Sentence examples for grassland fire from inspiring English sources

According to the US Environmental Protection Agency, peat fires burn at lower temperatures and produce smoke that is more harmful, and in larger quantities, than the average forest fire or grassland fire does.

Now, scientists using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA's Terra and Aqua satellites have pieced together a decade-long global tour of the world's fires, from waves of grassland fire sweeping across Africa, "the fire continent," to agricultural fires in Asia and to catastrophic wildfires in the western United States.

Particular studies included the analyses of the content of dens occupied by small carnivores, the effects of a grassland fire in a vertebrate assemblage, the modifications produced by a local rodent -vizcacha- in the landscape, and the damage generated by pumas in guanaco carcasses.

It is therefore not possible to specify a threshold ratio at which charcoal particles are indicative of grassland fire, and the practical application of the principle is likely to rely on corroboration from other sources of evidence.

Umbanhowar and McGrath (1998) concluded that the mean aspect ratio of the best-fitting ellipse is a usable indicator of whether an assemblage of charcoal particles (125 250 μm) originated from a grassland fire or a forest fire.

This is demonstrated by the work of Daniau et al. (2013), who argue that periods that show an increase in microcharcoal aspect ratio in the Holocene record of southern Africa indicate an increase in grassland fire as a proportion of total biomass burning.

The soil layer, always thin, has been completely washed away in places, often after grassland fires or overgrazing have destroyed the protective vegetation cover.

In soil systems with char input of fairly consistent chemical composition, as they occur in prescribed grassland fires, f may be directly obtained from model chars produced from the respective vegetation cover.

The second approach, using changes in the refractive index caused by heating of phytoliths, was not effective within the temperature range typical of grassland fires, and was prone to rehydration effects in the soil environment.

The methodology presented in this study can support the design and optimization of fuel management programs and policies in agro-pastoral areas of the Mediterranean Basin and herbaceous type landscapes elsewhere, where recurrent grassland fires pose a threat to rural communities, farms and infrastructures.

Annual grassland fires in southern Vietnam can be attributed in part to the destruction of forested areas by US military herbicides, explosives, and mechanical land clearing and burning operations during the Vietnam War.
