In 1995 a microscopic fungus called Phytophthora ramorum, or P. ramorum, was first detected in the forests of the western United States. P. ramorum infects trees and causes particularly serious damage in oak trees: in many infected oaks, leaves wither rapidly, large cracks appear in the bark, and the trees die. A spread of P. ramorum represents a serious threat to the forests in the western states. Several methods of protecting the forests have been proposed.
First, stopping P. ramorum spores from spreading would surely be an effective method. Spores are small particles through which all fungi, including P. ramorum, reproduce. Researchers have discovered that many P. ramorum spores can be found along hiking or biking trails, suggesting human-assisted spread by way of shoes and bicycle tires. A few measures to prevent such human-assisted spread—like encouraging hikers to wash their shoes and installing new bike scrubbers on bicycle trails—would be an effective and low-cost way to stop the spread of P. ramorum.
Second, there are a few fungicidal (fungus-fighting) chemicals that can be used to protect the oak trees. Some of these chemicals stimulate the oak trees’ natural defenses against the P. ramorum fungus and have been found in small-scale tryouts to significantly reduce the likelihood that the oaks will be infected.
A third way to fight P. ramorum is a practice called clear-cutting. This approach starts with cutting and burning the diseased oaks, but it also involves cutting and burning the seemingly healthy vegetation (bushes and other kinds of trees) surrounding the oaks. This is done because some of the surrounding plants and trees may be infected even though they do not show any symptoms of the disease. Clearing large areas of vegetation in places where diseased trees are found is often an efficient measure to stop the spread of infections.
The reading passage and the listening discuss about the methods of controlling Phytophthora ramorum. Despite that, the professor in the lecture thinks the proposed methods are ineffective and impractical. She casts doubt on every single points the reading makes and provides explanations to support her idea.
To begin with, the writer claims that humans can assist to control the spread of P. ramorum by taking actions such as washing their shoes and installing new bike scrubbers. However, the lecturer points out this solution only help little. Because the spread of P. ramorum is mainly resulted from the rain fall which brings the P. ramorum to long-distance and down to the stream. As a result, she can not give a nod to the author in terms of the first point.
In addition, the reading suggests the application of fungicidal chemicals can protect the oak trees. The professor, on the other hand, argues that, fungus-fighting chemicals have to be used every few months to make this method effectively. It is not practical to apply the chemicals in the forests that have thousands of oak trees. Not to mention the expensive cost it would take when using this practice. Apparently, she disproves its counterpart in the reading.
Over and above that, the author mentions cutting and burning the diseased oaks and the surrounding of the oaks to fight P. ramorum whereas the lecturer indicates that the healthy plants would be destroyed by this method. There are rare species of trees in the United States and it would not be recovered if they are damaged. In other words, this would harm the eco-system. Therefore, she does not support this argument.
It is obvious that the writer and the professor have conflicting views on this topic.
