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 and the lecture are both about protection methods of trees from P. ramorum, a microscopic fungus which causes serious damage to oaks. The author of the reading provides three possible solutions for this problems. The lecturer challenges author’s claims. He says that none of the suggested solutions are applicable.
To begin with, the author argues that blocking spread of fungus spores can prevent tree destruction. The article mentions that spores transmit through human shoes and bike wheels, so shoes washing and bike scrubbers might become a possible solution. This specific argument is challenged by the lecturer. He claims that most part of spores spread among big area through water streams. Additionally, he says that control of water streams is difficult, so solution is not suitable.
Secondly, the writer suggests fungus-fighting chemicals as a fix for problem. They will not only kill the fungus, but also provoke trees’ natural defense mechanism. The lecturer, however, rebuts this by mentioning medication need to be injected directly and its duration for only couple of months. He says that it might be effective for few infected trees in park, but not for whole forest, because high financial expenses are required to inject enormous amount of trees every couple of month.
Finally, author of the passage posits that clear-cutting and burning of infected trees might be a solution. However, lecturer opposes by saying that cleaning will cause grater damage to environment than T.ramorum. This is because besides infected oaks other healthy and rare trees, which cannot grow back easily, will be cut.
