Introduction: The aftermath? Methods and Materials Why observe this phenomenon? Effects of fire on soil References: Acknowledgements: Conclusion: Department For questions you can contact Adetilewa at and Brandi at Post fire management can have a negative impact on the soils being in some cases even more severe than the fire itself. Salvage logging (SL) is a common management technique in fire affected areas , comprising the extraction of the burnt wood and in many cases using heavy machinery dragging the trunks over soil, leading to a consequent increase n its vulnerability erosion and soil degradation. In 2013, research was done to see the effects of salvage logging on the soil. Some see this process as an economic move to restore what has been lost but many wonder if this is the right move. It was shortly discovered after research that the soil did poorly . There was an increase in bulk density, a decrease in aggregate stability, decrease in field capacity, decrease in organic matter and a decrease in nitrogen content. The heavy machinery used for this logging treatment was found to be an additional cause of the decrease in soil richness. With research that we have studied, we came to a conclusion that fire whether it be natural or man made, it is always safer to have a contingency plan in place on how we can recover from a environmental disturbance like fire. Since we cannot prevent a natural fire from happening and we see that over treatment of the soil only makes it worse. We truly believe that for the area to recover will allow for the soil to get back or at least close to what it once was. Initially, we were going to carry out this experiment by driving to the National Rocky Mountain Park and Chautauqua park in Boulder due to forest fires occurring at least one time at these locations. We were going to collect soil samples and test the pH to determine whether the soil was too acidic or basic to sustain the growth of plants. Due the pandemic that broke out in late February, we were advised against this and decided to do a secondary research on the ecological effects of fire. Two research papers we had been studying caught our attention and we decided to proceed with them instead and hopefully use them to back up our research once the stay home order had been lifted. Over the years, the earth has experienced multiple forest fires and to many who have experienced this phenomenon, it can be scary! Many have speculated that this was a sign of global warning, an act of human terror and some even named it the end of time. In order to fully get on board with any of these speculations, one must wonder if there is a natural origin to these fires. There are cases where forest fires help bring about the seeds of matured plants (1) and areas that are dry in wood and air are always prone to fires. This natural phenomenon whether it be a part of the ecosystem, or as a result of a change in the ecosystem, needs to be studied so that individuals and our society will learn how to sustain our This particular study took place in an eucalyptus forested area near the Namadgi National Park in Australia. The area was divided into 8 areas and all except 2 (control sites) were burnt at different intensities. What was observed from this was that the pH of the soil increased with temperature and small variations were seen in the soil texture. Low intensity fire fostered soil water repellency. This persisted and increased progressively but by the ending of the research it decreased. After treatment of the soil, it became wettable again. 1 Granged , A., Jordan, A., Zavala, L., Munoz Rojas, M., and Mataix Solera, J.

Fire is seen as a destructive element that can ravage a large amount of biomass and cause effects such as post fire soil erosion, pollution and water runoff. So, when a place that is filled with natural resources like the Amazon forest in Brazil, Peru, Colombia, Ecuador and Bolivia is exposed to such intense form of energy, it can get many people worried. This was why we thought it would be important to study the effects fire has on the soil, the air and how animals who occupy these areas are able to either flee of adapt the phenomenon.
