Free Example of Eco-region Internet Research Essay

The city of Des Moines is found in Iowa State. It is one of the biggest cities in this region. It falls under the Des Moines Lobe eco-region. This is one of the flattest regions in the state of Iowa.The eco-region has distinctive glacial stage landforms which are cultivated for agricultural activities. Most of the land is level except for some moraine ridges in northern areas. A lot of land has been put into farming leaving only a small fraction of the wetland region. The region’s average annual temperature is 500F (100C). It experiences the lowest temperatures in January which may fall to a low of 260F to 300F (-30C to -10C). Iowa experiences lots of rainfall all year round but most precipitate is achieved in spring. Spring starts around April and lasts for three months. During this time, the eco-region experiences high rainfall that poses the threat of tornadoes and flooding. Spring season marks the start of the rainy season which lasts for about six months.

 The abundant rainfall is crucial to the agriculture of the Iowa state. Iowa is the 31st wettest state in the US. Its average annual rainfall is 865mm. Rainfall is experienced in all seasons, but spring and summer months are the wettest. Iowa’s snowfall is high in the winter but it is not as high as other states found in the far north. The humidity of this region is similar to that of other regions in the north. But it is higher compared to those regions in the far west.

The Des Moine Lobe eco-region comprises of a variety of organisms (producers and consumers). The plant cover is high is most areas though it comprises of crops with only few areas under natural vegetation which mainly consists of trees. Other organisms (producers) which are evident in this region are food plants and livestock. The main activity of this eco-region is agriculture; the region is highly productive and consists of few consumers who comprise the local people and their livestock. The wild species found in this region range from reptiles, mammals and birds.

Human interactions with this ecoregion have both positive and negative impacts. This positive interaction is mostly exhibited through agricultural activities. The gentle terrain and amicable rainfall throughout the year has made the region one of the most productive areas in the state of Iowa. The terrain makes it possible for mechanization of agriculture as farming trucks are able to do most the farm work such as cultivating, planting and harvesting. The streams and rivers provide water for irrigation. This ecosystem contained a high percentage of forest cover when Iowa  became a state but with time it has reduced by over 50%. The types of tree found in this region are oak, basswood, hackberry and bitternut hickory. People have contributed greatly to the reduction of trees in this region. Harvesting of timber products have resulted to cutting of many trees most of which are old species such as Oak. Grazing fields and woodlands have been tiled to make way for farming activities.

 Grazing of livestock has led to loss of soil fertility, decrease of regeneration capacity and environmental degradation. However, the deep ravines and forest covers have enabled the original tree species such as the red oak to grow well. Wildlife on the other hand benefits from the remaining natural covers. Those animals that benefit the most are songbirds, turkey and deer which are found in numbers in this region.
