University’s Successional Plot’s Soil P.H. Meredith Hamilton Biology- Westover September 30‚ 2011 Abstract The question of this study pertained to the amount of vegetation that was occurring on each of the succession plot’s ground floor. There are three successional plots in Winthrop University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount

Chapter 11 : Soil: The Foundation for Land Ecosystem Chapter 11 Brooke Settles Chapter 11 discusses three major practices that expose soil erosion and how they can be corrected . The three are Over- cultivation‚ Overgrazing and Deforestation. These are each all major problems in creating an unsustainable society. The good thing is that each of these causes of erosion can be corrected to create a more sustainable society. First there is Overcultivation which is the practice of repeatedly

implemented in response to the resilience and vulnerability of a selected ecosystem? The Mojave Desert is a world famous desert that occupies a significant amount of California and smaller parts in surrounding states. Covering thousands of square kilometers‚ the ecosystems can range from 100 meters below sea level up to 2000 meters above sea level. The biophysical interactions within these ecosystems such as earth movements‚ soil formation‚ weather and climate lead to very diverse environments‚ along
