this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

Forest fire is becoming one of the most significant natural disasters at expense ecology and economy. In this article, we develop an effective SqueezeNet based asymmetric encoder-decoder U-shape architecture, Attention U-Net (ATT Squeeze U-Net), mainly functions as extractor a discriminator forest fire. This model takes attention mechanism to highlight useful features suppress irrelevant conten...

Introduction Since human settlement of New Caledonia, the natural disturbance regime has been altered, leading to a number of changes in landscape composition and structure. In particular, the vegetation on ultramafic substrate has been greatly affected by fire and other human disturbances associated with logging and mineral exploration. It is therefore pertinent to ask how the landscape may re...

Yellowstone National Park plays host to numerous microbiological research projects — officially 23, according to the 1996 Investigators' Annual Reports. However, once categories such as aquatic ecology, the study of brucellosis and other wildlife diseases, environmental education, geochemistry and geothermal systems, and vegetation are included, the total came to at least 35 in 1996. Research p...

Applications of LiDAR remote sensing are exploding, while moving from the research to the operational realm. Increasingly, natural resource managers are recognizing the tremendous utility of LiDAR-derived information to make improved decisions. This review provides a cross-section of studies, many recent, that demonstrate the relevance of LiDAR across a suite of terrestrial natural resource dis...

The term “landscape structure” refers to the configuration of vegetation and other land features over a large land area (usually an extent of many square kilometers). A landscape can be regarded as a mosaic composed of patches of different kinds— for example, different forest types, landforms, or human-built structures such as roads. The scientific discipline of landscape ecology is concerned w...

Abstract Recent extreme wildfire seasons in several regions have been associated with exceptionally hot, dry conditions, made more probable by climate change. Much research has focused on fire weather and its drivers, but natural regimes—and their interactions human activities—are far from being comprehensively understood. There is a lack of clarity about the ‘causes’ wildfire, how ecosystems c...
