Large woody debris, grains, and the shape of the bed of the stream are the three main providers of flow resistance, and are thus, a major influence on the shape of the stream channel. [1] Some stream channels have less LWD than they would naturally because of removal by watershed managers for flood control and aesthetic reasons.
A combination of heavy livestock grazing and fire-suppression has drastically altered the structure, composition, and diversity of the shortgrass prairie ecosystem on the Great Plains, allowing woody species to dominate many areas and promoting fire-intolerant invasive species. In semi-arid ecosystems where the decomposition of woody material ...
Hammocks tend to occur in locations where fire is not common, or where there is some protection from fire in neighboring ecosystems. Hammocks have begun developing in historic times in areas where fire has been suppressed through human intervention, or where elevations above wetlands have been created by dredging , mining, road and causeway ...
Also referred to as air attack. The use of aircraft in support of ground resources to combat wildfires, often most effective in initial attack in light fuels. air drop The delivery of supplies or fire retardant from the air. Supplies can be dropped by parachute, while retardant is generally released in a single drop of one or more trails, the size of which is determined by the wind and the ...

In the sweltering summer heat, nobody tries to cool off by jumping into a hot tub. In parts of Florida, however, that’s what the ocean has felt like. Earlier this week, sea surface temperatures ...
However, plants have their own ways to survive a fire event or recover after a fire. The strategies can be classified into three types: resist (above-ground parts survive fire), recover (evade mortality by sprouting), and recruit (seed germination after the fire). Fire plays a role as a filter that can select different fire response traits. [6]
