The Characterization of Fires in Relation to Ecological Studies, with an Introduction by Neil Burrows

Authors: A.G. McArthur and N.P. Cheney
Pages: 1-9
DOI: 10.4996/fireecology.1101001

Literature dealing with the effects of fire on vegetation and soil has been adequately summarized by Hare (1961).  In some two hundred references there is almost a complete absence of a precise description of the type of fire causing the various effects described.

The pioneer Australian study of the effect of fire on soil temperature by Beadle (1940), although not describing the type of fire adequately, at least described the type of fuel in which the fires burnt and gave some dimensions whereby a reasonable estimate of the fire energy could be determined.

Ecological Implications of Fine-Scale Fire Patchiness and Severity in Tropical Savannas of Northern Australia

Authors: Sofia L.J. Oliveira, Manuel L. Campagnolo, Owen F. Price, Andrew C. Edwards, Jeremy Russell-Smith, and José M.C. Pereira
Pages: 10-31
DOI: 10.4996/fireecology.1101010

Understanding fine-scale fire patchiness has significant implications for ecological processes and biodiversity conservation.  It can affect local extinction of and recolonisation by relatively immobile fauna and poorly seed-dispersed flora in fire-affected areas.  This study assesses fine-scale fire patchiness and severity, and associated implications for biodiversity, in north Australian tropical savanna systems.

Fire Emissions and Carbon Uptake in Severely Burned Lenga Beech (Nothofagus pumilio) Forests of Patagonia, Argentina

Authors: Maria Lila Bertolin, Maria Florencia Urretavizcaya, and Guillermo Emilio Defossé
Pages: 32-54
DOI: 10.4996/fireecology.1101032

Forest wildfires are recognized as sources of CO2 and other greenhouse gases (GHG) that, altering the dynamics between terrestrial and atmospheric carbon (C) exchange, influence global climate.  In central Andean Patagonia, Argentina, severe wildfires affect temperate lenga beech (Nothofagus pumilio Poepp. & Endl. Krasser) forests, thereby increasing atmospheric CO2 emissions and changing natural succession paths.

Fire Regime, Climate, and Vegetation in the Sierras de Córdoba, Argentina

Authors: Juan P. Argañaraz, Gregorio Gavier Pizarro, Marcelo Zak, and Laura M. Bellis
Pages: 55-73
DOI: 10.4996/fireecology.1101055

Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012.  However, little is known about the spatial and temporal patterns of fires and their relationship with climate and vegetation in this area.  Such information is of great value for fire risk assessment and the development of strategies for fire management.  Our main objective was to analyze fire activity in four sierran ranges, assessing which weather and climate conditions were mostly related to fire activity, and which land cover types were mostly burned.

Relative Bark Thickness is Correlated with Tree Species Distributions along a Fire Frequency Gradient

Authors: Jennifer L. Schafer, Bradley P. Breslow, Matthew G. Hohmann, and William A. Hoffmann
Pages: 74-87
DOI: 10.4996/fireecology.1101074

The probability of stem survival after fire is strongly influenced by energy allocation to bark because bark thickness affects heat transfer during fire.  Greater relative investment in inner bark versus outer bark should also enhance survival because of greater moisture content of inner bark.  We measured stem diameter, bark thickness, and habitat preference of five species typical of longleaf pine savannas, and six species characteristic of adjacent wetlands (pocosins), and calculated relative bark thickness, the inner bark proportion, radial growth, and bark accumulation of each species.

Assessment of Experiential Education in Prescribed Burning for Current and Future Natural Resource Managers

Authors: John D. Scasta, John R. Weir, and David M. Engle
Pages: 88-105
DOI: 10.4996/fireecology.1101088

Acquiring experiential prescribed fire education is difficult for college students.  In order to evaluate the effects of instruction on students, we surveyed those who were taking or had completed Oklahoma State University’s (OSU) prescribed fire courses since 2000.  Of those surveyed, 32 were current students and 99 were former students.  We assessed changes in their perception, knowledge, skills, abilities, the total area that they have prescribed burned since leaving OSU, their career trajectories, and how they rated the importance of different types of instruction.

Predicting Burned Areas of Forest Fires: an Artificial Intelligence Approach

Authors: Mauro Castelli, Leonardo Vanneschi, and Aleš Popovič
Pages: 106-118
DOI: 10.4996/fireecology.1101106

Forest fires importantly influence our environment and lives.  The ability of accurately predicting the area that may be involved in a forest fire event may help in optimizing fire management efforts.  Given the complexity of the task, powerful computational tools are needed for predicting the amount of area that will be burned during a forest fire.  The purpose of this study was to develop an intelligent system based on genetic programming for the prediction of burned areas, using only data related to the forest under analysis and meteorological data.

The Effects of Ash and Black Carbon (Biochar) on Germination of Different Tree Species

Authors: Otilia Reyes, Joeri Kaal, Diego Arán, Raquel Gago, Javier Bernal, Juan García-Duro, and Margarita Basanta
Pages: 119-133
DOI: 10.4996/fireecology.1101119

Forest fires generate large amounts of ash and biochar, or black carbon (BC), that cover the soil surface, interacting with the soil’s constituents and its seedbank.  This study concerns reproductive ecology assessments supported by molecular characterisation to improve our understanding of the effects of fire and fire residues on the germination behaviour of 12 arboreal species with a wide geographic distribution.  For this purpose, we analysed the effects of three ash and one BC concentration on the germination of Acacia dealbata Link, A. longifolia (Andrews) Willd., A. mearnsii De Wild., A. melanoxylon R. Br., Pinus nigra Arnold, P. pinaster Aiton, P. radiata D. Don, P. sylvestris L., Quercus ilex L., Q. pyrenaica Willd., Q. robur L., and Q. rubra L.
