In the 1950s Torreya taxifolia, 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 to conduct research on Torreya. This research can then be used to ensure the continued survival of the speces.

The reading and listening materials discuss about the ways to solve the decline of torreya tree. The article mentions three possible methods to address the declining population of this tree. however, the speaker rejects all of them and claims that they are unlikely to be successful.

First, the reading suggests that people can reestablish torreya in the same location of north florida, where the microclimate is favorable for its growth. Nevertheless, the professor argues that the climate has changed in large region of florida, due to the increasing temperature caused by global warming or the drier weather condition contributed by the drained wetlands through the region. therefore, the professor believes that the microclimate is no longer suited for torreya in north florida.

In addition, another way proposed by the author to solve the tree decline is to move torreya tree to a totally different location, which is further north than the past. On the contrary, the professor considers that this process could have unpredicted outcomes. She illustrates another type of tree as an example to explain her point. In her words, the black locust tree that was moved to a new environment spread quickly and killed many local trees, some of which were endangered or becoming extinct. therefore, the speaker holds that this method will not succeed.

Finally, the writer brings up that scientists could preserve the torreya tree in research center in order to protect it and conduct research. however, the professor points out that the tree in the center could not resist diseases and survive in a long term. it is because the research center does not have the capacity to support a large population ensuring the tree’s genetic diversity, which is very necessary for torreya tree’s survival.
