Ecological Succession: Temperate Coniferous Forest By: Jane Doe Mrs. Zerbi Period 8 The biome focus is the Temperate Coniferous Forest. They are typically found in the northern hemisphere and northern latitudes as well as in mountainous areas, such as the Rocky Mountains, Alps and Ural Mountain ranges. Organisms that you may find are: Elk. Bears, Wolves, Deer, Rabbits, Cougars, Beaver, Pine Trees, and Ferns. The biome is located in the United States, Canada, several parts of Europe and Russia. The largest threat to this beautiful ecosystem other than habitat destruction due to human activity is wildfires. The aftermath of a wildfire looks like this: Wildfires are naturally occurring and often happen with lightening strikes and drought conditions. In Colorado for example, the pine beetles have already killed many trees and have left the forest vulnerable to wildfire destruction. Every year this happens in California, but one of the worst disasters happened in Yellowstone National Park. Russia had similar problems three years ago with significant damage to ecosystems there. Organisms left: Not much would be left. The area would not be suitable for life without plants to provide food. Organisms that may be present after secondary ecological succession begins include: small plants, weeds and some insects. This process begins with small plants and insects re-introducing themselves into the coniferous forest ecosystem. The fire will leave nutrients behind and in fact will allow some seeds to open for new growth which is possible since soil is already present. At this time we are still looking at low biodiversity. Over half of the biodiversity has come back to the forest by the time we get to the third stage. We will see some smaller mammals such as mice, squirrels and rabbits enter the area as well as birds and most insects are back. Here we start to see bushes and small trees, mostly saplings. This provides more habitats for more animals. Plants have quickly moved in and are taking up areas with a lot of sunlight previously covered in shade from the trees. This is a highly competitive time for plants and animals as they continue to populate the area. Organisms in this stage have all returned including some of your larger animals like elk, deer, wolves, bears, buffalo, and birds of prey such as the eagle. This is the last stage of succession where you have a complete selfsustaining ecosystem that is in equilibrium. All the biodiversity has returned which is important for the likelihood of an ecosystem rebounding after a natural catastrophe. By this point all the producers, consumers and decomposers have returned.
