“…However, it is evident that unchecked spread of these flammable species, particularly Gorse in farmland across most of the country, should be a priority for control. In Spain, Madrigal et al (2012) advocated intensive management of Gorse shrubland to prevent plants exceeding five years of age. At this stage rapid physiological and structural changes considerably increase plant flammability (Madrigal et al 2012), most likely through retention of dead biomass (Dent, Lustig, Buckley and Curran unpubl.…”

“…Studies based in other parts of the world have assessed the flammability of some species that occur in NZ. 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).…”

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'.

“…The flammability of plants is usually assessed by means of laboratory assays in which several methods and devices are used (Etlinger and Beall, 2004;Weise et al, 2005;Madrigal et al, 2012;Ganteaume et al, 2013aGanteaume et al, , 2013b. The epiradiator, or radiant heater, has been used to evaluate flammability parameters in many studies (Valette, 1990;Hernando, 2000;Dimitrakopoulos and Papioannou, 2001;Alessio et al, 2008;Ganteaume et al, 2013a).…”

“…These equivalents respectively are rate of spread, intensity and residence time (Gill and Zylstra 2005). In particular, leaf ignition and flammability are commonly measured or estimated using different methods and under different laboratory conditions (Xanthopoulos and Wakimoto 1993;Ganteaume et al 2011;Madrigal et al 2012). One method to determine either leaf ignition or flammability uses a standard epiradiator (Trabaud 1976;De Lillis et al 2009).…”

Wildfires are common from summer to early fall in Patagonian forests of Argentina. Live fuel moisture content (LFMC) and leaf ignition are important factors for understanding fire behaviour. In this study, we determined seasonal LFMC and leaf ignition of some key fire-prone species of these forests, and their relationships with environmental variables. Species investigated were the native trees ñire (Nothofagus antarctica) and cypress (Austrocedrus chilensis), the understorey tree-like radal (Lomatia hirsuta) and laura (Schinus patagonicus), the bamboo caña colihue (Chusquea culeou), and the non-native black poplar (Populus nigra). LFMC differed among species, with caña colihue having lower values (LFMC ,100%); ñire, laura, cypress, and radal having medium values (110-220%); and black poplar, upper values (.220%). Ignition characteristics differed among species (caña colihue . ñire . radal . cypress . laura . black poplar) and were inversely related to LFMC. Correlations between LFMC and environmental variables were highly significant for caña colihue, significant for ñire, radal, and laura, and weakly significant or non-significant for cypress and black poplar. These results contribute to our understanding of fire behaviour, and validate the fuel typology for Patagonian forests. At the same time, they add some useful knowledge for comparison with other fire-prone Mediterranean ecosystems around the world.
