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. Cleaning large areas of vegetation in places where diseased trees are found is often an efficient measure to stop the spread of infections.
Both the reading and the lecture discuss how the western United States forests have been infected by P. ramorum fungi. The author suggests three possible methods to stop the further spread of the p. fungi. In the listening portion, however, the lecturer believes none of the mentioned tactics is feasible, therefore, infective.
First of all, preventing P. ramorum spores from reproducing would effectively solve the problem, the author asserts. In fact, some scholars have found that P. ramorum spores typically live along hiking and biking trails. So, educating people some will limit the spore’s transmission such as washing their shoes or replacing their bike scrubbers every now and then. In contrast, the lecturer disagrees with this belief by stating that even if people followed the instructions would not cause a huge impact. This is because some experts have discovered that spores are being picked up by the streams when it rains, which is something really hard to control.
Second of all, the writer suggests that using fungicidal can save the oak trees, especially since such chemicals will stimulate the oak tree's immunty which, in turn. will help them to fight back. On the other hand, the speaker argues with this statment. She says that it is true that injecting the fungicidal will benefit the trees, but farmers have to inject them every few months. Furthermore. the U.S. forests usually contain a countless number of trees which, in turn, will make cost a lot of money.
Finally, the author wraps his argeument by explaining that fightting P. ramorum can be managed by using the clear-cutting strategy, which means cutting the infected trees along with the surrounding plants. The speaker argues this point by mentioning that conducting such method will cause more ecological catastrophes. She elaborates that some vegetation is rare and it's hard for them to grow back. Therefore, cleaning large areas of vegetation in places where diseased trees are found is not eco-friendly and will make the situation worse.
