Primary succession isn’t likely to occur in the UK as there isn’t much bare rock left. Secondary succession is when an area that was once colonised by plants, then the plants are suddenly removed. For example in a forest fire, as a result of this succession has to start again. Secondary succession is much faster than primary succession and will reach climatic climax much sooner. This is because there will still be a lot nutrients and soil left behind from the previous ecosystem.
Introduction: Organisms can have a positive or negative effect on the environment through its interrelated interactions. For example, humans have had a largely negative effect on environments through deforestation and air and water pollution. Through deforestation (a direct action) right here on the Kennesaw State University Campus, the communities within the forest has been wiped out. The organisms in that community have been forced to either flee or face death. Temperature is considered to be an extremely important abiotic factor due to the fact that it is the driving factor behind a variety of chemical reactions, which are necessary for some biological functions.
Wildland Fire Prevention Abstract Living in a house surrounded by nature and wildlands can be peaceful and beautiful, but it can also be risky. Wildfires that spread into wildland-urban interface (WUI) communities can be extremely costly in structural losses. The 1991 Oakland and 2007 Witch Creek fires in California resulted in property losses of $2.7B and $1.5B, respectively. The risk of a high intensity wildland fire, is rising in many wildland ecosystems, and with it comes an increased risk to homes in this interface area. The good news for people living in wildland settings is that you can do many things to protect your home even before a wildfire gets started.
Ecologically, renewal begins almost immediately; however, if left to do so naturally the process will be slow. Once the dead wood is removed and new trees are planted the regeneration phase is sped up to make safer and productive habitat for all of the forest’s plants and habitat. The global warming trend that we see being aggravated by the MPB epidemic will gradually renew balance and the new forests will begin to capture emissions and create oxygen, in turn creating a healthy
Not only is the beetle epidemic killing off the ecosystem for the Grizzly Bears, it is also contributing to this little problem we keep hearing about on the news, and by Politian’s, Global Warming. We hear about it all the time, witness its effects every season, but some people still don’t believe it. The way that the Pine Beetle is affecting Global Warming is that it is changing the lush green pine forest into brown dead zones that are releasing carbon into the atmosphere. The Pine Beetle outbreak is actually threatening the balance of carbon in the region (Ira Platow 1). Carbon is a greenhouse gas, this means it has heat trapping features so it retains heat from the sun and gradually heats up the
Tree To¬¬¬ps Valley Discussion Questions: 7/1/12 2) What factors would account for the differences in tree species from the higher elevations of Tree Tops Valley, where pine trees dominated, to the lower part of the valley, which seemed to be mostly broad-leafed trees? In the higher elevations pine trees dominated due to the type of soil and the amount of sunlight available for the trees. The lower part of the valley had small spring-fed streams interlacing the growth of broad-leafed trees. Also, it is too cold at higher elevations for broad-leafed trees to survive. The valley and surrounding hillsides included different species such as black walnut hardwoods, red and silver maple, beech, red and white oaks, sycamores, white ash, yellow poplar, black and pin cherries, and some softer wooded aspen, sweet birch, and American basswood (a.k.a.
In the last century, many naturally occurring fires were put out immediately as rangers feared it would ruin the national park. However, this resulted in an incredible buildup of dead wood and undergrows that fueled catastrophic infernos. Today, the National Park firefighters manage and allow naturally occurring fires to burn or set controlled fires in order to maintain a balance. The Giant Sequoia trees are heavily dependent upon the fires as it needs fire to reproduce. When a fire burns, the heat opens up their seed cones which allows for their seeds to be released.
The shelters are able to shield trapped firefighters from the radiant heat of the fire, as well as give them a small amount of breathable air amidst the superheated gases. Because grass is such a light flashy fuel, in grass fires it is known that most firefighters die from the inhalation of superheated gases and actually do not burn to death. Having a fire shelter would have given the men the few seconds or minutes needed to breath while the fire quickly burned past
Yet I think the worst part is the natural resources like trees that will be cut down to make room for the machinery and drilling as many of those have been there for years. Along with the trees and forest come the wildlife animals that have their home in the forest and depend on trees to survive. All these not to include the pollution that comes from all these machines and work that will be done in the
Maya farmers used a method called slash and burn before they began planting crops. Slash and burn farming was a lot of hard work for Maya farmers. First, the farmer cut down all the trees in the area he wanted to plant crops in. Cutting down the trees was the “slash part” of the slash and burn farming method. Next, he burned the tree stumps, and the trees he had cut down.
