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.
The reading states that ecologists have been suggested three solutions for controling and solving the problem caused by cheatgrass. The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
The author argues that releasing some grazers such as cattle which feed on grasses, can be a good option to reduce the population of cheatgrass and providing spaces for native plants. Conversely, the lecturer brings up the idea that cheatgrass is not the preferred grass for cattle to eat. They eat other presented grasses at first and then feed on cheatgrass. As a result, this approach may have oppposite effect and reduce the population of native plants.
Furthermore, the reading passage holds the view that by burnning cheatgrass that are more ignitive than other plants, fields can be provided for the growth of native grasses. On the contrary, the professor underlines the fact that cheatgrasses burry many seeds below the surface and after the elimination of surface plants by fire, they will give rise and flourish new plants, so it will not be a practical approach to solve this problem.
Finally, the reading states that by inserting a fungal parasite, which brings about problems for cheatgrass in their native locations, into these places the reproduction of cheatgrasses can be reduced. In contrast, the speaker dismisses this issue due to the fact that this parasite only have the ability to attack the weak and sick plants. Strong plants resist towards parasite's attack and can stay alive. As a result this procedure cannot be efficient to reduce the spread of cheatgrass.
