“…Despite likely fuel drying feedbacks we found no evidence of strong soil feedback as most soil variables, other than ammonium, did not vary among fire severity levels or at long unburnt sites. Both fuel/flammability and fire/soil feedbacks have been strongly implicated in driving forest changes in Australian forests where mesic fuels are thought to be less combustible (Dickinson and Kirkpatrick, 1985;Bowman, 2000).…”

“…These include the invasive weeds Gorse (Ulex europaeus) (Núñez-Regueira et al 1996;Madrigal et al 2012) and Radiata Pine (Pinus radiata) (Fonda 2001), other exotic species (e.g. Manna Gum (Eucalyptus viminalis)) and some indigenous NZ species (Mānuka, Akeake (Dodonea viscosa) and Bracken) that occur elsewhere, such as Tasmania (Dickinson and Kirkpatrick 1985). In NZ, multiple studies have assessed the flammability of Gorse (Anderson andAnderson 2009, 2010), whereas the only published comparative assessment of indigenous trees and shrubs is qualitative and derived from expert opinion (Fogarty 2001).…”

Abstract. Fire is an important ecological disturbance in vegetated ecosystems across the globe, and also has considerable impacts on human infrastructure. Vegetation flammability is a key bottom-up control on fire regimes and on the nature of individual fires. Although New Zealand (NZ) historically had low fire frequencies, anthropogenic fires have considerably impacted indigenous vegetation as humans used fire extensively to clear forests. Few studies of vegetation flammability have been undertaken in NZ and only one has compared the flammability of indigenous plants; this was a qualitative assessment derived from expert opinion. We addressed this knowledge gap by measuring the flammability of terminal shoots from a range of trees and shrubs found in NZ. We quantified shoot flammability of 60 indigenous and exotic species, and compared our experimentally derived ranking with expert opinion. The most flammable species was the invasive exotic shrub Gorse (Ulex europaeus), followed by Manna Gum (Eucalyptus viminalis), K% umarahou (Pomaderris kumeraho), Rimu (Dacrydium cupressinum) and Silver Beech (Lophozonia menziesii). Our experimentally derived ranking was strongly correlated with expert opinion, lending support to both methods. Our results are useful to ecologists seeking to understand how fires have and will influence NZ's ecosystems, and for fire managers identifying high-risk landscapes, and low flammability species for 'green firebreaks'.

“…Other features of eucalypt that promote fire spread include heavy litter fall, flammable oils in the foliage, and open crowns bearing pendulous branches, which encourages maximum updraft (Esser 1993). Nevertheless, despite the presence of volatile oils that produce a hot fire, leaves of eucalypt are classed as intermediate in their resistance to combustion, and juvenile leaves are highly resistant to flaming (Dickinson and Kirkpatrick 1985). However, eucalypt is seldom killed by fire (Esser 1993).…”

Forest and fire management planning activities are carried out mostly independently of each other. This paper discusses research aiming at the development of methods and tools that can be used for enhanced integration of forest and fire management planning activities. Specifically, fire damage models were developed for Eucalyptus globulus Labill stands in Portugal. Models are based on easily measurable forest characteristics so that forest managers may predict post-fire mortality based on forest structure. For this purpose, biometric data and fire-damage descriptors from 2005/2006 National Forest Inventory plots and other sample plots within 2006, 2007 and 2008 fire areas were used. A three-step modelling strategy based on logistic regression methods was used. In the first step, a model was developed to predict whether mortality occurs after a wildfire in a eucalypt stand. In the second step the degree of damage caused by wildfires in stands where mortality occurs is quantified (i.e. percentage of mortality). In the third step this mortality is distributed among trees. Data from over 85 plots and 1648 trees were used for modeling purposes. The damage models show that relative damage increases with stand basal area. Tree level mortality models indicate that trees with high diameters, in dominant positions and located in regular stands are less prone to die when a wildfire occurs.
