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 introduces cheatgrass, a type of grass that invades and drives out other species of plants at a fast pace. The author proposes three solutions to control and destroy this specie. However, the professor argues against these suggestions pointing out that it's unlikely for them to be effective.
First, the reading claims that by releasing grazers in fields, which cheatgrass is prevelant, the grazers would consume the cheatgrass, allowing for other species to flourish. The professor refutes this notion explaining that grazers don't prefer cheatgrass. Hence, the grazers will mostly eat the native species rather than the cheatgrass, leading to fewer amount of native plants.
Second, the passage states that by burning the cheatgrass with fire we can get rid of the invasive species and then plant other plants instead of them. But, the lecturer explains that this solution may work for plants on the surface of the ground but it wont be effective for seeds that are under ground therefore, protected from the fire. He states that the cheatgrass can regrow and germinate using the surviving seeds years later.
Third, The article proposes that by using a type of fungus effective against cheatgrass the species can be controlled allowing the native species to prosper. The professor argues against this point stating that cheatgrass is somewhat resistant to the fungus so only the weak grasses are affected by the fungus and the healthy cheatgrass survive even in the presence of this parasite. Therefore, this solution is not efficient as well.
