistant over the invasion of alien plant species after such a disturbance? We addressed these questions in a case study in the Swiss canton of Ticino. In April 2006, a surface fire with severe intensity burnt a forest area of 55 ha on a south-facing slope (400–800 m.a.s.l.). The dominant trees in the investigated area ...

 

Recurrent wildfires constrain long-term reproduction ability in Pinus halepensis Mill.

  
International Journal of Wildland Fire, Vol. 17, No. 5. (2008), 579, https://doi.org/10.1071/wf07078

Abstract

Increasing fire recurrence is a major problem threatening Mediterranean-type ecosystems. Moreover, this pattern is predicted to increase owing to global change. Although a reduction in the density and growth of post-fire regeneration is usually observed in recurrently burnt areas, the potential effects on reproductive ability have seldom been explored. The aim of the present study is to investigate whether structural changes induced by fire recurrence may constrain reproduction ability of Pinus halepensis forests. We conducted the current study in Catalonia (NE ...

 

Different approaches to model future burnt area in the Iberian Peninsula

  
Agricultural and Forest Meteorology, Vol. 202 (March 2015), pp. 11-25, https://doi.org/10.1016/j.agrformet.2014.11.018

Abstract

[Highlights] [::] We distinguish four regions with different fire regimes in the Iberian Peninsula. [::] Statistical models (meteorology driven) are developed to reproduce burnt area series. [::] We check performances of RCMs simulating present climate burnt area distributions. [::] Different methods to correcting model biases are tested and applied to RCM outputs. [::] Our models project about 2–3 more times mean burnt area in Iberia around 2075. [Abstract] In this work we developed projections for future fire regimes in the Iberian Peninsula using outputs from Regional Climate Model ...

 

Precipitation dominates fire occurrence in Greece (1900–2010): its dual role in fuel build-up and dryness

  
Natural Hazards and Earth System Science, Vol. 14, No. 1. (03 January 2014), pp. 21-32, https://doi.org/10.5194/nhess-14-21-2014

Abstract

Historical fire records and meteorological observations spanning over one century (1894–2010) were assembled in a database to collect long-term fire and weather data in Greece. Positive/negative events of fire occurrence on an annual basis were considered as the years where the annual values of the examined parameters were above (positive values) or below (negative values) the 95% confidence limits around the trend line of the corresponding parameter. To analyse the association of positive/negative events of fire occurrence with meteorological extremes, we ...

 

On the key role of droughts in the dynamics of summer fires in Mediterranean Europe

  
Scientific Reports, Vol. 7, No. 1. (6 March 2017), 81, https://doi.org/10.1038/s41598-017-00116-9

Abstract

Summer fires frequently rage across Mediterranean Europe, often intensified by high temperatures and droughts. According to the state-of-the-art regional fire risk projections, in forthcoming decades climate effects are expected to become stronger and possibly overcome fire prevention efforts. However, significant uncertainties exist and the direct effect of climate change in regulating fuel moisture (e.g. warmer conditions increasing fuel dryness) could be counterbalanced by the indirect effects on fuel structure (e.g. warmer conditions limiting fuel amount), affecting the transition between climate-driven and ...

 

Fire situation in Greece

  
International Forest Fire News, Vol. 23 (2000), pp. 76-83

Abstract

[Excerpt: Conclusions and Outlook] As can be seen, Greece has a serious fire problem. The money and effort devoted to coping with the problem is significant. Actually, especially in terms of aerial forces, the country should probably be rated first in the world on a per-hectare-protected basis. However, the poor results of the last few years clearly indicate that there is need for improvement, especially in regard to knowledge and organization of the whole effort. Also, there is a clear need for ...

Spatiotemporal variations in wildfire regime and exposure for Sardinia, Italy

  
In Atti del Secondo Congresso Internazionale di Selvicoltura = Proceedings of the Second International Congress of Silviculture (2015), pp. 975-981, https://doi.org/10.4129/2cis-ol-var

Abstract

[Summary] Over the past decades several studies highlighted the increasing risk in the occurrence of large and severe wildfires as well as significant variation in fire regime pattern. In the Mediterranean basin, Sardinia (Italy) has seen a marked reduction in the annual area burned since the 1980s, with a sharp variation in mid-‘90s. Despite this downward trend wildfires still cause considerable financial losses, damages to natural ecosystems, accidents and fatalities. Therefore, efficient wildfire exposure and risk estimation as well as ...

Forest disturbances under climate change

  
Nature Climate Change, Vol. 7, No. 6. (31 May 2017), pp. 395-402, https://doi.org/10.1038/nclimate3303

Abstract

Forest disturbances are sensitive to climate. However, our understanding of disturbance dynamics in response to climatic changes remains incomplete, particularly regarding large-scale patterns, interaction effects and dampening feedbacks. Here we provide a global synthesis of climate change effects on important abiotic (fire, drought, wind, snow and ice) and biotic (insects and pathogens) disturbance agents. Warmer and drier conditions particularly facilitate fire, drought and insect disturbances, while warmer and wetter conditions increase disturbances from wind and pathogens. Widespread interactions between agents are ...

 

Assessing European wild fire vulnerability

  
Geophysical Research Abstracts, Vol. 14 (April 2012), 9452

Abstract

Wild fire vulnerability is a measure of potential socio-economic damage caused by a fire in a specific area. As such it is an important component of long-term fire risk management, helping policy-makers take informed decisions about adequate expenditures for fire prevention and suppression, and to target those regions at highest risk. This paper presents a first approach to assess wild fire vulnerability at the European level. A conservative approach was chosen that assesses the cost of restoring the previous land cover after a potential fire. Based on the CORINE ...

 

Modeling the impacts of climate change on forest fire danger in Europe: sectorial results of the PESETA II Project

  

Abstract

This constitutes a sectorial analysis of the PESETA II project of the European Commission Joint Research Center in the area of wildfires. [\n] Wildfires are a serious threat to European forests, and climate is the most important driving factor affecting wildfire potential over time (Flannigan et al., 2000). Wildfires are an environmental, economic and social problem particularly in the southern European countries, where wildfires regularly burn thousands of hectares of forests and other lands. Changes in wildfire regimes may have strong impacts on natural resources and ecosystems stability, ...

 

Risk of large-scale fires in boreal forests of Finland under changing climate

  
Natural Hazards and Earth System Sciences, Vol. 16, No. 1. (21 January 2016), pp. 239-253, https://doi.org/10.5194/nhess-16-239-2016

Abstract

The target of this work was to assess the impact of projected climate change on forest-fire activity in Finland with special emphasis on large-scale fires. In addition, we were particularly interested to examine the inter-model variability of the projected change of fire danger. For this purpose, we utilized fire statistics covering the period 1996–2014 and consisting of almost 20 000 forest fires, as well as daily meteorological data from five global climate models under representative concentration pathway RCP4.5 and RCP8.5 scenarios. The ...

 

Multi-variable bias correction: application of forest fire risk in present and future climate in Sweden

  
Natural Hazards and Earth System Science, Vol. 15, No. 9. (11 September 2015), pp. 2037-2057, https://doi.org/10.5194/nhess-15-2037-2015

Abstract

As the risk of a forest fire is largely influenced by weather, evaluating its tendency under a changing climate becomes important for management and decision making. Currently, biases in climate models make it difficult to realistically estimate the future climate and consequent impact on fire risk. A distribution-based scaling (DBS) approach was developed as a post-processing tool that intends to correct systematic biases in climate modelling outputs. In this study, we used two projections, one driven by historical reanalysis (ERA40) and ...

 

A review of the combination among global change factors in forests, shrublands and pastures of the Mediterranean Region: beyond drought effects

  
Global and Planetary Change, Vol. 148 (January 2017), pp. 42-54, https://doi.org/10.1016/j.gloplacha.2016.11.012

Abstract

[Highlights] [::] Different global change factors combine causing unprecedented ecological effects. [::] Much more complex interactions arise when combinations occur together.

Modelling long-term fire occurrence factors in Spain by accounting for local variations with geographically weighted regression

  
Natural Hazards and Earth System Science, Vol. 13, No. 2. (11 February 2013), pp. 311-327, https://doi.org/10.5194/nhess-13-311-2013

Abstract

Humans are responsible for most forest fires in Europe, but anthropogenic factors behind these events are still poorly understood. We tried to identify the driving factors of human-caused fire occurrence in Spain by applying two different statistical approaches. Firstly, assuming stationary processes for the whole country, we created models based on multiple linear regression and binary logistic regression to find factors associated with fire density and fire presence, respectively. Secondly, we used geographically weighted regression (GWR) to better understand and explore ...

Sequential disturbance effects of hailstorm and fire on vegetation in a Mediterranean-type ecosystem

  
Ecosystems, Vol. 18, No. 7. (2015), pp. 1121-1134, https://doi.org/10.1007/s10021-015-9886-5

Abstract

Frequency and intensity of disturbance is projected to increase for many ecosystems globally, with uncertain consequences, particularly when disturbances occur in rapid succession. We quantified community response (52 shrub species and the tree Eucalyptus todtiana) to a severe hailstorm followed 2 months later by prescribed fire for a Mediterranean-type shrubland in southwestern Australia. Partial overlap of hailstorm path and fire perimeter provided a unique opportunity to compare storm and fire effects along a storm severity gradient (high–moderate–none) with and without fire. ...

 

How drought-induced forest die-off alters microclimate and increases fuel loadings and fire potentials

  
International Journal of Wildland Fire, Vol. 25, No. 8. (2016), 819, https://doi.org/10.1071/wf15028

Abstract

Forest die-offs associated with drought and heat have recently occurred across the globe, raising concern that associated changes in fuels and microclimate could link initial die-off disturbance to subsequent fire disturbance. Despite widespread concern, little empirical data exist. Following forest die-off in the Northern Jarrah Forest, south-western Australia, we quantified fuel dynamics and associated microclimate for die-off and control plots. Sixteen months post die-off, die-off plots had significantly increased 1-h fuels (11.8 vs 9.8 tonnes ha–1) but not larger fuel classes ...

 

Hydrological impact of forest fires and climate change in a Mediterranean basin

  
Natural Hazards, Vol. 66, No. 2. (2013), pp. 609-628, https://doi.org/10.1007/s11069-012-0503-z

Abstract

Forest fire can modify and accelerate the hydrological response of Mediterranean basins submitted to intense rainfall: during the years following a fire, the effects on the hydrological response may be similar to those produced by the growth of impervious areas. Moreover, climate change and global warming in Mediterranean areas can imply consequences on both flash flood and fire hazards, by amplifying these phenomena. Based on historical events and post-fire experience, a methodology to interpret the impacts of forest fire in terms ...

 

Short-term effects of particulate matter on mortality during forest fires in Southern Europe: results of the MED-PARTICLES Project

  
Occupational and Environmental Medicine, Vol. 72, No. 5. (01 May 2015), pp. 323-329, https://doi.org/10.1136/oemed-2014-102459

Abstract

[Background] An association between occurrence of wildfires and mortality in the exposed population has been observed in several studies with controversial results for cause-specific mortality. In the Mediterranean area, forest fires usually occur during spring–summer, they overlap with Saharan outbreaks, are associated with increased temperature and their health effects are probably due to an increase in particulate matter. [Aim and methods] We analysed the effects of wildfires and particulate matter (PM10) on mortality in 10 southern European cities in Spain, France, Italy ...

Does increased forest protection correspond to higher fire severity in frequent-fire forests of the western United States?

  
Ecosphere, Vol. 7, No. 10. (October 2016), e01492, https://doi.org/10.1002/ecs2.1492

Abstract

There is a widespread view among land managers and others that the protected status of many forestlands in the western United States corresponds with higher fire severity levels due to historical restrictions on logging that contribute to greater amounts of biomass and fuel loading in less intensively managed areas, particularly after decades of fire suppression. This view has led to recent proposals—both administrative and legislative—to reduce or eliminate forest protections and increase some forms of logging based on the belief that ...

 

Evaluating post-fire forest resilience using GIS and multi-criteria analysis: an example from Cape Sounion National Park, Greece

  
Environmental Management In Environmental Management, Vol. 47, No. 3. (4 February 2011), pp. 384-397, https://doi.org/10.1007/s00267-011-9614-7

Abstract

Forest fires are one of the major causes of ecological disturbance in the mediterranean climate ecosystems of the world. Despite the fact that a lot of resources have been invested in fire prevention and suppression, the number of fires occurring in the Mediterranean Basin in the recent decades has continued to markedly increase. The understanding of the relationship between landscape and fire lies, among others, in the identification of the system’s post-fire resilience. In our study, ecological and landscape data are ...

Climate change and forest fires

  
Science of The Total Environment, Vol. 262, No. 3. (15 November 2000), pp. 221-229, https://doi.org/10.1016/s0048-9697(00)00524-6

Abstract

This paper addresses the impacts of climate change on forest fires and describes how this, in turn, will impact on the forests of the United States. In addition to reviewing existing studies on climate change and forest fires we have used two transient general circulation models (GCMs), namely the Hadley Centre and the Canadian GCMs, to estimate fire season severity in the middle of the next century. Ratios of 2×CO2 seasonal severity rating (SSR) over present day SSR were calculated for ...

 

Disturbance and the carbon balance of US forests: a quantitative review of impacts from harvests, fires, insects, and droughts

  
Global and Planetary Change, Vol. 143 (August 2016), pp. 66-80, https://doi.org/10.1016/j.gloplacha.2016.06.002

Abstract

[Highlights] [::] Available data suggest harvest is the leading disturbance impact on C in US forests then fire, windthrow, insects, and droughts. [::] Disturbances in US forests lead to the loss of at least 200 Tg C in live biomass each year on average. [::] Regrowth roughly balances disturbance emissions, with growth enhancements contributing significantly to the net change in forest carbon.

In Ecology, Conservation and Management of Mediterranean Climate Ecosystems - Proceedings of the 10th International Conference on Mediterranean Climate Ecosystems (2004), 20

Abstract

Factors acting as drivers of low resilience to fire in Pinus halepensis ecosystems are being examined. The commonest factor seems to be fire interval. From the several time windows examined, that of, the shortest one ever reported in this type of communities (3 years only) seemed to be the most crucial. From the plant species previously existing on the site woody and herbaceous obligate seeders are mainly affected by this factor. Other factors, affecting mainly pine regeneration, are the abundance of Quercus coccifera individuals in the ...

 

On the relationships between forest fires and weather conditions in Greece from long-term national observations (1894-2010)

  
International Journal of Wildland Fire, Vol. 22, No. 4. (2013), 493, https://doi.org/10.1071/wf12003

Abstract

Historical fire records and meteorological observations, spanning more than 1 century (1894–2010), were gathered and assembled in a database, to provide long-term fire–weather associations. We investigated the relationships between forest fire activity and meteorological parameters and sought to find temporal patterns and trends in these historical records and to identify any linkages between meteorological parameters and fire occurrence in the eastern Mediterranean region. Trend analysis of the time series revealed a statistically significant increase in the number of fires and air ...

 

Atmospheric conditions associated with the exceptional fire season of 2003 in Portugal

  
International Journal of Climatology, Vol. 26, No. 13. (15 November 2006), pp. 1741-1757, https://doi.org/10.1002/joc.1333

Abstract

The summer of 2003 was characterised by exceptional warm weather in Europe, particularly during the first two weeks of August, when a devastating sequence of large fires was observed, reaching an amount of circa 450 000 ha, the largest figure ever recorded in Portugal in modern times. They were concentrated in two relatively confined regions of Portugal and a considerable proportion of burnt area was due to fires started on the 2nd and 3rd of August. [\n] It is shown that the ...

 

A review of the European summer heat wave of 2003

  
Critical Reviews in Environmental Science and Technology, Vol. 40, No. 4. (9 March 2010), pp. 267-306, https://doi.org/10.1080/10643380802238137

Abstract

This paper reviews the European summer heat wave of 2003, with special emphasis on the first half of August 2003, jointly with its significant societal and environmental impact across Western and Central Europe. We show the pattern of record-breaking temperature anomalies, discuss it in the context of the past, and address the role of the main contributing factors responsible for the occurrence and persistence of this event: blocking episodes, soil moisture deficit, and sea surface temperatures. We show that the anticyclonic ...

 

Ground-truthing the Drought Code: field verification of overwinter recharge of forest floor moisture

  
Vol. 268 (1996)

Abstract

[Excerpt:Executive summary] Users of the Canadian Forest Fire Weather Index System are required to precede computation of the Drought Code (DC) component each spring by first calculating a mathematical model of overwinter recharge of moisture in the forest floor. Practical limitations of the mathematical model, required for operational simplicity, have resulted in requests from users for a field sampling procedure that can be used to verify the model, where, and when desired. [\n] This report describes a standard procedure for destructively sampling ...

 

A study of the relation of meteorological variables to monthly provincial area burned by wildfire in Canada (1953-80)

  
Journal of Applied Meteorology and Climatology, Vol. 27, No. 4. (1 April 1988), pp. 441-452, https://doi.org/10.1175/1520-0450(1988)027<0441:asotro>2.0.co;2

Abstract

The relation between meteorological variables and the monthly area burned by wildfire from May to August 1953–80 in nine Canadian “provinces” was investigated. A purely statistical approach to estimating the monthly provincial area burned, using meteorological variables as predictors, succeeded in explaining 30% of the variance west of Lake Nipigon and about 11% east of Lake Nipigon. [\n] Long sequences of days with less than 1.5 mm of rain or days with relative humidities less than 60% proved to have the highest ...

 

Characterizing extreme fire and weather events in the Boreal Shield ecozone of Ontario

  
Agricultural and Forest Meteorology, Vol. 133, No. 1-4. (November 2005), pp. 5-16, https://doi.org/10.1016/j.agrformet.2005.07.015

Abstract

Fire frequency is the most commonly used measure to characterize fire regimes for comparisons across geographical areas or time periods. Within the boreal forest region of the Boreal Shield ecozone of Ontario, fire frequency changes over time and across longitudinal gradients have been associated with drought frequency and large-scale climate processes. While providing evidence that fire regimes differ across areas of the Boreal Shield, fire frequency alone provides little insight into the potential for extreme fire events and the extreme fire ...

 

Ecosystem service supply and vulnerability to global change in Europe

  
Science, Vol. 310, No. 5752. (25 November 2005), pp. 1333-1337, https://doi.org/10.1126/science.1115233

Abstract

Global change will alter the supply of ecosystem services that are vital for human well-being. To investigate ecosystem service supply during the 21st century, we used a range of ecosystem models and scenarios of climate and land-use change to conduct a Europe-wide assessment. Large changes in climate and land use typically resulted in large changes in ecosystem service supply. Some of these trends may be positive (for example, increases in forest area and productivity) or offer opportunities (for example, “surplus land” ...

Climate, weather, and area burned

  
In Forest fires - Behavior and ecological effects (2001), pp. 351-373

Abstract

[Excerpt: Introduction] Forest fires are strongly linked to weather and climate (Flannigan and Harrington, 1988; Johnson, 1992; Swetnam, 1993). Fire has been an integral ecological process since the arrival of vegetation on the landscape. For the purposes of this chapter, we will define weather as short-term processes that result in variations in the atmospheric conditions ranging from minutes to a fire season. Processes that influence the atmosphere over time periods longer than a fire season will be defined as climate. There are several factors that control the ...
