“…However, when fires become too frequent for the vegetation to recover, both the flora and avifauna are likely to become seriously negatively affected to the point that recovery becomes impossible. Since burned forests have an increased susceptibility for fire due to increased fuel loads and the more open forest structure (Uhl and Buschbacher 1985;Uhl et al 1988;Cochrane and Schulze 1999;Cochrane 2003), fire prevention (perhaps through construction of fire break networks) should be a main aim of any burned forest conservation strategy. …”

Abstract. Our current understanding of bird community responses to tropical forest fires is limited and strongly geographically biased towards South America. Here we used the circular plot method to carry out complete bird inventories in undisturbed, once burned (1998) and twice burned forests (1983 and 1998) in East Kalimantan (Indonesia). Additionally, environmental variables were measured within a 25 m radius of each plot. Three years after fire the number of birds and bird species were similar for undisturbed and burned forests, but species diversity and turnover were significantly lower in the burned forests. The bird species composition also differed significantly between undisturbed and burned forests, with a strong decline of closed forest preferring bird species accompanied by a strong increase in degraded forest preferring species in burned forests. These differences were strongly related to differences in environmental conditions such as shifts in vegetation cover and layering and differences in ground and understorey vegetation structure. We also found significant shifts in body mass distribution, foraging height and feeding guilds between the bird communities in unburned and burned forests. Surprisingly, repeated burning did not lead to increasing impoverishment of the avifauna, and both once and twice burned forests still contained most of the bird species that were also present in undisturbed forest, even though their densities were considerably lowered.

“…Uhl & Buschbacher (1985) and Fredericksen & Putz (2003) identified these activities as potential causes for fire ignition and associated them with an increased susceptibility of forests to fire. Also Gossow & Frank (2003) argue that salvage harvesting carried out when wind blows can lead to subsequent burns as a consequence of inappropriate engineering techniques.…”

© iForest -Biogeosciences and Forestry IntroductionFire danger is generally understood as the likelihood of a fire to occur (Chuvieco & Congalton 1989). In fire danger assessments the evaluation of the chances of fire ignition is generally done by identifying the contributing factors and their integration into an index quantifying the level of danger (Chuvieco et al. 2003, Sebastián-López et al. 2008. For the probability of a fire to occur, two agents are identified: natural (predominantly lightning) and anthropogenic causes, which are mainly related to human activities. In this context, the probability of human-caused fire ignition is the result of the direct or indirect presence of human activity in the landscape (Martinez et al. 2009). International studies indicate that roughly 90% of forest fires are human-caused, whereas only a small percentage of forest fires have natural causes, i.e., lightning (Cardille et al. 2001, Grissino-Mayer et al. 2004, Mollicone et al. 2006, Vacik et al. 2011. In Europe, human activities account for the majority of fire ignition (Leone et al. 2002, Catry et al. 2009, Martinez et al. 2009).Various goods and services provided by forests such as water supply, carbon sinks, recreation and protection services are most likely to be impacted by wildfires (Wotton et al. 2003, Grissino-Mayer et al. 2004, Brown et al. 2004, Fried et al. 2004, Catry et al. 2009, Dumas et al. 2008, Weibel et al. 2009). Especially in the densely populated European mountain forests the danger of fire ignition is of high significance for the maintenance of its ecosystem goods and services as these ecosystems are very sensitive to environmental changes (Steininger & WeckHannemann 2002, Lindner et al. 2010. Additionally the economic value of goods and services of the alpine region experiences an increased recognition especially through sporting activities and outdoor recreation (Hall & Page 2009). Furthermore, the alpine region is crossed by important transit and trade routes. They aid in promoting tourism in the mountainous regions across Europe (Gambino & Romano 2003, Nordregio 2004, Brauchle 2006, which is leading to an increased development of touristic infrastructure besides the extensive use by naturebased tourism (Gambino & Romano 2003, Heinrichs et al. 2010). The herewith associated rise in pressure on forests through a growing number of tourists is potentially increasing danger of fire ignition. The increasing significance of transportation for the supply of living goods as well as for the provision of access to services potentially affects fire ignition as well. Several international studies have shown the significance of the distance of forest fires to roads, settlements and infrastructure, or specific land uses or even its abandonment as predisposition for fire ignition (Vega-Garcia et al. 1995, Goldammer 2003, Kalabokidis et al. 2002, Catry et al. 2009, Martinez et al. 2009).Although human factors are relatively important when analyzing forest fire ignition, little attention has been paid to their s...

“…Além disso, a rápida expansão das indústrias madeireira . e de mineração está promovendo desmatamento (Fearnside 1990;Nepstad et al 1997) através da criação de redes extensivas de estradas que aumentam grandemente o acesso de colonizadores, fazendeiros e caçadores à floresta (Uhl & Buschbacher 1985;Laurance 2001). O planejamento do uso da terra na Amazônia é também repleto de problemas compõe-se de um mosaico de zoneamentos individuais em cada um dos nove estados da Amazônia, muitos dos quais são fortemente influenciados por usuários locais de recursos e pressão de grupos organizados Finalmente, a rápida expansão da população na Amazônia, que cresceu de cerca de 2.5 milhões em 1960 para os mais de 20 milhões atuais (IBGE 2000), está também aumentando as pressões sobre a floresta.…”

O desmatamento está se acelerando na Amazônia brasileira?

IRecent studies suggest that deforestation rates in the Brazilian Amazon could increase sharply in the future as a result of over $40 billion in planned investments in highway paving and major new infrastructure projects in the region. These studies have been challenged by several Brazilian ministries, which assert that recent improvements in environmental laws, enforcement, and public attitudes have fundamentally reduced the threat posed to forests by such projects. We tested the notion that hazards to Amazonian forests have declined over the last decade by assessing available data on yr ). Moreover, correlation and regression analyses reveal that both absolute and per-capita rates of forest loss accelerated significantly over the last decade. These trends fail to support the assertion that deforestation pressure in Amazonian forests has been brought under control. We suggest that poor enforcement of existing environmental laws, rapidly expanding logging and mining industries, increasing population pressure, and other challenges are greatly hindering efforts to limit the environmental impacts of development activities in Brazilian Amazonia.
