Understanding spatial controls on wildfires is important when designing adaptive fire management plans and optimizing fuel treatment locations on a forest landscape. Previous research about this topic focused primarily on spatial controls for fire origin locations alone. Fire spread and behavior were largely overlooked. This paper contrasts the relative importance of biotic, abiotic, and anthro...

Many studies have identified drivers of deforestation throughout the tropics and, in most cases, have recognised differences in the level of threat. However, only a few have also looked at the temporal and spatial dynamics by which those drivers act, which is critical for assessing the conservation of biodiversity as well as for landscape planning. In this study, we analyse land cover change be...

Forest fires have been causing serious damages and threats in Turkey especially over Aegean and Mediterranean Regions. Damage assessment as the result of a forest fire occurred on 10th August 2009 in Seferihisar district of Izmir, Turkey was conducted in this study. SPOT 4 images obtained before (01.08.2008) and after (31.08.2009) the fire were used in this study. Several digital image processi...

A steadily increasing number of fires and the high intensity of fire seasons every 4 to 5 years have marked the last two decades in Spain. A generalized first attack system supported by aircraft and new technologies has achieved a main goal: more than 70 percent of fires burn less than 1 ha. Nevertheless, fuel accumulations on large areas because of rural land abandonment have increased the ris...

The Cat Ba National Park area (Vietnam) with its tropical forest is recognized as being part of the world biodiversity conservation by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and is a well-known destination for tourists, with around 500,000 travelers per year. This area has been the site for many research projects; however, no project has been carried out f...

This study investigates how federal, state, and private corporate forest owners in a fire-prone landscape of southcentral Oregon manage their forests to reduce wildfire hazard and loss to high-severity wildfire. We evaluate the implications of our findings for concepts of social–ecological resilience. Using interview data, we found a high degree of "response diversity" (variation in forest mana...

Questions: Did fire regimes in old-growth Pinus ponderosa forest change with Euro-American settlement compared to the pre-settlement period? Do tree age structures exhibit a pattern of continuous regeneration or is regeneration episodic and related to fire disturbance or fire-free periods? Are the forests compositionally stable? Do trees have a clumped spatial pattern and are clumps evenor mixe...

We examined tree diameter, age structure, and successional trends in 100 montane forest plots to identify the effects of variation in the return interval, severity, and extent of fires on forest structure and dynamics in the southern Cascade Range, California. We classified 100 forest plots into 8 groups based on stand structural characteristics. Median point fire return intervals were shortest...

Land cover is affected by many factors including economic development, climate and natural disturbances such as wildfires. The ability to evaluate how fire regimes may alter future vegetation, and how future vegetation may alter fire regimes, would assist forest managers in planning management actions to be carried out in the face of anticipated socio-economic and climatic change. In this paper...

The temperate deciduous species Nothofagus glauca (Phil.) Krasser exhibits characteristics commonly found in fire-adapted vegetation, yet the role of fire in the evolutionary history of the vegetation in south-central Chile has not been well investigated. We examined the effects of a wildfire on early succession in a Nothofagus glauca forest in the Coastal Cordillera of south-central Chile by c...
