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.
The reading passage and the lecture both discuss the problem of P. ramorum and damages that it has on oak trees. In the reading part, the author mentions that several ways have been suggesting for protecting them. In the listening part, however, the speaker challenges what the author ststes and rebuts the reasons.
To begin with, as mentoned in the article, the author sets forth that it could stop spreading if people pay more attention to their shows and cleaning them or cleane the fungies from their bick. Nevertheless, in the listening part, the speaker refutes the reasons asserting that it probebly have benefits, but it coud not be effective very much and it does not hug impact on spreading them. In addition, water spread them and controling of water that wash them would be hard.
Secondly, the author points out that chemical stimulation with injection to the trees might be helpful; nonetheless, the author flatly sontradicts the idea and contends that injection in the urban eria could be happend, whereas, there are enormous forest that people cannot inject to each of the tree speratly and also in it would be costely.
Finally, the author claims that clear-cuttind could be one of the solutions; in contrast, the professor is of the opinion that it does not make sense or it could enffect on the trees that they are already rare and near to extinct; therefor, it could destroy variety of species and could has inffect on healty trees rather than unhealthy ones.
