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.
In this set of materials, the reading and listening both discuss the chaeatgrass, the invasive grass in North American fields. The article strongly postulates that due to the hazardous effects of grass on animal and nature, it should be eradicated, and endorse three solutions to get rid f grass. However, the lecturer mentions that methods used in the reading are dubious and impractical and would not be successful, and gainsay them.
First and foremost, the reading begins by asserting that it grazers like cattle are placed on the cheatgrass fields, they would feed on the grass and reduce the proliferation of cheatgrass by providing more room for native vegetation to grow. On the other hand, the lecturer rebuts this point by insisting that grazing animals do not prefer to graze on cheatgrass especially when they have other feed available. He exemplifies that if cattle are left on fields with cheatgrass, the cattle will definitely eat the cheatgrass but only after feeding on native grass and destroying the native vegetation first. Consequently, this solution would have opposite effect, because the field will be lefty with fewer native plants and plentiful cheatgrass.
Furthermore, the lecturer posits that when cheatgrass grows, it germinates innumerable number of seeds and many of them are pushed down to the earth. Therefore, when fire is ignited in cheatgrass field, they would just burn the cheatgrass located on surface, the seeds that below remain protected and they will grow again even after the fire is extinguished. Consequently, the cheatgrass growth will be outgrown again. these points clearly refute the writer's implication that a controlled fire could reduce the extensive growth of cheat fire as grass is highly combustible.
Ultimately, the writer wraps up its arguments by declaring that parasitic fungus that shares same habitat with cheatgrass is proven to kill the cheatgrass. Therefore if that parasite is grown in North America, the growth would be reduced. Not surprisingly, the lecturer takes an issue with that by contending that parasitic fungus is known to live with cheatgrass for thousands of years. So cheatgrass has developed the resistance against them. Moreover, they will only kill the weak and sick grass not the healthier and stronger grass. As a result, this solution is ineffective too.
