Abstract Fire has long been used as a management tool all over the world. In our study we designed 2 experiments to investigate the affect fire has on both organic soil layers and Pinus palustris (Longleaf pine) saplings. For this study, a sapling is a youth Longleaf pine less than 2m in height in addiction to one you can wrap your fingers around. The organic soil layer is made of undecomposed plant matter (litter). Samples were taken from 2 different forests located behind the UNCW campus. A prescribed burn was conducted in Forest B in 2011 and Forest C has not been burned since the 1980’s. In the analysis of our collected data, we expected more Pinus palustris saplings in the recently burned forest and a deeper organic layer in the unburned forest. Quadrats and soil sample cores were used to compile the data. As predicted, there were more Pinus palustris saplings in the recently burned forest. However, organic soil layers greatly varied throughout both forests, and overall there was not a significant difference between the two. Many components could have factored in the mixed depths including temperature, weather, moisture, and slope. However, in many studies on this matter, it is concluded that generally speaking, prescribed burns do not have a significant affect on the organic soil layer unless it was burned within the year.
Introduction Typically considered to be a negative disturbance in an ecosystem, fire, is an essential tool for the management of the
There are many reasons that a controlled fire is very necessary to our environment. It is not only beneficial to nature but also to people as well. For example, many farmers will have controlled fires to improve the land for their livestock. When the land is burned off, new growth will begin to take its place which in turn becomes better "food" for the animals. The new growth is richer and has more nutrients than the old, dried
It will also produce for Nitrogen into the soil, to help more plants and vegetation grow in the future. With the Nitrogen and other additional nutrients in the soil it is helping farmers with their crops getting the nutrients it needs. Fires can also clear forests of insect infestations and potential diseases Warren (2011). Among the other benefits of prescribed burning are: Insect pest control, Removal of exotic, or non-species that compete with native species for nutrients and other needs, Fires occurring in nature can restore ecological balance and facilitate regeneration Warren
It is so horrible to see all of that timber go to waste. Our society depends on timber a lot and we need so much of it to produce so many useful goods. What would happen if we did not have any timber to make homes or proved some type of shelter? We would be lost and have no where to go. Prescribed burns can prevent that great loss of timber and save a lot of trees. Although one purpose of controlled burns is to curve paths for huge forest fires, they are also used to freshen up the area. If an area of trees is left untreated from prescribed burns, the sands are expected to decline in growth (Mitchell 1). Also, to ensure a healthy forest,
Fire has long been understood to have an impact on the ecosystem of our native woodlands, but it is only recently that we have come to understand its importance in maintaining the ecosystem. This report takes samples of the flora structure and growth in two different areas of Anstey Hill Recreation Park. The first was last burnt in 1995, and the second burnt in 2012. The results of these samples can be compared to data sampled in 2011, when the 2012 burnt area had not been burnt since Ash Wednesday in 1983.
Fires can either be natural or anthropogenic, which can depend on any situation. A study conducted in 2004 on a wild fire at Voyageurs National Park in Minnesota, suggests that the fire can
The Appalachians span over a distance of 1,600 miles, ranging across 14 states, from Newfoundland in the North, to Alabama in the South. The Appalachians are the oldest chain of mountains on the North American continent. With forest, comes forest fires, some natural and some prescribed by humans. In order to reduce the calamitous damage caused by natural wildfires, the technique of prescribed fires is used. This is done by diminishing the amounts of trees, shrubs, and brush in the intended area. By doing this, new native plant growth is encouraged and it helps maintain some plant and animal species that depend on the periodic fires. With this man made force comes numerous effects on vegetation, wildlife, and the human impact.
The Burnt Area of Mount Pilot contains mixed stands of competing, seedlings with slower growing Callitris seedlings and re-sprouting Eucalyptus trees. There is few Callitris endlicheri, as the species is fire sensitive and often destroyed by fire, particularly when in quick succession. Prior to the 2003 fire the site was dominated by Callitris species of tree. The seedlings that emerged were mostly Eucalyptus, with less dense Callitris seedlings proving that the growth of Callitris is not consistent with long term site suitability. Surprisingly, more Eucalyptus seedlings died in the first six years of regeneration that Callitris seedlings; competition in co-existence does not determine survivability. The major trend is that the growth of Eucalyptus seedlings is faster than that of Callitris seedlings. The density of Eucalyptus seedlings is shown to effect Callitris seedlings growth which thrives where Eucalyptus seedlings are sparser. Callitris may take 7-15 years to produce sufficient seeds (Cohn, Lunt, Ross, & Bradstock, 2011; I. Lunt, Jones, N., & Petrow, M.,, 2003; I. Lunt, Price, J.,, 2016; Ian D Lunt, Zimmer, & Cheal, 2011; Zimmer, 2012).
The Rim Fire of 2013 ravaged the slopes of the Stanislaus National Forest leaving many areas severely burned and unable to recover. Restoration efforts have been made and 56,000 saplings were planted in 2016 in the most severely burned areas; but the forest still has a long way to recovery. Fires are a naturally occurring hazard in the Stanislaus National Forest, and have contributed to the replenishment, control, and sustainability of the forest; but fires of the Rim Fire's intensity are very rare. The Rim Fire destroyed over 277,314 acres of habitat, harmed many mature trees, and ruined the layers of topsoil, and increased erosion and runoff. The devastation of the Rim Fire would not be have been so intense if it weren’t for past fire
The rising number of high severity wildfires in California has significant ecological, economic, and health impacts. Many western American forests are adapted to frequent low severity fires. However, the majority of these forests, and particularly the mixed conifer forests of California, are not adapted to high intensity fires and do not possess fire resistance adaptations such as serotinous cones to protect seeds. Consequently, high severity fires have significant negative impacts on California forests, and the absence of low severity fires has considerably altered many fundamental ecosystem processes (Miller et al. 2008). Prior to 1900, low severity fires would burn every 6-15 years. Low severity fires are generally non-lethal, have minimal change to the overstory, and kill mainly small trees. In the past, these fires were started naturally by lightning, or by Native Americans who used low severity fires to manage the forests.
The focus of this lesson will be teaching the students to examine the history of wildland fires and their impact on society in America and in their community. Students will explore different approaches to living with fire and will examine various fire management techniques including prescribed fire, fire suppression, and fire prevention. They will take a closer look at the Copper King Fire in Montana, and will conduct a research project of wildfire history in another state. Students will also gain a better understanding of the role of fire in a particular culture and the importance of wildfire in the ecosystem. They will also understand ways to reduce wildfire risk around their home and community. Furthermore, students will increase their knowledge
First, the reading posits that, yellow stone fire caused catastrophic damage to the park and trees. However, the professor refutes this point by saying that the fire vanished some plants and trees, but it left with the collagen that helps the new plants and trees to grow. He says that the fire gives an opportunity to new plants to grow. This explains that fire could not damage the vegetation, and trees, however, it creates an environment for new plants to grow.
While not all the effects of prescribed burns are known some are very evident. The first of these common effects is that vegetation and fallen dead material are burned creating an open forest floor. This eliminates any fuel that could contribute to a high intensity fire in the future. When the fire burns the organic material in the forest, nutrient rich ash is left behind. When the first rain comes, the nutrients in the ash dissolve into the soil for the new plants to use. This process is called nutrient recycling. These nutrients left in the soil are a good source of food for the young plants that will begin to grow back. Another outcome of prescribed fire is that new growth begins immediately after the fires have been extinguished. Within
Projecting the effects of fire suppression and possible cumulative effects of fire suppression and other disturbances are vital management tasks moving forward into forestry planning strategies for the future. Although the long-term effects of fire suppression in the Pacific Northwest have been monitored since the early 1900’s, it is challenging to decipher relationships between the cumulative effects of a century of suppression alongside climate change, insect outbreaks and disease and plan how to combat them effectively.
Humans have been changing the Western forests' fire system since the settlement by the Europeans and now we are experiencing the consequences of those changes. During the summer of 2002, 6.9 million acres of forests was burnt up in the West (Wildland Fires, 1). This figure is two times the ten year annual average, and it does not look like next summer will be any better (Wildfire Season, 1).
Forests have covered the earth for millions of years, providing habitat and food for animals and humans. These forests have stabilized different ecosystems and have continued the natural cycle that keeps plants and animals in check. The discovery of fire changed all of this. It was the beginning of deforestation, a process that has continued and increased over the last 200,000 years. Humans are the responsible party for the deforestation that has occurred. Humans discovered that animals could be driven with fire. This led to accelerated forest loss due to uncontrolled burning for hunting use (Miller & Tangley 1991: 28). Agriculture was the next problem
