The shortcomings of wildfire spread modeling systems and the widespread use of their outcomes in fire management decisions render the evaluation of fire simulation results crucial for model calibration and improvement. This study proposes an exploratory evaluation framework of fire growth simulations using satellite active fire data.
Trees are beautiful complex adaptive organisms. As we see them standing immobile, deeply rooted to the ground and unable to move, we may think that they are defenceless to any change happening to their surrounding environment. In the case of drought, trees have evolved to use different strategies for facing water stress. However, intense and repeated droughts can induce changes in carbon allocation, regeneration rates and mortality. As the frequency and intensity of droughts are expected to increase in many regions due to climate change,Continue reading
The extent of fires, their periodicity and their impact on terrestrial communities is always a concern. Wildfires play an important role in shaping landscapes and as a source of CO2 and particulate matter. Modeling the spatial variability of wildfire extent is an important subject in order to understand and to predict future trends on their effect in landscape changes.
Insect pests are a major threat to many forests worldwide, from boreal to tropical forest ecosystems. Some pests exhibit periodical outbreaks, after which their populations often crash as a result of natural biological control. In this study, authors assessed the performance of aerial spraying of insecticides on pine woodland stands to control pine processionary moth Thaumetopoea pityocampa (PPM) outbreaks in southern Spain.
Title of this post comes directly from recently published research paper. The international team of specialists has recently provided an overview of forest productivity changes in different forest regions in Europe under climate change, and tried to divide these changes into effects induced by climate change alone, and by climate change and forest disturbances. Read more what they have found!
The U.S. forests have been affected by dramatic land cover change over the past few centuries. In a paper published in PLoS One one month ago, Dr. Mountrakis and Sheng Yang, a graduate student, tried slicing deforestation a different way. Read more about a new way to measure deforestation, i.e. forest attrition distance, and and where in the U.S. it was higher!
Recently, drones have become very helpful in forest practices. This time, drones not only helped scientists to discover a new ‘Stonhenge’ in the Amazonian rainforest, but helped also to understand the forestry practices of prehistoric settlers in this area. Ecologists can be a bit shocked, as this discovery reverses assumptions that the rainforest ecosystem has been untouched by humans for millenia.
Protected areas (PAs) are the main instrument for biodiversity conservation, which has triggered the development of numerous indicators and assessments on their coverage, performance and efficiency. The connectivity of the PA networks at a global scale has however been much less explored; previous studies have either focused on particular regions of the world or have only considered some types of PAs.
Have you ever thought how to evaluate state forest institutions in your home countries? Researchers from Poland, Serbia and Germany have used a forest policy model to evaluate the activity of State Forests and Ministry of Environment in Poland. Read more what they have found, and think how such a study can be applied to state forest institutions in your home country.
