{"title":"Modelling the Behavior and Extent of Mid-Holocene Lightning-Caused Fires in Portugal","authors":"Paulo Fernandes, N. Guiomar, David A. Davim","doi":"10.3390/environsciproc2022017089","DOIUrl":"https://doi.org/10.3390/environsciproc2022017089","url":null,"abstract":": Fires of natural origin are usually a very small fraction of the total number of ﬁres in southern Europe, and as such, they are not relevant to contemporary ﬁre regimes and policies, even if they occasionally develop into large-scale conﬂagrations. However, lighting-caused ﬁres might have been a relevant landscape-level disturbance prior to the anthropogenic control exerted through land use and land cover, ﬁre use, and wildﬁre suppression. Our goal was to simulate ﬁre behavior characteristics (rate of spread, ﬁreline intensity) for recent (2001–2020) individual lightning ﬁres occurring in Portugal but under a mid-Holocene landscape context, i.e., just before the human-induced Neolithic disturbances, including burning. We selected three study areas (1240–2615 km 2 ) with distinctively high densities of lightning ﬁres (4.4–7.0 per 100 km 2 per year) and quantiﬁed deciduous broadleaved forest, evergreen broadleaved forest and shrubland cover within each area at 6 ka BP (before present) by combining mapped forest cover (from a palynological reconstruction) and potential natural vegetation series. Then, we simulated the unbounded hourly spread of each ﬁre until its natural extinction (determined by fuel moisture) and allowing for smoldering-only periods with subsequent reactivation, using a suite of selected semi-empirical and empirical models and ERA5-Land (ECMWF, Reading, UK) reanalysis weather data for the location and duration of the event. The simulations considered uncertainty in vegetation cover and in the likelihood of ﬁre reactivation after light rainfall. The unbounded ﬁre size exceeded observed ﬁre size by up to four orders of magnitude. Preliminary results for one of the study areas suggest an infrequent and mixed-severity natural ﬁre regime affecting about 1–4% of the landscape every year. The study offers increased understanding of the past regime and ecological role of natural ﬁre in the Mediterranean basin and can inform improved ﬁre management policies in the region.","PeriodicalId":291013,"journal":{"name":"The Third International Conference on Fire Behavior and Risk","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129360893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jain","doi":"10.3390/environsciproc2022017085","DOIUrl":"https://doi.org/10.3390/environsciproc2022017085","url":null,"abstract":": The broadleaf tree species of the boreal biome of Canada have low ﬂammability compared to conifers, which is in large part due to the high moisture content of their foliage. However, there is a period following snowmelt and prior to leaf budding (i.e., greenup), termed the ‘spring window’ by ﬁre managers, when these forests are more conducive to ﬁre ignition and spread. The goal of this study was to evaluate the length and variability of the spring window from year to year across ecological regions of boreal Canada and to determine whether it is associated with an increased number of human-caused wildﬁres. We used remotely sensed descriptions of snow cover and greenup to describe the annual spring window for nine ecological regions from 2001 to 2018. Then, we statistically compared the timing of the windows and associated the temporal patterns of ﬁre-conducive weather to human-caused wildﬁre occurrence. The results show a positive association between the number of human-caused wildﬁres and the timing of the spring window in only two of the eight regions (the Boreal Plain and Taiga Plain, both in western Canada); however, these are two of the most ﬁre-active areas in the country. A speciﬁc set of factors must coincide for regional ﬁre regimes to exhibit a ﬁre-prone spring window: (i) a relatively high (>20%) proportion of broadleaf forest cover, (ii) a high load of human ignitions (because lighting is rare in the spring), and (ii) frequent windy and dry weather conditions. Although the ﬁre regimes that are active in the springtime are mostly conﬁned to parts of western Canada at present, other areas of boreal Canada may see an increase in spring wildﬁres if projected climatic changes are borne out and if a growing number of people settle into boreal wildlands.","PeriodicalId":291013,"journal":{"name":"The Third International Conference on Fire Behavior and Risk","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121818819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
