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 article and the lecture talk about the possible solutions to eliminate the spreading of cheatgrass. The author of the article suggested three possible solutions that might solve the problem. The lecturer, on the other hand, stressed that the methods suggested in the article are not likely to work effectively.
To begin with, the article stated that the first method can be used to reduce the growth of cheatgrass is encouraging livestock feed on the cheatgrass. However, The lecturer argued that grazers do not prefer cheatgrass. Furthermore, he pointed that grazers will eat the other kinds of grass first, leaving behind cheatgrass. According to the lecturer, this method might have opposite effect.
Moreover, the article claimed that using fire might deter the growth of cheatgrass. The article states that fire should be under control to obtain the desirable effect. In contrast, the lecturer responded that fire will just remove the cheatgrass from the soil surface. He added that cheatgrass usually produce many seeds that push down below the surface, therefore fire cannot harm the seeds of cheatgrass.
Finally, the author of the article pointed that fungal parasite can be used to eliminate cheatgrass. The article suggested that fungal specifically attack cheatgrass. Whereas, the lecturer claimed that fungal parasite and cheatgrass have been living together for long time. He stated that cheatgrass formed a type of resistance against fungal. Therefore, only weak and sick cheatgrass can be harmed by fungal parasite.
