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 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 Which would create room for native species to re-establish 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 from 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 can 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 and the writing are both about the Cheatgrass which is a permanent type of grass species that is causing the problem to other habitants of the territory. The author points out that some experts suggested solutions to the reduction of this plant and explained it in detail. The lecturer in the listening passage disagrees. He believes that the solutions provided by the author are not practical and do not work well.
First, the author claims that the Cheatgrass should be introduced to the pasture of the cattle because these mammals are known to be grazers. The lecturer, however, disagrees with this viewpoint. He says that even though the cattle prefer to eat grasses, they will dislike the Cheatgrass. He goes on to say that as a result, only native grasses that mammals eat often will decrease.
Second, the author states that people could burn the Cheatgrass in controllable fire areas, so this burned site will be empty and create a new habitat for other species, which in turn will decrease the Cheatgrass population. The professor in the listening passage is doubtful that this is accurate. He suggests that the seeds of this particular plant germinate beneath the underground. If the fire burns the remaining Cheatgrass, as a result, the sprout of this plant will start to grow after the fire.
Finally, the author notes that a fungal parasite, which is an enemy of the Cheatgrass, will reduce its increasing numbers. The lecturer rebuts this argument. He says that even though the parasite is not aligned with a certain plant, they have been in the same habitat for a long time. Furthermore, he argues that some Cheatgrass plants may have resistance to the fungal parasites because it can only harm weak and sickly plants.
To sum up, both the author and the lecturer hold conflicting views about the Cheatgrass plant.
