“…In the Cerrado biome, natural or anthropogenic fires are commonly observed during the dry season (Klink & Machado 2005;Miranda et al 2010), and the data generated by these studies may contribute to the development of conservation and management strategies (Libano & Felfili 2006;Pivello 2011). The aim of the present study was to compare changes in the floristic, structural and dynamic parameters of the woody vegetation between burned sites dominated by typical cerrado and rocky cerrado over time (2009)(2010)(2011)(2012).…”

Differences in substrates can provoke distinct responses in the dynamics of a plant community. We compared changes the floristic, structural and dynamic parameters of the woody vegetation between burned sites dominated by cerrado típico (CT) and cerrado rupestre (CR), which is characterized by the presence of rocky outcrops, over time. We set up 10 plots (20 m × 50 m) at each site. All individuals (diameter of ≥ 3 cm at 30 cm height above the ground) were identified in the two censuses (2009 and 2012) and measured (stem diameter), after an accidental fire in 2008. Changes in floristic parameters between the CT and CR were not significant. However, we found significant differences (p < 0.05) in structural and dynamic parameters, such as density (CT = 1,523; CR = 2,171 ind.ha -1 ), basal area (CT = 8.70; CR = 13.00 m 2 .ha -1 ), recruitment rates (CT = 24.35; CR = 15.14% year -1 ; p = 0.01), gain (CT = 8.58; CR= 3.58% year -1 ), and the loss rates of basal area (CT = 3.88; CR= 2.45% year -1 ). These differences emphasize the need for a differential evaluation of these sites for the development of effective conservation strategies. Key words: changes, density, floristic, mortality, recruitment. ResumoA diferença de substrato pode causar respostas distintas sobre a dinâmica da comunidade vegetal. O objetivo deste trabalho foi comparar os parâmetros florístico, estruturais e de dinâmica da vegetação entre áreas queimadas de cerrado típico (CT) e cerrado rupestre (CR) (presença de afloramentos rochosos) ao longo do tempo. Foram estabelecidas 10 parcelas (20 m × 50 m) em cada local. Todos os indivíduos com diâmetro ≥ 3 cm a 30 cm de altura acima do solo foram identificados e mediu-se o diâmetro do caule tanto em 2009 quanto em 2012, depois de uma queima acidental em 2008. As mudanças nos parâmetros florísticos não foram significativas entre o CT e CR. Entretanto, foram encontradas diferenças (p < 0,05) principalmente com relação aos parâmetros estruturais e de dinâmica, como densidade (CT = 1.523; CR = 2.171 ind.ha -1 ), área basal (CT = 8,70; CR = 13,00 m 2 .ha -1 ), taxa de recrutamento (CT = 24,35; CR= 15,14% ano -1 ; p = 0,01), ganho (CT = 8,58; CR= 3,58% ano -1 ; p = 0,02) e perda em área basal (CT = 3,88; CR= 2,45% ano -1 ). Essas diferenças enfatizam a necessidade de avaliar de forma diferenciada essas fisionomias para criação de futuras estratégias de conservação. Palavras-chave: mudanças, densidade, florística, mortalidade, recrutamento.

“…Overall, these activities are indicative of the sort of investment in stakeholder engagement and consultation that may be needed in countries such as Venezuela , and, indeed, throughout other parts of South America (Mistry et al 2011;Pivello 2011), where strategies of fire suppression and exclusion are key issues addressed in fire management policies (Julio-Alvear 2004). The implementation of community-based savanna fire management is necessary, whether that be as part of an offsets model, another kind of payment for environmental services (PES) opportunity, or simply towards joint management of fire by protected area authorities in collaboration with local indigenous communities.…”

“…As part of traditional practice, fire is used for such purposes as clearing forest for cultivation and for paths, visual communication, deterring dangerous animals, to facilitate hunting and fishing, to cure illnesses, and to reduce fuel loads for the prevention of large catastrophic fires (Mistry et al 2005;Rodríguez and Sletto 2009;McDaniel et al 2005;FIEB 2007;Bilbao et al 2009;Pivello 2011). 4.2 Potential for emissions abatement fire management projects in south American savannas-an example from Venezuela…”

“…Fire is widely used in conversion of natural vegetation into agricultural fields and pasture areas in Mato Grosso, and for the subsequent maintenance of deforested areas (Cochrane et al 1999;Pivello 2011). These land management fires occasionally escape beyond their intended extent, leading to uncontrolled wildfires.…”

“…While natural fire occurrences in the humid Amazonian forests are extremely rare (Cochrane 2003), the seasonally dry Cerrado and Pantanal biomes (IBGE-MMA 2004) experience also some natural fires caused by lightning strikes. However, even in these biomes naturally occurring fires typically result only in small burn scars due to the oncoming rain, while anthropogenic fires in the peak dry season cause the majority of the burning (Pivello 2011). Regardless of the affected biome, fires alter the vegetation structure as well as affect the biological diversity and nutrient flux in a variety of ways (Dwyer et al 2000).…”

Abstract. In this paper we analyse the extent of fire-induced forest degradation in Mato Grosso State, Brazil. We utilise a sample based approach used in a previous pan-tropical deforestation survey to derive information on land cover and burned areas in the two major biomes of Mato Grosso: Amazon and Cerrado. Land cover and burned area are mapped for three years (2000-2005-2010) over 77 sample sites (10 000 ha each) distributed systematically throughout the state which covers 90.337 Mha. Our results indicate continuing forest degradation by fires in the state and potentially increasing fire susceptibility of the Amazon forests, regardless of the decrease in deforestation. 2010 witnessed the most extensive fireinduced forest degradation (,300 000 ha) in the forests of the Amazon biome among the study years, regardless of the fact that the fire season was less severe than in 2005. Deforestation in the Amazon biome in Mato Grosso dropped from 590 000 ha year À1 in the 2000-2005 period to 190 000 ha year À1 in the second half of the decade. The findings of this study advocate the inclusion of forest fire effects into carbon accounting initiatives.
