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 article asserts that there is a big problem with cheatgrass, an invasive non-native plant from Europe and Asia which dwells in North America and threats the native plant species and even affects negatively the native animal habitat. It propses three methods to fight against cheatgrass. On the other hand, the professor mentions that none of those methods are likely to control the cheatgrass propagation well.
First, the reading states that encouraging the cattles to eat cheatgrass will be an effective way to eradicate cheatgrass from the North America fields. Conversely, the lecturer rebuts this opinion by explaining that cattles prefer to eat native grass and unfortunately they eat native grass completely first and then they eat partially cheatgrass. This method will provide cheatgrass with more space and resources withoput a rival through which it could propagate enormousely and cover all fields. Therefore, he directly reject this idea.
Second, the writer suggests that by controled burning fields, cheatgrass, which is a flammable plant, they would wipe out from the field. Controversially, the lecturer mentions that cheatgrass produces myriad seeds, which they will germinate years afterward. The seeds and palnts on the surface may burn but the underground seeds will be remained intact which are able to produce new progenies over the next years, the professor explains. With this justification this solution does not hold water.
Thrid, the author avers that introducing a fungal parasite can kill the cheatgrass and will clear up the fields from this invasive unwanted gest. However, the speaker points out the cheatgrass and this fungus have been living together in Asia and Europe for thousands years; as a result, cheatgrass has developed resistance to cheatgrass. Indeed, this parasite is able to kill only the sick cheatgrass and the healthy grass is in a safe place. Consequently, this method won' taddress this problem.
