In the 1950s Torreya taxifoha, a type of evergreen tree once very common in the state of Florida started to die out. No one is sure exactly what caused the decline, but chances are good that if nothing is done, Torreya will soon become extinct. Experts are considering three ways to address the decline of Torreya.
The first option is to reestablish Torreya in the same location in which it thrived for thousands of years. Torreya used to be found in abundance in the northern part of Florida, which has a specific microclimate. A microclimate exists when weather conditions inside a relatively small area differ from the region of which that area is a part. Northern Florida’s microclimate is very favorable to Torreya’s growth. This microclimate is wetter and cooler than the surrounding region’s relatively dry, warm climate. Scientists have been working to plant Torreya seeds in the coolest, dampest areas of the microclimate.
The second option is to move Torreya to an entirely different location, far from its Florida microclimate. Torreya seeds and saplings have been successfully planted and grown in forests further north, where the temperature is significantly cooler. Some scientists believe that Torreya probably thrived in areas much further north in the distant past, so by relocating it now, in a process known as assisted migration, humans would simply be helping Torreya return to an environment that is more suited to its survival.
The third option is to preserve Torreya in research centers. Seeds and saplings can be moved from the wild and preserved in a closely monitored environment where it will be easier for scientists both to protect the species and conduct research on Torreya. This research can then be used to ensure the continued survival of the species.
The lecturer challenges the topic proposed in the reading that experts considers three ways to address the decline of Torreya. And she thinks none of these options are satisfactory solutions.
First, the article suggests an option is to reestablish Torreya in the same location in which it thrived for thousands of years. However, the professor points out that the coolest dampest microclimate is strongly affected in a larger region because global warming increases the temperature there and wetlands are drained. Then the area around northern florida is drier, which is not suited for Torreya to survive any more.
Second, the essay indicates another solution is to move Torreya to an entirely different location, far from its florida microclimate. But the lecturer argues that another example about a type of tree helped by people is unsuccessful. The tree was spread quickly and killed considerable other trees and plants, which have been in danger already. Thus, human help would bring unpredicted outcome in a new area.
Third, the passage supposes another option is to preserve Torreya in research centers. Nevertheless, the professor supports that Torreya's population need to be pretty large and they have to be genetically diverse to resist diseases, which could be satisfied from wild. By contrast, research centers do not have the capacity to diverse them genetically. Hence, they cannot survive in disease in a long term.
