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 is about the possible ways to save the western United States forest from the rage of P. ramorum. It provides three supporting ideas in order to bolster its claim. However, the professor says, these ways are rather ineffective and also worsening the situation. She refutes each of the passage reasoning.
First, the article asserts that preventing the dispersement of P. ramorum spores is an effective treatment. But, the lecturer denies this theory. She explains, these spores are not just spread only by humans assistance. According to the study, during rainy season, they are carried out by the rain water and washed into the stream in the long distance. Moreover, the spore spread by water is harder to control.
Second, the reading states that it is possible to protect oak tree by injecting fungicidal. However, the narrator refutes this proposition. She describes, the fungicidal injection works only when it is injected into the trunk of the tree. In addition, the effects of the injection last only few months and the process needs to be repeated. Furthermore, this approach is not practical as it is works only a part of the forest because injecting each and every oak tree is rather expensive and impractical task.
Third, the written excerpt claims that the approach of clear cutting is an effective way to curb the bad effects of P. ramorum. This position is incoherent with the professors view. She says, when destroying vegetation, some healthy and rare species of tree might have been chance to eliminate. Moreover, there are many rare species are present in western United States that fall in great danger and causes an ecological disaster to the whole forest.
