The results come from a heavy storm the previous day or tree pruning. If that happens then the tree gets infected which causes Oak Wilt. The tree where Oak Wilt effects the most is the Red Oak…

Benefits of Natural Forest Fires to Forest Ecology Introduction Since its discovery, fire has fascinated man with its potential. Fire provides light and heat and while it destroys some things that come in contact with it, it is also capable of metamorphosing other things for the overall benefit of life. Natural fires are a routine occurrence in forested areas, especially during hot and dry weather conditions or due to lightning strikes. In the summer of 1988, for example, 42 instances of…

people who believe that it would cause thistle and other brush to grow in its place.

Each year, greenhouse gas levels in the atmosphere increase, thereby increasing the Earth's overall temperature. Global warming could lead to devastating effects on weather patterns, economics, agriculture, and even our health. To prevent or slow down global warming, we need to get people more informed of global warming and take steps…

Add a Title According to the SREX report of the Intergovernmental Panel on Climate Change, a changing climate leads to changes in the frequency, intensity, spatial extent, duration, and timing of extreme weather and climate events, and can result in unprecedented extreme weather and climate events (IPCC, 2012). Especially in the Western United States, wildfires are increasing in frequency, duration, and severity. Wildfires are a major source of particulate matter in the air, mainly during the…
