Native to Europe and Asia, cheatgrass is an invasive species of grass that is causing problems in North American fields. The plant quickly dominates fields that it has invaded and drives out other plants. This can cause, among other problems, severe damage to animal habitats and to scenic areas. Several solutions to the cheatgrass problem have been proposed by ecologists.
One option is to encourage animals such as cattle to feed on cheatgrass. Cattle and other livestock are known as grazers because they graze, or eat. small portions of grass or other plants throughout the day. If grazers were released in fields where cheatgrass is prevalent, the cheatgrass would be reduced That would create room for native species to reestablish themselves and flourish. This plan is appealing because cheatgrass is most prevalent in areas of North America where cattle and other livestock are raised.
Another option is to burn the cheatgrass off the fields with controlled fires. This plan has the advantage of eliminating vast amounts of cheatgrass in a short time Cheatgrass, it turns out? is a highly flammable plant: it burns much more easily than the native plant species that have been crowded out. Strategically set fires could bum away the cheatgrass where it has come to dominate, creating space so the newly cleared fields could be reseeded with native grasses and other plants.
Still another option is to introduce a fungal parasite that specifically attacks cheatgrass. In Europe and Asia, where cheatgrass is a native species, there is a species of fungus that has the ability to prevent cheatgrass from reproducing. Introducing this fungus in North American fields where cheatgrass has proliferated could slow the spread of cheatgrass, making it possible for native species to better compete against cheatgrass.
Both the reading passage and the listening discuss the method to overcome the cheatgrass problem. The former says there are three methods that can be used to eradicate the cheatgrass, but the latter contradicts each of these points.
First of all, the reading passage claims that encouraging animals such as cattle to feed on cheatgrass helps to destroy the cheatgrass. However, the lecturer in the audio contends that there are other kinds of plants are also there and since cheatgrass is not the first choice of the grazers, it will affect adversely.
Second, the reading passage asserts that cheatgrass can be eliminated by burning off the fields with controlled fires. Notwithstanding, the audio argues that since cheatgrass produces too many seeds which usually stay below the surface the fire cannot harm them. Moreover, the audio argues that since seeds can germinate even after several years, burning the field might not work.
Third, the reading passage maintains that by introducing a fungal parasite that specifically attacks cheatgrass, we can get rid of the cheatgrass problem. Nevertheless, the lecturer on the listening side insists that since the fungal parasite and the cheatgrass have been living together for a thousand years, cheatgrass has already developed resistance to the fungal parasite. So introducing a fungal parasites is not likely to help us from overcoming the cheatgrass problem.
